How to Fix Broken Links in Blog Posts: The Complete 2026 Guide

Broken links are hyperlinks that lead to pages that have been deleted, moved or are otherwise unreachable. When users click on a broken link they’re met with a 404 or similar error, which hurts trust and makes your blog feel outdated. Although Google has said that 404 errors are normal and don’t directly penalize your rankings, they weaken internal linking and can waste crawling resources. Fixing them improves user experience, preserves link equity and ensures visitors—and search engines—can navigate your content smoothly.

Why Broken Links Matter for SEO and UX

Search engines use links to discover and index your pages. When links break:

• Crawl paths break – internal links that lead nowhere make it harder for crawlers to find your important pages.
• Link equity leaks – outbound links that return 404 errors waste the “vote” you are passing to another page and fail to provide value.
• Poor user experience – visitors who hit dead ends are more likely to leave your site and less likely to trust your content.
• Soft 404 risk – redirecting every missing URL to the home page or serving a 200 status for a missing page can confuse search engines. Google discourages this practice; missing pages should return proper 404/410 codes.

In short, while having some broken links won’t get you penalized, cleaning them up keeps your blog professional and makes it easier for people (and bots) to engage with your content.

Best WordPress Plugins for Finding and Fixing Broken Links

Broken Link Checker by WPMU DEV

WPMU DEV’s Broken Link Checker is one of the most popular link‐monitoring plugins and was listed with 650 000+ active installations on WPMU DEV’s free plugins page. The plugin runs either locally on your server or via a cloud engine. The cloud engine scans up to 20× faster, offloading the heavy crawling to WPMU DEV servers so it doesn’t slow down your site. Local scans run directly in the WordPress dashboard for those who prefer not to connect to external servers.

Key points:

• Edit or unlink links from the dashboard – you can update the broken URL or unlink it altogether without editing each post manually. There is no feature to add rel="nofollow" tags, despite some older blog posts claiming so.
• Cloud vs. local scanning – cloud scanning is faster and reduces server load; local scanning runs on your site for complete privacy.
• Free Hub restrictions – free users must wait 15 minutes between manual scans; upgrading removes the cooldown.
• Multisite support – the cloud version works on the network’s main site, while subsites use the local engine.

Overall, Broken Link Checker is ideal for WordPress users who want a set‑and‑forget solution with both manual and automated scanning. Remember to enable the cloud engine if your host restricts resource‑heavy plugins.

AIOSEO Broken Link Checker

AIOSEO offers a SaaS‑powered broken‑link checker. Unlike traditional plugins, it runs on AIOSEO’s servers, so it won’t consume your hosting resources. After installing the plugin you create or connect an AIOSEO account; the free tier scans up to 250 internal links per month and larger sites need a subscription.

Features include:

• Monitors internal and external links and reports valid links, redirects and broken links.
• Granular control – choose which post types and statuses to monitor and exclude specific URLs.
• Scheduled scans – checks run automatically at regular intervals.
• Inline editing – update broken links from within the plugin’s interface.
• SaaS architecture – scanning happens on AIOSEO servers, preventing IP blocks and host resource issues.

AIOSEO’s broken‑link checker is great for users already in the AIOSEO ecosystem who want off‑site scanning and a simple, report‑driven interface.

Rank Math 404 Monitor & Redirections

Rank Math doesn’t scan every post for broken links; instead it focuses on 404 monitoring and redirect management. The 404 Monitor module logs each 404 error, including hit count, last accessed time, referrer and user‑agent. You can switch between simple and advanced modes, filter out unwanted patterns and clear logs when you’ve fixed the errors.

Pair the monitor with Rank Math’s Redirection module (or the standalone Redirection plugin) to map dead URLs to new destinations. Rank Math is perfect for users who already rely on it for SEO and want to capture 404 errors within the same dashboard. Just remember it’s not a full site‑wide broken link scanner—it tracks only URLs that visitors or bots hit.

Redirection Plugin

Redirection is a free and widely used WordPress redirect manager. It lets you create 301 redirects without any server configuration and supports regex patterns, query‑string handling and conditional redirects. The plugin can watch for permalink changes and automatically create redirects for updated slugs.

Other notable features:

• Track 404 errors – Redirection logs all 404 events so you can spot problematic URLs and create redirects.
• Full logging and analytics – see who triggered a redirect or 404 (IP, browser, referrer) and export logs for analysis.
• Conditional redirects – redirect users based on login status, capability, referrer, cookies, browser or other conditions.
• Import/export and server support – export rules to Nginx or Apache, import from other plugins and manage redirects via WP‑CLI.

Use Redirection alongside a scanner like Broken Link Checker to fix dead links systematically.

Yoast SEO (Premium)

Yoast SEO is a powerful SEO toolkit, but it does not include a full broken‑link checker. Yoast’s guides recommend using analytics, Google Search Console and other tools to find 404s. The premium plugin offers a redirect manager and internal linking suggestions, but you’ll still need a dedicated scanner or 404 monitor to locate broken links. For complete link audits, pair Yoast with Broken Link Checker or a site‑wide crawling tool.

External Platforms for Link Checking (Off‑Site Scanning)

Semrush Site Audit

Semrush’s Site Audit is a comprehensive SEO crawler. Once you set up a project and run a crawl, it lists every internal and external link that returns an error, along with the pages where those links appear. You can filter issues by “broken internal links” or “broken external links,” inspect HTTP status codes and export the data for bulk fixes. This tool is ideal for bloggers and businesses who want a deeper technical audit beyond WordPress.

Ahrefs Broken Link Checker and Site Audit

Ahrefs provides a Broken Link Checker powered by its large backlink index. It instantly lists every broken outbound link on your site and lets you filter and sort results. You can schedule daily, weekly or monthly crawls to discover new dead links and export reports in CSV format. Ahrefs also identifies dead pages on your domain (broken internal links) so you can reclaim link equity by reinstating or redirecting those pages. The tool runs in your browser and doesn’t require installing anything on your site.

Screaming Frog SEO Spider

Screaming Frog is a desktop‑based website crawler for Windows, macOS and Linux. The free version lets you crawl up to 500 URLs per crawl. Once you load your website, it identifies broken links (404s) and server errors, lists the source pages and lets you export the results for fixing. The tool also audits redirects, titles, meta data, duplicate content and over 300 other SEO elements. Because it runs locally, it’s a great option when you need a thorough audit without relying on cloud services.

BrokenLinkCheck.com

BrokenLinkCheck is a free web‑based service for quick audits. It checks internal and external links and highlights the exact HTML line where a link is broken. The site advertises scanning an unlimited number of pages, but the free edition is capped at 3 000 pages per scan. It’s perfect for spot checks or smaller sites; larger sites can opt for the paid version to remove limits.

Performance Considerations

Running large scans on shared hosting can strain resources. Some managed hosts (e.g., WP Engine or GoDaddy) block resource‑heavy local scanners. Using cloud‑based scanners like WPMU DEV’s cloud engine or AIOSEO’s SaaS avoids performance issues. If you opt for local scans, schedule them during off‑peak hours and keep an eye on server load.

For very large sites or technical audits, consider off‑site tools like Semrush, Ahrefs or Screaming Frog, which handle the crawl externally and then let you apply fixes in WordPress.

Step‑by‑Step: Fixing Broken Links

1. Identify and categorize broken links – Run a scan with your chosen tool. Export or note which links are broken and classify them as:
   • Internal links to deleted or moved pages
   • External links to pages that no longer exist
   • Typos or malformed URLs
   • Redirect loops or chains
2. Decide on the fix:
   • Update the URL if the correct page still exists (e.g., the slug changed).
   • Create a 301 redirect when a page was deleted or moved; redirect to the most relevant page to preserve link equity.
   • Remove or unlink the reference when no suitable replacement exists.
   • Replace with an alternative source when an external link is dead.
3. Implement and test – Use your CMS or a redirect plugin like Redirection to set up redirects. Spot‑check a sample of fixed links manually. Use your scanner to verify that errors return the correct status codes (for example, a deleted page should return 410 rather than 302).
4. Monitor continuously – Enable scheduled scans (weekly or monthly) and set up email notifications so you’re alerted when new broken links appear. In WordPress, keep the 404 monitor and redirect manager running to catch incoming errors. In external tools, schedule recurring crawls.

Preventing Future Broken Links

• Use relative URLs for internal links (e.g., /about instead of https://example.com/about). This avoids issues if you change domain or move between HTTP and HTTPS.
• Double‑check external links before publishing – open each link in a new tab to confirm it works.
• Avoid linking to temporary resources – campaigns, short‑lived promotions or pages likely to disappear soon.
• Archive critical external resources – use the Wayback Machine to save snapshots of essential pages for citation.
• Maintain a regular content audit schedule – review your most important posts quarterly or at least annually, update information and run a link check.

Broken links often happen when bloggers rush the setup process — which is why I recommend following a complete step-by-step blogging guide before installing plugins or publishing content.
