Hi, it looks like you clicked on the number at the bottom of the page because you’re curious about it! I respect your desire to know and understand the world around you.
This is the hit counter. In the manner of hit counters on very old websites, it naively counts every page request received and displays the current count at the bottom of every page.
It is not a count of the number of people who have visited each page — most of the page hits are probably due to search engines and other automated requests. Also, it double-counts users who visit the same page more than once.
However, while the specific numbers are fairly meaningless, the relative counts do provide a rough measure of the relative popularity of each page.
