How to Run a Website Plugin Performance Audit
Use repeatable before-and-after tests to understand scripts, layout shifts, real user journeys, and whether a plugin earns its place.
Measure a real visitor task under repeatable conditions. This collection starts with a plugin audit that records the baseline, changes one component at a time, inspects delivered resources, and keeps measurement separate from interpretation. Use the result to inform a specific maintenance decision. A single score or plugin count does not explain the whole experience.

Use repeatable before-and-after tests to understand scripts, layout shifts, real user journeys, and whether a plugin earns its place.
Pick a landing page, a detailed content page, and a page that actively uses the feature under review. Write down the device conditions, account state, cache conditions, and the exact visitor task. Repeat the baseline so that you can see ordinary variation before attributing a difference to one component.
Change one setting or component at a time in a controlled environment. Preserve the feature’s essential function while comparing results, and record failures as well as improvements. Use the maintenance guides to turn your findings into a decision record and the websites directory to investigate suitable alternatives.
