Purpose

What this guide helps you check.

This check focuses on practical speed fixes: oversized images, unnecessary scripts, slow HTML response, and layout shifts.

Review checklist

Work through each signal.

  1. 01

    Compress large images.

  2. 02

    Remove unused scripts from key pages.

  3. 03

    Check visible layout shifts.

  4. 04

    Retest after each repair.

Verification workflow

Close the loop with evidence.

  1. 01
    Open the published page

    Check the final public URL rather than relying on an editor or preview screen.

  2. 02
    Verify both layouts

    Review desktop and mobile presentation, links, actions, and visible content.

  3. 03
    Run the final test

    Measure the released page and separate unavailable provider data from passing checks.

  4. 04
    Record the result

    Keep the report link with the project so the launch decision is traceable.
