Do AdSense referral set cookies when a user clicks, so that if a user comes back to the same site later, you still get credit for it? I know a lot of affiliate programs do this, and I thought I remembered reading about this for AdSense referrals too, but now I can't find anything about it in AdSense help. TIA
Thank Micromag. That helped me find the answer in AdSense help: https://www.google.com/adsense/supp...9&ctx=en-uk:search&query=30+days&topic=&type= says:
