Performance & Safe Browsing checks (Google, free)

SEO is one piece of the puzzle: speed and reputation matter as much as meta tags. The Performance & safety card runs two free Google checks, with zero credits.

PageSpeed / Core Web Vitals

One click audits your homepage on mobile and desktop: performance score, LCP, CLS, TBT — and when Google has field data, the real-user Core Web Vitals (CrUX). It works even without a key, but the shared keyless quota is tiny: add a free Google API key for reliable runs.

Safe Browsing

Checks that Google does not flag your site as dangerous (malware/phishing) — the check nobody runs until it's too late. Requires the same Google key with the Safe Browsing API enabled.

The key

Create it in Google Cloud Console (Credentials → API key), enable the PageSpeed Insights and Safe Browsing APIs, then save it in Settings → API Keys → Service keys with Test & save. One key is valid for all your sites.
