Common questions
What is the fastest way to improve WordPress performance?
The fastest wins come from finding the main bottleneck first — slow queries, bad caching, oversized media, render-blocking assets, or weak hosting.
Do caching plugins solve every performance problem?
No. Caching helps, but it cannot fully hide bad queries, heavy plugins, poor theme architecture, or weak database performance.
How important are Core Web Vitals for WordPress?
They matter because they affect user experience, perceived speed, and search visibility. WordPress sites often need specific work on LCP, CLS, and interactivity.
Should I profile WordPress before making changes?
Yes. Profiling prevents blind optimization and helps you spend time on the parts of the stack that are actually slow.
