WordPress Website Maintenance Checklist: 20 Things to Check Every Quarter!

WordPress Website Maintenance Checklist

Regular WordPress website maintenance ensures your site is secure & functional. However, it is also essential to offer visitors an optimal user experience. Especially between website redesigns, if not checked, security can collapse. Most of the time, you won’t see it coming.

Hence, you need this WordPress maintenance checklist that includes all 20 things that are worth reviewing during the quarterly website maintenance plan, from login security to backup integrity to page speed.

You need to work through this list every three months. It will help site owners catch small issues before they face downtime, lose rankings, or have a compromised site. So, it is important to understand why regular WordPress maintenance matters for optimum website performance.

Security Checks

In any WordPress security audit, the first thing to evaluate is security, since a breach will simply undo every other effort made towards maintenance.

1. SSL Certificate: Make sure to check the SSL certificate validity. Look at the expiry date and renewal settings. An expired certificate triggers browser warnings and drives visitors away fast.

2. Admin Passwords: Evaluate the age of the admin password. Any password older than 90 days should be rotated. Especially for accounts with full admin access.

3. User Access: Keep auditing the user role & their access from time to time. Revoke the access given to – old employees or freelancers. Check whether the existing users are holding the right roles.

4. Security Scan Logs: Review the latest malware & file-change scan results. Don’t assume that the plugin will run silently in the background.

5. Failed Login Monitoring: When multiple failed attempts are made through unfamiliar IP addresses – it tends to signal that a brute-force attack is in progress.

These steps align with the core WordPress security practices & also with Google Search Central’s guidance on site security issues. This flags potential ‘hacked content’ warnings directly in the Search Console.

Backup & Update Checks

Having a backup ready can damage-control a major disaster. It turns them into merely a minor inconvenience. Hence, at this stage, your mandatory WordPress maintenance checklist deserves thorough attention and not just a quick glance at a dashboard.

6. Backup Restoration Test: You need to ensure that your last backup actually gets restored, not just that it ran without errors.

7. Backup Storage Location: Make sure that you’ve stored the copies off the server. Ideally, it should be in two different locations, following WordPress.org’s official backup documentation.

8. WordPress Core Updates: It is critical to apply the pending core updates right after backing up. This is because the outdated core files remain a common entry point for attackers.

9. Plugin and Theme Updates: You need to update each one of them separately. Also, look out for any potential compatibility warnings in the way

10. Staging Site Tests: Test major updates on a staging copy before pushing them to the live site.

Performance and Uptime Checks

Slow and lagging websites tend to lose visitors easily, and also their search rankings. It makes this particular section essential to any WordPress health check.

11. Page Speed Test Score: You should use a speed testing tool to run the homepage and all the important landing pages. Then, you can easily compare the results against last quarter.

12. Image File Sizes: All the oversized images. Especially, the ones that were uploaded without optimization – should be compressed.

13. Review the Uptime Log: It is essential to scan the hosting or monitoring service’s uptime log for – recurring outages or slow response times.

14. Database Cleanup: Ensure you clean up the database after revisions. Also, remove any expired transients that just keep bloating the database over time.

15. 404 Error Checks: Keep checking for 404 errors. Ensure they are fixed, or broken pages are redirected, especially the ones that visitors and search engines are still hitting.

Content & SEO Checks: The Final Piece of Your WordPress Maintenance Checklist

This particular section of a WordPress site audit helps you check that your content is accessible to search engines and that they can trust the content.

16. Broken Links: Scan internal & external links for – anything returning a 404 or a redirect loop.

17. Meta Tags: Detect if you see any gaps in meta tags. Fill in missing or duplicate meta tags on the important webpages.

18. XML Sitemap: The XML sitemap must be submitted. And also updated after making changes in the site structure. Ensure the sitemap is updated in the Search Console.

19. Search Console Errors: Check Search Console coverage errors. Then, review the flagged indexing issues. Make sure to resolve them before they spread.

20. Analytics Tracking: Check the analytics tracking. You need to verify whether the tracking code still fires properly on every page template.
