I just audited a WordPress site with 67 active plugins. The site does what a small theme and 6 plugins could do.
That is not a typo and it is not even the worst one I saw this year. The owner was lovely about it. They had inherited the site, every plugin had been installed by someone with a real reason at the time, and nobody had ever sat down and asked which ones were still earning their keep. So the list just kept growing, one well-meaning install at a time, until the admin dashboard took eleven seconds to paint and the front end was creaking under the weight of a dozen scripts nobody had asked for.
I want to walk through the categories that come up again and again, because if you run a WordPress site in 2026 there is a real chance you are running at least two of these right now. None of this is a dunk on the plugin authors. Most of these tools were genuinely useful five or ten years ago. The hosting landscape has moved on, and a lot of the work has quietly migrated to the server, the CDN, or core itself.
1. Five different SEO plugins running at once
I keep finding sites with Yoast, Rank Math, All in One SEO, a schema plugin, and SEOPress all active at the same time. Each one writes its own meta tags. Each one tries to inject its own schema. The page source ends up with three competing canonical URLs and two sets of Open Graph tags, and Google quietly picks whichever one it feels like.
Pick one. Delete the other four. The one you keep should be the one whose interface you actually enjoy opening, because the on-page SEO features are roughly equivalent in 2026. The difference is in the workflow, not the output.
2. Image optimization plugins on hosts that already optimize at the CDN
If your host is Kinsta, WP Engine, Cloudways with Cloudflare Enterprise, Rocket.net, or anything that fronts your media with a modern image CDN, the CDN is already converting to WebP or AVIF on the fly, resizing on the fly, and serving the right format per browser. Running Smush or ShortPixel on top of that means you are doing the same job twice, paying for a plugin license, and adding a queue that slows down every upload.
Check what your host actually does at the edge before you install anything. Nine times out of ten, the answer is everything you need, and you can deactivate the plugin and watch your media library page load faster the same afternoon.
3. Cache plugins on hosts with object cache enabled at the server level
WP Rocket and W3 Total Cache were essential when shared hosting meant a single Apache process and no Redis. Today most managed hosts run Redis or Memcached as part of the stack, page caching happens at Varnish or at the CDN, and the cache plugin you installed is mostly fighting with the server for control of the same headers.
Ask your host what is cached and where. If the answer includes object cache, page cache, and a CDN, you almost certainly do not need a plugin doing the same thing from inside PHP. Keep one only if you genuinely use its asset-optimization features and nothing else does that job.
4. Security plugins that mostly add a settings page and a banner
A real security posture is a firewall in front of the site, two-factor on the admin login, a host that patches the stack, and a habit of keeping plugins updated. A lot of the popular security plugins do add value, but a surprising number of installs I see are running the free tier of one, which in practice means a dashboard widget showing a green checkmark and not much else.
If the plugin is not actively scanning, not blocking anything at the firewall layer, and not enforcing 2FA, it is decoration. Replace it with a real WAF at the edge (Cloudflare, Sucuri, or your host's own) and the 2FA plugin you trust, then delete the rest.
5. Form plugins added just in case and never used
This one is so common it is almost funny. The site has Contact Form 7, WPForms, Gravity Forms, and Ninja Forms all active. Two of them have no forms at all. One has a single contact form from 2019. The other is the one actually rendering on the contact page.
Pick the one you actually use. Export the live form if you need to. Deactivate the other three, wait a week to confirm nothing broke, then delete them. Every form plugin loads its own JavaScript on every page by default, so this category alone is often worth 200 to 400 KB of front-end weight.
6. Backup plugins on hosts that already snapshot daily
If your host takes a daily snapshot and keeps two weeks of restore points (almost every managed WordPress host does this in 2026), running UpdraftPlus on top is duplicate work. You are paying CPU and storage to back up to Dropbox what the host already backs up to its own cold storage, and the host's restore button is faster and more reliable than the plugin's.
The exception is if you specifically want offsite backups under your own control, which is a fair reason to keep one. Most owners do not, they just installed it because a tutorial said to.
The cure is one audit every six months
None of this needs to be a project. Put a recurring calendar event every six months, open the plugins page, and walk down the list. For each plugin ask one question. Is this earning its keep right now, today, on this site?
Deactivate the ones that are not. Do not delete yet. Monitor for a week. If nothing breaks and nobody complains, delete. If something breaks, you learned something useful about what that plugin was actually doing, and you can put it back with confidence.
That is the whole routine. Twenty minutes twice a year. The compounding effect is enormous, because every plugin you do not have is a plugin you do not have to update, audit for vulnerabilities, troubleshoot when it conflicts with the next one, or load on every request.
A clean WP install is a fast WP install. Most WordPress is slow complaints are I installed 40 things complaints. 🌱
