Read a speed claim without falling for it.

Five focused guides turn Lighthouse scores, Core Web Vitals and “lightweight” claims into decisions you can repeat on your own project.

Measured

Numbers need conditions

Always record the URL, device model, tool, date, version and run aggregation.

Field

Users need percentiles

Core Web Vitals describe real user experiences at the 75th percentile—not one clean run.

Editorial

Fit still needs judgment

The lowest metric is not useful if the design, workflow or commerce model cannot serve the project.
