How Many WordPress Plugins Is Too Many?
By the LA Web Design team5 min read
Ask around and you'll hear rules like “never more than 20 plugins.” The number itself isn't the problem. A website running 30 small, well-maintained plugins can be faster and safer than one running eight badly built ones. What matters is what each plugin does, how well it's built, and whether anyone is still maintaining it.
Each plugin is code you're trusting
Every plugin adds code that runs on your website, written by a developer you've probably never looked into. The large majority of WordPress security holes are found in plugins, not WordPress itself. Some plugins also load their scripts and styles on every page, even pages that don't use them, which is one of the most common reasons a WordPress website feels slow.
Go through the list
Open the Plugins screen and take them one at a time. For each, ask whether you still use it and when it was last updated. A plugin that hasn't been updated in more than a year, or one that's been closed in the WordPress plugin directory, is a risk worth replacing. Look for two plugins doing the same job, too. It's common to find two SEO plugins, two caching plugins, or a forms plugin left over from a previous redesign.
Delete deactivated plugins rather than leaving them in place. Deactivated code still sits on the server, and some vulnerabilities can be reached without the plugin being switched on.
Watch out for add-on packs
A common source of bloat is the add-on pack: a bundle of dozens of extra widgets for a page builder, installed to use two of them. Those packs often load their files everywhere. If you only need a couple of features, there's usually a lighter way to get them.
What most business websites actually need
A typical business website runs well on a short list: an SEO plugin, a forms plugin, backups, security (or a host that handles it), and caching if the host doesn't provide it. Online stores, booking systems, and memberships add more. Beyond that, every addition should earn its place.
Back up before you remove anything big
Take a backup before removing plugins, and work on a staging copy if your website has one. Some plugins leave shortcodes or settings behind that break a page once they're gone. If you can't tell what a plugin does, that alone is a sign it should be reviewed by whoever manages the website.
We keep plugin lists short on every WordPress website we build, and plugin review is part of ongoing maintenance. If speed is your main worry, our piece on why websites feel slow covers the rest.
