nofollowregler

Nofollowregler refers to a set of guidelines used by search engines to determine when to ignore or not follow a particular hyperlink. The primary purpose of these guidelines is to prevent spam and maintain the integrity of search results.

Introduced in 2005 by Google, the nofollow attribute is a value added to an HTML link tag to tell search engines not to follow the link. This allows web developers and publishers to prevent spiders from linking to certain websites, such as paid links or low-quality content.

When a link on a webpage carries the nofollow attribute, search engines treat it as having less authority regarding the target webpage's content. As a result, the link's "link juice" is either partially or completely preserved, rather than being passed on entirely to the target webpage. This means that any ranking boost the original webpage might have received is either toned down or eliminated.

In addition to its anti-spam goals, the nofollow attribute helps maintain the trust and credibility of search results. Online entities that engage in practices involving low-quality content, for instance, may be assigned nofollow links. This indicates that their methods go against the principles of producing valuable, reliable, and relevant content.

By using the nofollowregler, online publishers and developers can more effectively limit their responsibility for their links to certain sites.
