http://clickfraudnetwork.com/content/ClickFraudIndex.aspx Overall click fraud rate in % for content networks in 2007: 25% It was 'only' 19% for Q4 2006. AdSense publishers are really in deep s..t You better switch to CPA if you can
That really sucks. Maybe Adsense or other CPC networks will soon become a back seat in internet monetizing.
But this rate grows because of that they improve they algos to detect it (amongst the others). I think publishers aren't in any 'shit' like you mentioned above.
This is not for adsense but for all cpc networks. Adsense is great at countering click fraud. The true figure for adsense would be below 10%. Also, Clickforensics always overestimates click fraud because its in their interest to do so. I also think its a good thing if adsense reduces payout to all publishers by a certain percentage to keep money aside so it can repatriate to advertisers that had been victims of click fraud.
