Stumbleupon, AdSense Account Banned for Invalid Impressions Fraud

I know this sounds very hard to believe but it is a real fact and many webmasters that practice Stumbling had felt it. The wost thing about that is that most of them didn’t really realized what they were doing wrong as their visitors did not do any click frauds, and therefore there was no reason for their account to be banned. In reality Click Frauds are one of the many CPC frauds on the Internet.

The similarity in all banned from AdSense webmasters was that they all used massive stumbling as primary traffic source. Also and Google sent them email stating that they ban/terminate their accounts for invalid ad impressions, but didn’t explain what exactly that meant bu that, and actually I didn’t know also until I found one book on per-per-click marketing book where the I stumbled across the term invalid impressions fraud.

A large number of impressions, without the accompanying click on your ad.
if you notice that there are a lot of impressions (views) of your advertising, this could indicate impression fraud. Impression fraud is artificial inflation of your ad impressions that may cause your ad click-through rates to drop below the Google minimum and your ad will be disabled. Until you realize this, your competitors have free reign to use your keywords, sometimes at bargain prices. As well, your relevancy ratings for search engines may drop as they record numerous impressions, but no interest shown via visits to your website, which could lead to a shutdown of your campaign.
