Page has broken JavaScript

A missing script can silently break interactivity, forms, or even rendering on JavaScript-heavy pages.

What it is

This check flags <script src> references that return an error such as 404.

Why it matters for SEO

Broken JavaScript can prevent content from rendering for crawlers and users, and leaves features non-functional.

Example

<script src='/js/app.js'></script>   ->  404 Not Found

How to fix

1. Restore the file or correct the src path (check hashed build filenames).
2. Verify asset versioning does not point to stale URLs.
3. Remove references to scripts you no longer ship.
4. Re-crawl to confirm scripts load.
