PageRank is the heart of the software that runs Google. Itís a system for ranking webpages developed by Google founders, Larry Page and Sergey Brin.
PageRank relies on the nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of links a page receives. It also analyzes the page that links to the linked page. Links from pages that are themselves "important" weigh more heavily and help to make other pages "important."
Important, high-quality sites receive a higher PageRank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don't match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page's content (and the content of the pages linking to it) to determine if it's a good match for a search query.
So always try to get links from webpages with a PageRank of 3 and above. Anything lower is generally a waste of time.
But what is also important is the number of links out of the page that youíre receiving a link from. Itís almost definitely more beneficial to get a link from a webpage with a PageRank of 4 that only contains a few external links, than one from a page with a higher PageRank, but contains hundreds of outgoing links.
The reason is because every outgoing link has a share of the PageRank that a page offers. So the more outgoing links there are, the less PageRank each link gets.
Lastly, concentrate on getting as many different quality sites as possible to link to one page on your site, usually your home page. Do not spread the links to different pages. This will maximize the PageRank of your main page, plus those of the subpages.
Here are what I believe to be the two most important ranking factors used by Google. My findings are as a result of my ongoing optimization experiments of my network of websites on Google.
The top two Google ranking factors are:
Iíve explained what PageRank is above and why its importance in getting higher search engine rankings. Add incoming text links keywords and you have the formula for high search engine rankings.
Always provide text links for linking to your site. Avoid image links.
Google does index image links, but without any text for it to index, it won't help your link popularity rating for your important keywords.
Well, there you have it. Those are what I consider the two most important ranking factors used by Google. Other factors are considered by Google, but their importance pales in comparison to the two discussed here.
Follow these tips whenever you optimize your webpages and they will quickly shoot up the Google rankings.
