PageRank and comments relationship
SEO | August 12, 2010
Search engines as Google, Bing and Yahoo all have a list of search engine algorithms that determine the rankings of the different web pages in the list that is presented when doing a search. These algorithms are based on a system of positive and negative weights or ranking factors. One of these factors is the well known (in the SEO world) Google's PageRank algorithm.
PageRank or PR, is a measurement of how important some web page is. This scale goes from 1 to 10, with 10 being the most popular or important web page (currently only google.com, facebook.com and twitter.com have 9).
Below is an image to explain the PageRank and its relation with inbound linking.
Above are four web pages, the top-left one has inbound links that help it to get 100 popularity points. Additionally this page has two outbound links to the right pages. These links distribute the popularity of the top-left page among the right ones, each one receiving 50 points. Notice too, that the top-right page receives 3 points from the bottom-left page.
After this short explanation it can be noticed that two key factors arise: the number of inbound links and the quality of those links. For example a web page may have tons of links but if them do not come from important pages then another page with a few very important links will have a higher PageRank.
Nonetheless it is vitally important to get inbound links. The best way to do this is to have the most interesting content, so that links will come naturally. However there are a few actions you can take to gain inbound links.
One of these is to comment everything you read. On most web pages there is a nice comment form waiting for you to write an original opinion about the content just read. This comment form usually has a website box to fill with the url of your site. Then after the comment is posted there should be a link to your site.
Sometimes we feel fear about expressing our ideas, thinking that maybe it is not a good one, or maybe that it is not correct. Well, do not think this way, just feel free to write whatever you think about the post. Maybe your base idea is wrong, but what a heck, someone following this advice will tell you that, and you'll be gaining more knowledge in the long run. Furthermore you'll have a link to your site, which is a vote for you =)
Take in count too, that you will be generating extra content for the post owner and he will be grateful for that.
