Broken Link Detection
Before They Hurt Rankings

TechySEO continuously monitors every internal link, external link, and resource reference on your website. The moment a 404 error appears β€” whether from a deleted page, a changed URL, or a dead external resource β€” you're alerted before it damages user experience or wastes crawl budget.

Broken Links Silently Destroy Rankings and Revenue

Broken internal links interrupt the flow of link equity through your site. When Googlebot follows a link that returns a 404, it can't pass authority to the destination page β€” and it marks that URL as an error in your crawl log.

For eCommerce sites, a broken product link means lost sales. For publishers, broken citation links erode credibility. For agencies managing client sites, a missed 404 detected by the client before you is a career-damaging moment.

TechySEO's continuous crawler detects new 404 errors as soon as they appear β€” not weeks later during a manual audit. Every broken link comes with the exact source page, anchor text, and HTTP response code.

πŸ“‰
Lost Link Equity
Broken internal links stop PageRank from flowing to important pages, gradually weakening the authority of your most valuable content.
πŸ€–
Wasted Crawl Budget
Googlebot wastes crawl budget following 404 links instead of discovering valuable new content. On large sites, this measurably reduces indexing rates.
😀
Poor User Experience
A user clicking a link and landing on a 404 page is a conversion-killing dead end. High 404 rates increase bounce rates and send negative UX signals.

Content Sites

CMS Migrations & Restructures

URL restructures, category merges, and CMS migrations leave broken links everywhere. TechySEO catches every missed redirect immediately after launch, before traffic is affected.

Deliver monthly reports showing zero unresolved broken links across client sites. Use TechySEO's broken link data in client retention conversations as proof of proactive monitoring.

Common Questions

Does TechySEO check external (outbound) links too?
Yes. TechySEO checks both internal and external links. For external links, it makes HTTP HEAD requests to verify the destination is still live, returning a valid 2xx status. Broken external links (404, 410, connection refused) are reported separately from internal ones with their source page and anchor text.
What's the difference between a 404 and a 410 status?
A 404 means "Not Found" β€” the server can't find the page but it may return in the future. A 410 means "Gone" β€” the resource has been permanently removed. Google treats 410s as a stronger signal to deindex the URL faster than a 404. TechySEO reports both, with the specific status code for each broken link.
How quickly does TechySEO detect new broken links?
Detection speed depends on your crawl plan and site size. On Growth and Scale plans, frequently visited pages are recrawled every few hours, so new broken links on high-traffic pages are typically detected within 1–6 hours of appearing. You can also manually trigger a recheck on specific URLs instantly.
Can I export the broken links report?
Yes. The broken links report can be exported as CSV (all plans) or PDF (Starter and above). Exported data includes: source page URL, broken link URL, anchor text, HTTP status code, first detected date, and current status. Useful for sending fix lists to development teams.
Does it check broken links in JavaScript-rendered content?
Yes. TechySEO uses headless browser rendering, so links that are injected by JavaScript frameworks (React, Vue, Angular) after page load are discovered and checked just like statically rendered links. This is critical for SPAs and JavaScript-heavy eCommerce platforms.
