Amazing article. One question I have is about how to avoid the risk of FB terminating an ad account for using it to drive traffic to this kind of landing page. The first part of that question is, do you think a simple opt-in page like you described (with no content other than a "hook" that FB might argue is deceptive) would result in the ad being disapproved and possibly the ad account at risk of being terminated? The second part of the question is do you think the FB ad itself would need to be toned down, or do you think it's safe to just repeat the hook? It seems like FB is getting more and more strict about this kind of thing.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
