Classifications of Search Engines (Secondary search engines)

Secondary search engines are targeted at smaller, more specific audiences, although the search engine’s
content itself is still general. They don’t generate as much traffic as the primary search engines, but
they’re useful for regional and more narrowly focused searches. Examples of secondary search engines
include Lycos, LookSmart, Miva, Ask.com, and Espotting.
Secondary search engines, just like the primary ones, will vary in the way they rank search results.
Some will rely more heavily upon keywords, whereas others will rely on reciprocal links. Still others
might rely on criteria such as meta tags or some proprietary criteria.
Secondary search engines should be included in any SEO plan. Though these search engines might
not generate as much traffic as the primary search engines, they will still generate valuable traffic
that should not be overlooked. Many users of secondary search engines are users because they have
some loyalty to that specific search engine. For example, many past AOL users who have moved on
to broadband Internet service providers still use the AOL search engine whenever possible, because
it’s comfortable for them.
