What this tool checks

Check the response behavior that affects security, caching, compression and browser delivery.

WebMetrica uses the same underlying scan engine for this focused tool and the complete website analysis, so you can move from one specific answer to the broader report without running a separate product.

How to use it

  1. Enter a public website or page URL.
  2. WebMetrica runs the relevant checks and browser measurements.
  3. Review the focused result, then open the full 63-check report if you want the complete picture.

Frequently asked questions

Which headers are checked?

The report currently evaluates key security, cache and transfer-compression signals captured during the scan.

Why are security headers important?

Headers can reduce browser-side risk and define how content, transport and referrer information are handled.

Why might a header show as unavailable?

Some intermediaries, CDNs or browser behavior can make a specific value unavailable to a passive public scan. WebMetrica reports that instead of inventing a value.
