Building a WordPress website isn’t really the end of the job. Like any piece of software, a website needs ongoing attention to keep it secure, reliable and working as it should.

WordPress itself is regularly updated, as are the plugins and themes that add functionality to your website. Hosting technology changes, security threats evolve and, occasionally, things simply stop working as expected.

The good news is that WordPress maintenance doesn’t need to be complicated.

This WordPress website maintenance checklist covers the main things that should be looked after and why ongoing maintenance matters.

Why does a WordPress website need maintenance?

A modern WordPress website is made up of several different components working together.

There’s WordPress itself, your theme, plugins, hosting environment, database, SSL certificate and any third-party services connected to the site. Contact forms, payment systems, booking platforms and other integrations can add another layer.

Keeping these components maintained helps your website remain:

• Secure and protected against common vulnerabilities
• Fast and reliable
• Compatible with current browsers and devices
• Properly backed up
• Less likely to suffer unexpected errors
• Easier to repair if something does go wrong

Good maintenance also protects the investment you’ve already made in professional web design and WordPress design & development. There’s little point building a good website and then leaving the underlying software untouched for the next five years.

The WordPress maintenance checklist

1. Keep WordPress core updated

WordPress regularly releases updates containing new features, bug fixes, compatibility improvements and important security patches.

Minor security and maintenance releases can often be applied automatically, while major WordPress updates may deserve a little more attention.

Important updates shouldn’t simply be left waiting indefinitely. Before significant changes are made, there should also be a recent working backup available should anything go wrong.

When? As updates become available, with important security updates applied promptly.

2. Update WordPress plugins

Plugins are one of WordPress’s greatest strengths, but they’re also one of the main reasons ongoing maintenance is important.

Developers regularly release updates to improve security, fix bugs and maintain compatibility with newer versions of WordPress and PHP.

Leaving plugins outdated for long periods can increase the risk of security vulnerabilities or compatibility problems.

Updates should ideally be followed by a check of the website rather than simply clicking ‘Update All’ and hoping for the best.

When? Regularly, as appropriate updates become available.

3. Keep your WordPress theme updated

Your WordPress theme should also be kept current.

Theme updates can contain security fixes, performance improvements and compatibility changes. This is particularly important when your theme works closely with a page builder or block system.

If your website uses a child theme or contains custom development, extra care may be needed when applying major theme updates.

When? As appropriate theme updates become available.

4. Check the website after updates

Installing updates is only half the job.

Once WordPress, a theme or plugins have been updated, important areas of the website should be checked to make sure everything still works.

That includes key pages, navigation, forms and any important interactive functionality.

For more complex websites this might include:

• Online shops and checkout processes
• Booking systems
• Membership areas
• Property listings
• Search and filtering
• Payment gateways
• Third-party integrations

A successful update message doesn’t necessarily mean everything on the front end is working perfectly.

When? Following significant WordPress, plugin or theme updates.

5. Maintain regular website backups

Every WordPress website should have regular backups.

A good backup gives you a route back if an update causes a problem, the website becomes corrupted, something is accidentally deleted or the site is compromised.

WordPress Backups should include both the website files and its database.

For most business websites, automated daily backups provide a sensible level of protection, particularly for websites receiving enquiries, orders, bookings or regular changes.

When? Automatically and regularly – ideally daily for a business website.

6. Keep a separate or offline backup

There’s an important distinction between having backups and having backups that aren’t all stored in the same place.

If your only backups are held within your hosting account, a serious hosting or account problem could potentially affect both the website and the backups you need to restore it.

Keeping a separate backup provides another layer of protection.

It’s the digital equivalent of not keeping your spare house key inside the house.

When? As part of the website’s regular backup routine, alongside hosting-level backups.

7. Monitor website security

WordPress security isn’t about installing one security plugin and forgetting about it.

Ongoing security monitoring can help identify suspicious activity, malicious files, unusual login attempts and known vulnerabilities.

Administrator accounts should use secure passwords, unnecessary accounts should be removed and access to the website should be limited appropriately.

Security is also one of the reasons keeping WordPress, plugins and themes updated matters. Vulnerabilities can become publicly known, making websites running outdated software an easier target.

When? Continuously where automated monitoring is available, with action taken when issues are detected.

8. Check your SSL certificate

Your website should load securely over HTTPS and display a valid SSL certificate.

Most good hosting providers now automatically renew SSL certificates, but it’s still worth making sure everything is working correctly.

An expired or incorrectly configured SSL certificate can result in browser security warnings – not exactly the reassuring welcome you want to give a potential customer.

When? Automatically monitored where possible, with any certificate problems dealt with promptly.

9. Test your contact forms

One of the simplest maintenance jobs is also one of the easiest to overlook.

Fill in your own contact form.

A form can appear to work perfectly on the website while its notification emails fail to arrive. Changes to email authentication, hosting settings, plugins or third-party services can all affect delivery.

A business website quietly losing enquiries is considerably worse than discovering the problem during a routine check.

Testing is particularly important after changes to WordPress, form plugins, SMTP configuration, DNS or email services.

When? Regularly and after relevant website or email configuration changes.

10. Monitor website speed & performance

Websites can gradually become slower over time.

New plugins, larger images, additional scripts, tracking tools and database growth can all have an effect.

Performance should therefore be monitored and any noticeable deterioration investigated.

That doesn’t mean obsessing over achieving a perfect performance score. The goal is a website that loads quickly and feels responsive for real visitors.

When? As part of ongoing website monitoring and after significant technical changes.

11. Check for broken links and 404 errors

Pages are deleted, URLs change and external websites disappear.

Over time this can leave your website with broken links or visitors arriving at pages that no longer exist.

Internal broken links should be corrected and old URLs redirected where appropriate.

Google Search Console can also help identify indexing problems and unexpected 404 errors that may need attention.

When? Monitored as part of ongoing website maintenance and whenever website structure or URLs change.

12. Keep PHP and hosting software current

WordPress runs on PHP, and PHP versions themselves eventually reach the end of their supported life.

Using an outdated version can create security, performance and compatibility problems.

Your hosting provider will normally manage the underlying server environment, but the PHP version used by your WordPress installation is still important.

Don’t simply switch to the newest PHP version without checking that WordPress, your theme and plugins support it.

When? As hosting technology changes and supported PHP versions are updated.

13. Remove unused plugins and themes

Inactive plugins and old themes don’t need to sit on your website indefinitely.

If something is no longer required, removing it reduces clutter and reduces the number of components that need monitoring and maintaining.

Keep the active theme and any required parent theme, but redundant plugins and abandoned themes should be removed rather than forgotten about.

It’s also worth questioning whether a plugin is still needed before replacing it with yet another plugin. WordPress websites have a habit of accumulating them if nobody is keeping an eye on things.

When? As part of ongoing maintenance whenever plugins or themes become redundant.

14. Review WordPress users & administrator access

Businesses change. Staff leave, developers finish projects and people who once needed access to the website may no longer need it.

WordPress users should therefore be checked and accounts that are no longer required removed.

Users should also have an appropriate role. Not everyone who needs to edit a page needs full Administrator access.

This helps reduce unnecessary access to important website settings and limits the potential impact of a compromised user account.

When? Whenever access requirements change and as part of regular security checks.

15. Check the website on mobile

Your website may not have changed dramatically, but browsers, devices, plugins and the way individual elements behave certainly can.

Important areas of the website should therefore occasionally be checked on actual mobile devices as part of ongoing testing.

Pay particular attention to menus, buttons, forms, pop-ups and interactive elements.

Responsive web design should make a website adapt across different screen sizes, but software updates and technical changes can occasionally introduce problems that weren’t there when the site was originally built.

When? Following significant website changes and as part of ongoing front-end checks.

WordPress maintenance isn’t a once-a-month job

Website maintenance is better thought of as an ongoing process rather than a checklist that’s worked through once every few months.

Some tasks can be automated and monitored continuously, while others need to be carried out when WordPress, plugin or theme updates become available. Backups should run automatically, security should be monitored and important updates shouldn’t be left waiting simply because the next scheduled maintenance date hasn’t arrived yet.

A well-maintained WordPress website should typically include:

Not every task needs to happen every day, but maintenance itself should be ongoing.

Problems are generally easier to deal with when they’re spotted early rather than several months after they first appeared.

WordPress maintenance should look after the website, not just update it

It’s easy to think of WordPress maintenance as simply logging in and clicking the update buttons.

Updates are certainly an important part of it, but proper website care goes further.

The aim is to make sure the website remains secure, backed up and technically healthy – and that it continues to work properly after changes have been made.

That distinction matters.

A plugin can report that it updated successfully while a form, layout or piece of functionality has stopped working elsewhere on the website. Likewise, an automated backup isn’t much use if it isn’t available when something needs to be restored.

Good WordPress maintenance combines automation with regular oversight.

Can WordPress maintenance be automated?

Quite a lot of it can.

WordPress can automatically install certain updates, hosting platforms can create automatic backups and security software can continuously monitor websites for potential problems.

Automation is useful, but it isn’t quite the same as website maintenance.

An automatic update knows whether an update installed successfully. It doesn’t necessarily know that your contact form has stopped sending emails, the mobile menu looks peculiar or the checkout page has suddenly developed ideas of its own.

Automated systems are excellent at carrying out repetitive tasks and flagging potential problems. A person is considerably better at deciding whether the website is actually behaving itself.

The best approach combines sensible automation with somebody making sure the website remains healthy and working properly.

Can I maintain my own WordPress website?

Absolutely.

If you’re comfortable using WordPress and prepared to keep on top of updates, backups, security and technical checks, there’s no reason a small business owner can’t maintain their own website.

The difficulty tends not to be knowing where the update button is.

It’s keeping an eye on everything consistently – and knowing what to do if an update causes a problem.

You also need to be confident that you can restore the website from a backup if necessary rather than discovering how the process works when the website is already broken.

For some businesses, managing the website themselves makes perfect sense.

For others, handing the technical side over means they can concentrate on running the business instead.
