How to Fix: Plugins up to date

Plugins up to date is an important SEO check in the WordPress Specific category. This is a high-priority SEO issue that should be addressed soon. It has a significant impact on your SEO performance.

What this check is really about

This check flags plugins running behind their current release. It reads like a housekeeping nag and it is anything but. An out-of-date plugin is the single most common way a WordPress site gets compromised, and a compromised site is an SEO catastrophe — Google will deindex a site serving malware or spam faster than any ranking factor could ever help you. This is not a polish item. It is the lock on your front door.

There is a second, quieter risk the check is pointing at, and it is the one I care about more after thirty years in this trade: the plugin that is not just out of date but abandoned. An update you have not applied is a chore. A plugin whose author has walked away is a liability with a fuse on it.

Why it matters for SEO

• Known vulnerabilities in old plugin versions are the top vector for site compromise, and a hacked site gets deindexed
• Outdated code breaks against new WordPress and PHP releases, causing errors that hurt crawlability and Core Web Vitals
• Security patches are frequently the whole point of a release; skipping them leaves a published, documented hole open
• Bloated, unmaintained plugins drag page speed, which is a direct ranking input

How to check whether you have this problem

Plugins → Installed Plugins shows update badges at a glance, but that only tells you what is behind, not what is dead. For each plugin also check the “last updated” date and the “tested up to” WordPress version on its repository page. Anything not touched in a year, or not tested against a current WordPress release, gets a hard look regardless of whether an update is pending. The SEO Roadmap audit surfaces the out-of-date list; your judgement handles the abandoned ones.

A tech I watched die on schedule

Let me tell you why abandoned software makes the hair on my neck stand up. I spent a chunk of my career building in Flash and ActionScript — multi-user games, interactive CD-ROMs, whole campaigns that ran on the Flash Player. For a decade it was everywhere, and it felt permanent. It was not. The platform was declared end-of-life, browsers pulled support on a published timetable, and on the cutoff date a great deal of working software simply stopped running. Not degraded. Stopped. The clients who had treated Flash as furniture — install once, never think about it — got the worst of it, because they had built load-bearing things on a dependency that had quietly stopped being maintained years before it was formally switched off.

An unmaintained WordPress plugin is a small Flash. It works right up until the release of WordPress or PHP that it was never updated to survive, and then it fails — sometimes loudly, sometimes silently by leaving a security hole open. The lesson I carry from watching Flash go out on schedule is simple: dependencies are not furniture. Every one of them is a live commitment by someone else to keep it alive, and the day that commitment ends is the day it becomes your problem. Update relentlessly, and treat “last updated: two years ago” as the warning it is.

How to fix this in WordPress

Difficulty Level: EASY – This fix is straightforward and can typically be completed by anyone with basic WordPress knowledge.

Estimated Time: 15 min

Step 1: Back up first, always

Take a full backup — files and database — before you touch anything. Fifteen minutes of updates is cheap; an unrecoverable site is not. If you have staging, run the updates there first.

Step 2: Update in small batches, not all at once

Update a few plugins, then load the front end and the admin and confirm nothing broke, then do the next few. Bulk-updating everything in one click is how you end up with a white screen and no idea which plugin caused it. On a store, update WooCommerce and its extensions together and away from a payment-processing peak.

Step 3: Retire the abandoned ones

For any plugin that is abandoned, find a maintained replacement or remove it. Deactivating is not enough — an inactive plugin’s files still sit on disk and can still be exploited. Delete what you are not using. A smaller plugin footprint is faster, safer, and easier to reason about.

Step 4: Verify and keep it that way

1. Clear your caching plugin and walk the key pages, checking for layout or function breakage
2. Enable auto-updates for the plugins you trust to reduce future drift
3. Re-run the SEO Roadmap audit to confirm the check passes
4. Check Google Search Console after a few days for any new crawl errors

What I would not do

• Do not bulk-update everything at once with no backup and no staging pass
• Do not leave deactivated-but-installed plugins on disk; delete what you do not use
• Do not keep an abandoned plugin running because “it still works” — that is exactly the trap
• Do not update on a Friday afternoon; give yourself a working day to catch fallout
