PageRank is a way of measuring the importance of website pages. According to Google: PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites. [1]
The History of Google Page Rank. PageRank was developed by Larry Page and Sergey Brin, the founders of Google, while they were Ph.D. students at Stanford University in the late 1990s. The idea behind PageRank is seemingly simple: it ranks web pages based on their importance, as determined by the number and quality of links to them.

Over the years, there have been a lot of different ways SEOs have abused the system in the search for more PageRank and better rankings. Google has a whole list of link schemesthat include: 1.

On January 18, 2005, Google announced it had partnered with other major search engines to introduce the rel=“nofollow” attribute. It encouraged users to add the nofollowattribute to blog comments, trackbacks, and referrer lists to help combat spam. Here’s an excerpt from Google’s official statement on the introduction of nofollow: Almost all modern...
As SEOs found new ways to game links, Google worked on new algorithms to detect this spam. When the original Penguin algorithm launched on April 24, 2012, it hurt a lot of websites and website owners. Google gave site owners a way to recover later that year by introducing the disavow tool on October 16, 2012. When Penguin 4.0launched on September 2...
Rather than splitting the PageRank equally between all links on a page, some links are valued more than others. There’s speculation from patents that Google switched from a random surfer model (where a user may go to any link) to a reasonable surfer model(where some links are more likely to be clicked than others so they carry more weight).
There have been several systems put in place to ignore the value of certain links. We’ve already talked about a few of them, including: 1. Nofollow, UGC, and sponsored attributes. 2. Google’s Penguin algorithm. 3. The disavow tool. 4. Link Spam updates. Google also won’t count any links on pages that are blocked by robots.txt. It won’t be able to c...
Google has a canonicalizationsystem that helps it determine what version of a page should be indexed and to consolidate signals from duplicate pages to that main version. Canonical link elementswere introduced on February 12, 2009, and allow users to specify their preferred version. Redirects were originally said to pass the same amount of PageRank...
When pages are marked as noindex, we don’t exactly know how Google treats the links. Even Googlers have conflicting statements. According to John Mueller, pages that are marked noindex will eventually be treated as noindex, nofollow. This means that the links eventually stop passing any value. According to Gary, Googlebot will discover and follow t...
Redirecting old pages on your site to relevant new pages can help reclaim and consolidate signals like PageRank. Websites change over time, and people don’t seem to like to implement proper redirects. This may be the easiest win, since those links already point to you but currently don’t count for you. Here’s how to find those opportunities: 1. Pas...
Backlinks aren’t always within your control. People can link to any page on your site they choose, and they can use whatever anchor text they like. Internal links are different. You have full control over them. Internally link where it makes sense. For instance, you may want to link more to pages that are more important to you. We have a tool withi...
