What's your subscriber conversion rate?

Since Launching my site Slidegame.io 5 days ago my current stats are:

• 715 unique visitors
• 94 Subscribers

So I have a 13% sign up rate.

• would be great to understand if I'm doing well compared to other sites
  Any suggestions on how I could improve would also be great

Thanks!
