Essential WordPress Maintenance Checklist

A website is not something that is cast in stone, as there are too many moving parts for it to just sit there like a double-page spread advertisement in a magazine, which is why making sure your website remains healthy is the most important thing you can do to improve its longevity which will save you time and money in the long term.

Why is website maintenance so important?

The most common perception around websites is that once it’s up and running, you just sit back and reap the benefits but nothing can be further from the truth. Essentially, if you do not maintain your website then you will forever be reacting to emergencies like being hacked, unnecessary spam, your site crashes, important pages not loading at all or a sudden loss of traffic to your site. This is stressful, expensive, and damaging to your brand.

Take WordPress as an example. It’s a widely used, well-supported platform with a huge global ecosystem behind it. More than a million developers contribute themes, plugins and tools, giving it one of the most extensive feature libraries of any CMS. With that scale comes remarkable flexibility, and the platform relies on regular updates to keep everything running at its best.

There are over 70,000 plugins, over 30,000 themes and countless other modification options to tailor a site on a platform that was designed to be extended. With that level of flexibility, it can be a highly complex beast, and one that constantly needs to be updated.

An average WordPress site has one theme and between 10 and 30 plugins installed … all from different developers, who are continually improving their products by adding functionality and fixing security holes. Apart from the functionality, the updating and securing of its code is a core discipline required for these developers to be able to operate in the WordPress ecosystem.

In WordPress, aside from applying these fixes (called updates), there are best practice disciplines that mirror those of standard IT systems with similar risk profiles operating in an identical manner. This takes the form of:

While this is a snapshot of the type of maintenance that is required to ensure your website runs smoothly, the reality of not being proactive with updates usually leads to visible issues. A site that isn’t updated can look outdated or function incorrectly, creating a poor experience for visitors, and that decline in quality can indirectly affect your SEO performance over time.

So what does maintaining your website entail?

Basically, all your plugins and themes require regular updates that protect your website from glitches or security vulnerabilities. One of the more common mistakes is not backing up your website’s data before any major updates. A backup is required so that, should anything go wrong, you can easily revert to the last backup and get your website up and running again. You can then initiate a proper fix that will align with current updates to your plugins and themes if needed.

For some websites that are smaller and do not have regular blog or product updates, it is advisable to do a backup before updating all your plugins and themes at least once a month. However, if you are dealing with high volume visitors and you are constantly updating content, then daily incremental backup is best practice to counter issues that compromise your website’s functionality.

Frequently Asked Questions about WordPress Maintenance

What’s the biggest misconception people have about website maintenance?

A lot of people see maintenance as optional or something you do once and forget about. In reality, it’s what keeps a site secure, fast and dependable. A website isn’t a static product; it often has updates that changes constantly, so it needs regular attention.

Without consistent updates, optimisation and security checks, even a small site can slow down, break or become vulnerable to attack. Proper maintenance isn’t about patching problems after the fact; it’s about preventing issues, protecting the site and keeping performance strong. It’s less of a “cost” and more of a safeguard against downtime, data loss and reputational damage.

Broken links, missing images, slow loading times, layouts that don’t work well on mobile, outdated content, old design elements such as dated social icons, and contact-form enquiries that arrive but never receive a reply are all signs that a site hasn’t been cared for in a while.

Most common failures can be avoided, including plugin conflicts, security breaches, broken layouts after updates, database bloat, poor performance, downtime caused by outdated software and slow degradation of user experience. Regular checks dramatically reduce these risks.

The first step is taking a complete backup before any significant update. After that, updates should be applied in a staging or testing environment where possible, so any conflicts can be identified and resolved before changes reach the live site.

Your website isn’t just a collection of files. It includes a database, core system files and a range of plugins and themes, all working together. With so many moving parts, there’s always a chance something could fail during an update. A recent backup allows you to restore the site quickly and protect your data, your business and your reputation.

PageSpeed Insights and Core Web Vitals are a good starting point. From there, you’d review server performance, plugin behaviour, caching, image optimisation and any recent changes that might have introduced delays.

WordPress core, themes and plugins are written and maintained by humans, so vulnerabilities are inevitably discovered over time. Developers release updates as soon as fixes are available. Keeping everything up to date significantly lowers the risk of someone exploiting an outdated component.

Reliable hosting improves uptime, provides secure and modern server environments and offers regular backups as part of the service. Good hosting reduces the amount of technical firefighting required. Poor-quality hosting can result in frequent outages, slow performance, weak security and data loss, all of which can harm SEO, increase bounce rates and undermine user trust.

Tools such as Broken Link Checker or Screaming Frog can scan a site for broken links and missing resources. Redirects should also be reviewed periodically to ensure they are still pointing to the correct destinations and haven’t been disrupted by structural changes.
