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.

Most of the search engines use formulas similar to pagerank that uses external and internal links as main inputs to determine the importance of specific documents and their ranking in results.

Basically, the great increase in number of external links over a certain level is causing the loss of importance of the site in favour of those sites that are being linked.

Every webmaster should consider which sites are important and worth linking. A rapid growth in the number of external links indicates possible problems with people that abuse, for example guestbooks on domain to submit their links, or even possible cross site scripting abuse and so on...

Every responsible webmaster should know the actual number of pages (unique documents) of the domain. As soon as your indexed pages exceed the number of actual unique documents, you will know for sure that you have duplicate content in the search engine index. Search engines tend to penalize sites with duplicate content, because they are simply draining their resources for no reason.

Why is this information so valuable?

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.
