What slows a store page down on phones?

The common causes are oversized images, apps that load scripts on every page, and heavy fonts or video. PageSpeed Insights lists which files add the most weight, so you can see what to fix first.

Why are my PageSpeed results different every time?

Single runs vary with network and server conditions. Run each page three times and use the typical result. Compare before and after a fix the same way, so you know the fix really helped.

Can I do this with ChatGPT or another assistant?

Yes. Any assistant that can browse, including ChatGPT, Grok and Muse, can run PageSpeed Insights with this prompt. If it cannot browse, paste in the report and ask it to rank the fixes.

Which pages should I test first?

The pages your ads link to, starting with the one that gets the most paid clicks. Most ad clicks come from phones, so always test the mobile version rather than desktop.

Your top ad page is slow on phones

Most of your ad clicks are on phones. How long does your page take to load there?

Ad landing pages are often slow on phones because of oversized images and apps that load scripts on every page. Give Claude web browsing and ask it to run PageSpeed Insights on mobile for each ad landing page, then rank fixes by time saved. Fix the top two first, and run each test three times.
