## Why Broken Link Checker?

Every broken link is a strike against your credibility, and your SEO score. But staying on top of them can feel like fighting a never-ending battle. Broken Link Checker gives you an easy way to scan your content and fix issues before anyone notices.

Whether you’re maintaining a personal blog, a client-heavy agency setup, or a content-rich eCommerce site, this plugin saves hours of manual work and helps you keep things tidy.

### Real-Time Link Monitoring
**Scan everything, automatically.**
Broken Link Checker scans your site deeply and frequently, to make sure no broken links are missed. The plugin will scan every inch of your sites, including within posts, pages, custom post types, comments and even embedded media, to ensure your site’s SEO and user experience are not compromised in any way.

### Email Alerts & Dashboard Notifications
**Never get blindsided by a broken link again.**
Choose how and when you want to be notified about broken links. You can receive instant email alerts, get a summary in your WordPress dashboard, and stay in control with flexible scan settings that meet your needs.

### Advanced Search Filtering
**Tailor your search to your workflow.**
Broken Link Checker makes it easy to fine-tune your scan settings, with search and filtering tools that help you check what really matters. Look for specific URLs, or filter by status or error type.

### Two Link Checking Engines
**Choose the right option for your site.**
Broken Link Checker gives you the option of using two unique engines based on your needs. Scan your content locally, or opt for the cloud-based checker for better performance and reduced server load.

### Fix Links Without Leaving the Page
**Manage broken links efficiently.**
No need to dig through old posts. Broken Link Checker lets you resolve all detected links right from your BLC dashboard. Bulk action means you can clean up dozens of links from the plugin interface with just a few clicks.

### Multisite & Agency Ready
**One plugin to manage them all.**
Handle broken links across multiple sites – not just one! Perfect for if you’re running a multisite network or managing multiple client installs.

## Broken Link Checker: Choose The Right Link Checking Engine for Your Needs

With Broken Link Checker, you’ll have the flexibility to choose between a fast, cloud-based engine or a reliable, local solution. You can scan your site either way, and even switch between them without losing your saved settings.

  

Not sure which one is right for you? Here’s a quick breakdown to help you decide:

### Cloud-Based Engine:

 == Frequently Asked Questions ==
=Is Broken Link Checker really free?=  
Yes! The plugin is completely free and includes all the core scanning features. The plugin works either locally on your own server, or 20x faster, better and more accurately on WPMU DEV cloud servers. The Local version only works in your site admin, while the Cloud version works in both your site admin and in your Hub.

The cloud version requires a connection to WPMU DEV to access its API. However, you don’t need to be a premium WPMU DEV member to access the cloud version! You can create a free Hub account (with some restrictions) directly in the plugin while settings things up.

=Does it work with custom post types and fields?=  
Absolutely. You can scan everything from custom fields to WooCommerce product links.

=Can I use it on Multisite?=  
Yes, Broken Link Checker supports WordPress Multisite and gives you full flexibility.

=Will it mess up my theme or content?=  
Nope. The plugin doesn’t modify your content. It just finds the broken links and gives you options to manage them.

= How can I report security issues or bugs? =
We take plugin security incredibly seriously; if you have a bug or vulnerability to report, you can do so through the Patchstack Vulnerability Disclosure Program. It’s fast, easy, and you will be notified when the issue is fixed. [Report a vulnerability](https://patchstack.com/database/wordpress/plugin/broken-link-checker/vdp).

= 0.5.12 =
* Let the user set a custom temporary directory, if the default one is not accessible for some reason.

* Fix a bug when the plugin creates a DB table with the wrong prefix.

= 0.5 =
* This is a near-complete rewrite with a lot of new features.

= 0.4.10 =

* "Unlink" and "Edit" now work for images, too. "Unlink" simply removes the image.
