Squat.net offers simple web statistics to get an idea how many human web visitors your website roughly has.
These results are anonymized and not very accurate, but can still be useful.

How does this work ?
After you have requested web statistics and after this has been configured for you, then log in to your squat.net website.
You should see a little graph at the top middle.

Click on the graph. You should see the statistics.
