Facebook Ad

Hi Brooke,
Thank you for introducing me to Claire Pelles, I’ve followed her instructions and set up an ad to drive traffic to my landing page.
Can you take a look at my stats and tell me if it’s good or should I try to get better? The ad started in mid November.
Impressions 2791, Frequency 1.54, CPM$16.85, CTR (click-through-rate) 3.65%, link clicks 102, CPC (cost-per-click) $0.46, Sign-up/Opt-in 60, Cost per sign up $0.78
Are they good? Claire doesn’t go into what is a best stat to aim for.
Also, I started the campaign with $5 per day, and now reduced it to $2. Shall I keep it at $5?
Thank you!
