Check a page simply with PageSpeed Insights

PageSpeed Insights checks a public URL and reports technical and user-experience suggestions.

Enter the full URL of an important page, not only the home page.

Read mobile and desktop results separately because their conditions differ.

Open high-impact or red findings first and read each explanation.

Choose one small change, such as shrinking a large image or removing an unnecessary script.

Keep a backup of the page and related settings before changing them.

Apply the fix, clear caches, and test the same URL again.

A single run can vary slightly, so compare several tests under similar conditions.

Do not chase a perfect number alone; consider real speed and usability too.

Keep a simple table of the issue, change, and next result so progress remains visible.
