I found an affiliate program, it is selling a subscription for an MMORPG. I would like to know what is the conversion rate when selling such a product through PPC, in other words if I get 100 clicks from Adwords, what percentage of it would convert to sales? I would like to hear from people who had experience with similar ventures. Thank you.
You wouldn't know the conversion or ROIt for any PPC campaign unless you build and try out yourself. The ROI and conversion depends on many factors like quality of Landing Page, the quality of Ads etc.
Off course, but I would like to hear people who had similar campaigns, I am interested in current fluctations of the game industry and overall how well does it convert including all the factors you stated.
