Facebook ad campaigning: is it for Edgeryders? are we doing it wrong? can we improve?

We wanted our announcement for a program curator and 15K monetary compensation to produce bigger interest and deliver interesting proposals and content at OpenVillage Fest. Enter facebook: during 29 Apr - 4 May (6 days) we scheduled a campaign with 3 adds, same text and different pictures. They all linked to our announcement https://edgeryders.eu/en/communityfellows.

Basic analytics:

URL total clicks: 3,234 (of which 80% in the first half of running the ad!?)
