How do i get people to click on the referral signups? I put a few on my site but i aint even got any clicks. I saw someone on here before who said they get on average 30 signups a day! how do you do that?
Well, if you have a large traffic, neturally you're going to have a higher chance of getting one. Whether you can benefit from it or not is mostly luck.
It's a good part luck like Ready2Go pointed out. Also, it depends on your site's niche. A webmaster-based website is more likely to benefit from adword referal ads than a gaming website..
Don't just slap the link/button on your site - integrate it with your content, endorse it, SELL it.. For some examples see this link: https://www.google.com/adsense/support/bin/answer.py?answer=43870&topic=8972 and like Jake said, if your site's niche isnt compatible with the referral, dont expect many conversions.
I don't like Referral Buttons because they aren't very effective....use other forms of adsense because they will get you nice profit if you know how to use them well!
