Why Website Health Audits Matter

A website health check looks beyond surface-level scores to diagnose the root causes of poor rankings, slow load times, security vulnerabilities, and accessibility barriers. The four pillars — SEO, performance, security, and accessibility — are deeply interconnected: a slow site hurts SEO rankings, a misconfigured security header can expose visitor data, and poor accessibility affects both legal compliance and search indexability. Running a health check monthly catches regressions before they compound into lost traffic and revenue. Whether you call it checking website health, a free website health check, or an HTML SEO checker, the job is the same: read the HTML, HTTP headers, and rendered page your server actually sends and flag everything that hurts rankings, trust, or usability.

What the Website Health audit checks

Deep, actionable signals that generic checkers miss.

SEO health — title tags, meta descriptions, canonical tags, schema markup, and indexability signals

Core Web Vitals (LCP, INP, CLS) — Google's confirmed page-experience ranking signals since 2021

Security headers — HSTS, CSP, X-Frame-Options — protecting visitors and supporting search rankings

WCAG 2.1 AA accessibility — color contrast, alt text, keyboard navigation, and ARIA labels

Indexability audit — robots.txt, noindex tags, sitemap coverage, and canonical configuration

On-page content signals — heading hierarchy, internal link integrity, and image optimization

Website Health Audit FAQ

Quick answers about what the audit covers, how it works, and what happens next.

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.
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, full history, PDF export, and competitor comparison.
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 undetected.
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 a composite health score.
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.
Yes. The health checker works on any publicly accessible URL regardless of the CMS or platform, including WordPress, Shopify, Squarespace, Wix, Webflow, and custom stacks.
Paste any public URL into the checker, enter an email for the report, and run the scan. You get 3 free website health checks per day with no account and no credit card — the full four-pillar report (SEO, speed, security, accessibility) appears in your browser in about 30 seconds.
Yes. The health checker parses the HTML your server actually sends — title tags, meta descriptions, heading hierarchy, canonical tags, schema markup, image alt text, and robots directives — alongside the HTTP security headers and rendered-page performance that pure HTML SEO checkers miss.
A score of 85 or above means your SEO, performance, security, and accessibility signals are all fundamentally healthy. Anything below 70 usually indicates at least one Critical finding — a noindex leak, broken canonical, failing Core Web Vital, or missing security header — that should be fixed before anything else.
