This quotation is from a 2018 topic. Has anything changed since then? What I’d like really is “x unique visitors per month” so that I can get an average for various periods.
Be wary of comparing it to e.g. Google Analytics on your website, since they will be using different assumptions in their calculations. (e.g. we’d be consolidating IP-addresses/devices based on user name, while GA would be blissfully unaware of usernames).
