Few things worry site owners as much as a long list of 404 errors in Search Console. Google has tried to calm that fear for years, and in a Halloween episode of its Non-Canonical Cabinet video series, published on October 28, 2026, Gary Illyes and Cherry Prommawin said it again: 404s are a normal part of the web, not an SEO emergency.
What Google said
- No penalty. Google does not penalize sites for 404 errors. Missing URLs eventually drop out of the index, and a 404 does not harm the healthy pages on the site.
- Fixing is optional. “Fixing a 404 is entirely optional,” Illyes said. It is a business and user-experience decision, not an SEO requirement.
- No crawl budget drain. “A 404 error does not drain your crawl capacity.” Server errors (5xx) and 429 “Too Many Requests” are different: they can make Google slow down crawling.
- Don’t redirect everything to the home page. Sending unrelated dead URLs to the home page confuses visitors and distorts your data.
Google’s three-step framework for dead URLs
- 1. Redirect when there is a real replacement. If a page moved or a close equivalent exists, a 301 redirect sends users and signals to it. Check redirects with our Redirect Checker and read 301 vs 302 redirects.
- 2. Return 404 or 410 when it is gone for good. If there is no replacement, let the URL return 404 (not found) or 410 (gone). Both tell Google to drop it.
- 3. Make the 404 page useful. A clear message, a search box and links to popular or related content keep visitors on the site.
How to triage the 404 list in Search Console
Not every URL in the “Not found (404)” report deserves attention. Look at each one through four questions:
- Does it get traffic? Check analytics for visits to the URL. A 404 that real people land on is worth fixing.
- Does it have backlinks? External links to a dead URL lose their value. Redirecting it to the right page keeps it.
- Is it important for the business? A product, category or landing page that disappeared by mistake should come back or redirect.
- Is there a real replacement? If not, a 404 is the correct answer, even if it stays in the report.
Many 404s in Search Console come from old URLs, typos in other sites’ links or URLs Google found in scripts. Those can usually be ignored.
The errors that do matter
- Soft 404s: pages that say “not found” but return a 200. Google may treat them as errors anyway, and they waste crawling. Return a real 404 status instead. Check the status code with our HTTP Header Checker.
- Server errors: many 5xx responses slow crawling for the whole site. During maintenance, use a 503 the right way.
- Broken internal links: links on your own pages that point to 404s waste crawl paths and frustrate users. Fix the link, not just the target.
Frequently asked questions
Frequently asked questions
Do 404 errors hurt SEO?
No. Google says 404s don’t cause penalties and don’t harm healthy pages. The missing URL simply drops out of the index.
Should I redirect all 404 pages to the home page?
No. Google discourages it: redirect only when there is a relevant replacement, otherwise return 404 or 410.
What is the difference between 404 and 410?
Both tell Google the page is gone. 410 states more explicitly that the removal is permanent; Google treats both as signals to drop the URL.
Do 404s waste crawl budget?
No. Google says a 404 does not drain crawl capacity. Server errors and 429 responses can slow crawling.
