500.. if a new sponsor doesn't convert in the first 500 visitors i'd be better off pushing more hits to my own paysites
haha ok actually i don't have a set number.. i normally throw up 7 of my fav FHG's into my php coded 7 day rotator and place them at the very top of the tgp thumbs and if after a few weeks i don't see clicks and or sales i'll move them down or drop them completely
