Inktomi

Inktomi's popularity grew several years ago as they powered
the secondary search database that had driven Yahoo. Since
then, Yahoo as switched to using Google as their secondary
search and backend database, however Inktomi is just as
popular now, as they were several years ago, if not more so.
Their spiders are named "Slurp", and different versions of
Slurp crawls the web many different times throughout the
month, as Inktomi powers many sites search results. There
isn't much more to Inktomi then that. Slurp puts heavy
weight on Title and description tags, and will rarely deep
crawl a site. Slurp usually only spider’s pages that are
submitted to its index.

Inktomi provides results to a number of sites. Some of these
are America Online, MSN, Hotbot, Looksmart, About, Goto,
CNet, Geocities, NBCi, ICQ and many more.
