Google is apparently testing placing AdWords ads at the bottom of the search results, again. A WebmasterWorld thread has two people reporting seeing this recently.
One said:
I never noticed this before maybe it's not new. I see 3 Adwords Ads on top of the serps as usual and 3 at the bottom directly below the 10th result. There are no Ads at all to the right side of any keywords I check.
Scott added:
Saw this once today. I really wish they'd stop testing.Whatever layout changes they're making impressions for the same spot are down 25% again today. This may explain that.
Google has tested this in the past. Back in 2005 and 2008. Here is a screen shot from 2005:

We've been seeing this in the UK for 2-3 days now. Here are some examples of the current test with no side bar ads. http://twitrpix.com/b5kr http://twitrpix.com/b5kq http://twitrpix.com/b5kw

I find it interesting that you have a search box at the bottom of your results page. I haven't seen a search box for the past two month and it's really irritating me! I like to type in a word and then when I get to the bottom of the list, if I don't like what I see, I refine. I was bummed when I didn't have it any longer.
