SpeedUp Get It: What is Google Page Rank? How to increase Google Page Rank in websites, Analysis Google Page Rank.
PageRank is what Google uses to determine the importance of a web page. It's one of many factors used to determine which pages appear in search results. PageRank is also sometimes referred to by the slang term "Google juice."
The History of PageRank
PageRank was developed by Google founders Larry Page and Sergey Brin at Stanford. At the time that Page and Brin met, search engines typically linked to pages that had the highest keyword density, which meant people could game the system by repeating the same phrase over and over to attract higher search page results.
What Does PageRank Measure?
PageRank measure's a web page's importance.
Page and Brin's theory is that the most important pages on the Internet are the pages with the most links leading to them. PageRank thinks of links as votes, where a page linking to another page is casting a vote.
This makes sense, because people do tend to link to relevant content, and pages with more links to them are
usually better resources than pages that nobody links.
Google PageRank is a link analysis algorithm used by Google to help determine the relative importance of a website, every website is given a Google PageRank score between 0 and 10 on an exponential scale. The handful of PageRank 10 domains, including USA.gov, Twitter.com and Adobe Reader Download, have the highest volume of inbound links of any sites on the web. The top sites set the bar, so to speak, and the 10-point scale plummets exponentially down from there. Google.com and Facebook.com are PR 9. PageRank 5 websites have a good number of inbound links, PR 3 and 4 sites have a fair amount, and brand new websites without any inbound links pointing to them start at PageRank 0.
Since Google wants to return page one results that are high quality, relevant, and trustworthy, it may return web pages with better PageRank scores higher up in the SERPs, although PageRank is only one of many ranking factors taken into consideration.
Since PageRank is only one factor in the Google ranking algorithm, it’s important to remember that a high PageRank does not guarantee high rankings – but it can significantly help.
Link Juice and PageRank Points
When Site A links to your web page, Google sees this as Site A endorsing, or casting a vote for, your page. Google takes into consideration all of these link votes (i.e., the website’s link profile) to draw conclusions about the relevance and significance of individual web pages and your website as a whole. This is the basic concept behind PageRank.
When a website links to your site, or when you link internally from one of your pages to another, the link passes PageRank points. This passing of PageRank points is also commonly called “ link juice” transfer.
The amount of link juice passed depends on two things: the number of PageRank points of the web page housing the link, and the total number of links on the web page that are passing PageRank. It’s worth noting here that while Google will give every website a public-facing PageRank score that is between 1 and 10, the “points” each page accumulates from the link juice passed by high-value inbound links can – and do – significantly surpass ten. For instance, web pages on the most powerful and significant websites can pass link juice points in the hundreds or thousands. To keep the rating system concise Google uses a lot of math (ask me in the comments if you want to hear about it) to correlate very large (and very small) PageRank values with a neat and clean 1–10 rating scale.
How Link Juice is Passed
Think of it this way: every web page has a limited amount of link juice it can pass, and the top of that limit is the total PageRank points that page has accrued. So, a web page with 20 accrued PageRank points cannot pass more than 20 points of link juice per page. If a page with 20 PageRank points links to one other page, that one link will transfer the full amount of link juice to that one other web page. But if a page with 20 PageRank points links to five web pages (internal or external), each link will only transfer one-fifth of the link juice. Google applies a decay value to every pass, so the actual numbers will be a little less than our diagram shows below. But to explain the PageRank concept simply, the formula is PR points divided by number of on-page links, or in this case, 20 divided by 5:
