PageRank (PR) gives the importance of a page on the web. It is named after Larry Page, cofounder of Google. At first it was called Backrub. PageRank is associated only with Google. It is one among the many factors that determines a page’s ranking in the search results. PageRank has an important consideration in SEO.
Google defines PageRank as below (Google Technology)
“PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. Google's PageRank reflects the importance of web pages by considering more than 500 million variables and 2 billion terms. Pages that Google believe are important pages receive a higher PageRank and are more likely to appear at the top of the search results.
PageRank also considers the importance of each page that casts a vote, as votes from some pages are considered to have greater value, thus giving the linked page greater value. We have has always taken a pragmatic approach to help improve search quality and create useful products, and our technology uses the collective intelligence of the web to determine a page's importance."
Thus Google considers backlinks as votes.
According to Google, if one page A gives a link to page B, then page A is casting a vote for page B. If page B gets more number of votes from many different pages then the importance of page B will increase. The quality of the page A which casts the vote determines the quality of the vote.
There are two kinds of Google PageRank. One is Google Toolbar PageRank and the other is Google’s internal PageRank. Internal PageRank is updated every day. But it is not accessible. Toolbar PageRank can be seen by anyone. It is updated around two times a year. So clearly the toolbar shows outdated PageRank.
From my analysis there are a few factors that help to improve your PageRank.
Link Relevancy:
Wikipedia defines Relevance as “In information science and information retrieval, relevance denotes how well a retrieved document or set of documents meets the information need of the user.”
This is the main idea behind every search engine algorithms. When a user types a query on the search box the search engines search the web for pages that contain the search query and tries to return the most relevant results at the top. Thus relevancy means the relationship between two quantities, here the search query and the search results.
To explain link relevancy we can try to answer some questions.
If I get a backlink from a PR 10 website will it improve my rankings?
Yes. But there are some things to be kept in mind. Google can analyze for which text I have given the hyperlink to my site, that means my anchor text. If I have a website for health insurance and I got a backlink from a high PR site with the anchor text “Visit my website” it won’t help in getting any boost in search rankings. I have to use my keywords as anchor text and in here “health insurance”.
Suppose my health insurance website has a PR of 10. Will it come in search results for every search query?
No. This is also because of anchor text. I targeted only for those keywords which people might use to reach my website. For those keywords my site will be the top result.
Now suppose I have a website selling flowers and I got a backlink from a high PR website which sells electronic circuit boards. Do you think it is relevant to get my backlink there?
Google knows that “flowers” is not any way related to “electronic circuit boards”. So regardless of the high PR backlink I got Google considers the relation (Relevance) between the two websites and it finds nothing and my backlink has no value.
As I have explained, Google will try to determine my website’s PageRank based on the high PR sites from where I get backlinks. It can also perform hyperlink text analysis to calculate how relevant my anchor text is. And most importantly how relevant is the page from where I got the backlink and my website.
I think now you have got an idea about Link Relevancy.
Link Quality:
Link quality means get your backlink from quality (high PR) websites. But with relevancy added to link quality we can redefine link quality as
“Getting backlinks using keywords of your website as anchor text from relevant sites with high PageRank”.
Link Quantity:
There is also link quantity to be considered. If your PageRank is 3 and you get backlinks from PR 2 or PR 1 websites it won’t reduce your PageRank. But it will help to optimize your anchor text. Even though backlinks from sites with low PR than your site will not improve your PR, it will help to bring more visitors to your site.
Not every backlink to your page is counted by Google. Google can filter links from link farms. Webmasters cannot control which sites link to their sites. So links coming to my site from a site penalized by Google won’t harm my site. But if I give an outbound link to such a site it may cause Google to penalize my site as well. So be careful in your link building campaign.
If you consider Google PageRank in your SEO campaign it will definitely help you rank better in search results.
