Yes, but they used to use Overture at the bottom of the page (in the drop down boxes). There were also Espotting, Dealtime and Directhit in those boxes, with some others. Espotting and Directhit are still there.
Surprisingly, the bottom boxes of Ask.co.uk gave me more visitors than anything else other than Google, MSN and Dealtime. Which is wierd, because I don't rank badly on Fast/Lycos and I would have thought that would have pulled more.
The main point I was making is that ask.co.uk and .com have both dropped Overture. The UK is often very different from the .com sites. For example, loads of people got excited about yahoo.com displaying Overture listings. Not on the .co.uk site, you get Espotting.
It is interesting that the UK version of AskJeeves have dropped Overture. Is there the possibility of them showing Google Adwords also?
