Understanding Search Engines
•Some search engine operators sell paid placement rights
on results pages. These paid placement links are often labeled
as “sponsored,” and they are
usually called sponsored
links.
•If the advertising appears in a box on the page (usually
at the top, but sometimes along
the side or bottom of the page), it is usually called a banner ad.
•Revenue from sponsored links and banner ads is used to generate
profit after covering the costs of maintaining the computer hardware and software required to search the
Web and to create and search
the database.
