PageSpeed Insights issues

Common issues for PageSpeed Insights errors and how to resolve them.

Status code 404

If This

You view lots of❗️red exclamation points and a status code of 404 for your preview (.page) or production (.live) storefront URLs.

Check This

Red dots indicate that the page has not been published or previewed since last edited. The 404 error only happens if you’ve never published or previewed the page you enter into the PageSpeed Insights text field (which includes your index page when you only enter your site’s URL). So because you never published the page (using Sidekick), Edge Delivery has not yet added the page to the preview or production CDNs, where PageSpeed Insights (and everyone else on the internet) looks for it. The result is a 404 error.

Do This

1. Publish or Preview the page using the Sidekick buttons.
2. Clear your browser cache.
3. Wait a minute or two for the page to be added to the preview CDN (Preview button) or production CDN (Publish button).
