How to Automate Website Health Checks: A Practical Checklist for Website Owners
Most websites are launched, admired and then ignored until something breaks. A website health check is the habit that prevents that: a short, repeatable set of checks that catches problems while they are still small — an expiring certificate, a page returning errors, a sitemap that quietly stopped working.
This guide covers what a health check should include, how often to run each part, which checks are worth automating and which still need a person. It is about the broader routine; for a single-purpose walkthrough of a specific check, we link to the relevant free tool along the way.
- A health check covers availability, security basics, discoverability and content integrity.
- Automate what is frequent, objective and time-critical (uptime, expiry dates); do the rest by hand on a schedule.
- Alerts should be actionable and rare — one message per real problem, with a named owner.
- Scans and automated checks have limits; they support, but don't replace, backups, updates and periodic human review.
What a website health check includes
A useful way to think about health is in four groups:
- Availability: is the site up, and fast enough?
- Trust and security basics: is the certificate valid, is the domain safe from lapsing, are there signs of unwanted code?
- Discoverability: can search engines find and understand your pages — sitemap, indexing, key technical SEO signals?
- Integrity: do links work, forms deliver, and has content changed unexpectedly?
Uptime and response time
Uptime is the most time-critical check, and the easiest to automate: a monitor requests your address every few minutes and alerts you when it fails and again when it recovers. Response time recorded by the same checks is a useful early hint — a site that gradually slows is often heading for trouble. It is only a hint: for real performance data, use a dedicated speed test.
Detail on how monitors avoid false alarms is in our guide to website downtime causes and monitoring. SiteBuddy automates this check with email alerts.
SSL and domain expiry
An expired certificate stops visitors with a full-screen browser warning; an expired domain takes the whole site and email offline. Both are entirely predictable, which makes them ideal for automation: set reminders well ahead of the date, and verify auto-renewal actually succeeded. You can inspect a certificate with the SSL checker, and check domain dates with the Whois checker. Make sure the renewal contact email is monitored by a real person.
Broken links
Broken internal links hurt visitors and waste search-engine attention; broken outbound links make content look neglected. A crawler can scan the whole site monthly and list them. The automated part is finding links; deciding what each should point to, or whether to remove it, is manual.
Sitemap availability
Your XML sitemap helps search engines find pages. Check that it loads, is valid, lists the URLs you want indexed and doesn't include pages that redirect or return errors. After a redesign or a plugin change, sitemaps are a classic silent failure. The sitemap checker tests a sitemap quickly; the routine task is remembering to check it.
Selected technical SEO checks
You don't need a full audit every week. A short recurring set is enough to catch accidents: robots.txt hasn't changed to block everything, no stray noindex tags, key pages return a normal status, titles and headings are still present, and canonical tags point to the right URLs. Run a fuller review, such as our free SEO audit, quarterly or after significant changes.
Website content changes
Change detection compares a page, or the list of scripts it loads, with an earlier version and flags differences. It can alert you to an accidental edit, a plugin that rewrote a template or code that appeared without anyone adding it. It generates noise on frequently updated pages, so apply it to stable ones — homepage, contact page, checkout — and expect to review what it flags.
Security scans and their limits
A public security scan can spot suspicious scripts, hidden iframes, injected links and missing security headers. It cannot see inside your server, so it is a smoke detector rather than a full inspection. Pair it with updates, strong passwords, backups and, where risk is high, server-side checks. Our explainer on what a malware scanner can detect covers the limits in detail, and SiteShield is our public-site scanner.
How often to run each check
| Check | Suggested frequency | Automate? |
|---|---|---|
| Uptime and response time | Every few minutes | Yes |
| SSL certificate validity | Daily or weekly; alert 30+ days before expiry | Yes |
| Domain expiry | Monthly; reminders 60+ days ahead | Yes (reminders) |
| Broken links | Monthly | Yes (crawl), manual fixes |
| Sitemap and robots.txt | Weekly or after any change | Mostly |
| Technical SEO spot-check | Monthly; full audit quarterly | Partly |
| Public security scan | Weekly or monthly, plus after changes | Yes |
| Form and checkout test | Weekly | Partly — a human should test end-to-end |
| Backups restore test | Quarterly | Manual |
| Updates (CMS, plugins, themes) | Weekly review | Partly |
Alerts and reports
- Send alerts to people who can act, and name an owner for each type of alert.
- Keep alerts rare. One message per real problem beats a stream people learn to ignore.
- Include context: what failed, since when, and where to look.
- Use a short monthly summary — uptime, issues found, issues fixed — so the health of the site is visible to the business, not only to technicians.
Automated versus manual checks
Automation is best for checks that are frequent, objective and time-sensitive. People are better at anything that needs judgement or a real journey: does the checkout complete, does the contact form reach someone, is the content still accurate and on-brand? A page can be up, valid and fast, and still be wrong. Schedule a short manual walkthrough of your most important journeys alongside the automated checks.
Building a practical maintenance routine
- Set up uptime monitoring with alerts to at least two people.
- Add SSL and domain expiry reminders, with owners.
- Schedule a monthly crawl for broken links and error pages.
- Check the sitemap and robots.txt after every significant change.
- Run a quarterly SEO and speed review.
- Run a public security scan weekly or monthly, and after plugin or theme changes.
- Test contact forms and checkout every week.
- Review updates and apply them with a backup in place.
- Test restoring a backup at least quarterly.
- Keep a simple log of issues, fixes and dates.
If you would rather not own this routine, an ongoing website maintenance contract bundles monitoring, updates and backups with a named team. Either way, the principle is the same: small, regular checks cost far less than a surprise outage.
Frequently asked questions
What is a website health check?
A recurring set of checks covering availability, security basics, search discoverability and content integrity, designed to catch problems early.
How often should I check my website's health?
Time-critical items such as uptime run continuously, while others run weekly, monthly or quarterly. The table above gives a starting schedule you can adjust to your risk.
Can I fully automate website maintenance?
No. Monitoring and scanning automate detection, but fixing issues, testing key journeys, applying updates safely and keeping backups still need people or a maintenance provider.
Do I need paid tools?
Not always. Free tools cover many one-off checks, and a free plan may be enough for a single site. Paid tiers matter when you manage several sites or need history and alerts.
What should I do first if I have no routine?
Set up uptime monitoring, put SSL and domain renewal dates in a shared calendar, and make sure you have a tested backup. Add the rest gradually.
Does a clean health check mean my site is secure?
No. It means the checks you ran found nothing. Public scans in particular have limits, so keep updates, backups and access controls in place.
