esults. Strangely, Yahoo actually changed the way this worked during the year so that the results from a search were a mix of listings from their own directory and Google with the Google results being the more prominent of the two. This has essentially made the payment of the US$299 per year for a directory listing an unnecessary expense. Many people still use thNews broke this week that Yahoo has purchased the Inktomi search engine for around US$235 million. This is an interesting development in the search engine industry that may impact greatly on exactly where sites get their traffic from. Another new development in the past few weeks is the change to the HotBot service but first, I'd like to look at the ramifications of the Yahoo/Inktomi deal.

Here's a bit of background information on how the Yahoo and Inktomi search engines work. I'm sure everyone knows Yahoo but not everyone may be completely aware of how their search engine works. Yahoo is a directory. This means that it is a categorised list of sites that are listed by human editors. Getting listed in the Yahoo directory requires a yearly payment for commercial sites. You can get listed for free if you have a non-commercial site but it is very hard to do and can take months. Yahoo provides additional results when you use their search function that come from Google. In the past, Yahoo has used other search engines to provide these results (including Inktomi) but has used Google for the last couple of years.

They initially used results from other search engines to just compliment their own. So, if someone searched for something that wasn't in their directory, they could still get results. The way it worked was that they would provide results from their own directory first and then a user would click on "web pages" to get more results.

This has essentially made the payment of the US$299 per year for a directory listing an unnecessary expense. Many people still use the directory to browse for sites but, in my experience, more people use the search function.

Inktomi is a full crawler based search engine that provides results for other search engines. They do have a web site but no-one uses it to actually search - it's more of an informational site. Inktomi's results formerly appeared in many search engines but in the last few years, their popularity has declined. The main site that currently uses Inktomi is MSN but Inktomi only provides the fifth level of results. MSN provides sponsored listings from Overture, their own Microsoft sites, their own human edited directory results, LookSmart listings and then Inktomi. So, Inktomi does drive traffic to sites but far less than a search engine like Google.

So, what does all this mean to us? It's hard to say at the moment but there are three options. Either nothing will change (which is unlikely), Yahoo will use Inktomi together with Google on it's site or it will dump Google and use Inktomi for it's search results. Yahoo actually owns part of Google, maybe 5%, so there is a chance that they will keep using their results for this reason. Also, Google provide far better results for searchers than Inktomi so Yahoo would be making a mistake to replace Google. But, apparently Yahoo is annoyed that Google has become competition to them through Google's own site and that Google's news search service is also providing competition.
