The Complete WordPress Maintenance Checklist for 2026

A WordPress website is never “finished.” Core, themes and plugins release updates constantly, and every unpatched plugin is a potential entry point for hackers. Regular maintenance keeps your site secure, fast and reliable — and it is far cheaper than recovering from a hack.

Here is the checklist we use for our WordPress maintenance clients.

Weekly tasks

• Back up files and the database, and store copies off-server.
• Update plugins and themes — test major updates on staging first.
• Check uptime reports and fix any downtime causes.
• Review security scan results and failed-login alerts.
• Delete spam comments and form submissions.

Monthly tasks

• Update WordPress core (minor releases auto-update; plan major ones).
• Test a backup restore — a backup you have never restored is just a hope.
• Run a speed test on key pages and compare with last month.
• Scan for broken links and fix 404 errors.
• Review user accounts and remove anyone who no longer needs access.
• Test contact forms and checkout flows end to end.

Quarterly tasks

• Audit plugins: remove inactive or abandoned ones, and replace any not updated in a year.
• Optimise the database: clear revisions, transients and orphaned data.
• Check PHP version — run a supported version for both security and speed.
• Review Search Console for crawl errors, Core Web Vitals and security issues.
• Refresh key content — update outdated stats, pricing and screenshots.

Yearly tasks

• Renew the domain, SSL certificate and premium licences.
• Review hosting performance and costs.
• Run an accessibility check against WCAG guidelines.
• Revisit design and messaging — does the site still reflect your business?

Security essentials for 2026

• Two-factor authentication for all admin users.
• A web application firewall (WAF).
• Limited login attempts and strong, unique passwords.
• File permissions locked down and file editing disabled in the dashboard.

Prefer to hand it off?
