I have just made my very first ad with facebook. It is just a simple clickbank product about improving a golf swing. I followed instructions from a WSO that said you don't need a landing page and can directly link. I wasn't sure if that was true but I tried it out anyway. The ad was approved but when I tested to see if the link worked, facebook gave me a notice saying that is is potentially harmful site or something like that. So does that mean I need a landing page?
If so any suggestions? Word press, weebly? or actual domain?
