Google is a horizontal search engine
; it attempts to index across as much of the Web as possible.
Unlike horizontal search engines
that respond to user queries in the form of links to pages with information, iXiGO Trip Planner attempts to understand user inputs and presents curated travel content summarized in a visual representation of options for modes of transportation, directions and rich information about destinations.
Analysis of advertiser performance data indicates that iXiGO.com has delivered superior return on investment (RoI) to premium advertisers in comparison to horizontal portals and horizontal search engines
Web search engines from Alta Vista to Google, sometimes referred to as horizontal search engines
, exemplify these approaches.
Whether you are a student, a scientist, or a silver surfer, horizontal search engines
are designed from the ground up to deliver the same results to all searchers based on queries and key words.
As the Internet grows and matures, with millions of new sites being posted annually, increased targeted marketing should be the norm and big horizontal search engines
will have to adapt.
