Advertise on this site link in the search results?

how about adding it next to Cached - Similar Pages

Now that my site is on the first page of the results for my top keyword, it'd be great if I could encourage people to advertise right there. Perhaps something like this:
Cached - Similar Pages - Advertise on this site

That's an awesome idea, you should send the suggestion in to Google.

Thanks kilcher

It seems so to me too. I can't think of any real drawbacks to it except perhaps the perception of advertising and search somehow not being as seperate as they should be. But that seems a pretty minor detail which could be explained easily enough.
