Best WordPress Plugins for Index

15 plugins compared · Updated August 2026 · Index

All Free only 15 Premium only

Choosing a WordPress plugin for index comes down to a few things: whether it is still actively maintained, whether real users rate it well, and whether it does the specific job you need without dragging the rest of the site down.

We ranked 15 plugins using our WPScore, which weighs the user rating (adjusted for how many people actually rated it), how many sites run it, how recently it was updated, and which WordPress version it is tested against. 15 of them have enough public data to be scored; the rest are listed below the ranked block, clearly marked, rather than being given a number we cannot justify.

How this list is funded. Some links here earn us a commission if you buy. It costs you nothing extra, and it does not move anything up the list — the order comes from the WPScore, which is calculated from public ratings, install counts and update history. See the method.
