Do I need a plugin for this?

No. Every extra plugin is more maintenance and another security surface. A check from outside needs none of that.

What about posts from five years ago?

They can stay. What matters is that they don't read as current news and don't contain details that are no longer accurate.

Can widgets really hide outdated content that long?

Yes — because they don't show up in the normal page list, a widget written once during setup can go years without a second look.

How do I stop the footer year from going stale?

Render it from the site's current date instead of typing a fixed year, so it updates itself every January.

Finding outdated content in WordPress

In WordPress, outdated text usually sits outside the pages you normally edit: sidebar and footer widgets, reusable blocks, theme settings such as promo banners, and old posts still reachable through archives. The fastest way to find them is to read the published site from the outside, without adding a plugin.

Have your WordPress site checked from outside

Enter your address and see the result right away. No plugin, no access, no risk.

No account, no credit card. Takes a minute.

So geht es

1Check widgets. Open Appearance → Widgets and read every text block — promotions live here longest.
2Review blocks. Open reusable blocks; one change here affects every page that uses it.
3Filter old pages. Sort the page list by date and look at anything older than two years.
4Check from outside. Look at the published address with DustOff — it finds what the admin area hides.

Where WordPress hides old text

These areas sit outside the pages you'd normally open while editing, which is exactly why they stay untouched the longest:

Widgets in the sidebar and footer
Old posts that still surface through archive pages
Reusable blocks placed on several pages at once
Theme settings holding text such as promo banners
Pages with no menu entry, still reachable only through search

Why it's easy to miss

WordPress separates content from presentation on purpose, which is great for design and bad for spotting old text: a sentence can live inside a widget, a block, or a theme setting and still show up on every single page without ever appearing in your normal editing view.

Outside in, not inside out

The admin area shows you pages, not sentences. DustOff takes the opposite route: it reads the published site the way a visitor sees it, and reports the sentences that no longer hold true today — regardless of which WordPress field they happen to live in.

Nothing gets installed, there's no access to your system, and no plugin that would need updating alongside everything else.

Two quick habits in the editor

Sort Pages by last-modified date. Whatever sits at the bottom hasn't been touched in the longest time — it's the fastest shortlist WordPress gives you for free.

Check which posts are pinned to the top. A post from 2023 pinned above everything else is the single most common reason a site reads as stale, even when new content is being published regularly underneath it.
