Inktomi http://www.inktomi.com/
is a search engine that does not offer its search services through its
own site, but through Partner sites – prominent ones being MSN Search,
AOL Search, HotBot and others. Inktomi, through its crawler, creates
three different indexes. "Best of the Web” index has around 110 million
pages that it indexes on the web and considers high in link analysis.
The next set of around 390 million pages is indexed as "Rest of the
Web”, considered as lower in link analysis. The third index is of paid
inclusion. It also offers specialized regional indexes as well as
targeted news, multimedia and directory indexes. It avoids duplication
of the same page in more than one index. Link crawling and paid
inclusion are the two most effective ways to get covered by crawling.
For bulk submissions to its paid program, it offers IndexConnect (for
1000 or more pages). Again, there is a cost-per-click basis with a
monthly minimum. Ranking at Inktomi is determined by a combination of
factors including HTML links, keywords and description tags near the top
of the page or in the title tag. If the search string matches with what
is found at these places on the page, the ranking is higher. Link
analysis and analysis of clickthroughs are other important criteria that
it adopts.
