Why a Website Is Slow: Start With Images and Page Weight
Page speed is affected by the device, connection, server, code, and third-party services. Measure a representative page before optimizing.
What to do
- Test the page with a performance tool and note the largest images, scripts, stylesheets, and any slow server response.
- Resize images close to their displayed dimensions and export an efficient format that preserves acceptable visual quality.
- Remove unused assets and defer nonessential scripts where appropriate; test interactive features after each change.
- Repeat the measurement on mobile and compare the same page under similar conditions.
Checks and limitations
- Image compression is lossy for some formats; keep an original and inspect text, edges, and fine detail after export.
- Do not defer scripts blindly: navigation, consent controls, and tools may depend on correct loading order.
