AltaVista

Many who have access to web logs may have seen a spider
named 'scooter' accessing their pages. Scooter used to be
AltaVista's robot. However, since the Feb 2001 site update,
a newer form of Scooter is now crawling the web. Whichever
spider AltaVista uses, it is one of the largest search
engines on the net today, next to Google.

It will usually take several months for AltaVista to index
your entire site, although the past few months scooter
hasn't been deep crawling too well. Unlike Google, AltaVista
will only crawl and index 1 link deep, so it takes a good
amount of time to index your site depending on how large
your site is.

AltaVista gets most of its results from its own index,
however they do pull the top 5 results of each search from
Overture (formerly Goto).
