You do not pay to get into search engines, and you don’t necessarily need to even submit your site to them, but you do need to know their ‘rules’ – especially rules laid down by Google.
Note; these rules for inclusion can and do change. These rules are official advice from Google, to Webmasters, and Google is really cracking down on ‘low quality’ techniques that influence their rankings in 2012.

Below is a simple monitor to keep track of changes to the top 50 Google Webmaster Guidelines pages and with links to each one* – UPDATE 2 – we’ve also made a quick Pagerank monitor tool, too.
- Cells highlighted Green have been updated in the last month
*If you think there are more important pages let me know, you may be right.
