Abstract: Mobile friendly internet searches are enabled by determining if individual internet sites are mobile friendly. In a described implementation, a mobile-friendliness indication is determined for an internet site. The determined mobile-friendliness indication is stored in association with the internet site in an index that may be used for internet searching. In another described implementation, a data structure comprises an internet index with multiple internet site entries having one or more associated mobile-friendliness indications. The mobile-friendliness indications may be general affirmative indications of mobile friendliness or specific indications of mobile-friendliness that identify a specific user agent type. In yet another described implementation, a search request having search terms is received, and a search is performed based thereon to produce a search results set.
