I was just checking my logs and I saw a referral from a big music magazine. I checked the page and there is a link to my site in the Overture sponsored results.
Only thing is I don't use PPC and have no Overture account. My first thought was they are infilling with results from their SERPS but my page isn't anywhere to be seen in a search for that particular band.
I know what you mean - but this goes to a page that just lists tour dates for a famous band. Given the choice, I'm sure the band would link to their own tour page or a ticket site.
Thinking about infill, maybe they take results from Ask rather than Yahoo. That might make sense.
