As of 2025, WordPress powers over 43% of all websites on the internet, making it the most popular content management system (CMS) globally. But that popularity also makes it a prime target for cybercriminals.
And before you think, “That won’t happen to me,” remember that over 95% of WordPress security breaches happen due to outdated plugins and themes. Let that sink in!
So if you’re serious about your website, whether it’s a business, blog, online store or something else, you need a rock-solid maintenance plan.
In this article, we’ll be going over 10 comprehensive, in-depth, detailed-to-the-bone WordPress maintenance tips that every site owner in Australia and all over the world should know.
Keep All WordPress Core, Themes and Plugins Updated
Failing to update your site regularly can be detrimental. Skipping updates is like leaving your front door wide open, except it’s your website and there are bots constantly looking for unlocked doors.
WordPress regularly releases updates to fix bugs, patch security issues, and improve performance. You just have to check for updates once a week. If necessary, you can set a reminder every Monday.
You can let WordPress handle minor updates automatically (especially for trusted plugins), but always take a backup before you update anything. One click can sometimes break your layout or cause plugin conflicts.
If you’re running a large or custom-coded site, don’t test updates directly on your live site. Set up a staging environment or use a local version first. That way, you catch problems before they go public. And if your site is complex or mission-critical, you should actually consider getting help from a website design company in Sydney. It’ll save you headaches down the track.
- Automate and Test Backups
Your sites backup are your safety nets, and in most cases, they’re typically the only way to undo a disaster. In the event that your websites break, plugins clash, hackers strike, or perhaps a developer made a mistake, you’ll be one bad click away from starting over if there are no backups to fall back on.
There are two ways to handle backups. One is the old-school manual method, downloading your site files through FTP and exporting the database. This works, yes, but it’s time-consuming and easy to mess up. The better option is automation. Tools like UpdraftPlus, BlogVault or host-based backups from services like Kinsta let you schedule daily backups without lifting a finger.
You can’t afford to rely on a backup that’s days or weeks old. These could leave out crucial recent data, like new user sign-ups or updated product listings. Having a fresh backup means you’re prepared for any unexpected downtime, whether due to a server crash or a plugin conflict.
You should also consider storing your backups off-site using services like Google Drive, Dropbox, or Amazon S3.
- Lock Down Website Security
Use strong, unique passwords. Add two-factor authentication (2FA) while you’re at it. Apps like Google Authenticator or Authy make your login secure.
Install a security plugin to scan for malware, block known threats, and alert you when something looks off. Also, you should limit login attempts to stop bots in their tracks, and always use HTTPS. SSL certificates are free with most Australian hosting providers, and they keep your visitors’ data safe.
- Clear Out Old Plugins, Themes and Files
Most WordPress sites have clutter, which usually consists of plugins that were installed “just to try,” themes you never activated, and media files no one’s using anymore. Most people ignore these under the insinuation that they’re just harmless space takers. But in reality, they’re actually vulnerable spots.
You don’t want to have any of those on your website, so what you want to do is start with your plugins. If something’s deactivated and you’re not planning to use it again, delete it. The same goes for old themes. Keep the one you’re using and maybe one fallback like the latest default WordPress theme.
Your media library could probably use a cleanout too. And don’t forget about old backups, log files, and temp files sitting on server.
- Boost Your Site’s Speed and Performance
People won’t wait for a slow site, especially not Australians using mobile data on the go. If your pages take more than 3 seconds to load, expect visitors to bounce and rankings to drop.
Here are a few ways you can do this:
- Caching: If your host supports it, you should use a plugin that stores static versions of your pages and serve them up instantly.
- Tackle your images. Resize them to appropriate dimensions and compress them using tools like ShortPixel or TinyPNG.
- Serve your content faster by using a CDN: Use a content delivery network (CDN) to serve content from servers close to your visitors. This reduces latency, especially for global traffic.
- Minify your CSS, JavaScript and HTML: Most caching plugins offer this as a built-in feature. And enable lazy loading so images below the fold only load when a user scrolls down.
- Test the speed: Test your site speed regularly with tools like PageSpeed Insights or GTmetrix and don’t forget to test from different locations.
- Scan for Malware Weekly
Just because website looks okay doesn’t mean it is ok. Malware can sit quietly in your site’s files or database, doing damage behind the scenes. You might not notice until your host suspends your site or Google flags it.
The website design company you work with will help you run a full malware scan every week. They’ll check for suspicious code, altered files, and other signs of compromise.
If something’s detected, they’ll proceed to quarantine the infected file, restore from a clean backup, or reach out to a malware removal service for help. The best thing about early detection is that it makes for easier recovery or resolution.
- Keep an Eye on Uptime and Broken Links
Your website should be online all the time, but then several factors and occurrences might hinder this. Problems with hosting, failed updates, even expired domains can take your site offline without warning.
To prevent any of these from being an issue, you could set up uptime monitoring to check your site every few minutes and alert you if something goes wrong.
Also, don’t forget about broken links. They kill user experience and hurt your SEO.
- Test Changes on a Local WordPress Installation
Never test new plugins, themes or big changes on your live site. That’s basically asking for trouble. One bad line of code can take your site down completely.
Instead, what you should do is create a local version of your site, then test your changes there while working offline. You should only push to staging or live when you’re confident that everything works. This gives you a safe environment to experiment and prevents downtime for your visitors.
- Clean and Optimise Database
Your WordPress database holds everything, starting from your posts, pages, plugin settings, user data, and even spam comments. Over time, it gets bloated with junk you don’t need.
Run a database cleanup once a month using WP plugins such as WP-Optimize, WP Sweep or Advanced Database Cleaner.
They also optimise the database tables themselves, which can improve performance across the board. In the physical sense, this can be equated to tidying up your cabinet for a decluttered look.
- Use a Web Application Firewall (WAF)
If you’re not already using a Web Application Firewall (WAF), you’re essentially leaving your website vulnerable to a whole bunch of attacks that could have been blocked before they even hit your server.
A WAF sits between your website and the internet, filtering traffic and determining whether each request is legitimate or not. If someone tries to brute-force their way into your admin panel, or if a bot is scraping your content or trying to overload your server, the WAF steps in, intercepts that malicious traffic, and doesn’t let it anywhere near your site.
In more technical terms, WAFs inspect incoming HTTP/HTTPS requests and can block things like SQL injection, cross-site scripting (XSS), and even file inclusion attacks, all of which are common tactics that hackers use to compromise websites.
WAF’ best feature is that they are proactive, not reactive. While an antivirus program may clean up your site after a breach, a WAF blocks threats before they ever get the chance to make a mess. This is particularly important if you’re running a site that handles sensitive data, user logins, or any kind of transaction.
