1. Go on youtube and find few big youtubers
2. Create g+ profile with same names as those youtubers
3. Create youtube accounts as theirs and upload few of their latest videos and add your cpa offers links on those videos.
4. Look for their lastest most viewed videos and make comments pretending that you are them (you can put your website link,write something check this out and add link)
Since people think that you are the real youtuber, they'll like your comments and keep it on the top.
With this method by posting just 3-4 comments,in 1-2 hours I get more than 500 visits to my website and 20-30 clicks on my offers.
