[akasha968]

A vertical search engine may charge more per ad than a general, or "horizontal," search engine. People want relevancy, and the more horizontal search they do, the more they tire of wading through pages of surplus to requirements material.

A vertical search engine as distinct from a general web search engine, focuses on a specific segment of online content. They are also called specialty or topical search engines.
