My word count plugin, WP Word Count, just recently broke passed the 4,000 active installs mark on the WordPress.org plugin directory.
I had been watching this number for months as a simple means to compare my plugin’s performance against similar ones that are out there. Doing a simple search for “word count” shows that WP Word Count is the most installed free word counting plugin in the wild right now.
Then I realized I didn’t really know how this number was calculated.
How does WordPress figure out how many websites are actively using my plugin?
