After figuring my Clickbank affiliate analytics in 30-day time-frames...6% of my affiliates are bringing in 50% of the click-thru's...
CONGRATULATIONS AND MY DEEP APPRECIATION TO YOU BUSY 6%.
But...that means 94% are bringing in the other 50% of the click-thru's...why aren't you 94% doing more? There's FREE MONEY to be made! Clickbank has paid out over ONE BILLION DOLLARS to affiliates in the last TEN YEARS...obviously most of it to the top few percent who bring in all those clicks that lead to all those sales! Message to you lower 94%...advertise more!
