A WordPress maintenance checklist is the simplest way to stop small problems becoming emergencies: back up your site, update WordPress core, themes and plugins, scan for malware, and check speed and broken links every month. Most of these 12 tasks take under an hour a month combined — and skipping them is how sites get hacked, slow down, and lose Google rankings.
WordPress powers over 40% of the web, which also makes it the most-targeted platform for attackers. Maintenance is not optional housekeeping; it is what keeps your site online, trusted, and competitive.
1. Back Up Your Entire Site
Before touching anything else, confirm you have a recent, restorable backup — files plus database — stored off your server (cloud storage or a separate backup service). Test a restore at least once: a backup you have never restored is a hope, not a plan. Daily backups suit busy or e-commerce sites; weekly backups suit quiet brochure sites.
2. Update WordPress Core, Themes, and Plugins
Outdated software is the top cause of WordPress hacks. Update core first, then themes, then plugins — and always back up before updating. Delete inactive themes and plugins entirely: unused code is still an attack surface. If an update breaks something, roll back from your backup rather than leaving the site half-updated.
3. Run a Security Scan
Run a malware and vulnerability scan monthly (and after any incident). Check for unknown admin users, unexpected files, and changed core files. A security plugin with a firewall adds a useful layer, but it does not replace updates and strong passwords.
4. Review Users and Passwords
Remove old staff, freelancer, and test accounts. Every admin should use a unique, strong password and two-factor authentication. Fewer admins means fewer ways in.
5. Check Your Site Speed
Test your homepage and key landing pages with a speed tool each month. A site that loads in over 3 seconds loses visitors and rankings. Common fixes: image compression, caching, removing heavy plugins, and quality hosting. Track the score monthly so gradual slowdowns do not creep past you.
6. Fix Broken Links and 404 Errors
Broken links frustrate visitors and waste crawl budget. Scan monthly, fix internal links, and redirect deleted pages to the closest live page instead of leaving dead ends.
7. Clean Up the Database
Revisions, spam comments, trashed posts, and expired transients bloat the database over time. A monthly cleanup keeps the admin fast and backups smaller. Always back up before optimising the database.
8. Moderate Comments and Spam
Spam comments hurt trust and can carry malicious links. Review the queue monthly, tighten comment settings, and delete anything that adds no value. If you get no genuine comments, consider closing comments on pages where they serve no purpose.
9. Check Forms, Checkout, and Key Pages
Submit your own contact form, test any booking or checkout flow, and open your top 5 pages on mobile. Businesses lose leads silently when a form breaks after an update and nobody notices for weeks.
10. Review SEO Basics
Confirm titles, meta descriptions, and headings are still in place after updates, check that your sitemap loads, and glance at Search Console for new errors or coverage problems. A theme or plugin update can quietly break SEO settings.
11. Renew Domains, Hosting, and Licences
Put domain, hosting, SSL, and premium plugin renewals on a calendar with reminders. Losing a domain or letting SSL lapse takes a site offline and damages trust instantly.
12. Review Analytics and Uptime
Check traffic, top pages, and uptime for the month. A traffic drop often signals a technical problem — a broken page, a speed regression, or a de-indexing issue — and catching it monthly limits the damage.
How Often Should You Do WordPress Maintenance?
Weekly for backups and updates on active sites; monthly for the full checklist above; quarterly for a deeper review of hosting, design, and content performance. A maintenance plan from an agency typically costs $50–$300 per month — cheap insurance against a hack recovery that can cost thousands and take your site offline for days.
Frequently Asked Questions
How often should WordPress be updated?
Check for updates weekly and apply them promptly after a backup. Security releases should never wait for a monthly cycle — apply them as soon as they are available.
What happens if I never maintain my WordPress site?
It slows down, accumulates security holes, and eventually breaks or gets hacked. Recovery usually costs far more than a year of routine maintenance, and lost rankings can take months to regain.
Can I do WordPress maintenance myself?
Yes, if you are comfortable with backups, updates, and basic troubleshooting — this checklist covers it. If updates make you nervous or your site earns revenue, a professional maintenance plan is worth it.
Do I need a maintenance plugin?
Plugins help with backups, security scans, and optimisation, but they do not replace the checklist: someone still has to review results, test forms, and act on warnings. Tools assist maintenance; they are not maintenance.
