Meta description changed by JavaScript

Warning severity, in the JavaScript tab

Why it matters

The meta description in the HTML response differs from the rendered one; snippets may be built from either.

How to fix it

Render the meta description server-side instead of injecting it with scripts.

How Crawlune finds it

Crawlune flags Meta description changed by JavaScript automatically on every crawl and lists the affected URLs under the JavaScript tab, where you can filter, inspect each page and export the list to CSV. The free version crawls up to 550 URLs with every check enabled.
