Performance advertising

I got an offer from an advertiser willing to advertise in my fashion blog. But they are asking me if i  do performance advertising. I’m having second thought about their offer because i have joined three companies like them but i didn’t get my earnings at all. One of them is still pending until now because i can’t reach the payout limit yet and the other two have already shut down their sites without giving me my earnings. Performance advertising  is good only for SEO experts cause they know how to make their sites well targeted by visitors.
