Well, in todays post lets see how Google ranks one webpage. The answer to this question is PageRank and Hypertext-matching analysis !!
I know you might be staring at this word. Yes Google uses a very efficient algorithm to rank our page . Even though Google didn't reveal their page ranking algorithm (Ofcourse they won't !!) we will get a small idea about their algorithm from their company pages.
In Google's PageRank they checks the entire link structure of the web and determine which all pages are important. Next they perform a hypertext-matching analysis to find which pages are relevant to the specific search being conducted !!
Inorder to get good PageRank, you need to get good links from related sites which points to your site. The more links point to your web site, the better your rankings. One thing about the quality of links its better to have a link that contains the keyword other than having 'click here' on the links.
Now hypertext matching analysis. Google, instead of simply scanning for meta-tags they analyze the full content of a page and factors in fonts, subdivisions and the precise location of each word.
Now, I hope you people got some idea about PageRank !!
