For the last year I was converting about 1 in 100 clicks. Around $100 per sale The last two months I have made no sales in around 1100 clicks. What was a constant $500 a month has dropped to nothing. I have not done anything different to promote the site and the amount of clicks have gone up very slightly. The code has not been changed on my websites. All my links are organic. Anybody have an idea what could be happening?
It could be that your readers have already checked out the banners that you are promoting. Have you tried switching the ads up a bit? Have you been getting new visitors or repeat visitors in the past few months?
