If you've read anything about or studied Search Engine Optimization, you've come across the term "backlink" at least once. For those of you new to SEO, you may be wondering what a backlink is, and why they are important. Backlinks have become so important to the scope of Search Engine Optimization, that they have become some of the main building blocks to good SEO. In this article, we will explain to you what a backlink is, why they are important, and what you can do to help gain them while avoiding getting into trouble with the Search Engines.
[44] Matteo Pasquinelli reckons the basis for the belief that PageRank has a social component lies in the idea of attention economy. With attention economy, value is placed on products that receive a greater amount of human attention and the results at the top of the PageRank garner a larger amount of focus then those on subsequent pages. The outcomes with the higher PageRank will therefore enter the human consciousness to a larger extent. These ideas can influence decision-making and the actions of the viewer have a direct relation to the PageRank. They possess a higher potential to attract a user's attention as their location increases the attention economy attached to the site. With this location they can receive more traffic and their online marketplace will have more purchases. The PageRank of these sites allow them to be trusted and they are able to parlay this trust into increased business.

“Google itself solely decides how much PageRank will flow to each and every link on a particular page. In general, the more links on a page, the less PageRank each link gets. Google might decide some links don’t deserve credit and give them no PageRank. The use of nofollow doesn’t ‘conserve’ PageRank for other links; it simply prevents those links from getting any PageRank that Google otherwise might have given them.”
Retargeting is another way that we can close the conversion loop and capitalize on the traffic gained from the overall marketing campaign. Retargeting is a very powerful display advertising tool to keep your brand top of mind and keep them coming back. We track every single touch point up to the ultimate conversions and use that data to make actionable recommendations for further campaign optimization.
Now that you know that backlinks are important, how do you acquire links to your site? Link building is still critical to the success of any SEO campaign when it comes to ranking organically. Backlinks today are much different than when they were built in 7-8 years back. Simply having thousands of backlinks or only have link from one website isn’t going to affect your rank position. There are also many ways to manage and understand your backlink profile. Majestic, Buzzstream, and Moz offer tools to help you manage and optimize your link profile. seoClarity offers an integration with Majestic, the largest link index database, that integrates link profile management into your entire SEO lifecycle.   
Thanks for the info on nofollow and pagerank. It makes sense that this will always be a moving target less everyone will eventually game the system until it’s worthless but at the same time it’s worth it to know a few tricks. I still have open concerns on how freshness of content factor in, the only time i’m ever annoyed by search results these days is when the only links available (on the first page at least) are articles from 4 years ago.
As digital marketing continues to grow and develop, brands take great advantage of using technology and the Internet as a successful way to communicate with its clients and allows them to increase the reach of who they can interact with and how they go about doing so,.[2] There are however disadvantages that are not commonly looked into due to how much a business relies on it. It is important for marketers to take into consideration both advantages and disadvantages of digital marketing when considering their marketing strategy and business goals.
Matt, you don’t mention the use of disallow pages via robots.txt. I’ve read that PageRank can be better utilised by disallowing pages that probably don’t add value to users searching on engines. For example, Privacy Policy and Terms of Use pages. These often appear in the footer of a website and are required by EU law on every page of the site. Will it boost the other pages of the site if these pages are added to robots.txt like so?
Matt, in almost every example you have given about “employing great content” to receive links naturally, you use blogs as an example. What about people that do not run blog sites (the vast majority of sites!), for example an E-Com site selling stationary? How would you employ “great content” on a site that essentially sells a boring product? Is it fair that companies that sell uninteresting products or services should be outranked by huge sites like Amazon that have millions to spend on marketing because they cant attract links naturally?
I’m in the wedding industry and recently a Wedding SEO Company began touting PageRank sculpting as the missing link for SEO. So naturally I got intrigued and searched for your response to PageRank sculpting and your answer for anything SEO-related is always the same. “Create new, fresh, and exciting content, and organically the links and your audience will grow.”
There is no secret that getting hiqh-quality backlinks is your website’s way to better ranking in Google. But how to differ good link from the bad one? Carefully choosing backlinks is a very tremulous and important task for everyone who wants to optimize their sites. There are a lot of different tools which can help you to check whether your backlinks are trustful and can bring your website value. 
Before online marketing channels emerged, the cost to market products or services was often prohibitively expensive, and traditionally difficult to measure. Think of national television ad campaigns, which are measured through consumer focus groups to determine levels of brand awareness. These methods are also not well-suited to controlled experimentation. Today, anyone with an online business (as well as most offline businesses) can participate in online marketing by creating a website and building customer acquisition campaigns at little to no cost. Those marketing products and services also have the ability to experiment with optimization to fine-tune their campaigns’ efficiency and ROI.
Also given that the original reasons for implementing the ‘nofollow’ tag was to reduce comment spam (something that it really hasn’t had a great effect in combatting) – the real question I have is why did they ever take any notice of nofollow on internal links in the first place? It seems to me that in this case they made the rod for their own back.
Brian, just wanted to start off by saying great informative article, you had a lot of great of insight. I see it was mentioned a bit in the above comments, about the infographic, but I thought it is a great idea to include a textbox under the infographic with the coding that could be copied to be pasted on blogs (thus, earning additional backlinks from other websites). I’ve also noticed many infographics that have “resources” or “references” included in the image. My understanding is currently it is not recognized by google, because of the image format, but I foresee one day Google may be able to update their algorithm to recognize written text inside of an image, and thus potentially adding value to the written text in the image. What are your thoughts on that idea?
You may not want certain pages of your site crawled because they might not be useful to users if found in a search engine's search results. If you do want to prevent search engines from crawling your pages, Google Search Console has a friendly robots.txt generator to help you create this file. Note that if your site uses subdomains and you wish to have certain pages not crawled on a particular subdomain, you'll have to create a separate robots.txt file for that subdomain. For more information on robots.txt, we suggest this Webmaster Help Center guide on using robots.txt files13.
The development of digital marketing is inseparable from technology development. One of the key points in the start of was in 1971, where Ray Tomlinson sent the very first email and his technology set the platform to allow people to send and receive files through different machines.[8] However, the more recognisable period as being the start of Digital Marketing is 1990 as this was where the Archie search engine was created as an index for FTP sites. In the 1980s, the storage capacity of computer was already big enough to store huge volumes of customer information. Companies started choosing online techniques, such as database marketing, rather than limited list broker.[9] This kind of databases allowed companies to track customers' information more effectively, thus transforming the relationship between buyer and seller. However, the manual process was not so efficient.
Business address listings on Google, Yelp, LinkedIn, Facebook, Yellow Pages, and elsewhere count as backlinks. Perhaps more importantly, they also go a long ways towards helping customers find your business! There are many, many such sites. A good way to approach this once you've gotten the biggies out of the way - Google should be your first priority - is to make a point of setting up a couple new citation profiles every week or so. Search around for updated lists of reputable business listing sites, and use it as a checklist.
And if you really want to know what are the most important, relevant pages to get links from, forget PageRank. Think search rank. Search for the words you’d like to rank for. See what pages come up tops in Google. Those are the most important and relevant pages you want to seek links from. That’s because Google is explicitly telling you that on the topic you searched for, these are the best.
In this new world of digital transparency brands have to be very thoughtful in how they engage with current and potential customers. Consumers have an endless amount of data at their fingertips especially through social media channels, rating and review sites, blogs, and more. Unless brands actively engage in these conversations they lose the opportunity for helping guide their brand message and addressing customer concerns.

Your Brand Persona and Target Audience. When you eventually start creating content, you have to know who you’re talking to and tailor your brand voice to appeal to them uniquely. If you aren’t targeting the right audience (those people who will lean in to hear what you’re saying), you won’t find success. And, if you can’t find a way to stand out, you’ll blend into the hordes of other brands competing for attention in your industry.
We combine our sophisticated Search Engine Optimization skills with our ORM tools such as social media, social bookmarking, PR, video optimization, and content marketing to decrease the visibility of potentially damaging content. We also work with our clients to create rebuttal pages, micro-sites, positive reviews, social media profiles, and blogs in order to increase the volume of positive content that can be optimized for great search results.
It doesn’t mean than you have to advertise on these social media platforms. It means that they belong to that pyramid which will function better thanks to their support. Just secure them and decide which of them will suit your goal better. For example, you can choose Instagram because its audience is the most suitable for mobile devices and bits of advice of their exploitation distribution.

Search queries—the words that users type into the search box—carry extraordinary value. Experience has shown that search engine traffic can make (or break) an organization's success. Targeted traffic to a website can provide publicity, revenue, and exposure like no other channel of marketing. Investing in SEO can have an exceptional rate of return compared to other types of marketing and promotion.
Search engines are smart, but they still need help. The major engines are always working to improve their technology to crawl the web more deeply and return better results to users. However, there is a limit to how search engines can operate. Whereas the right SEO can net you thousands of visitors and increased attention, the wrong moves can hide or bury your site deep in the search results where visibility is minimal.
For search engine optimization purposes, some companies offer to sell high PageRank links to webmasters.[40] As links from higher-PR pages are believed to be more valuable, they tend to be more expensive. It can be an effective and viable marketing strategy to buy link advertisements on content pages of quality and relevant sites to drive traffic and increase a webmaster's link popularity. However, Google has publicly warned webmasters that if they are or were discovered to be selling links for the purpose of conferring PageRank and reputation, their links will be devalued (ignored in the calculation of other pages' PageRanks). The practice of buying and selling links is intensely debated across the Webmaster community. Google advises webmasters to use the nofollow HTML attribute value on sponsored links. According to Matt Cutts, Google is concerned about webmasters who try to game the system, and thereby reduce the quality and relevance of Google search results.[40]

Thanks for the article (and lead-off links as they were good info too) but I did not quite get – if there was a penalisation by Google for sculpting – from the article or whether it was just bad practice? And also to echo what someone else asked ‘is it WORTH actually undoing this type of work on websites SEO’s have worked on’ or simply change the way we work with new sites?
In this illustration from the “PageRank Citation Ranking” paper, the authors demonstrate how webpages pass value onto other pages. The two pages on the left have a value of 100 and 9, respectively. The page with a value of 100 has two links that point to the pages on the right. That page’s value of 100 is divided between the two links, so that each conveys a value of 50. The other page on the left has three outgoing links, each carrying one-third of the page’s value of 9. One link goes to the top page on the right, which ends up with a total value of 53. The bottom right page has no other backlinks, so its total value is 50.

Changes to the algorithms that produce search engine rankings can place a heightened focus on relevance to a particular topic. While some backlinks might be from sources containing highly valuable metrics, they could also be unrelated to the consumer's query or interest. An example of this would be a link from a popular shoe blog (with valuable metrics) to a site selling vintage pencil sharpeners. While the link appears valuable, it provides little to the consumer in terms of relevance.
[43] Katja Mayer views PageRank as a social network as it connects differing viewpoints and thoughts in a single place. People go to PageRank for information and are flooded with citations of other authors who also have an opinion on the topic. This creates a social aspect where everything can be discussed and collected to provoke thinking. There is a social relationship that exists between PageRank and the people who use it as it is constantly adapting and changing to the shifts in modern society. Viewing the relationship between PageRank and the individual through sociometry allows for an in-depth look at the connection that results.
Brian, this is the web page that everybody over the entire Internet was searching for. This page answers the million dollar question! I was particularly interested in the food blogs untapped market, who doesn’t love food. I have been recently sent backwards in the SERP and this page will help immensely. I will subscribe to comments and will be back again for more reference.
Let’s start with what Google says. In a nutshell, it considers links to be like votes. In addition, it considers that some votes are more important than others. PageRank is Google’s system of counting link votes and determining which pages are most important based on them. These scores are then used along with many other things to determine if a page will rank well in a search.

Well, it seems that what this article says, is that the purpose of the no-follow link is to take the motivation away from spammers to post spam comments for the purpose of the link and the associated page rank flow; that the purpose of no-follow was never to provide a means to control where a page’s pagerank flow is directed. It doesn’t seem that shocking to me folks.
That type of earth-shattering failure and pain really does a number on a person. Getting clean and overcoming those demons isn't as simple as people make it out to be. You need to have some serious deep-down reasons on why you must succeed at all costs. You have to be able to extricate yourself from the shackles of bad habits that have consumed you during your entire life. And that's precisely what Sharpe did. 

Donating your time or money to local charities, organizations, and schools is actually a great - yet often overlooked - way of obtaining backlinks. Such organizations often have pages where they promote sponsors and donors, giving you the opportunity to net a backlink from a trusted organization. If such an organization has a donors section on their homepage, that's even better!
“NOTE: You may be curious what your site’s or your competitor’s PR score is. But Google no longer reveals the PageRank score for websites. It used to display at the top of web browsers right in the Google Toolbar, but no more. And PR data is no longer available to developers through APIs, either. Even though it’s now hidden from public view, however, PageRank remains an important ingredient in Google’s secret ranking algorithms.”

Game advertising - In-Game advertising is defined as "inclusion of products or brands within a digital game."[49] The game allows brands or products to place ads within their game, either in a subtle manner or in the form of an advertisement banner. There are many factors that exist in whether brands are successful in their advertising of their brand/product, these being: Type of game, technical platform, 3-D and 4-D technology, game genre, congruity of brand and game, prominence of advertising within the game. Individual factors consist of attitudes towards placement advertisements, game involvement, product involvement, flow or entertainment. The attitude towards the advertising also takes into account not only the message shown but also the attitude towards the game. Dependent of how enjoyable the game is will determine how the brand is perceived, meaning if the game isn't very enjoyable the consumer may subconsciously have a negative attitude towards the brand/product being advertised. In terms of Integrated Marketing Communication "integration of advertising in digital games into the general advertising, communication, and marketing strategy of the firm"[49] is an important as it results in a more clarity about the brand/product and creates a larger overall effect.

Another way to get sites to link back to something valuable on your site is by offering a free tool. A free tool could be a basic tool (like an auto loan calculator) or a scaled down version of a paid tool (like Alexa’s Site Overview and Audience Overlap tools). If the tools are valuable enough, others will link to them in their content. Plus, on free versions of paid tools, you can add call-to-actions to sign up for the full product/service which drives acquisition in addition to awareness.
Simple question – Lets say I have a blog/site with lot of outgoing links (avg 10 links per page). All the outgoing links (in the editorial content and user generated ones) are nofollowed, while all the internal links are “open”. I might have manually “opened up” some links in the editorial content because I’m so sure of their authority (ex:-google faq pages).
How does this all relate to disallows in the robots.txt? My ecom site has 12,661 pages disallowed because we got nailed for duplicate content. We sale batteries so revisons to each battery where coming up as duplicate content. Is PageRank being sent (and ignored) to these internal disallowed links as well? One of our category levels has hundreds of links to different series found under models, the majority of these series are disallowed. If PageRank acts the same with disallows as it does with nofollows, are these disallowed links are hurting our

I was exactly thinking the same thing what Danny Sullivan had said. If comments (even with nofollow) directly affect the outgoing PR distribution, people will tend to allow less comments (maybe usage of iframes even). Is he right? Maybe, Google should develop a new tag as well something like rel=”commented” to inform spiders about it to give less value and wordpress should be installed default with this attribute 🙂


Baseline ranking assessment. You need to understand where you are now in order to accurately assess your future rankings. Keep a simple Excel sheet to start the process. Check weekly to begin. As you get more comfortable, check every 30 to 45 days. You should see improvements in website traffic, a key indicator of progress for your keywords. Some optimizers will say that rankings are dead. Yes, traffic and conversions are more important, but we use rankings as an indicator.

For the purpose of their second paper, Brin, Page, and their coauthors took PageRank for a spin by incorporating it into an experimental search engine, and then compared its performance to AltaVista, one of the most popular search engines on the Web at that time. Their paper included a screenshot comparing the two engines’ results for the word “university.”
Chris_D, great question. If you have a single product page that can have multiple urls with slightly different parameters, that’s a great time to use a rel=canonical meta tag. You can use rel=canonical for pages with session IDs in a similar fashion. What rel=canonical lets you do is say “this page X on my host is kinda of ugly or otherwise isn’t the best version of this page. Use url Y as the preferred version of my page instead.” You can read about rel=canonical at http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=139394. Bear in mind that if you can make your site work without session IDs or make it so that you don’t have multiple “aliases” for the same page, that’s even better because it solves the problem at the root.
On another note, I would like to express my contempt for Google and its so called terms of service regarding the legitimate acquisition of links. why should it care if links are paid for or not? Thanks to the invention of pagerank, it is Google itself that has cancelled out reciprocal linking and has stopped people giving out links due to fear of them losing pagerank, and blogs and forums are worthless thanks to the nofollow trick. so it is now impossible to get decent links organically, without having to pay for them, and those who do give out free links are considered fools. Google has brought this dilemma on itself, and yet it seems like punishing us for trying to get links other than freely! Face facts, no one is going to link to someone without getting a link in return! google has invented pagerank which is like a currency, and so people expect to be paid for links, as giving out links devalues their pagerank and so compensation is now required. It is forcing people to use underhand methods to get links, mostly the ‘paid’ variety.
The numbers didn’t quite sit right with me because there didn’t seem to be enough juicy inbound links to the winning page. Then I noticed that two key links were missing from the 10 node chart with the PageRank metrics on it when compared to the previous chart without the metrics. The two missing links are the two coming from node 2 to node 1. Suddenly it all made sense again and it was obvious why that page won.
I agree that there is no point in trying to over analyze how the PageRank is flowing through your site. Just focus on great content. Link out when it actually helps the reader. This is what Google wants – for you to give good quality content to their users. So if you are doing that, they will reward you in the long run. No need to worry yourself with these types of link strategies.
No PageRank would ever escape from the loop, and as incoming PageRank continued to flow into the loop, eventually the PageRank in that loop would reach infinity. Infinite PageRank isn’t that helpful 🙂 so Larry and Sergey introduced a decay factor–you could think of it as 10-15% of the PageRank on any given page disappearing before the PageRank flows along the outlinks. In the random surfer model, that decay factor is as if the random surfer got bored and decided to head for a completely different page. You can do some neat things with that reset vector, such as personalization, but that’s outside the scope of our discussion.
Discoverability is not a new concept for web designers. In fact Search Engine Optimization and various forms of Search Engine Marketing arose from the need to make websites easy to discover by users. In the mobile application space this issue of discoverability is becoming ever more important – with nearly 700 apps a day being released on Apple’...

All in all, PageRank sculpting (or whatever we should call it) didn’t really rule my world. But, I did think that it was a totally legitimate method to use. Now that we know the ‘weight’ leaks, this will put a totally new (and more damaging) spin on things. Could we not have just left the ‘weight’ with the parent page? This is what I thought would happen most of the time anyway.
So, now we're getting to backlinks that have relatively little, or even negative value. The value of web directories has diminished dramatically in recent years. This shouldn't come as a surprise. After all, when was the last time that you used a web directory to find anything, rather than just doing a Google search? Google recognizes that directories don't have any real world worth, and so they don't accord much value to backlinks on them. But there is an exception to this rule. Submitting your website to local, industry-specific and niche directories can net you worthwhile backlinks. But if you can't imagine a circumstance where someone would use a certain directory, then it's probably not worth your time.
Google wasn’t happy with the Pandora’s Box it had opened. It began to fight back, with its most famous action against a network known as SearchKing, penalizing the site and some of those in the network with PageRank score reductions or actual removal from Google. SearchKing sued Google. Google won, a judge ruling that its search results were entitled to First Amendment protection as opinions.
NOTE: You may be curious what your site’s or your competitor’s PR score is. But Google no longer reveals the PageRank score for websites. It used to display at the top of web browsers right in the Google Toolbar, but no more. And PR data is no longer available to developers through APIs, either. Even though it’s now hidden from public view, however, PageRank remains an important ingredient in Google’s secret ranking algorithms.
According to the U.S. Commerce Department, consumers spent $453.46 billion on the web for retail purchases in 2017, a 16.0% increase compared with $390.99 billion in 2016. That’s the highest growth rate since 2011, when online sales grew 17.5% over 2010. Forrester predicts that online sales will account for 17% of all US retail sales by 2022. And digital advertising is also growing strongly; According to Strategy Analytics, in 2017 digital advertising was up 12%, accounting for approximately 38% of overall spending on advertising, or $207.44 billion.
Some brilliant tips and advice here, I am curious you mention the directory sites to submit to and I notice a lot of my competitors are on such sites but a lot of these sites want links back which would mean I would need pages of links on my site and that is something I don’t see on competitors sites – how do they manage that would it be all paid for or is there a trick
Example: A blogger John Doe writes a very interesting article about a sports event. Another blogger Samantha Smith doesn’t agree with John’s article and writes about it in another article for an online magazine. She links to John’s article, so that her readers can understand both point of views. John’s blog gets a valuable backlink. On the other hand, Samantha’s article gets popular and many other websites link to her article. Samantha’s website gets many new backlinks. Even though John only got one backlink for his article, the value of his backlink is increased by the backlinks Samantha’s article generated.
The numbers didn’t quite sit right with me because there didn’t seem to be enough juicy inbound links to the winning page. Then I noticed that two key links were missing from the 10 node chart with the PageRank metrics on it when compared to the previous chart without the metrics. The two missing links are the two coming from node 2 to node 1. Suddenly it all made sense again and it was obvious why that page won.
Search engines use complex mathematical algorithms to guess which websites a user seeks. In this diagram, if each bubble represents a website, programs sometimes called spiders examine which sites link to which other sites, with arrows representing these links. Websites getting more inbound links, or stronger links, are presumed to be more important and what the user is searching for. In this example, since website B is the recipient of numerous inbound links, it ranks more highly in a web search. And the links "carry through", such that website C, even though it only has one inbound link, has an inbound link from a highly popular site (B) while site E does not. Note: Percentages are rounded.
However, before learning any of that, it's important that you get a lay of the land, so to speak. If you truly want to understand the field of internet marketing, Sharpe has some very good points. In essence there are four overall steps to really understanding internet marketing and leveraging the industry to make money online. Depending on where you are with your education, you'll be somewhere along the lines of these four steps.
So, for example, a short-tail keyphrase might be “Logo design”. Putting that into Google will get you an awful lot of hits. There’s a lot of competition for that phrase, and it’s not particularly useful for your business, either. There are no buying signals in the phrase – so many people will use this phrase to learn about logo design or to examine other aspects of logo design work.
PageRank always was and remains only one part of the Google search algorithm, the system that determines how to rank pages. There are many other ranking factors that are also considered. A high PageRank score did NOT mean that a page would rank well for any topic. Pages with lower scores could beat pages with higher scores if they had other factors in their favor.
Brand awareness has been proven to work with more effectiveness in countries that are high in uncertainty avoidance, also these countries that have uncertainty avoidance; social media marketing works effectively. Yet brands must be careful not to be excessive on the use of this type of marketing, as well as solely relying on it as it may have implications that could negatively harness their image. Brands that represent themselves in an anthropomorphizing manner are more likely to succeed in situations where a brand is marketing to this demographic. "Since social media use can enhance the knowledge of the brand and thus decrease the uncertainty, it is possible that people with high uncertainty avoidance, such as the French, will particularly appreciate the high social media interaction with an anthropomorphized brand." Moreover, digital platform provides an ease to the brand and its customers to interact directly and exchange their motives virtually.[33]
Two weeks ago I changed a few internal anchor text links for a HTML SELECT Label in order to save some space in the menu bar. Today, when I saw in Google the Cache (text-version) page of my site I realized that all the links in the HTML SELECT Label cannot be followed. So I understand that Googlebot doesn’t follow this links and obviously there’s no inbound ‘link juice’. Is that so?

There are simple and fast random walk-based distributed algorithms for computing PageRank of nodes in a network.[33] They present a simple algorithm that takes {\displaystyle O(\log n/\epsilon )} rounds with high probability on any graph (directed or undirected), where n is the network size and {\displaystyle \epsilon } is the reset probability ( {\displaystyle 1-\epsilon } is also called as damping factor) used in the PageRank computation. They also present a faster algorithm that takes {\displaystyle O({\sqrt {\log n}}/\epsilon )} rounds in undirected graphs. Both of the above algorithms are scalable, as each node processes and sends only small (polylogarithmic in n, the network size) number of bits per round.

One final note is that if the links are not directly related to the subject, or you have no control over them, such as commentors’ website links, maybe you should consider putting them on another page, which links to your main content. That way you don’t leak page rank, and still gain hits from search results from the content of the comments. I may be missing something but this seems to mean that you can have your cake and eat it, and I don’t even think it is gaming the system or against the spirit of it. You might even gain a small sprinkling of page rank if the comment page accumulates any of it’s own.
Secondly, nofollow is also essential on links to off-topic pages, whether they’re internal or external to your site. You want to prevent search engines from misunderstanding what your pages are about. Linking relevant pages together reinforces your topic relevance. So to keep your topic silos clear, strategic use of the nofollow attribute can be applied when linking off-topic pages together.
Pay per click (PPC) advertising, commonly referred to as Search Engine Marketing, delivers targeted traffic and conversions and will yield results faster than organic search engine optimization. Successful PPC marketing programs offer incredible revenue and brand-building opportunities. However, without a thorough understanding of how PPC works, it is very easy to mismanage valuable advertising budgets. That’s where we come in!

Peter made a very good point in all of this, and Michael Martinez did in a backhanded way as well. Talking about a concept related PageRank sounds cool. It doesn’t actually have to be useful or practical, and it usually isn’t; but as long as the impression of something productive is given off, then that can be all that matters in the eyes of those who lack sufficient knowledge.


While ordinary users were not that interested in pages' scores, SEOs of a different caliber felt that this was a great opportunity to make a difference for their customers. This obsession of SEOs with PageRank made everyone feel that this ranking signal is more or less the only important one. In spite of the fact that pages with a lower PR score can beat those with a higher score! What did we receive then, as a result?
