The AdSense Blog announced that they have added a validation period to non-Google referral products within the Google AdSense referrals console.
The blog post explains: "For some publishers who display referrals for non-Google products, the earnings you receive for the ad may now be less than the maximum referral value displayed for that ad. This is because our system will initially place a restriction on referral earnings as we monitor click and conversion data to determine that the conversions generated are valid. Once this validation period ends, you'll begin earning the maximum value of the conversions as displayed in your account.
We can't say precisely how long the validation period will last, but will make every effort to ensure that it's as speedy as possible. It will vary by publisher since site activity is different for everyone, and we anticipate that the majority of you will be minimally affected. However, advertisers will only be charged the maximum referral value once a publisher has completed the validation period."
