Someone on STM asked how they can find their demographic using the insights tool, so I decided to help him out, but also decided why not share with you – because this method works, and really well for any vertical.
1) fire up audience insights tool
2) find the top VERTICAL-RELATED sites on google in the GEO you are working in
3) into the interest section on audience insights, start typing in their name, when you find a match add it, then add every single vertical-related site in here
4) after you added all, click pages tab, and sort by affinity – you want the top 5 highest affinity fan pages on FB related to sites like these
5) setup new camp, targeting 1 interest per adset 18-65+ with 1 ad.
