MSN has applied an update to its search algorithm that seems to have significantly affected search results. The update was uncovered when a group of users from Webmaster World forums noticed a change in their backlink counts.
Windows Live Search and other search engines frequently update their algorithms to remove online spam and increase the quality of the results. Webmaster World forum users have reported a reduction in online SPAM blogs, while Ross Dunn has noticed the removal of some Adwords landing pages.
