Why this matters
Conduct a plugin audit quarterly: list every active plugin, identify its purpose, and ask whether it provides measurable value. Scrutinise especially: slider and carousel plugins — almost always replaceable with CSS; page builder plugins no longer actively used; social sharing buttons — often heavy and easily replaced; chatbot plugins that load on every page; and multiple overlapping optimisation plugins that may conflict. This complements server-side caching — a faster server and fewer plugins compound each other's benefits.
For each plugin you keep, verify it is actively maintained — last updated within the past year — and compatible with your current WordPress and WooCommerce versions. An unmaintained plugin is both a performance risk and a security vulnerability.
Use the Query Monitor plugin to identify which plugins make the most database queries per page load — this reveals which have the biggest performance impact. When removing plugins, deactivate first and monitor your site for 24 hours before deleting, as some store data other parts of your site depend on. After each removal, run a PageSpeed Insights test to quantify the improvement. Fewer plugins also means a smaller attack surface for security.
