Check for Broken Links – Broken Link Checker & SEO Suite vs Custom 404 Error Page

Find broken links, 404 errors & broken images. Internal link optimizer, rank tracking, AI visibility, SEO audits and uptime monitoring in one plugin. Broken Link Checker for WordPress: Find and Fix Broken Links Fast Check for Broken Links scans your entire WordPress site for broken links, dead links, 404 errors and broken images. It shows you exactly where each broken link was found so you can fix it fast. Your site breaks quietly while you are busy. Pages get deleted, plugins get abandoned, external sites go offline. Google finds the 404 errors before you do, and your rankings pay the price. This plugin finds every broken link across your posts, pages, custom post types and slider content, and Pro extends the scan to comments and custom fields. Unlike external link checker tools, the plugin runs inside WordPress. It scans private content, drafts and pages behind login that no external crawler can reach. Version 3 adds five more tools to the same plugin. You can now track your keyword positions, watch how AI assistants mention your brand, repair your internal linking, audit your site for SEO and AEO, and monitor uptime. All of it runs in wp-admin. See the section below. How It Works Install and scan. Run your first manual scan in seconds and see every broken link on your site. Set your schedule (Pro). Choose daily, weekly or monthly scans.

Filter results by link type, content type and error status such as 404, 403 or 500. Export everything to CSV. The plugin never changes your content automatically, so you stay in full control.

More about the Keyword Rank Tracker and the dedicated Bing Rank Tracker. AI Visibility Tracker People now ask ChatGPT, Perplexity and Google AI Overviews the questions they used to type into Google. This tracker shows you the answers. You add the prompts your customers actually use, and the tracker checks them weekly to see whether your site gets mentioned or cited. One credit tracks one prompt. Business and Agency plans include 10 credits, and larger packs are available for any plan. The plugin opens your project’s prompt tracking straight from the sidebar. More about the AI Visibility Tracker Internal Link Optimizer Some of your pages have no internal links pointing to them. Search engines rarely find those orphan pages, and they almost never rank. This tool maps the links between your own pages, lists the orphans and suggests which posts should link to which, with anchor text written by AI. Internal links pass ranking value between your pages. Fix the gaps and your strongest pages start lifting the weaker ones. More about the Internal Link Optimizer SEO / AEO Audit Run a full audit of your site and get a fix list sorted by impact. The audit covers technical SEO, on-page factors and how well your content answers questions in Google and Bing. AEO means Answer Engine Optimization. It covers the parts that decide whether AI assistants quote your content: clear headings, structured data, direct answers and clean markup. The audit scores both sides and tells you what to fix first. Every plan includes monthly audits, from one on Free up to 25 on Agency. More about the SEO / AEO Audit Uptime Monitor A site that is down earns nothing and ranks worse. The Uptime Monitor checks your site from outside and reports incidents and response times inside wp-admin. One click adds a monitor for your connected site. Email alerts go out the moment your site stops responding, and you set the alert address and sensitivity in the plugin. It also watches WP-Cron with a separate heartbeat monitor. WP-Cron runs your scheduled jobs, and on many hosts it fails without a word. The plugin gives you a paste-ready snippet for it. Check frequency depends on your plan. More about the Uptime Monitor Pro Version: Set It Once, Forget It Pro turns the plugin from a checker into a monitor. It runs automatic scheduled scans, emails you the moment a link breaks, and helps you repair links with AI. Pro is included in every Broken Link Checker plan, starting at $49 per year. Pro features: Everything in Free Automatic scheduled scans (daily, weekly or monthly) Choose your scan time and timezone Email reports the moment broken links are found, to one or more recipients Notify post authors about broken links in their own content All-clear reports when no broken links are found Scan comments and custom fields, including ACF Fix with AI: finds a verified working replacement for each broken link Nofollow broken links until they are fixed Auto-fix permanently redirected URLs Replacement suggestions from the Wayback Machine Export as XLSX, TXT, PDF and Markdown for AI 50 to 1,000 rank-tracked keywords AI Visibility credits on Business and Agency plans Internal Link Optimizer 5 to 25 SEO / AEO audits a month Uptime monitoring with email alerts SEO optimized report page Priority support Plans for 1, 5 or 250 sites What Users Say “Simple but effective and works as it should” – @snappaguy “In 10 minutes did my first check and found and fixed my broken links.” – @rguiffrey “No membership, no cloud, no muss, no fuss. Just works.” – @eliyahna Why Fixing Broken Links Matters for SEO Every 404 error Google hits on your site signals poor maintenance. Broken links waste crawl budget, hurt user experience and damage rankings over time. Regular link checking keeps your site healthy in Google’s eyes. When a page is removed or a URL changes, set up a redirect to keep your link equity.
