Crawlers waste budget trying to access non-existent pages, which delays indexing of your real content. Google has confirmed that excessive 404 errors can negatively impact crawl efficiency and site quality signals.

Frequently asked questions
How do broken links affect SEO?
Broken links create 404 errors that waste crawl budget, increase bounce rates, and signal poor site quality to search engines. Excessive broken links can negatively impact your rankings.
What is a soft 404?
A soft 404 occurs when a page returns a 200 OK status but shows a 'not found' message. Search engines treat these as errors. Our tool can detect soft 404 patterns.
How often should I check for broken links?
Monthly for most sites. Check more frequently if you publish new content regularly, have many external links, or recently migrated your site.
Should I redirect all 404 pages?
No. Redirect only when a relevant alternative exists. For pages with no equivalent, let them 404 so Google can crawl and remove them from the index.
Can broken links on other sites hurt me?
No. Broken inbound links from other sites don't harm your SEO, but they mean you're missing out on potential link equity. You can't control external sites, but you can fix your own.
