Website Health Check: 12 Technical Problems to Catch Before They Hurt Traffic
A practical website health checklist covering HTTP status, HTTPS, response time, canonical tags, robots, sitemap, schema and broken internal links.
Small technical problems can quietly damage usability and discoverability long before anyone notices a dramatic outage. A lightweight health check helps catch obvious failures early: bad status codes, slow responses, broken internal links, missing discovery files and conflicting metadata.
The 12 checks worth doing regularly
You do not need a huge enterprise crawler for a basic health pass. Start with the signals that reveal common failures.
- Homepage returns a successful HTTP status.
- HTTPS works without certificate warnings.
- Redirects resolve to the intended canonical URL.
- Server response time is reasonable.
- Title and meta description exist.
- A clear H1 exists.
- Canonical points to the intended page.
- No accidental noindex is present.
- robots.txt is reachable.
- sitemap.xml is reachable.
- Structured data is present when relevant.
- A sample of internal links does not return errors.
Prioritize failures, not cosmetic warnings
A 404 on an important internal link, an unintended noindex or a broken HTTPS redirect deserves attention before a slightly short meta description. Group findings into critical, recommended and passed checks so the report turns into an action list.
Use a bounded crawl
A free health checker should sample internal links instead of trying to crawl thousands of pages. For a large site, use the sample to identify patterns, then run a dedicated crawler if the problem appears widespread.
Quick workflow
- Run the Site Health Checker on the homepage or an important landing page.
- Fix status, HTTPS and indexability issues first.
- Review broken-link samples.
- Check robots.txt and sitemap consistency.
- Repeat the scan after deployment.
FAQ
How often should I run a website health check?
Run one after significant deployments and periodically on important pages.
Does a good score guarantee SEO performance?
No. It only indicates that the checked technical signals are in reasonable shape.
Can one-page scanning find every broken link?
No. A bounded scan is useful for quick detection, not a replacement for a full site crawl.
Bottom line
The goal of a health check is to catch preventable technical failures early and turn them into a short repair list. Open Site Health Checker.
