Deep linking is hyperlinking to a section of a website
By creating a deeplink, a user is immediately directed to the right content (instead of To a meaningless home page). Search engines use deep links to determine the quality of a website (quality score), if there are many deep links, then it is an interesting site than the reasoning. A deeplink to this page is: http://www.wat-betekent.nl/wat-is-deeplinking/. In the past, there have been lawsuits to deep linking, because news sites In particular were not happy with the fact that people directly linked to an article (which caused them to miss a lot of ad revenues on the home page). Therefore, it is not allowed in all countries either.
