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. WebsiteLinter runs all four checks in a single 30-second pass and returns a prioritized fix list.

Question 2

Is WebsiteLinter really a free website health checker?

Accepted Answer

Yes. You get 3 free health checks per day with no signup and no credit card required. Unlike PageGuard, we do not gate basic results behind an email wall or push aggressive upsells before you see your scores.

Question 3

How does WebsiteLinter compare to PageGuard?

Accepted Answer

WebsiteLinter offers deeper security-header analysis (HSTS, CSP, X-Frame-Options, referrer policy), true WCAG 2.1 accessibility scoring, and no forced signup. PageGuard focuses primarily on SEO and performance, with lighter security and accessibility coverage.

Question 4

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 5

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, structured data), TLS and security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options), and WCAG 2.1 AA accessibility findings — all rolled into one composite health score from 0 to 100.

Question 6

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. The whole audit completes in well under a minute and adds no measurable load to your origin.
