AdSense have made a change to their referral program by putting a validation periods on publishers when they display non Google products. In this period publishers earn a lower conversion commission while AdSense works out if your conversions are ‘valid’. Once the validation period ends you then will earn the maximum commissions on the product.
It seems like this a system to combat some sort of problem that AdSense must be having with invalid conversions (some sort of ‘conversion fraud’ perhaps?).
AdSense says that the validation periods will vary from product to product and attempt to sell the change by saying that it is to ensure the ‘long-term effectiveness of the referrals program for both publishers and advertisers.’
I’d be interested to hear if anyone who has tried the referrals program has seen any real conversions from any products other than the Google products (AdWords, AdSense, Firefox etc)? To be honest I’ve only ever found one blogger who seems to be doing any good with non Google referral products.
