No. GA Top Posts is built to be lightweight and fast. Analytics data is fetched from Google on the server side and cached in your WordPress database, so visitors never trigger a live API call — they always read from the cache. You control how often the cache refreshes (every 1, 2, or 6 hours) from the plugin’s configuration page. Thumbnail images are used instead of full-sized images for faster load times on the frontend.
Yes. Because GA Top Posts caches analytics data server-side in the WordPress database, it is compatible with page caching plugins such as WP Super Cache, W3 Total Cache, LiteSpeed Cache, and Kinsta Cache. The frontend widget reads from the database cache and does not make live API calls, so it works correctly even when full-page caching is active.
