Discover five practical WordPress tricks that can make your website faster, safer, easier to manage, and more reliable. From limiting post revisions to protecting the login page and optimizing images, these simple improvements can help beginners and experienced WordPress administrators maintain a healthier website.
1. Limit WordPress Post Revisions
WordPress automatically saves revisions whenever you edit a post or page. This feature is useful because you can restore an earlier version after making a mistake. However, websites with hundreds or thousands of posts may accumulate a large number of revisions over time. You can limit them by adding define( 'WP_POST_REVISIONS', 5 ); to wp-config.php before the line that tells you to stop editing. WordPress will then keep a maximum of five revisions for each post. Before modifying wp-config.php, always create a backup. Also remember that deleting existing old revisions requires a separate database cleanup; adding this constant mainly controls revisions created going forward.
2. Protect the WordPress Login Page
Every standard WordPress installation includes wp-login.php, which makes the login system an obvious target for automated password attempts. You do not necessarily need to hide the login URL to stay secure. A stronger approach combines unique passwords, two-factor authentication, limited login attempts, regular updates, and properly managed administrator accounts. Avoid using predictable administrator usernames when creating new accounts, and remove accounts that are no longer required. If your security plugin supports rate limiting or CAPTCHA protection, enable these features carefully. Cloudflare or another properly configured firewall can provide an additional layer against abusive traffic. These measures do not make a website impossible to attack, but they significantly reduce unnecessary exposure while keeping legitimate administrator access manageable.
3. Disable XML-RPC When You Do Not Need It
XML-RPC provides a way for external applications and services to communicate with WordPress. Some websites still need it, so disabling it blindly is not always appropriate. If your site does not depend on XML-RPC integrations, remote publishing tools, or another service that explicitly requires the feature, you can consider restricting or disabling it. A simple WordPress filter is add_filter( 'xmlrpc_enabled', '__return_false' );, although administrators should test their integrations afterward. Security plugins and server-level tools can also restrict unwanted XML-RPC requests. This trick is especially useful when your logs show repeated requests to xmlrpc.php. Keep in mind that disabling one interface does not replace strong passwords, two-factor authentication, updates, backups, and other basic WordPress security practices.
4. Optimize Images Before Uploading Them
Large images are one of the easiest ways to make a WordPress website unnecessarily slow. Uploading a 5 MB photograph and displaying it at only 800 pixels wide wastes bandwidth and can negatively affect the visitor experience. Resize images to dimensions appropriate for your design before uploading them, and use modern formats such as WebP or AVIF when your workflow and browser requirements allow it. WordPress already creates several image sizes and supports responsive image markup, so avoid plugins or custom code that interfere with these features without a clear reason. Lazy loading is useful for images farther down the page, while the main above-the-fold image may need different treatment. Good image optimization can reduce page weight and help improve loading performance without noticeably reducing visual quality.
5. Use a Child Theme or MU-Plugin for Custom Code
Adding PHP modifications directly to a parent theme’s functions.php file can create maintenance problems because a theme update may overwrite your changes. A child theme provides a safer location for modifications that belong specifically to your site’s design. For functionality that should remain independent of the active theme, a small custom plugin or WordPress MU-plugin can be an even better solution. MU-plugins stored inside wp-content/mu-plugins/ load automatically and cannot be accidentally disabled through the normal Plugins screen. This makes them useful for carefully tested site-specific functionality. However, PHP errors in custom code can still break a website, so test changes on staging and keep a recent backup. Separating functionality from presentation also makes future troubleshooting and theme changes considerably easier.

Frequently Asked Questions
Are these WordPress tricks suitable for beginners?
Yes. Most of these improvements are suitable for beginners, although changes involving PHP or wp-config.php should always be backed up and tested carefully.
Should I disable XML-RPC on every WordPress website?
No. Disable or restrict it only when you are confident that your website and connected services do not require it.
How many WordPress revisions should I keep?
Five to ten revisions can be a reasonable starting point for many blogs. Sites with editorial workflows may benefit from keeping more.
Is hiding wp-login.php enough to secure WordPress?
No. Changing or hiding the login URL can reduce automated noise, but strong passwords, two-factor authentication, updates, and access controls are more important.
Should I use WebP or AVIF images?
Both formats can substantially reduce image sizes. WebP offers broad compatibility, while AVIF can provide excellent compression when supported by your workflow.
What is the difference between a child theme and an MU-plugin?
A child theme is appropriate for theme-related customizations. An MU-plugin is generally better for functionality that should continue working independently of the active theme.
Can too many plugins slow down WordPress?
They can, but the number alone does not determine performance. One poorly designed plugin can cause more problems than several lightweight, well-coded plugins.
Do I need a caching plugin?
Many WordPress websites benefit from page caching. However, the best configuration depends on your hosting environment, server cache, CDN, and existing optimization tools.
Should I make a backup before editing WordPress files?
Yes. Keep a recent database and file backup before modifying PHP files, wp-config.php, plugins, themes, or important server settings.
Small Changes Can Make a Big WordPress Difference
The best WordPress tricks are often simple improvements rather than complicated optimization techniques. Controlling revisions keeps unnecessary database growth manageable, sensible login protection reduces exposure, and restricting unused functionality can decrease the attack surface. Properly optimized images improve the visitor experience, while child themes and MU-plugins provide cleaner ways to maintain custom code. Apply these changes individually, test the website after each modification, and avoid installing unnecessary optimization tools simply because they promise instant results. A fast and secure WordPress website usually comes from regular maintenance, sensible configuration, reliable backups, and careful testing rather than a single plugin or hidden trick.
