I have 20 domains that generates some cash thru the year with the Amazon affiliate program. I think I could get more money with Adsense... How can I set this up? Merci!
First signup for Adsense at google.com/adsense and then put the ads onto your site. The hard part is blending them into your site.
You can't make money using adsense with just parked domains, it's against the TOS. Unless you're doing massive amounts of traffic, then they have a special parking service you can use. If all 20 domains are on the same topic, I'd suggest picking one of the domains and making a small website made up of articles (you can find many articles for free online) and placing adsense on this site. Then just redirect the 19 other domains to this new website and you'll hopefully start making adsense revenue.
