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. 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. ☁️ 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 specific URLs and domains so your broken link report stays accurate. 🛠️ 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. 🏢 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.
