Why is this information so valuable?

Search engines love valid HTML documents because of the simple reason that "it makes their job easier". For example if you don’t close some tags or if you simply don’t deliver HTML in orderly fashion, it makes the parsing process of your HTML document harder, which draws additional resources from the search engine.

Therefore, search engines tend to favour documents that contain 100% valid HTML. If you want to get detailed information on where you made any mistakes, you should search for open source validators that are able to display these errors within the HTML code. The fact that your website is correctly displayed in your browser does not necessarily mean that your HTML documents are 100% correct.

Sites linking to your site are basically "voting" for your site to be higher in ranking in the same way one votes for a candidate in democratic elections.

The more votes the candidate gets, the higher the chance is that he will win the elections. Search engines pay special attention to this ranking factor and every webmaster who relies on search engine traffic should do the same. Basically, backlinks are one of the most important factors that influence the position of your site in search engine results.

If pagerank of anyweb.com is for example 4 it means that it is 2 times more powerful than Pagerank 3 and 2 times less powerful thank pagerank 5.
