What category size and update activity mean when choosing
The category is broad, but only a small group reaches the highest install bands: 9 plugins have at least 100,000 installs, and 32 have at least 10,000.
Recent maintenance is uneven across the field. 61% of category plugins were updated within the last year, so install counts and update activity offer different signals when comparing options.
