Can I mention tracker Phone number in Facebook Calls Campaign ? Tracker will route the calls to affiliate network unique phone number. As per Facebook Ads policy is this allowed? What is the best possible way to promote Pay per call offers using Facebook Ads without affecting its policy.
Moreover Affiliate networks (Market Call & Click Dealer) will allow the conversions without landing pages?
