Out of those, Mainstreet just started converting, just before I cleaned house.
Don’t know what happened to togo and canada. Richwebmaster dropped them and so did I, they were not converting anyway.
I just cleaned up my page so you can see who works for me, not all equally, at http://www.gamesandcasino.com/featuredbingo.htm
How many per visit convert varies not only from Bingo to Bingo, but even more so from traffic source to traffic source.
