Ask HN: Are majority of Facebook Ads visitors fake?
I want to ask people with facebook ads experience, is it fake 90% of the time. How has been your experience with FB ads, did it result into sales?
If you're targeting to a developing country, then you need to then filter by profession (e.g. Software Engineers, CTO, etc.). Some countries (notably Vietnam, Philippines, and Bangladesh) have fake account farms where they sell fake likes or do shady stuff like click on their clients' competitors' ads to they can jack up their cost.
Also, look into using re targeting when they are back on a desktop.
