Why are broken links bad for SEO?
Broken links waste crawl budget, frustrate users, and signal poor site maintenance to Google. Internal 404s prevent equity from flowing to deeper pages, while broken outbound links erode trust. Studies show users abandon sessions after one or two dead links, hurting engagement metrics that influence rankings. Search engines deprioritize sites that consistently send crawlers and users to dead ends, so a clean link graph is foundational SEO hygiene.
How often should I scan my site for broken links?
Run a full crawl monthly for active sites and weekly for high-publishing-frequency blogs and ecommerce stores. After major changes such as redesigns, CMS migrations, plugin updates, or content pruning, scan immediately because URL structure changes are the most common source of new 404s. Set a recurring calendar reminder; the cost of fixing 50 broken links found early is far lower than recovering rankings after months of decay.
What should I do when I find a broken internal link?
First check whether the target page was deleted intentionally or moved. If moved, update the link to the new URL or implement a 301 redirect from the old URL. If deleted, decide whether the destination should be restored, redirected to the closest equivalent page, or whether the source link should simply be removed. Avoid mass redirecting unrelated 404s to the homepage; Google treats those as soft 404s and ignores the equity transfer.
Should I redirect every 404 page on my site?
Only redirect 404s where a relevant replacement page exists. Letting truly retired content return a clean 404 is healthy and tells Google to drop it from the index. Redirecting every 404 to the homepage or to unrelated pages creates soft 404s that confuse search engines and disappoint users. Prioritize redirects for pages that have backlinks, organic traffic history, or matching replacement content; let the rest return 404 or 410.
Will fixing broken links recover lost rankings?
Often yes, especially when the broken links were on high-authority pages or were receiving direct organic traffic. Restoring equity flow can lift the affected pages within a few crawl cycles. However, broken links are usually a symptom of broader maintenance gaps; pair link fixes with content updates, internal linking improvements, and technical SEO clean-up for compounding ranking gains rather than expecting link fixes alone to rescue a struggling site.
Does this tool also find broken images and JavaScript files?
Yes, the crawler reports any 4xx or 5xx response on any asset URL referenced in the HTML, including images, scripts, stylesheets, and PDFs. Broken assets harm Core Web Vitals scores, layout stability, and user experience. A missing hero image can spike CLS and slow LCP, both of which Google uses as ranking signals. Treat asset 404s with the same urgency as broken page links during regular site audits.
