1) FindWhat (50% of the Bid, if you qualify for their program) 2) Searchfeed (they pay 30%-50% but most of their feeds are from findwhat so it is like 15% - 25% of the FindWhat bid Amount). 3) Search123 (50% but the Advertisers are not reviewd, so may not get targeted ADs) 4) epilot - (use their local direct program, very good program for yellow pages content) 5) 7search - Have not used them.
I would add RevenuePilot between SearchFeed and Search123.
I visited all sites above, but I didn't really find where I'm looking for. I'd like to setup a new domain and make the site a search engine with sponsored results. Would be nice if it could return additional non-paid results too, from for example DMOZ. Main purpose is to dump some excessive traffic there and make some additional money from it. But a site like this does not meet the requirements they ask for.
Seek99 has low bids but payments are processed in 24 hours - a big +. OneSearchPlace has slightly higher bids but payments are processed in 48 hours. You can expect at least Net 40 with the rest of them.
