Most small business WordPress sites run between 15 and 30 plugins. Some of those plugins are essential. Some are redundant. And some are actively putting your site at risk — either through security vulnerabilities, performance drag, or the simple fact that nobody is maintaining them anymore.
This checklist gives you a practical framework for evaluating every plugin on your site. You do not need to be a developer to use it. You need about 30 minutes and access to your WordPress dashboard.
The Checklist
For each plugin on your site, run through these questions. Any plugin that fails multiple checks deserves serious evaluation — and possibly replacement.
1. Has It Been Updated in the Past 6 Months?
Check the "Last updated" date on the plugin's wordpress.org page. A plugin that has not been updated in over 6 months is falling behind WordPress core updates and accumulating compatibility risk. After 12 months without an update, WordPress itself flags the plugin with a warning. Do not wait for the warning.
Where to check: Go to Plugins in your WordPress dashboard, click "View details" on the plugin, or search for it on wordpress.org.

2. Is It Tested With Your WordPress Version?
The "Tested up to" field tells you the highest WordPress version the developer has verified compatibility with. If your site runs WordPress 6.7 and the plugin says "Tested up to: 6.2," that is a five-release gap. The plugin might work, but it has not been verified — and if something breaks, you are on your own.
3. Does the Developer Respond to Support Requests?
Open the plugin's support forum on wordpress.org. Look at the past 2-3 months of threads. Are there unanswered questions? Unresolved bug reports? Has the developer responded to anything recently? A support forum full of unanswered posts is a strong signal that the plugin is no longer being actively maintained.
4. Does the Plugin Have Known Vulnerabilities?
Check vulnerability databases like WPScan, Patchstack, and Wordfence's threat intelligence feed. Search for your plugin name. If a vulnerability has been reported and no patch has been released within a reasonable timeframe (typically 30-90 days), the plugin is a security liability that should be replaced immediately.
Security plugins like Wordfence and Sucuri can also scan your installed plugins against known vulnerability databases automatically.
5. Is the Plugin Actually Being Used?
This is the most overlooked question. Many WordPress sites have plugins installed that were needed once and never removed — a plugin from a past promotion, a testing tool left active, a feature that was replaced by something else. Every active plugin adds code that runs on every page load, increases your attack surface, and adds maintenance burden.
Go through your plugin list and honestly assess whether each one provides functionality your site currently needs. If you cannot explain what a plugin does without looking it up, investigate before assuming it is necessary.
6. Are You Running Redundant Plugins?
It is common to find WordPress sites running two caching plugins, two SEO plugins, or three security plugins — each installed at a different point by a different person. Redundant plugins do not just waste resources; they actively conflict with each other and can cause performance problems, database bloat, and unpredictable behavior.
For each category of functionality (SEO, caching, security, forms, analytics), you should have exactly one plugin. If you have more, decide which one to keep and properly remove the others.
Found some red flags?
Do not just start deleting things. Let us handle the replacements safely so nothing breaks and no data is lost.
7. How Many Active Installations Does It Have?
A plugin with 500,000+ active installations has a large community testing it, reporting bugs, and pressuring the developer to fix issues. A plugin with 200 active installations is essentially untested in the wild. Low installation counts are not disqualifying — small niche plugins can be excellent — but they do increase risk.
Combine this with the support forum activity check. A low-installation plugin with an active developer responding to every issue is far safer than a moderate-installation plugin with a silent developer.
8. Does the Plugin Affect Site Speed?
Some plugins add significant overhead to every page load — loading JavaScript and CSS files, making external API calls, or running complex database queries. Use your browser's developer tools (Network tab) to see what resources each plugin loads on the front end. Use a plugin like Query Monitor to see database queries being run on each page.
If a plugin adds 500ms or more to your page load time, evaluate whether its functionality justifies that cost. Often, a lighter alternative exists that provides the same feature with less performance impact.
9. Is the Plugin From a Trustworthy Source?
Plugins from the official wordpress.org repository go through a basic review process. Plugins downloaded from random websites, nulled (pirated) premium plugins, or plugins shared via email have no such review and can contain malicious code. If you have any plugins that were not installed from wordpress.org or a legitimate premium vendor, investigate their origin immediately.
10. Does Your Site Have Too Many Plugins?
There is no magic number, but there is a practical principle: every plugin you add increases complexity, maintenance burden, and potential for conflicts. A site with 15 well-chosen, actively maintained plugins is healthier than a site with 8 plugins where half are abandoned. Focus on quality and necessity, not count.
That said, if your site has more than 30 active plugins, it is worth a critical review. Some of that functionality can likely be consolidated, removed, or handled by your theme.
What to Do With Your Results
After running through this checklist, sort your plugins into three categories:
- Keep — Actively maintained, necessary, performing well
- Replace — Needed functionality, but the current plugin is outdated, abandoned, or risky
- Remove — Not needed, redundant, or too risky to keep
For plugins in the "Replace" category, see How to Replace an Old WordPress Plugin Without Breaking Your Site. For plugins in the "Remove" category, see Should You Delete an Abandoned WordPress Plugin? for the safe removal process.
If you would rather have someone do this for you, our WordPress Plugin Fix and Replacement Service includes a full plugin audit with a prioritized action plan. We check every plugin on your site, score it against these criteria, and handle the replacements and removals safely.

Frequently Asked Questions
Q: How often should I run this checklist?
Every 3 months is a good cadence for most small business sites. Plugin maintenance status can change quickly — a developer can stop responding to support requests between one quarter and the next. Setting a quarterly reminder ensures you catch problems before they become emergencies.
Q: Can I automate any of these checks?
Partially. Security plugins like Wordfence and Sucuri automatically flag known vulnerabilities. Some managed hosting providers monitor plugin update status. But the qualitative checks — support forum activity, actual usage, redundancy — require a human review. Automation handles the easy signals; judgment handles the rest.
Q: What if a plugin fails the checklist but my site seems fine?
A plugin can be a risk without causing visible problems today. Security vulnerabilities exist whether or not they have been exploited yet. Performance drag accumulates gradually. Compatibility breaks happen suddenly when the next WordPress update ships. The checklist identifies risk, not current damage. Addressing risks proactively is always cheaper than responding to emergencies.
Q: How many plugins is too many?
There is no universal number. A site with 25 well-maintained, necessary plugins is healthier than a site with 10 where half are abandoned. Focus on whether each plugin is maintained, necessary, and performing well. If you cannot justify a plugin's presence on your site, it should not be there.
Q: Should I remove plugins I paid for?
The fact that you paid for a plugin does not mean it should stay on your site. If a premium plugin is no longer maintained, has known vulnerabilities, or is no longer necessary, it should be replaced or removed like any other plugin. The sunk cost of the purchase should not factor into your security decisions.
Q: Is it better to have fewer plugins or to use a multipurpose plugin?
Multipurpose plugins (like Jetpack or all-in-one security suites) can reduce your total plugin count, but they come with their own trade-offs — larger codebases, more potential attack surface, and features you may not need running in the background. The best approach is to use the minimum number of focused, well-maintained plugins that cover your actual needs.
Q: What should I do if my entire site is running on outdated plugins?
Do not try to update everything at once. Prioritize by risk: replace plugins with known security vulnerabilities first, then address abandoned plugins that handle critical functionality, then work through the rest. A professional plugin audit can give you a prioritized action plan so you address the highest-risk items first.
