I build websites and online stores for a living (from design to fully working and seo optimized sites with WordPress and OpenCart), and I want to find a way to advertise my small agency in Facebook using FB ads.
The problem is simple - how to find the right audience? English in my country is not main language, so it does not offer me much interests for an audience. Targeting online business as an interest is too broad. Using WordPress or OpenCart keywords are also a bad idea, because most of the users that know the platforms don't need help anyway.
How would you look for an audience for such a niche in Facebook?
