A theme is defined by search engines as a common topic throughout
the site. In an effort to provide their users with more relevant
information, search engines developed sophisticated technology
that "extracts" site's themes. This technology allows
results to be more focused on the topic searched for. Hint:
Think of themes as your most important keywords.
Themes technology is quite complex. It's used by some of the
major search engines when indexing and ranking sites. Currently,
Excite, Altavista, Lycos and Google use themes as part of their
formulas. Inktomi will soon join them. That will include AOL,
Hotbot, iWon, LookSmart, MSN and NBCi.
The purpose of themes is to look at the bigger picture, not
just the parts. To determine a theme spiders index the whole
site and then analyze its HTML. Factors analyzed are: HTML title,
meta tags, headings, text on the site, and links. Spiders use
technologies such as keyword weighting, extrapolation and root
stemming to determine a theme.
