Broken Link Checker by AIOSEO – Find & Fix Broken Internal, External & Video Links

Broken links hurt your SEO and send visitors to dead 404 pages. Broken Link Checker by AIOSEO scans your whole WordPress site for broken links and shows you exactly which ones to fix. It checks internal links, external links, broken images, and video links, then lets you fix or remove them in a few clicks without editing each post by hand. This free plugin connects to your AIOSEO account and scans up to 250 internal links every month at no cost, with credits that renew each month. Upgrade to a paid subscription to scan more internal and external links, monitor more frequently, and cover larger sites. See Broken Link Checker pricing and upgrade here. 🔗 Find Broken Internal and External Links Broken Link Checker monitors every internal link and external link on your WordPress website and reports which links work and which are broken. It crawls your content on a schedule and records the status of each link: a working 200 response, a 301 or 302 redirect, or a broken 404. You get a clear list of broken links to fix, so dead links never sit on your pages unnoticed. 🎥 Check Broken Video Links on YouTube, Vimeo, and More Video links break in a way that a normal link check misses. A YouTube or Vimeo page can still load and return a working status long after the video was deleted, set to private, or removed by the uploader. Broken Link Checker auto-detects video links and verifies that the video behind each link still exists. It checks the video itself across YouTube, Vimeo, and more than ten other platforms, then flags the ones that are gone so you can swap in a working video. It covers both the videos you link to and the ones you embed, including the players a page builder or a pasted embed code writes as an iframe, so a video that was taken down does not leave a dead player sitting on your page. This keeps tutorials, reviews, and any post built around an embedded or linked video from quietly going stale. 🖼️ Detect Broken Images Broken Link Checker also finds broken images. If an image file was moved, renamed, or deleted, the plugin reports the broken image URL next to your broken links so you can replace it before visitors land on a missing graphic. It covers the images in your content, the ones a block keeps in its own settings, and the ones a block or a page builder section uses as a background. It also reports audio files that no longer load. 🔒 Catch the Links That Look Fine But Are Not A link check that only reads the status code misses the links that answer perfectly and still fail your visitors. Broken Link Checker reports a destination whose SSL certificate has expired or does not match the site, because a browser stops your visitor with a full-page warning no matter what the server answered. It also tells you why every other broken link failed, instead of only that it did: blocked, timed out, unreachable, an address that cannot exist, or a page that is there and asks to be signed in to. That last one matters, because a link behind a login is not broken at all - and a report that calls it broken sends you looking for a fault in an address that is fine. The reason appears in the report, on the frontend highlighter, and in the CSV export. 🧭 Find Links Everywhere, Not Just in Post Content Plenty of links never appear in the body of a post, and a checker that only reads post content misses every one of them. Broken Link Checker looks in all the other places a link hides on a WordPress site:

• Custom fields - including Advanced Custom Fields (ACF) link, URL, and text fields.
• Navigation menus - custom links in your menus, which often point at pages that were later renamed or deleted.
• Category and tag descriptions - links in your term descriptions.
• Author bios and websites - links on user profiles.
• Post excerpts - links in the excerpt as well as the content.
• Synced patterns, templates, and template parts - block content the editor stores outside your posts, including navigation blocks.
• Embeds - links behind embed blocks that are not videos.

Every broken link is reported with the exact place it was found, so you know whether to open the post editor, the menu editor, or a user profile to fix it. Each source can be switched on or off in the settings. 🧱 Supported Page Builders If your pages are built with a page builder, your links live in builder data rather than plain post content. Broken Link Checker reads those layouts directly, so a builder page is checked like any other content. The report tells you which link is broken and which page holds it, then sends you to that builder to change it - rewriting a layout in place is the builder's job, not ours:

• Elementor
• Divi - both Divi 4 and Divi 5 layouts.
• WPBakery Page Builder
• SiteOrigin Page Builder
• Avada Builder (Fusion Builder)
• SeedProd
• The WordPress block editor - including reusable and synced patterns.

☁️ Cloud-Based Scanning That Does Not Slow Down Your Site Broken Link Checker by AIOSEO runs as a cloud service connected to your AIOSEO account, so the link scanning happens on our servers instead of yours. Other broken link checker plugins crawl from your own server, which can spike resource usage, get your hosting account flagged, or cause your server IP to be blocked. With cloud-based link scanning, your site speed stays the same and your hosting provider has no reason to throttle you, even on large sites with thousands of links. 🎯 Granular Control Over What Gets Scanned You decide what Broken Link Checker monitors. Choose which post types to scan, such as pages, posts, and custom post types, and which post statuses to include, such as published, draft, or pending review. This keeps the scan focused on the content that matters and your link credits spent where they count. 🚫 Exclude URLs You Do Not Want Checked Some links should not be checked at all. Affiliate links, tracking redirects, and third-party URLs that block automated requests can show up as false broken links. Broken Link Checker lets you exclude URLs by exact address, by wildcard, by host, or by regular expression - all in a single exclusion list - so your broken link report stays accurate. Remove an exclusion later and the links it was hiding come back. 📊 See What to Fix First A long list of broken links does not tell you where to start. The dashboard ranks the fixes that clear the most broken links for the least work: one dead address used in dozens of places, a domain that has gone offline, a page carrying several at once. It also shows why your links fail and how long each has been broken, and every figure opens the report already narrowed to it. 🛠️ Fix Broken Links Without Leaving WordPress Finding broken links is only half the job. Broken Link Checker lets you fix them straight from the dashboard. Edit a link inline to point it at the correct URL, unlink it, or remove it, and the change is written back to your post automatically. You can clear out many broken links in a single sitting instead of opening each post one at a time. Broken links are also marked in red on the frontend with the Broken Links Highlighter, so they are easy to spot, and the plugin can stop search engines from following broken links while you work through them. If you use the AIOSEO Redirects feature, you can send a broken link straight to a working URL with a redirect. When a link redirects before it breaks, the report offers the end of the redirect chain as the replacement, so you can point the link at where it actually ends up in one click. 📬 Broken Link Reports by Email You should not have to remember to check a dashboard. Broken Link Checker emails you when something changes:

• A weekly email listing only the links that broke since the last report, so a quiet week means a quiet inbox.
• A monthly scorecard with your totals - links checked, broken, redirecting, and newly broken - plus what broke that month.

Add as many recipients as you like in the settings, and every email has a one-click unsubscribe link. 📤 Export Your Broken Links Export the report to CSV with one click. The file matches whatever filters and search you have on screen, so you can hand a client a list of exactly the broken external links on their site, or work through a long list in a spreadsheet. Every row carries where the link was found and why the check failed. 🏢 Who Uses Broken Link Checker Broken Link Checker works for any WordPress site that links out or links internally:

• Bloggers and publishers - keep years of posts free of dead links and broken video embeds.
• eCommerce stores - catch broken product links, broken images, and supplier URLs.
• Affiliate marketers - find broken affiliate links before they cost you commissions.
• Agencies and freelancers - monitor client sites and fix broken links from one place.
• Local businesses - make sure menu, booking, and map links keep working.

🛡️ Built by the Team at AIOSEO Broken Link Checker is built by AIOSEO, the team behind the All in One SEO plugin used on more than 3 million WordPress websites. The same focus on practical, results-driven SEO goes into keeping your links healthy and your visitors out of 404 pages. 🔎 A Better Way to Check Broken Links Than Ahrefs, Screaming Frog & Other Tools If you have looked for a way to find broken links, you have probably tried tools like Ahrefs, Screaming Frog, Dr. Link Check, or Dead Link Checker. Those tools can crawl a site, but they run outside WordPress, so you copy URLs back and forth and fix every broken link by hand in the editor. Broken Link Checker by AIOSEO lives inside your WordPress dashboard. It finds broken links, broken images, and dead video links, and it fixes them in place. Because the scanning runs in the cloud, it does this without loading your server the way an on-site crawler plugin does. Credits This plugin is created by Benjamin Rojas and Syed Balkhi.

New in Version 1.3.1

• New: Links are now found outside post content - in custom fields (including ACF), navigation menus, category and tag descriptions, author bios and websites, post excerpts, and the block content the editor stores outside your posts such as synced patterns, templates, template parts and navigation blocks.
• New: Page builder support - links inside Elementor, Divi (4 and 5), WPBakery Page Builder, SiteOrigin Page Builder, Avada Builder and SeedProd layouts are now found and reported, including the pictures a block or a section background points at.
• New: Broken link reports by email - a weekly email listing the links that broke since the last report, and a monthly scorecard of your site's link health, sent to the recipients you choose.
• New: The report is now organised around where each link was found, with every location for a link listed and paginated inline, and a filter to narrow the report to one source - offering only the sources that actually hold links.
• New: Filter the report by internal or external links, and by images, videos or non-media links.
• New: Export the report to CSV, matching the filters and search you have on screen.
• New: Exclude URLs by wildcard, by host, or by regular expression, in a single exclusion list.
• New: Added a scan frequency setting to control how often links are rechecked.
• New: Added per-source scanning settings, so you choose which places are monitored - navigation menus, custom fields, term descriptions, author bios and websites, synced patterns and templates.
• New: When a broken link redirects, the report offers the end of the redirect chain as the replacement.
• New: Audio files, and the images that core blocks keep in a block attribute, are now reported.
• New: Added Site Health checks that report when link monitoring has stopped, and an admin bar warning when the account is not connected.
• New: A dashboard - it opens on what to do next rather than on a list of everything that is wrong. Its main panel ranks the fewest fixes that clear the most broken links: one dead address used in many places, a whole host that has gone, a page carrying several at once, broken images and videos. Alongside it, why your links are failing, the domains costing you the most, how long each has been broken, and where on your site they live. Every figure opens the report already narrowed to it.
• New: The Broken Links Highlighter can be switched on and off from the toolbar while you are looking at a page, and each person can turn it off for themselves without changing it for anyone else.
• New: Multisite support - the network admin has its own Site Activations screen, where you connect the network's license once and then activate or deactivate the individual sites on the network from a single list.
• New: Registered the plugin's abilities with the WordPress Abilities API.
• New: A destination whose SSL certificate has expired, or does not match, is now reported as broken. These answer a link check normally, so the report used to call them working links while a browser stops your visitors with a warning screen.
• New: Videos embedded as an iframe - pasted in as HTML, or written by a page builder - are now checked, so a video that was taken down no longer leaves a dead player on the page with nothing said about it.
• New: The CSV export has a Reason column, so a row reading "Broken" beside a working status code explains itself in a spreadsheet.
• New: The dashboard says how many links are still waiting for a verdict, next to the counts they are missing from, and the monthly email names what they are waiting for rather than giving one reason for all of them.
• Updated: The highlighter now explains a broken link where you find it. Hovering a marked link shows what it points at, why the check failed, and a note that only logged-in editors can see the marks - along with where to turn them off. The panel stays open while you move the pointer onto it.
• Updated: The Broken Links Highlighter is now on by default.
• Updated: The report shows how long each link has been broken and can be sorted by it, so the breakage that has been live longest is easy to find.
• Updated: The Broken Link Checker widget on your WordPress dashboard now shows the single most useful thing to fix, rather than a chart of your link totals.
• Updated: AIOSEO's Details column now marks broken links with a broken chain icon and links the count straight to the rows behind it, for any post title.
• Updated: AIOSEO's 404 log now shows how many of your posts link to each 404'd URL.
• Updated: Rewrote the email template so it renders correctly in Outlook, Gmail, and clients that invert colours.
• Updated: The broken links report is substantially faster - counts are cached, rows no longer cost a query each, and paging no longer recounts the whole table.
• Updated: Every source is now indexed regardless of the settings, so switching a source on shows its links immediately instead of waiting for a full rescan. Switching one off no longer deletes anything.
• Updated: A synced pattern, template or navigation block is reindexed as soon as it is saved, so a link you fix there leaves the report right away.
• Updated: A synced pattern is only editable from the report by someone who can edit that particular pattern, since a pattern belongs to whoever created it.
• Updated: Removing a URL exclusion now restores the links it had removed from every source, not just from posts.
• Updated: An action a source cannot perform now explains why on hover instead of quietly disappearing.
• Updated: An image's alternative text is not something the report can rewrite, and it now says so instead of appearing to save the change.
• Updated: Replaced the link status details modal with an inline panel that states exactly what a change will affect.
• Updated: Elementor pages no longer report the same link twice, a page built with a builder is reported as a page, and a builder that is no longer active stops being reported.
• Updated: The report can now be sorted by when each link was last checked.
• Updated: Reorganised the settings - the link settings have their own section, the Advanced Settings master switch is gone, and scan sources use the same post type toggles as the rest of the plugin.
• Updated: Your link quota is now explained where it is shown, and turns red as it approaches the limit.
• Updated: Improved the account connection and activation prompts, and added a newsroom panel for plugin news.
• Updated: The report now says why a check failed rather than only that it did. A destination that blocked the check, one that did not respond in time, one that could not be reached at all, one whose address cannot exist, and a page that is there and asks to be signed in to each read differently, instead of all of them showing the same error. The last of those is the one worth calling out: a link wanting a login used to be reported as an error, which sent you looking for a fault in an address that is fine.
• Updated: No Broken Link Checker JavaScript is loaded on admin screens that do not need it. A small script used to run on every page in the dashboard to style one menu item, which is now done in CSS.
• Updated: The highlighter now marks broken images, frames and embedded players. They have no text to underline, so they take a dashed outline drawn inside their own box, and a player is outlined when one of the sources behind it is broken.
• Updated: A link whose address holds a character no browser accepts is now marked by the highlighter in Firefox and Safari as well as Chrome, and is reported rather than quietly dropped from the scan.
• Updated: The scan no longer waits out its idle timer when links fall due inside it, so a post you save, an import, or a plugin update is picked up straight away instead of up to an hour later.
• Updated: Broken Link Checker now requires PHP 7.4 or higher.
• Updated: The report no longer offers to move a post to the trash. Edit or unlink the broken link instead.
• Fixed: Dismissed links were counted and listed under the Pending filter, so the filter counts did not add up to the total.
• Fixed: A link could be counted and listed under two filter tabs at once, so the tabs added up to more than the total. A link that had ended up with two check records behind it is now repaired, and the scan no longer creates them.
• Fixed: A link edit that changed nothing reported success, closing the panel over content that still carried the old URL.
• Fixed: Searching the report treated an underscore or a percent sign in a URL as a wildcard, so a search could match links that did not contain it.
• Fixed: Relative link URLs are now kept relative when they are sanitised.
• Fixed: On some sites a script error broke the post editor, and the plugin was not the obvious cause because the error named an AIOSEO object. The script no longer depends on data a page may not have printed.
• Fixed: A recheck the service refused - an unverified license, or a month of link checks already used - advised trying again, which could never work. It now says what actually happened.
• Fixed: Two links whose addresses differ only in capitalisation were treated as one. The filter tabs added up to more than the total, and one of the pair was counted but never listed, exported, or fixable from the report.
• Fixed: The email report counted a link that redirected and then broke as both broken and a redirect, where the report on screen counts it as broken only.
• Fixed: Editing a link did nothing for an address the scan had tidied up on the way in - surrounding spaces, a backslash in place of a slash, a default port, a dot segment, a non-English path - which is the shape a broken link is most likely to have been written in.
• Fixed: Editing a link could not rewrite the address on an iframe, video or audio tag, and it dropped the part after the # from a link that had one, so two links pointing at different places on the same page were both sent to the same place.
• Fixed: Editing a link whose anchor text begins inside the surrounding HTML could damage the markup around it.
• Fixed: A post dated in the future - a scheduled post, or content an importer forward-dated - was re-read on every scan and never settled, so the scan never got as far as your menus, custom fields, term descriptions, author profiles, patterns and templates.
• Fixed: The second-opinion recheck kept picking the same few links every run, so the rest of the queue was never reached and a dead host never settled.
• Fixed: A link our service could not fetch was never rechecked from your own site, so it never resolved, was counted against your credits on every scan, and could settle as a working link.
• Fixed: A link that failed every recheck kept the status code the service had last seen, so a row could read "the destination returned a 200 error".
• Fixed: Searching the report for something that matches nothing listed every link instead of none.
• Fixed: The Activate button was live with the license key field empty, and pressing it answered "an unknown error occurred" rather than asking for a key.
• Fixed: Addresses that 1.3.0 stored in a mangled form - two links glued into one, a host with the path run into it - are re-read when you upgrade instead of staying in the report as broken.
• Fixed: An excluded post recorded by anything other than the settings screen could stop the scan with a fatal error.
