How Search Engines Use NoFollow

Search engines each interpret NoFollow in their own way. Here's a list of the major search engines, and their actions when a NoFollow link is seen:

* Google follows NoFollow links but simply does not pass on credit to an outbound link that is tagged with the attribute.
* Yahoo follows NoFollow links and excludes the link from all ranking calculations.
* MSN may or may not follow a NoFollow link, but it does exclude it from ranking calculations.
* Ask.com does not adhere to NoFollow.
