SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO.[49] White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.[50]

If you own, manage, monetize, or promote online content via Google Search, this guide is meant for you. You might be the owner of a growing and thriving business, the webmaster of a dozen sites, the SEO specialist in a Web agency or a DIY SEO ninja passionate about the mechanics of Search : this guide is meant for you. If you're interested in having a complete overview of the basics of SEO according to our best practices, you are indeed in the right place. This guide won't provide any secrets that'll automatically rank your site first in Google (sorry!), but following the best practices outlined below will hopefully make it easier for search engines to crawl, index and understand your content.

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.


Targeting, viewability, brand safety and invalid traffic: Targeting, viewability, brand safety and invalid traffic all are aspects used by marketers to help advocate digital advertising. Cookies are a form of digital advertising, which are tracking tools within desktop devices; causing difficulty, with shortcomings including deletion by web browsers, the inability to sort between multiple users of a device, inaccurate estimates for unique visitors, overstating reach, understanding frequency, problems with ad servers, which cannot distinguish between when cookies have been deleted and when consumers have not previously been exposed to an ad. Due to the inaccuracies influenced by cookies, demographics in the target market are low and vary (Whiteside, 2016).[42] Another element, which is affected within digital marketing, is ‘viewabilty’ or whether the ad was actually seen by the consumer. Many ads are not seen by a consumer and may never reach the right demographic segment. Brand safety is another issue of whether or not the ad was produced in the context of being unethical or having offensive content. Recognizing fraud when an ad is exposed is another challenge marketers face. This relates to invalid traffic as premium sites are more effective at detecting fraudulent traffic, although non-premium sites are more so the problem (Whiteside, 2016).[42]
SEO is a marketing discipline focused on growing visibility in organic (non-paid) search engine results. SEO encompasses both the technical and creative elements required to improve rankings, drive traffic, and increase awareness in search engines. There are many aspects to SEO, from the words on your page to the way other sites link to you on the web. Sometimes SEO is simply a matter of making sure your site is structured in a way that search engines understand.
Just because some people have been turning their page, way to, pink (with the Firefox ‘nofollow’ indicator plug in installed) that is not a reason to devalue something that is OK to do. It would not of been that hard to plug in a change that would pick that up as spam and therefore put a ‘trust’ question mark against sites that have been ‘nofollowing’ everything.
The SEO starter guide describes much of what your SEO will do for you. Although you don't need to know this guide well yourself if you're hiring a professional to do the work for you, it is useful to be familiar with these techniques, so that you can be aware if an SEO wants to use a technique that is not recommended or, worse, strongly discouraged.
After finding websites that have good metrics, you have to make sure the website is related to your site. For each competitor backlink, try to understand how your competitor got that link. If it was a guest article, send a request to become a contributor as well. If it was a product review by a blogger, contact the writer and offer them a good deal in exchange for a similar review.
[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. 

Search engines may penalize sites they discover using black hat methods, either by reducing their rankings or eliminating their listings from their databases altogether. Such penalties can be applied either automatically by the search engines' algorithms, or by a manual site review. One example was the February 2006 Google removal of both BMW Germany and Ricoh Germany for use of deceptive practices.[53] Both companies, however, quickly apologized, fixed the offending pages, and were restored to Google's list.[54]
Google's founders, in their original paper,[18] reported that the PageRank algorithm for a network consisting of 322 million links (in-edges and out-edges) converges to within a tolerable limit in 52 iterations. The convergence in a network of half the above size took approximately 45 iterations. Through this data, they concluded the algorithm can be scaled very well and that the scaling factor for extremely large networks would be roughly linear in {\displaystyle \log n} , where n is the size of the network.
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.
Display advertising - As the term infers, Online Display Advertisement deals with showcasing promotional messages or ideas to the consumer on the internet. This includes a wide range of advertisements like advertising blogs, networks, interstitial ads, contextual data, ads on the search engines, classified or dynamic advertisement etc. The method can target specific audience tuning in from different types of locals to view a particular advertisement, the variations can be found as the most productive element of this method.

Google will index this link and see that ESPN has a high authority, and there is a lot of trust in that website, but the relevancy is fairly low. After all, you are a local plumber and they are the biggest sports news website in the world. Once it has indexed your website, it can see that they do not have a lot in common. Now, Google will definitely give you credit for the link, but there is no telling how much.
Mega-sites, like http://news.bbc.co.uk have tens or hundreds of editors writing new content – i.e. new pages - all day long! Each one of those pages has rich, worthwile content of its own and a link back to its parent or the home page! That’s why the Home page Toolbar PR of these sites is 9/10 and the rest of us just get pushed lower and lower by comparison…

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.
One common scam is the creation of "shadow" domains that funnel users to a site by using deceptive redirects. These shadow domains often will be owned by the SEO who claims to be working on a client's behalf. However, if the relationship sours, the SEO may point the domain to a different site, or even to a competitor's domain. If that happens, the client has paid to develop a competing site owned entirely by the SEO.
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.

Backlink is a link one website gets from another website. Backlinks make a huge impact on a website’s prominence in search engine results. This is why they are considered very useful for improving a website’s SEO ranking. Search engines calculate rankings using multiple factors to display search results. No one knows for sure how much weight search engines give to backlinks when listing results, however what we do know for certain is that they are very important.


Matt, this is an excellent summary. I finally got around to reading “The Search” by John Battelle and it was very enlightening to understand much of the academia behind what led to the creation of Backrub.. er Google.Looking at how many times the project was almost shutdown due to bandwidth consumption (> 50% of what the university could offer at times) as well as webmasters being concerned that their pages would be stolen and recreated. It’s so interesting to see that issues we see today are some of the same ones that Larry and Sergey were dealing with back then. As always, thanks for the great read Matt!
This pagerank theme is getting understood in simplistic ways, people are still concerning about pagerank all the time (talking about SEOs). I just use common sense, if I were the designer of a search engine, besides of using the regular structure of analysis, I would use artificial intelligence to determine many factors of the analysis. I think this is not just a matter of dividing by 10, is far more complex. I might be wrong, but I believe the use of the nofollow attribute is not a final decision of the website owner any more is more like an option given to the bot, either to accept or reject the link as valid vote. Perhaps regular links are not final decision of the webmaster too. I think Google is seeing websites human would do, the pages are not analyzed like a parser will do, I believe is more like a neural network, bit more complex. I believe this change make a little difference. People should stop worrying about pagerank and start building good content, the algorithm is far more complex to determine what is next step to reach top ten at Google. However nothing is impossible.
While most search engine companies try to keep their processes a secret, their criteria for high spots on SERPs isn't a complete mystery. Search engines are successful only if they provide a user links to the best Web sites related to the user's search terms. If your site is the best skydiving resource on the Web, it benefits search engines to list the site high up on their SERPs. You just have to find a way to show search engines that your site belongs at the top of the heap. That's where search engine optimization (SEO) comes in -- it's a collection of techniques a webmaster can use to improve his or her site's SERP position.
Just do a quick Google search. If you're monitoring to see if a link you built is indexed, or just want to find other areas where you've been mentioned or linked, do a quick search with your company brand name, your web URL or other terms you're following. I've seen plenty of backlinks indexed by the search engine that never showed up in my search console account.
The first component of Google's trust has to do with age. Age is more than a number. But it's not just the age when you first registered your website. The indexed age has to do with two factors: i) the date that Google originally found your website, and; ii) what happened between the time that Google found your website and the present moment in time.

When Googlebot crawls a page, it should see the page the same way an average user does15. For optimal rendering and indexing, always allow Googlebot access to the JavaScript, CSS, and image files used by your website. If your site's robots.txt file disallows crawling of these assets, it directly harms how well our algorithms render and index your content. This can result in suboptimal rankings.

PageRank has been used to rank spaces or streets to predict how many people (pedestrians or vehicles) come to the individual spaces or streets.[51][52] In lexical semantics it has been used to perform Word Sense Disambiguation,[53] Semantic similarity,[54] and also to automatically rank WordNet synsets according to how strongly they possess a given semantic property, such as positivity or negativity.[55]
In both versions of my model, I used the total of my initia esitimate to check my math was not doing south. After every iteration, the total Pagerank remains the same. This means that PageRank doesn’t leak! 301 redirects cannot just bleed PageRank, otherwise the algorithm might not remain stable. On a similar note, pages with zero outbound links can’t be “fixed” by dividing by something other than zero. They do need to be fixed, but not by diluing the overall PageRank. I can maybe look at these cases in more depth if there is some demand.

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).

A breadcrumb is a row of internal links at the top or bottom of the page that allows visitors to quickly navigate back to a previous section or the root page. Many breadcrumbs have the most general page (usually the root page) as the first, leftmost link and list the more specific sections out to the right. We recommend using breadcrumb structured data markup28 when showing breadcrumbs.


This will help you replicate their best backlinks and better understand what methods they are using to promote their website. If they are getting links through guest blogging, try to become a guest author on the same websites. If most of their links come from blog reviews, get in touch with those bloggers and offer them a trial to test your tool. Eventually, they might write a review about it.
The green ratings bars are a measure of the importance Google’s assessment of the importance of a web page, as determined by Google’s patented PageRank technology and other factors. These PageRank bars tell you at a glance whether other people on the web consider Google considers a page to be a high-quality site worth checking out. Google itself does not evaluate or endorse websites. Rather, we measure what others on the web feel is important enough to deserve a link. And because Google does not accept payment for placement within our results, the information you see when you conduct a search is based on totally objective criteria.
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.
[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 will like your content if your clients like it. The content should be helpful and contain less information which is already known to the reader. It is to meet their expectations. When users vote for your site, it means that Google starts accepting it as an authority site. That’s why content writing is as important as a speech of a candidate for the Presidency. The better it is, the more visitors you have.
