Mathematical PageRanks for a simple network, expressed as percentages. (Google uses a logarithmic scale.) Page C has a higher PageRank than Page E, even though there are fewer links to C; the one link to C comes from an important page and hence is of high value. If web surfers who start on a random page have an 85% likelihood of choosing a random link from the page they are currently visiting, and a 15% likelihood of jumping to a page chosen at random from the entire web, they will reach Page E 8.1% of the time. (The 15% likelihood of jumping to an arbitrary page corresponds to a damping factor of 85%.) Without damping, all web surfers would eventually end up on Pages A, B, or C, and all other pages would have PageRank zero. In the presence of damping, Page A effectively links to all pages in the web, even though it has no outgoing links of its own.
Search engine optimization (SEO) is the process of improving the visibility of a website or webpage on a search engine results page (SERP) so as to make a company’s website more discoverable (i.e., on the first page/s), thereby driving traffic and sales. Tedious, involving technical and business decisions, and not guaranteeing results—it nonetheless provides lasting benefits.

PageRank has been used to rank public spaces or streets, predicting traffic flow and human movement in these areas. The algorithm is run over a graph which contains intersections connected by roads, where the PageRank score reflects the tendency of people to park, or end their journey, on each street. This is described in more detail in "Self-organized Natural Roads for Predicting Traffic Flow: A Sensitivity Study".


If you’re just getting started with SEO, you’re likely to hear a lot about “backlinks,” “external and internal links,” or “link building.” After all, backlinks are an important SEO ranking factor for SEO success, but as a newbie, you may be wondering: what are backlinks? SEO changes all the time — do backlinks still matter? Well, wonder no more. Say hello to your definitive guide to backlinks and their significance in SEO.
I agree that the more facts that you provide and if you were to provide the complete algorithm, people would abuse it but if it were available to everyone, would it not almost force people to implement better site building and navigation policies and white hat seo simply because everyone would have the same tools to work with and an absolute standard to adhere to.

More appropriately, blame Google for ever making the PageRank score visible. When Google first started, PageRank was something it talked about as part of its research papers, press releases and technology pages to promote itself as a smarter search engine than well-established and bigger rivals at the time — players like Yahoo, AltaVista and Lycos, to name a few.
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.
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.
I first discovered Sharpe years ago online. His story was one of the most sincere and intriguing tales that any one individual could convey. It was real. It was heartfelt. It was passionate. And it was a story of rockbottom failure. It encompassed a journey that mentally, emotionally and spiritually crippled him in the early years of his life. As someone who left home at the age of 14, had a child at 16, became addicted to heroin at 20 and clean four long years later, the cards were definitely stacked up against him.
When you comment on a blog post, you are usually allowed to include a link back to your website. This is often abused by spammers and can become a negative link building tool. But if you post genuine comments on high-quality blog posts, there can be some value in sharing links, as it can drive traffic to your site and increase the visibility of your brand.
If you’re new to internet marketing and wish to get online as quickly and inexpensively as possible you can start with a social media platform like Facebook - you can create a business Facebook page in less than an hour. However, if you want more control over your online presence, a customized website is more appropriate. Ideally you should have both a website and a social media presence, with each linking to the other.
As Rogers pointed out in his classic paper on PageRank, the biggest takeaway for us about the eigenvector piece is that it’s a type of math that let’s you work with multiple moving parts. “We can go ahead and calculate a page’s PageRank without knowing the final value of the PR of the other pages. That seems strange but, basically, each time we run the calculation we’re getting a closer estimate of the final value. So all we need to do is remember the each value we calculate and repeat the calculations lots of times until the numbers stop changing much.”
Keeping up with the latest trends is a must for any business, but ignoring technology trends in the digital world is the matter of staying in business. Unfortunately, those trends (while easy enough to find mentioned online) are rarely explained well. There seems to be this mistaken idea that anyone who has an interest or need in the practice will just magically get the jargon. As we all know, that is one superpower that doesn’t exist in the real world.
I find it amazing that youtube.com has been “nofollowing” its featured videos for last 12 months (still doing it as I type) when it now seems that this means “i dont trust this content” and “i want to page rank to flow to this content”. In fact a quick glance at a youtube page tells you that youtube are currently flushing 50% of their page rank (very approx) down the toilet on every page.
Advertising with Google won't have any effect on your site's presence in our search results. Google never accepts money to include or rank sites in our search results, and it costs nothing to appear in our organic search results. Free resources such as Search Console, the official Webmaster Central blog, and our discussion forum can provide you with a great deal of information about how to optimize your site for organic search.

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.
PageRank sculpting came out of the idea that virtually any page will have links that are important for users but not necessarily that meaningful to receive any PageRank that a page can flow. Navigational links are a primary example of this. Go to a place like the LA Times, and you’ve got tons of navigational links on every page. Nofollow those, and you (supposedly in the past) ensure that the remaining links (say your major stories) get more of a boost.
To create an effective DMP, a business first needs to review the marketplace and set 'SMART' (Specific, Measurable, Actionable, Relevant and Time-Bound) objectives.[60] They can set SMART objectives by reviewing the current benchmarks and key performance indicators (KPIs) of the company and competitors. It is pertinent that the analytics used for the KPIs be customised to the type, objectives, mission and vision of the company.[61][62]

Due to the importance of backlinks, there are lots of bad practices followed by website owners to gain backlinks. Some of these bad practices are: purchasing backlinks, link exchange networks, selling backlinks, etc. Most of these practices are not recommended by search engines. They usually deindex and penalize websites suspected of involvement in such practices.
The Nielsen Global Connected Commerce Survey conducted interviews in 26 countries to observe how consumers are using the Internet to make shopping decisions in stores and online. Online shoppers are increasingly looking to purchase internationally, with over 50% in the study who purchased online in the last six months stating they bought from an overseas retailer.[23]
Gaining Google's trust doesn't happen overnight. It takes time. Think about building up your relationship with anyone. The longer you know that person, the more likely that trust will solidify. So, the reasoning is, that if Google just met you, it's going to have a hard time trusting you. If you want Google to trust you, you have to get other people that Google already trusts, to vouch for you. This is also known as link-building.
Backlinks can be time-consuming to earn. New sites or those expanding their keyword footprint may find it difficult to know where to start when it comes to link building. That's where competitive backlink research comes in: By examining the backlink profile (the collection of pages and domains linking to a website) to a competitor that's already ranking well for your target keywords, you can gain insight about the link building that may have helped them. A tool like Link Explorer can help uncover these links so you can and target those domains in your own link building campaigns.
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.

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.
My favorite tool to spy on my competitors' backlinks is called Monitor Backlinks. It allows you to add your four most important competitors. From then on, you get a weekly report containing all the new links they have earned. Inside the tool, you get more insights about these links and can sort them by their value and other SEO metrics. A useful feature is that all the links my own website already has are highlighted in green, as in the screenshot below.

Data science is the core of every campaign we build and every goal we collectively set with clients.
Ask for a technical and search audit for your site to learn what they think needs to be done, why, and what the expected outcome should be. You'll probably have to pay for this. You will probably have to give them read-only access to your site on Search Console. (At this stage, don't grant them write access.) Your prospective SEO should be able to give you realistic estimates of improvement, and an estimate of the work involved. If they guarantee you that their changes will give you first place in search results, find someone else.
Internet usage around the world, especially in the wealthiest countries, has steadily risen over the past decade and it shows no signs of slowing. According to a report by the Internet trend investment firm Kleiner Perkins Caulfield & Byers, 245 million people in the United States were online as of 2011, and 15 million people connected for the first time that year. As Internet usage grows, online commerce grows with it. This means that more people are using the Internet with each passing year, and enough of them are spending money online to impact the economy in significant ways. (See also E-Commerce Marketing)
The mathematics of PageRank are entirely general and apply to any graph or network in any domain. Thus, PageRank is now regularly used in bibliometrics, social and information network analysis, and for link prediction and recommendation. It's even used for systems analysis of road networks, as well as biology, chemistry, neuroscience, and physics.[45]

In my view there is nothing wrong with saying ‘hey Google, these pages are not important from a search engine perspective, let me not give them so much weight’. Regardless of how Google now views these type of pages from a weight perspective, doing the above as a webmaster should be logical and encouraged. You have said this yourself at least a few times in the past.
