Nano plan visits have stopped

For my website, Google Analytics is active and UA ID hasn’t been changed. I have recently taken Nano project first to see the traffic flow before buying the premium package. However, for my website only for the first day 200 hits have occurred and around 40 visits only for the next 2 days. what would be the reason? Thanks.
