Looks like I was wrong with my last post – apologies – but even more exciting than that is that Adsense have just launched a referal program. Now you can refer new publishers to adsense and earn $100 when they get to their first $100 of earnings.
There are a variety of buttons to choose from (no text links) to promote the referral program. Here’s some:
Note that these are not live buttons – it would be against Adsense TOS to include more than one such button per page.
There’s also apparently a referral program for US publishers for dowload of firefox with the Google Adsense toolbar which pays $1 per download. I don’t see the option for this in my Adsense package of course as an Aussie publisher.
I’m not sure if I’ll really heavily promote this program – I don’ t know too many publishers who haven’t already registered for Adsense. I suspect YPN will have a similar program which would be much more lucrative in terms of how many possible sign ups could be generated.
