Perhaps an oddity: Adword ad in search results

Found a link from an Adword ad in MSN natural search result

Perhaps it was just a quirk, but for a search term on MSN, I found in the #1 spot a link to my client's site that was a link from an AdWord ad I run. I can clearly see the tracking code in the URL when I clicked on it. My guess is that the MSN spider must have somehow followed an ad link and indexed it. I'm not complaining, just wondering if anyone else found anything like this. I doubt MSN (or Yahoo/Inktomi) and Google are up to anything, especially since it smacks of paid inclusion.

It has taken me a while to digest exactly what you said... As a big spender on Adwords, that surprises me a bit. Have you found any others?

Mind you - if it was a targeted result, I probably wouldn't mind either - if I pay for it through your site, I'd probably pay for it through MSN.

I doubt all Adwords users would see it that way though!

I haven't really looked. I think it was just a case of a spider for some reason following a paid ad link. It was targeted, though, and my client's natural search result was at #7.
