To maintain a WordPress site, you need to update core, themes and plugins, back up and test restores, scan for malware, monitor uptime, clean the database, fix broken links, review user accounts, check SSL and PHP, and test site speed. The latest WordPress 7.1.2 security release is a useful reminder. Released on 22 September 2026, it fixes a critical vulnerability that, under specific server and theme conditions, could let a hacker run their own code on your site without logging in. WordPress recommends updating affected sites immediately.

That is why WordPress maintenance should not be treated as an occasional clean-up job. From security updates and backups to performance checks and PHP versions, these 10 tasks help keep a WordPress site secure, reliable and ready for visitors.

1. Update WordPress Core Promptly

WordPress core updates can contain security fixes, bug fixes and improvements. When a security release arrives, delaying the update can leave a site exposed to a known vulnerability.

WordPress 7.1.2 is a recent example. The project specifically recommends updating sites immediately because it addresses a critical security issue. Make core updates part of your regular WordPress maintenance checklist, with testing in place for important ecommerce or business websites.

2. Update Themes and Plugins

WordPress core is only one part of your website. Themes and plugins can also introduce security vulnerabilities, compatibility problems or outdated code.

Review available updates regularly and remove plugins that are no longer needed. Before applying major changes to a live site, check compatibility and test key functions. For an ecommerce website, this includes product pages, checkout, payment integrations, forms and customer accounts.

3. How Often Should You Back Up WordPress?

Back up WordPress at least daily for ecommerce sites and weekly for brochure sites, using a tool like UpdraftPlus. A backup is only useful if you can restore it.

Do not stop at checking whether a backup completed successfully. Test the restoration process periodically. A tested recovery plan can save a lot of time when an update, configuration change or security incident causes an unexpected problem.

4. Run Malware Scans and Use a Firewall

Run a malware scan at least weekly with a tool like Wordfence or Sucuri, and use a web application firewall to block harmful requests.

These tools are not a substitute for keeping WordPress, themes and plugins updated. Think of them as another layer in your security process. If a scan reports something unusual, investigate it rather than simply dismissing the alert.

5. Monitor Website Uptime

A website cannot serve customers when it is unavailable. Uptime monitoring checks your site at regular intervals and alerts you when it becomes unreachable.

This is very useful for business and ecommerce websites, where an outage can affect enquiries, sales or customer trust. Ongoing website maintenance services include uptime checks as standard.

6. Clean and Optimise the Database

WordPress databases can accumulate unnecessary data over time. Revisions, expired transients, spam comments and other redundant records can increase database size without adding value to the live website.

Regular database maintenance can help keep things organised and reduce unnecessary overhead. However, database changes should be handled carefully. Always take a current backup before deleting or modifying database records, especially on a live ecommerce site.

7. Check for Broken Links and 404 Errors

Links can break when pages are deleted, URLs change or websites are reorganised. A growing collection of broken links can frustrate visitors and make it harder for them to reach important content.

Run regular checks for broken internal and external links. Review your 404 reports as well. Where a useful page has moved, consider implementing an appropriate redirect instead of leaving visitors at a dead end.

8. Review User Accounts and Login Security

Not every user who once needed access to a WordPress website still needs it today. Review administrator and editor accounts regularly, particularly when employees, freelancers or agencies stop working on the site.

Remove stale accounts and use strong, unique passwords. Two-factor authentication can add another layer of protection to administrator accounts. Also review user roles so people have only the permissions required for their work.

9. Why Should Your WordPress Site Run PHP 8.3 or Higher?

HTTPS should be treated as a basic requirement, not something you check only when a browser displays a warning. Confirm that your SSL certificate is valid and that HTTPS works correctly across the site.

Before changing PHP, test your themes, plugins and integrations for compatibility. If your site uses custom code, an experienced WordPress agency can test and fix it before you switch.

10. Test Site Speed and Core Web Vitals

Your website may work, but if it is slow to load, visitors will have a poor experience. Test your site speed every month so you can spot problems early.

Test your key templates across desktop and mobile. Check your Core Web Vitals (LCP, INP and CLS) and page size. Images, cache, scripts and hosting speed should all be monitored. If your site slows down after a change, check what was changed first.

Make These Tasks Part of a Regular Routine

Following this checklist helps in many ways. Regular security updates, backups and link checks stop small issues from turning into big ones.

If your website brings in leads or sales, regular WordPress maintenance and support protects that income.

FAQs

Check for plugin updates at least once a week and apply security updates straight away. Test routine updates on a staging site first where you can. Remove any plugins you no longer use or that are no longer supported.

No. WordPress is still updated often with new features and security fixes. The latest version, 7.1.2, was a security release on 22 September 2026. A WordPress site only becomes outdated when it is not maintained.

Start with backups, core and plugin updates, and security scans. These protect your site the most. Then add uptime checks, speed tests and link checks.
