Judging by GA statistics, my young site is visited by 20 people a day. At the same time, Hotjar recorded 100 visitors in just 2 hours. These are really unique visitors with long sessions.
How is this possible? Also, indirect confirmation of the fact that the traffic is actually much more is Ahrefs statistics. This service points to 12,000+ unique visitors per month https://exoticfonts.com/
