A website is not finished at launch. Software needs updates, content goes out of date, integrations change and new security threats appear. A website maintenance checklist turns that ongoing care into a routine so issues are caught early.

Why website maintenance matters

  • Security: outdated software is a common route for attacks.
  • Reliability: forms, bookings and integrations break silently.
  • Performance: sites slow down as content and scripts accumulate.
  • SEO: broken links, errors and outdated content hurt visibility.
  • Credibility: old information and broken features damage trust.

Website maintenance checklist: weekly tasks

  • ☐ Check uptime monitoring alerts and resolve incidents.
  • ☐ Apply security updates for the CMS, themes, plugins and dependencies (test first on staging where possible).
  • ☐ Confirm backups completed successfully.
  • ☐ Test key forms and booking flows; confirm leads arrive in the CRM and inbox.
  • ☐ Review Search Console for new errors or security issues.

Monthly tasks

  • ☐ Restore a backup to a test environment to verify it works.
  • ☐ Scan for broken links and fix or redirect them.
  • ☐ Review page speed for key templates; see Core Web Vitals optimization.
  • ☐ Check analytics and conversion tracking for anomalies.
  • ☐ Review user accounts and remove access for people who no longer need it.
  • ☐ Update outdated content such as prices, team details and contact information.

Quarterly tasks

  • ☐ Run a technical SEO crawl; see our technical SEO audit checklist.
  • ☐ Review plugins and integrations; remove anything unused.
  • ☐ Spot-check accessibility on key pages; see our accessibility checklist.
  • ☐ Review security headers, SSL configuration and firewall settings.
  • ☐ Audit third-party scripts in your tag manager.
  • ☐ Review top pages for content accuracy and refresh opportunities; see how to update old blog posts.

Annual tasks

  • ☐ Renew domain and SSL certificates (or confirm auto-renewal).
  • ☐ Review hosting performance and capacity.
  • ☐ Update legal pages (privacy policy, terms, cookie information).
  • ☐ Review the overall site structure and conversion paths.
  • ☐ Plan larger improvements for the year ahead.

Website security updates

Apply updates promptly, especially security releases. Use staging environments to test major updates before applying them to the live site. Limit plugins and extensions to those you actively need, and choose well-maintained ones. Enforce strong passwords and two-factor authentication for administrators.

Website backups

Follow a simple rule: multiple backups, stored in more than one location, including one off-site. Automate them, retain several versions and test restores regularly. A backup you have never restored is a hope, not a plan.

Uptime monitoring

Use an uptime monitoring service that checks key pages every few minutes and alerts the right person by email or messaging app. Monitor important flows such as contact forms where possible, not just the homepage.

Website maintenance plan: who does what

Example maintenance responsibilities

Document the plan, including contacts for emergencies and where credentials are stored securely.

Broken links and redirects

Broken links frustrate users and waste crawl effort. Use a crawler monthly to find them. Fix internal links directly, and redirect removed pages to the closest relevant page. Avoid redirect chains.

Maintenance for different platforms

Maintenance needs vary by platform. Self-hosted WordPress sites need the most attention: core, theme and plugin updates, security hardening and backups. Hosted platforms such as Webflow or website builders handle infrastructure updates, so maintenance focuses on content, integrations, forms, SEO and performance. Custom-built sites need dependency updates, server patching and monitoring defined in a support agreement. Whatever the platform, form testing, tracking checks and content reviews remain your responsibility.

Maintenance and growth

Maintenance is not only about preventing problems. Use monthly reviews to identify improvements: pages that could convert better, content that needs updating and new questions customers ask. Small, continuous improvements keep a website effective between redesigns.
