Tidy Broken Link Scan — WordPress Broken Link Checker Plugin

Why Broken Links Hurt Your WordPress Site

Broken links are one of the most common yet most damaging technical SEO issues a website can have. When a visitor clicks a link and lands on a 404 error page, the experience is immediately frustrating — they lose trust in your site, and most will simply leave. Studies show that broken links increase bounce rates by up to 30% and directly reduce the time visitors spend on your content. For sites that rely on affiliate revenue, advertising, or lead generation, every lost visitor translates to lost revenue.

From a search engine perspective, broken links send clear negative signals. Google's crawlers follow every link on your pages, and when they encounter repeated 404 responses, it indicates poor site maintenance. While Google has stated that a few broken links won't destroy your rankings, a pattern of link rot across your site will erode crawl efficiency, waste crawl budget, and weaken the internal linking structure that passes authority between your pages.

The problem is especially acute for content-heavy WordPress sites. After years of publishing, URLs change, external sites go offline, products get discontinued, and pages get reorganized. Without regular monitoring, broken links accumulate silently. By the time you notice the impact on traffic, the damage may already be significant. Proactive broken link detection is not optional — it's a core part of responsible site management.

How Tidy Broken Link Scan Works

Tidy Broken Link Scan scans your entire WordPress site from the inside. Unlike external tools — which crawl your site from the outside and are limited to publicly accessible URLs — this plugin reads directly from your WordPress database. It extracts every link and image URL from posts, pages, navigation menus, and optionally Advanced Custom Fields, then verifies each one with an HTTP HEAD request (falling back to GET when needed).

The scanning engine uses parallel HTTP requests (curl_multi) to check multiple URLs simultaneously, which means even sites with thousands of links can be scanned in minutes. As the scan runs, you see real-time progress: a progress bar, the total number of links found, and a live results table that populates as broken links are detected. There's no need to wait for the scan to finish — you can start fixing issues immediately.

Version 2.3 introduced auto-scan on post save: every time you publish or update a post, all links in that post are automatically verified in the background. If any broken links are found, you get a dashboard notification — continuous monitoring without any manual effort.

For complete coverage, pair the WordPress plugin with Tidy Broken Link Scan, a cloud-based scanner that crawls your site from the outside like Google does. The cloud scanner adds SSL certificate monitoring, sitemap validation, broken anchor detection, scan comparison over time, and Slack/webhook notifications — features that require an external perspective and are impossible for a WordPress plugin to provide. Together, they give you full-stack link monitoring: inside and outside, database and crawler, real-time and scheduled.

Advanced Link Health Features

Version 2.4 introduces several features previously only available in enterprise-grade tools. Broken anchor detection verifies that #section links (like /page/#pricing or /docs/#api) actually resolve to a matching element on the target page — a common source of user frustration after page redesigns that most link checkers completely ignore. Redirect chain detection flags URLs that pass through three or more redirects before reaching their destination, helping you clean up redirect chains that waste crawl budget and slow down page loads.

For teams, Slack notifications deliver a summary after every scheduled scan: total broken links, newly broken URLs, and recently fixed ones. Combined with the scan diff view — which highlights exactly what changed between two scans in a red/green format — you get a complete picture of your site's link health trajectory without ever opening the WordPress dashboard.
