What's a good engagement rate on facebook marketing?

Hi, I'm a beginner to dropshipping. I started to mess around with facebook marketing a few weeks ago with a small budget. One ad I tried performed a lot better than the previous ones and got me my first sales. Right now it has around 5000 views, 430 likes, 35 shares and 15 comments. That's almost a 10% engagement rate, and I was wondering if that was standard or did I just hit a goldmine? Thanks!
