Plugin Graveyard
The Plugin Graveyard is the slow accretion of WordPress plugins added over years — analytics, forms, sliders, optimisers — each injecting JavaScript and CSS into every page load. The site appears to function. The admin dashboard looks normal. Core Web Vitals quietly fail.
The full canonical article for this concept is in preparation. In the meantime, see the related coverage below.
Common Questions
What people ask about Plugin Graveyard
Why is my WordPress site so slow?
Most slow WordPress sites suffer from the Plugin Graveyard — years of accumulated plugins each adding JavaScript and CSS to every page load. The admin dashboard looks normal, but Core Web Vitals quietly fail. The fix is auditing each plugin's actual contribution to load time and removing or replacing the heaviest offenders.
How do I find which WordPress plugin is slowing my site?
Use the Query Monitor plugin to log each loaded asset by source plugin. Combine with a Chrome DevTools network waterfall to see render-blocking resources. The biggest offenders are usually page builders, slider plugins, social-sharing plugins and security plugins running on every request.
How many WordPress plugins is too many?
The count matters less than the cumulative weight. A site with 50 well-coded plugins can outperform one with 8 heavy page-builder and slider plugins. Measure the JavaScript bundle size and request count, not the plugin count.
Why do WordPress plugins conflict with each other?
Multiple plugins often load competing versions of libraries like jQuery, all hook the same WordPress filters, or fire conflicting event listeners. The result is unpredictable behaviour, JavaScript errors and performance collapse. Plugin Graveyard sites typically have 3-5 unresolved conflicts simultaneously.
