Click spam (as known as click flooding) is a very common type of mobile ad fraud where fraudsters send a large number of clicks from real app users who haven’t made them. The aim here is to deliver the last click before an install. Fraudsters can send a fraudulent click to an ad from a user who never sees or even clicks the ad. Because it is stealing the attribution of organic app installs, Click Spamming is a type of attribution fraud. 

CTIT analysis and click to install conversion rate can help mobile advertisers to see if their mobile ad campaigns are victims of click click spamming. If CTIT(Click to Install Time) is very short, it can be an indicator of click spamming. Attribution tools and third party mobile ad fraud prevention tools can help mobile advertisers to save their budget from click spamming.
