Navi.

In this step-by-step guide, we‘ll walk you through everything you need to know to master post revisions and simplify your content workflow.

What Exactly Are WordPress Post Revisions?

WordPress post revisions is a built-in feature that automatically saves a copy of your post or page each time you make changes. Think of it like version control for your content. With revisions, you can:

Revert to an earlier version if you make a mistake
Compare changes between different versions
See who made specific changes and when

Pretty handy, right? Post revisions have been a core feature since WordPress 2.6, so you can take advantage of them no matter what version you‘re using.

How WordPress Handles Revisions Behind the Scenes

When you save a post or page, WordPress stores a new revision in your database, including:

The updated content
The author who made the changes
A timestamp of when the changes were made

WordPress is smart about how it stores revisions to avoid bloating your database. Instead of saving the entire post for each revision, it only saves the differences (called a "diff") between each version. This keeps revision storage compact.

By default, WordPress saves an unlimited number of revisions for each post. But don‘t worry – all those revisions won‘t slow down your site. WordPress only loads them when you‘re viewing the revisions screen in the editor.

Revisions by the Numbers: WordPress Statistics

To give you an idea of how widespread post revisions are, check out these stats:

Over 43% of all websites use WordPress, and all of them have revisions enabled by default
An average WordPress post has 3-5 revisions saved
For a site with 100 posts, that‘s 300-500 revisions stored in the database
Revisions can account for up to 15% of a WordPress site‘s database size

While those numbers might sound alarming, remember that revisions are a necessary tradeoff for the ability to safeguard your content. We‘ll share some tips later for keeping your revisions under control.

How to Access and Use Post Revisions

Ready to put revisions to work? Here‘s how to access and use them in the WordPress editor:

Edit a post or page, then click the "Revisions" link in the publish panel on the right.
You‘ll see a slider at the top of the revisions screen. Drag the slider to compare different revisions side-by-side. Changes are highlighted in red and green.
Click the "Restore This Revision" button to revert to an earlier version.

It‘s that easy! Revisions work the same whether you‘re using the new block editor or the classic editor.

Here are a few more tips to get the most out of revisions:

Use the "Compare any two revisions" checkbox to freely compare different versions
The author and timestamp for each revision is shown in the header
Revisions also work for custom post types if your theme supports it

Putting Revisions to Work: Real-World Examples

To illustrate the power of post revisions, let‘s walk through a few real-world scenarios:

Scenario 1: Undoing Accidental Changes

Imagine you‘re editing a lengthy blog post and accidentally delete several paragraphs. Panic time? Not with revisions! Just open the revisions screen, locate the version before your accidental edit, and restore it. Crisis averted.

Scenario 2: Collaborating with Multiple Authors

You‘re working on a post with several contributors, each making their own changes. With revisions, you can see exactly who changed what and when. If one author goes rogue and makes edits you don‘t approve of, simply revert back to an earlier version.

Scenario 3: Tracking Changes Over Time

Let‘s say you‘re writing a post that you continually update over several weeks. Revisions allow you to see how the post has evolved and track your progress. You can also compare older and newer versions to see what‘s changed.

Best Practices for Managing Revisions

While revisions are incredibly useful, they can get out of hand if not managed properly. Here are some best practices to keep in mind:

Limit your revisions: If you don‘t need an unlimited revision history, you can limit the number of revisions WordPress saves. Add this line to your wp-config.php file:
```
define( ‘WP_POST_REVISIONS‘, 10 );
```
Replace 10 with the number of revisions you‘d like to store.
Delete old revisions: Over time, revisions can pile up and bloat your database. Use a plugin like WP-Optimize to clean up old revisions and keep your database lean.
Disable revisions on simple pages: For pages with minimal content changes, you might not need revisions at all. Use a plugin like Disable Post Revision to turn off revisions on specific post types.

Frequently Asked Questions

Before we wrap up, let‘s address some common questions about WordPress revisions:

What‘s the difference between a revision and an autosave?

WordPress saves two types of revisions: manual and automatic. Manual revisions are created when you click "Save Draft", "Publish", or "Update". Automatic revisions (called autosaves) are saved every 60 seconds while you‘re editing. Autosaves are temporary and are replaced with each new autosave.

Can I disable revisions completely?

Yes, you can disable revisions by adding this line to your wp-config.php file:

define( ‘WP_POST_REVISIONS‘, false );

Keep in mind that disabling revisions means you won‘t be able to revert to an earlier version if needed.

Do revisions affect site performance?

Revisions have minimal impact on front-end performance since they‘re only loaded in the editor. However, having an excessive number of revisions can slow down your wp-admin and bloat your database. That‘s why it‘s important to manage your revisions.

Can I use revisions with custom fields or page builders?

By default, revisions only track changes to the main post content and title. However, some plugins like Advanced Custom Fields add support for tracking custom field revisions. Many page builder plugins also include their own revision systems.

Conclusion

WordPress post revisions are a powerful tool for safeguarding your content and collaborating with others. By understanding how revisions work and following best practices, you can use them to streamline your workflow and never worry about losing changes again.

To recap, here are the key points we covered:

WordPress automatically saves a revision each time you make changes to a post or page
You can access revisions in the editor to compare changes and restore earlier versions
Revisions are stored efficiently in the database and don‘t impact front-end performance
It‘s important to manage revisions to avoid database bloat and wp-admin slowdowns
