Just a bit about search engine optimization.

A no follow link is an HTML attribute that is usually giving commands to search engines that the hyperlink is not to influence the ranking of the search engines index. A no follow link is designed to decrease the effectiveness of search engine spam and improve the overall quality of the search engines results.

The idea of the no follow link was developed by Google in 2005 to eradicate spam that may appear in a search when using keywords in search engines. No follow links were not developed to block the access to web content but rather to avoid the content from being indexed by search engines.

Hyperlinks that include the rel=?no follow? attribute will not influence the links target page rank. Although this was a Google design and is copyright owned by Google lots of search engines have began using the attribute value as well such as, Yahoo, Windows Live Search, and Bing.

Rather than not follow the link in a literal since, search engines are supposed to not catalog the link in their databases. The page will remain operable and still load without material being blocked. This is just away to prevent the indexing of spam that appears as a result to the search. Google suggest that the no follow link be enacted in a literal sense where the link will not be followed at all. However, in reports conducted for the SEO different information was discovered. Here it was determined that the links did work but was not indexed to the page it linked to. For Yahoo this means that link will be followed but not taken into consideration in its ranking considerations. MSN Search has yet another variation where the no follow link is neither counted nor followed. The definition of the no follow link will differ from site to site.

Major Weblogs as a routine of submitting links with no follow attribute. There will not be any options to change it as well. Some programs though gives trusted users the options to change. And others may allow the writer to submit the way they write it and later remove the unwanted links to be manually removed.

Many web owners will begin a blog to encourage new content to be displayed on their page and enlarge the overall page rank of the site. The sites page rank can be dropped dramatically if offensive are left on the site so the no follow link allows the bloggers to leave links but protects the webpage owners from taking hits to their page rankings as of them.

The no follow links is used as a machine readable disclosure for the links that have paid for the services by Google. Whether the No Follow link is safeguarding or hurting the web owners is still a dilemma and the owners are pondering over it as many pages are paying for links to be traded. The no follow link is constantly under contradiction by SEO and it totally depends on the web owner to allow or reject them in their site.
