3 SEO links to Optimise the Web Site

I found 3 immense SEO friendly tools and those are listing a site on the search tools of Google, Yahoo and MSN. One has to just click on the below given links and one will be directed to the main site where one can fill details regarding the site. One may have to authenticate a site by adding a meta tag in the head portion of the site and one is all ready to rank high for the search engine rankings.
URL: www.google.com/webmasters/tools/
URL: webmaster.live.com/webmaster
URL: siteexplorer.search.yahoo.com

2. One can even use the http://advertising.microsoft.com/search-advertising/adcenter_addin for the keyword research tool of MSN.
