Question 1

What is a website health check?

Accepted Answer

A website health check is an automated audit that scores your site across four pillars — SEO, page performance, security, and accessibility — and flags the specific issues hurting your rankings, conversions, or compliance posture.

Question 2

Is the WebsiteLinter health check really free?

Accepted Answer

Yes. You get 3 free health checks per day with no signup and no credit card required. Upgrade to Pro ($9/mo) for unlimited scans, history, and PDF export.

Question 3

How often should I run a website health check?

Accepted Answer

For most small-to-medium business sites, monthly is the right cadence. Run a check after every deploy, theme change, or plugin update — those are the moments performance and security regressions creep in.

Question 4

What does the health check actually measure?

Accepted Answer

Core Web Vitals (LCP, INP, CLS), Lighthouse performance score, on-page SEO signals (title, meta description, headings, canonical, robots), TLS and security headers (HSTS, CSP, X-Frame-Options), and WCAG 2.1 accessibility findings.

Question 5

Will the scan slow down or break my website?

Accepted Answer

No. The check loads your public pages once, the same way Google's crawler does. It does not log in, post forms, or hit private endpoints — and it respects rate limits.
