I never check it. It's simply not worth it at this time. In fact, in regards to my drumming forum, I'm just waiting to bring in traffic from my huge Facebook page, but there simply isn't any money right now.
I check it about maybe once every week or 2. I recently just made the jump from vbulletin to xenforo 3 days ago and it's been about the same at roughly 12K UV's per day according to cloudflare.
I find that if you look at analytics too often you tend to get discouraged so it is best to not always check your traffic or any other analytics too often and only check it periodically.
I check my website’s traffic once a week, however, I check my search traffic twice a week. I like to keep track of what keywords are performing the best and bringing in the most traffic.
