When I used referrals I always included one link to it. Adsense says one referral is allowed per page. But what about multiple links to one referral, is that allowed? Anyone done this?
Why do so many people think it's just 1 referral? It's 3. "Up to three referral units may be displayed on a page, in addition to the ad units, search boxes, and link units specified above." Source: https://www.google.com/adsense/support/bin/answer.py?answer=48182
Probably has something to do, because it was 1 in the past and who reads the TOS and updates of every website. If I did it would probably take me a year to go through all websites I'm a publisher off. And so would most webmasters
