Question 1

What is a broken link and why does it hurt SEO?

Accepted Answer

A broken link (also called a dead link) is a hyperlink that points to a URL that no longer exists — returning a 404 Not Found or similar error. Broken links hurt SEO in two ways: (1) They waste crawl budget — Googlebot spends resources following links that lead nowhere instead of discovering new content. (2) They lose link equity — any PageRank flowing through a broken link is simply lost. Additionally, broken links create a poor user experience, increasing bounce rate and reducing trust. Google's quality guidelines explicitly mention broken links as a negative signal for site quality.

Question 2

How often should I check my website for broken links?

Accepted Answer

For most SaaS websites, checking for broken links monthly is a good baseline. However, after any of these events, run an immediate check: (1) Website migration or URL restructuring, (2) Deleting blog posts or landing pages, (3) Removing products or features from your site, (4) External sites you link to go offline or restructure. If your site has a large blog (100+ posts), set up automated monitoring with a tool like Screaming Frog or Google Search Console, which flags 404s in the Coverage report.

Question 3

What is the difference between a 404 error and a 410 error?

Accepted Answer

A 404 error (Not Found) tells search engines the page doesn't exist right now, but it might come back — Google will continue to check periodically. A 410 error (Gone) is a stronger signal that tells Google the page is permanently deleted and to remove it from the index immediately. For SEO purposes: if you've permanently deleted a page and are consolidating content elsewhere, use a 301 redirect to the new location. If the page is truly gone with no replacement, a 410 is marginally better than a 404 as it signals finality faster to Google.

Question 4

Do broken external links hurt my SEO?

Accepted Answer

Yes, but to a lesser degree than broken internal links. Broken external links (links pointing to other websites that have since gone offline) don't lose your own PageRank, but they do: (1) Create poor user experience when visitors click them, (2) Waste crawl budget as Googlebot follows them, (3) May be seen as a site quality signal by Google's quality systems. Best practice: when you find a broken external link, either remove it, update it to a working equivalent source, or link to a Wayback Machine archive if the content was important context for your article.

Question 5

How do I fix broken internal links in bulk?

Accepted Answer

The fastest way to fix bulk broken internal links: (1) Run this tool on your key pages to identify all broken links, (2) For deleted pages, set up 301 redirects from the old URL to the most relevant existing page (this recovers lost link equity), (3) For typos in links, update the href in your CMS or static files directly, (4) For pages you truly removed with no replacement, update all internal links to point to the parent category or homepage. If you're on WordPress, plugins like Broken Link Checker can scan your entire site and fix links from the dashboard. On static sites, a site-wide grep for dead URL patterns is fastest.

Question 6

What HTTP status codes mean a link is broken?

Accepted Answer

HTTP status codes that indicate a broken or problematic link: 404 Not Found — page doesn't exist (most common broken link). 410 Gone — page permanently deleted. 403 Forbidden — server refuses to serve the page (often blocks bots, may be fine for users). 500 Internal Server Error — server crashed. 503 Service Unavailable — server overloaded or down. 0 / Timeout — server didn't respond at all (domain may be expired). Redirect codes (301, 302, 307, 308) are not broken but may indicate link rot — links that once pointed directly to content now go through a redirect chain. For best SEO, update links pointing to redirected URLs to point directly to the final destination.
