Facebook can only imagine a CTR of 0.5%.

Several articles such as the one at BizReport say that Facebook has a CTR of 0.04%. Assuming there are five ads, that is 0.25% for a page view. Half of what I predicted for a web site. Reason given for Facebook’s problem is instant messages and an audience that is not interested in other products. I have not used Facebook, but I assume each IM is loading a new ad. So Facebook may actually be close to 0.5% and be diluting the ads by increasing the number of page views. The real problem is that Facebook is losing money and they may already have maximized revenue for text ads.
