There are lots of users using Google Affiliate. But I didnt understand, if no one will buy any product from Google Affiliate link then what? That webmaster's blog will die without money.
There are many ways to earn through webmasters blog, dont depend on google affiliate link. try putting hosting affiliate link in your webmaster blog as many webmaster looks for hosting in such type of blogs. You can generate money through Ads though.
As you know google is bigdaddy internet , they are more trustworthy and they have high conversion rate thats the reason for more site using that.
I think Google's Affiliate program is great if you can get an invitation, since it's Google many merchants will trust it
They jumped into CPA too...duh ! ...in 2012, you will find them offering web hosting solution...Honestly, I believe google has worst support or in other words they just don't care for publisher...I personally don't have any encounter with them but I have seen people mostly complain that google doesn't reply to their e-mails & their appeals are hear by deaf ears..Google ban straight away if adsense publisher become victim of click bombing...I mean how come it's publisher fault if I decided to click bomb or send Iframe traffic to someone website with adsense ads ?...Google pays good because they shave earning from their banned publisher. Clickbank & amazon is far better.
But somewhere I have seen that they are also paying for clicks? Means if any will click on the google affiliate link then google will pay without purchase of that product. And also they pay for impression.
Google affiliate is perhaps the best affiliate marketing program.From there, there r lot of ways u can earn money. For that u have to know the concept of cpa,cpc,sem.
Sure why not, the advertisers would be more legit than on ClickBank that's for sure. CB advertisers are a bunch of nobodies comparing to some networks.
