First time that happened. My reply took forever to post and finally failed. Lost the entire thing.

Bottom line is you can get useful info about which media channels bring the best return and which adverts are the most effective. Without measurable feedback you might as well be a blind boxer hoping each swing of your fists will connect.

beg to differ ~A well thought out and designed campaign will be to onboard people signing up to Bitshares accounts. That means an ad where people click, and arrive at a landing page. At that landing page they will spend some time to explore, and sign up there and then or possibly later; for which follow up is required and managed via cookie/capture/opt-in etc.
Every click and signup is measurable in a professionally run SEM campaign.
