WordPress performance: find the bottleneck before you rebuild

Guessing is expensive

Installing another cache plugin rarely fixes a slow database query, a heavy page builder, or a hosting limit. Start with a baseline.

A practical sequence

1. Baseline — measure LCP, TTFB, and real-page behavior on the pages that matter.
2. Isolate — cache, runtime, database, plugins, and front-end delivery compete for blame; identify which one is the constraint.
3. Fix in impact order — quick wins first, then structural changes, then infrastructure.
4. Validate — compare against the baseline and note what still needs attention.

Keep changes safe

Prefer staged work and rollback planning over a risky rebuild. If the site is slow, fragile, or hard to change safely, request a WordPress audit.
