What category size and maintenance mean when choosing
The category is broad, but plugins with higher install counts make up a smaller part of it.
There are 1,056 plugins in the category; 42 have at least 10,000 installs, including 9 with at least 100,000. That distribution gives readers a range of options, while showing that the largest adoption levels are concentrated among relatively few plugins. 47% were updated in the last year, a useful maintenance indicator to compare alongside a plugin’s fit for a site’s needs.
