I have spent years trying to do effective marketing on Facebook and to this day after spending nearly $2000 on the platform still have not had a single converted inquiry and only 3 semi-qualified leads.
I have tried so many different techniques in delivering ads. From Post Boost, Video Ads, multi-image ads, single image ads, copy that works in my AdWords PPC world, off-site landing pages and in-Facebook lead collection. Every time I get near 0:00:00 time on my landing pages and no collected leads within the Facebook ecosystem. It boggles my mind when one can really hyper-target audiences that it seems that the only people clicking are click-farms/click-bots. Oh and for off-site pages it seems that at least 70% of clicks are phantom clicks.
What makes marketing in general difficult is that in my industry you don't really get repeat customers, so while branding is critical brand loyalty just means the possible WoM referral. So I am in a constant push to find 30-40 clients who sign a contract every year (averaging about 200 inquiries in a year).
So I am hoping that maybe some success stories can be born from this thread. Otherwise, at least in my space, it's just not an effective medium.
