Techniques are provided for generating quality measures for items, including web pages, based on a 'random searcher' behavior model. The random searcher behavior model takes into account 'implicit' links between items, instead of or in addition to the explicit links. After identifying the implicit links between items, the implicit links may be used as the basis for generating quality measures for the items to which the implicit links point. A variety of types of implicit links are described. To facilitate the generation of quality measures for items based on implicit links, a graph of the implicit links may be constructed in a manner similar to a webgraph.

Determining quality measures for web objects based on searcher behavior

A system and method are disclosed for identifying a keyword that is a novel concept or anomaly based on prior search results for the keyword. Advertisements may be sold for the keyword, or the keyword may be purchased or recommended for purchase based on anticipation of increased future searches on the keyword.
