For now and for the forseeable future I wouldn't waste any time on AV. We put over 1500 pages in one of their inclusion programs and rarely see more than 10 referrals per day (no didn't pay the $78.00/page/year).
Teoma is slightly better and IMO they have a future unlike AV.
I was taking the view that as Overture has just bought them, any PFI sites would likely do well if & when they integrated all their indexes?
Are your 1,500 pages appearing highly in the SERPs? I'm doing ok on most of the SEs, but AV bugs me. I've done PFI on AV and my pages only started coming no. 1 after 3-4 months of not touching them. Bizarre....
Any clues on how to improve this situation would be most welcome! J
