Who supplies backfill for ppc providers?

[MHes]

Hi

Anybody know which search engines and/ or directories provide backfill results for ppc suppliers. I know inktomi does, any others?

Thanks

Mirago is quite aggresive in this arena

sure gigablast can be persuaded ...

Google like to do the backfill and PPC

How does one test to see if a site is ranking well on Mirago? Have you an url.
