What Triggers This Issue

This issue is triggered when URLs include a meta fragment tag indicating that the page is still using the Old AJAX crawling scheme, which was officially deprecated as of October 2015.

For example:

https://www.screamingfrog.co.uk/

Has the meta tag:

<meta name="fragment" content="!">

How To Fix

Update URLs to follow JavaScript best practices on the web today. Consider server-side rendering or pre-rendering where possible, and dynamic rendering as a workaround solution.

If the site still has the old meta fragment tag by mistake, then this should be removed.
