SEO Low impact Easy informational

Technologies in use

An overview of the site's CMS, frameworks, and libraries.

What it is

Technology detection determines what the site runs on: CMS (WordPress, Shopify…), frontend framework, analytics, CDN, server software, etc.

Why it matters

By itself it's not an SEO problem, but it's useful for an audit: outdated versions may have security holes, heavy frameworks slow things down, and knowing the stack helps with optimization and maintenance.

How to do it

1Check whether the libraries/CMS in use are outdated (security, performance).
2Consider whether heavy third-party scripts (widgets, trackers) are worth it.
3On a slow site, look at how many and which technologies are loaded.

Conclusion

This is more of an informational overview than a list of errors. Use it to uncover outdated or needlessly heavy components, then address those under speed and security.
