So I have a fanpage I created and it has a decent amount of people converting at ~40%....I had a link to the page linking to the CPA offer a php direct from my domain name. I thought it would convert better if I iFramed the offer in the facebook fan page. So when the user clicks the button to the offer, it pops up in an iframe below the clickable button. Is this against the TOS of facebook? I was reading, and my understanding was that it was legal if you linked to it.
