7 WordPress maintenance tasks you should perform on a regular basis

Update WordPressWordPress is a simple, yet feature rich platform. Although it has a small learning curve (like any new application), it is pretty easy to get a site up and running. There are tons of free themes and plugins that make it easy for even a website novice to develop a fully functioning WordPress website or blog. But, like anything, it requires the occasional tuneup in order to continue running optimally. Even the fanciest luxury vehicle needs to go to the shop every once and a while.

The following seven tasks should be performed on a regular basis to ensure your WordPress website continues running smoothly and securely.

1. Update WordPress

Since it’s inception, WordPress has blossomed from a simple blogging application into a fully blown Content Management System (CMS). It’s used to power some of the most popular websites in the world, including Forbes, Best Buy and Jay Z. It seems that each new release brings new features and enhancements that make the application better and better. However, the growing popularity of WordPress websites is also the application’s biggest vulnerability, as it continues to be a target for hackers. Regularly updating your core WordPress application enables you to take advantage of all the latest features while also helping to maximize security.

Helpful Tip: Take care to backup your site before every upgrade, to ensure you can roll back in the event you run into problems.

2. Update and audit your plugins

This includes not only updating plugins to the newest version on a regular basis, but also includes replacing out of date plugins with newer, more regularly maintained alternatives. There are tons of free plugins out there, but some still cost you in other ways, including increasing your risk of being hacked or crashing your site. In addition to updating them, make sure your plugins are regularly updated by their developers and that they are not causing conflicts with other plugins. If a plugin is not being updated, then at some point it is very likely to start causing problems.

Another important task is to regularly assess the value of your plugins. Although they add functionality and useful features, they also can weigh your site down and affect your site’s performance. Many simple features can be achieved by adding a very small amount of code to your functions.php file and don’t necessarily require the heavy load of a plugin. Review them regularly and ditch any you can live without.

3. Update or upgrade your WordPress theme

Many free and premium WordPress themes receive automatic updates, but definitely not all. If your theme does not receive automatic updates then you will want to check with the developer to see if they provide manual updates.

Manual updates require FTP access. Make sure you backup your site before updating your theme (unless you are using a child theme, in which case it is always safe to update the parent).  Many theme updates will overwrite any customizations you create to the theme files, including functions.php and the style sheet. The theme developer should lend any support in this area.

If your theme does not have any updates available, or is not regularly updated by the developer, then you may want to look at finding a new theme.

We highly recommend switching to a framework, if you have not already done so. We used to build our own themes from scratch to maximize customization. But the trade off was having to manually update and essentially redevelop the themes when they became outdated. Then we discovered – and fell in love with – WordPress parent/child frameworks. After initially working with the Thesis framework, we started developing child themes for the Genesis framework by Studiopress. Genesis is an excellent framework for many reasons, not least because it updates at the click of a button.

4. Purge unused assets

Unused images and other media files take up space and needlessly increase bandwidth usage. And old, inactive plugins and themes are also a huge security liability (with the sole exception of the default WordPress themes, which are critical for bug testing and should never be deleted).

Inactive plugins should be deleted from your server, including plugins you use on an occasional basis. As a general rule, if a plugin is not actively doing something on your website, delete it. You can easily add it back in to use when you need it. Hackers are familiar with which plugins have security holes, and can easily scan your site to see if any vulnerable plugins are installed (even if they’re “inactive”) and use them to break in.

Outdated themes pose a similar risk to plugins, though not as widespread. Any non-default themes should be removed when not in use. Default themes (the ones that come with WordPress) should not be deleted, but make sure you keep them updated. Depending on which version of WordPress you are running, the default themes for your version should include Twenty Twelve and/or Twenty Thirteen.

5. Fix broken links

Little is more annoying to a site visitor than clicking a link and getting an error page. When linking internally, keep in mind that a link to a post or page may change if you alter the post slug, category, parent, or site URL. If you change anything that could affect a post URL, then you should also update any links on your site that refer to that post or page. Using the “link to existing content” section of the link tool in the WordPress editing window, or the page/post link window on the menu dashboard, can help minimize internal linking issues as links will be updated automatically. But if you manually type or paste in your link URLs into a post, menu or widget then you may encounter linking issues when you move things around.

Further, even if none of your internal links are broken, you may be linking externally. As we learned above, websites occasionally change their permalink structure, and sometimes go offline altogether, rendering certain URLs obsolete.

It’s a good idea to use Google Webmaster Tools or a reliable broken link checking plugin to scan your site for broken links on the regular, and then update or remove them as needed.

Helpful Tip: If you use a plugin to check for broken links, you should ideally deactivate and delete it when not in use (see #4 above).

6. Optimize and clean up your database

Your WordPress database gets junked, like a storage garage, and needs purging every so often.

  • WordPress by default stores every post and page revision, meaning every single time you hit the Publish button, WordPress saves a copy in your database. This makes it easy to roll back to a previous version at any time – especially helpful if you made a mistake – but it also starts to eat up space. You can limit the number of revisions in your config.php file, but it is not retroactive. The only way to delete already-saved revisions is to purge them directly from the database.
  • WordPress also collects comment spam, storing it in your database for a rainy day. And why would it do that? So you can recover a comment incorrectly marked as spam, or so you can review spam comments to identify and block repeat offenders. Unless you are running a script to delete your comment spam, it is probably clogging up your database.
  • When plugins are installed, most will create database entries in your wp-options table.

We recently cleaned out a client’s database, which was full of old post revisions, archived comment spam and options from deleted plugins. This single task cut the database size by more than half, reducing it from more than 50MB to less than 20MB. This not only freed up space on her server, it also sped up her site

7. Backups

Your site should be backed up according to the frequency in which you add new content, enabling you to quickly restore it to a working condition in the event of an attack or bug. If you aren’t regularly adding new content (although if you want to boost your SEO you should be), then you only need a backup when something is changed. If you are blogging or adding new content on the regular (and making the search engines, and your visitors, very happy) then you should update often. If you post daily, then you may want to schedule daily backups. Some hosts offer this for a nominal fee. If you are updating a handful of times each week, then weekly backups are probably fine.  If you update several times per month then make sure you backup once or twice a month.

WordPress essentially consists of three components: the core application, the database, and your content files. As of the time of this posting, the WordPress application is approximately 15MB. If you’re always updating to the latest version (as you should be), there is no need to backup these files. If you are running an older version for compatibility reasons then save a copy of the version you are using and you can then exclude it from your regular backups.
What you will want to back up are your database and your WordPress content files, including plugins, themes, and uploads (images, documents and other media files), which are all concentrated in a directory named wp-content.
