According to Tech Crunch Facebook advertisers have been complaining about click fraud of up to 100% for weeks.

TechCrunch cites complaints of massive click fraud at WickedFire,

Further the claims of click fraud  here aren’t the typically claims “alleging fake clicks, which obviously never convert to any sort of purchase or other action. But at least the advertisers see the clicks”

“In this case advertisers are saying that Facebook is recording and charging for clicks that don’t exist at all, even from bots. Their tracking software shows one set of numbers, which is 20% – 100% lower than what Facebook is recording.

Facebook responded to Tech Crunch’s report as follows:

“”This is Brandon on the Facebook communications team. I wanted to chime in to make sure that our voice was part of this discussion and to clarify how we are addressing this issue.

We take click quality very seriously and have a series of measures in place to detect it. We have large volumes of data to analyze click patterns and can identify suspicious activity quickly.

Over the past few days, we have seen an increase in suspicious clicks. We have identified a solution which we have already begun to implement and expect will be completely rolled out by the end of today. In addition, we are identifying impacted accounts and will ensure that advertisers are credited appropriately.””
