I agree with the other comments here that you're better off just hosting it yourself. Though, if you go down the path of considering commercial services check out y.gy (note: I'm affiliated). It would allow you to see where people are clicking from (Twitter, Reddit, etc.) and where they are clicking (city-level). It _could_ be useful depending on your traction.

It's a fruitful discussion with a lot of nuance and yes, disagreement. Nothing here seems against guidelines
