The Eighth Day with Facebook Ads

I tried to target people who are interested in languages and Chinese (learning Chinese) and I've supposedly received a total of 53 clicks (out of 407,104 impressions). So far, I haven't gotten a single purchase, even though the Rocket Chinese samples seem like a good way to learn. I changed my ad a little and changed the demographic I'm targeting, so hopefully it'll be more fruitful this coming week. I'll keep you posted.
