Honestly Google is everywhere. It has not need to get extra advertising. Furthermore, seeing all these invalid clicks AdSense accounts banned often without good reasons makes me think it is time to have better alternatives. AdSense seems the best program related to the earning aspect, but for the reliability I give it a big thumb down. We need to refer other companies to equalize the market more fairly.
Yep. Does anyone know why they were removed in the first place? What do referrals have to do with Google's advertising? and the rest of your reply is irrelevant.
It's enought for Google and they dont need now. But publisher alway need They do what good for them, and shut down the refferal is one of them
Sure it is better for the publisher to get more opportunity to earn. Frankly speaking, adsense for referrals is good to earn money
