At WPBeginner, we understand that being transparent about the age of your posts boosts credibility and trust. That’s why we regularly update our older content and clearly display the date of the last update on each post. You may like to take that further with an old post notification.
Over the years, we’ve noticed something interesting about successful websites: they’re honest about when their content was published. Users appreciate knowing if they’re reading something from last month or three years ago. It helps them understand whether the information is relevant.
We’ll walk you through the simple process of adding old post notifications to your WordPress site. This small addition can make a big difference in how users perceive your content and can even help with SEO by showing search engines you care about content freshness.
Why Add Old Post Notification to WordPress Blog Posts
Here’s a reality check: some of your best content might be hurting your website’s credibility. When visitors land on a three-year-old tutorial about a software that’s been updated five times since then, they’re not getting the help they need.
Outdated content can lead to frustrated users, higher bounce rates, and lower search rankings. Google prioritizes fresh, accurate content, and outdated information sends the wrong signals.
The ideal solution? Update every old post with current information.
But let’s be realistic. If you’ve been blogging for years, you probably have hundreds of posts. You may not be able to update them all due to limited time and resources.
That’s where old post notifications become a smart compromise. They give your readers a heads-up that they’re viewing older content, so they can make informed decisions about how to use that information. It’s about transparency and trust.
Many successful websites also display the ‘last updated’ date instead of just the publish date. This approach works especially well for evergreen content that you regularly refresh.
Now let’s dive into the practical steps. We’ll show you how to add old post notifications to your WordPress site and how to display last updated dates that build credibility with both users and search engines.
Method 1. Display Old Post Notification Using Plugin
This method is easier and recommended for all users who want to display an old post notification.
First, you need to install and activate the DX Out of Date plugin. For more details, see our step-by-step guide on how to install a WordPress plugin.
Note: The DX Out of Date plugin has not been updated for some time. But in our testing, it is still working fine both with classic and block themes.
Upon activation, you need to visit the Settings » Out of Date page to configure plugin settings.
Here, you need to choose the period and duration. This is the time after which a post will be considered old by the plugin.
Below that you can provide a custom message to display on older posts and enable the notification to be displayed for all old posts. Don’t worry, you’ll be able to hide it for specific posts by editing them.
On the settings page, you can also choose post types, colors for the notification box, and add custom CSS if needed.
Don’t forget to click on the Save Changes button to store your settings.
You can now visit an old post on your website to see the plugin in action.
Hiding Old Post Notification on Individual Posts
Now let’s say you have an older article that is still accurate, up-to-date, and has great search rankings. You may want to hide the old post notification there.
Similarly, what if you have updated an old post with new information? The plugin will keep showing old post notifications because it uses the post’s published date to determine its age.
To fix this, you can edit the post and scroll down to the ‘Out of Date Notification’ tab under the Post panel of the block editor. From here, simply uncheck the notification option and save your changes.
The plugin will now stop showing old post notifications on this particular article.
Method 2. Display Last Modified Date for Your Posts
A lot of WordPress websites display the last modified date for their blog posts. Some replace the publish date with the last modified date as well.
The advantage of this method is that it shows users when a post was last updated without showing an old post message.
First, you need to install and activate the WP Last Modified Info plugin. For more details, see our step-by-step guide on how to install a WordPress plugin.
Upon activation, head over to Settings » WP Last Modified Info page to configure plugin settings.
On the settings page, you need to turn on the Global display of the last modified info toggle. After that, you can choose how you want to display the modified date.
You can replace the published date, show it before or after the content, or manually insert it into a post.
Below that, you’ll find a bunch of options. If you are unsure, then you can leave them to default.
Don’t forget to click on the Save Settings button to store your changes.
You can now visit your website to see the last updated information for all your blog posts.
The problem with this method is that it will show the last updated date for all posts including the newer posts.
You can set a time gap under plugin settings. But this gap is only limited to 30 days.
The plugin also provides three blocks that you can manually insert into a post or page to display the last modified info.
You also have the option to use custom CSS to style your last updated date notice. We used the following custom CSS in the screenshots above.
p.post-modified-info {
background: #fbffd8;
padding: 10px;
border: 1px solid orange;
font-size: small;
font-weight: bold;
}
Method 3. Add Old Post Notification Using Code
This method requires you to manually add code to your WordPress theme files. If you haven’t done this before, then take a look at our guide on how to add custom code snippets in WordPress.
Simply copy and paste the following code in your theme’s single.php template.
// Define old post duration to one year
$time_defined_as_old = 60*60*24*365;
// Check to see if a post is older than a year
if((date('U')-get_the_time('U')) > $time_defined_as_old) {
$lastmodified = get_the_modified_time('U');
$posted = get_the_time('U');
//check if the post was updated after being published
if ($lastmodified > $posted) {
// Display last updated notice
echo '<p class="old-article-notice">This article was last updated ' . human_time_diff($lastmodified,current_time('U')) . ' ago</p>';
} else {
// Display last published notice
echo '<p class="old-article-notice">This article was published ' . human_time_diff($posted,current_time( 'U' )). 'ago</p>';
}
}
This code defines old posts to be any articles published at least one year ago.
After that, it checks if a post is older than a year. If it is, then it checks if the post was updated after publication. Then it displays a notice based on those checks.
Here is how it looked on our demo website for post that is old and was never updated.
Here is how it looked for a post that is old, but was updated after being published.
We customized the old post notification with the following custom CSS.
p.old-article-notice {
background: #fbffd8;
padding: 10px;
border: 1px solid orange;
font-size: small;
font-weight: bold;
}

As a reader of a blogs, I prefer blogs that do have dates and specifically telling me last time they reviewed the blog for accuracy. Not just when they made an update. Often I am looking for solutions to answers and this type of info goes a long way towards accuracy of information.
As a blogger, I always included dates. And since a few of my blogs do occasionally need update, I always add when the post was last looked at and what changes if any where made.
Again this all does go back to the type of content in blog. Some content stands the test of time, but blogs with instructions and guides are just important, imho.
