Why Your WordPress Site Got Slow

Nobody makes a WordPress site slow deliberately. It happens one reasonable plugin at a time over three years, and each one seemed necessary.

The accumulation problem

A typical audit finds thirty to fifty active plugins, of which perhaps fifteen are genuinely in use. Each loads scripts and styles on every page, whether relevant or not, and several will be querying the database on every request. The total is far worse than any single addition.

Audit before optimising

Use a profiling plugin to see which plugins and queries actually consume time on your slowest pages. The result is usually two or three culprits rather than a general fog, and it prevents you spending a week on image compression when the real cost is a related-posts query running on every load.

The reliable wins

Deactivate and delete what is unused, replace heavy multi-purpose plugins with focused ones, add page caching and object caching, serve images in modern formats at the right size, and move to hosting with current PHP and a real database. That sequence recovers most of the lost speed on most sites.

Then hold the line. Adding a plugin should require a reason and a check of what it loads, or the site will be back here in eighteen months.
