Broken links: the error Google has spent 14 years saying isn't one

What Google has said, year after year

The earliest on-record version of this answer is from December 2012, when John Mueller addressed the question in a Google Webmaster Help forum thread, reported by Barry Schwartz at Search Engine Roundtable: “The number of crawl errors on your site generally doesn’t affect the rest of your site’s crawling, indexing, or ranking,” and “It’s completely normal for a site to have URLs that are invalid and which return 404 (or 410, etc).” Six years later, in a Google SEO Snippets video reported by the same outlet in March 2018, Mueller said almost the identical thing in almost the identical words: “Crawl errors for 404s that you don’t want to have indexed, don’t negatively affect the rest of your site in search,” adding that if nothing unusual shows up in the links or the traffic to a dead page, “having those pages returned 404 it’s perfectly fine.”

Fourteen years after his first answer, Mueller gave the same one again. Responding to a Reddit thread reported by Search Engine Roundtable on 2 January 2026, he said: “404s/410s are not a negative quality signal. It’s how the web is supposed to work.” Nine months later, Google’s Gary Illyes made the same point from the other side of the company, in a video reported by Search Engine Roundtable on 28 October 2026: a 404 carries “no penalty, no secret Google jail, and no negative impact on your other healthy pages,” because, as he put it, pages die, products sell out, and all URLs eventually get deleted. He added the crawl claim too: “A 404 error does not drain your crawl capacity.”

The one real exception: soft 404s

There is exactly one documented case where Google says a 404-shaped page does cost you, and it isn’t the error itself. Gary Illyes drew the distinction on Google’s Search Off the Record podcast, reported by Barry Schwartz on 29 August 2022: a genuine 404 or 410 status code doesn’t waste crawl budget, “neither do robotted URLs because we didn’t get back anything, just a status code.” A soft 404 is different. “If you do with, on the other hand, a soft 404, that’s a good job,” Illyes said, meaning the opposite of a compliment, because “you’re not putting anything in the index and wasted crawl budget.” A hard 404 tells Google plainly that a page is gone. A soft 404, a page that returns a 200 OK status while showing “page not found” text, or a site that quietly redirects every dead URL to its homepage instead of a real 404, tells Google the page is fine, at an address that has nothing worth indexing on it, and Google has to keep spending visits to find that out. Our guide to whether crawl budget still matters covers Google’s own documentation on exactly which categories of waste it is talking about, and why that waste costs an AI crawler running on a fraction of Googlebot’s budget far more than it costs Google itself.

Why “no ranking penalty” doesn’t mean ignore it

None of the quotes above are an argument for leaving broken links alone. They’re an argument for fixing the right ones instead of all of them. Mueller gave the actual filter in a Reddit thread reported by Search Engine Journal’s Roger Montti on 27 November 2023: “you don’t have to fix 404 pages, having things go away is normal & fine,” and, for most dead URLs, “the SEO ‘value’ of bringing a 404 back is probably less than the work you put into it.” His suggested test for which ones are worth the effort: find the broken links that still get real traffic, “which is probably a good proxy” for which ones are worth reclaiming. A page nobody links to and nobody visits costs you nothing by staying dead. Letting it 404 is also one of four legitimate remedies our guide to content pruning covers, alongside redirecting, noindexing and blocking a page outright. A page still carrying backlinks from other sites, or still showing up in your analytics as a 404 real visitors land on, is the one worth a 301 into the closest live equivalent.

What to check this week

1. Pull your actual traffic, not just a crawl list. Cross a site crawl of your 404s against Google Search Console’s Page Indexing report and your analytics’ landing-page data, the way Mueller’s own filter suggests, rather than trying to fix every dead URL a crawler happens to find.
2. Check whether your 404s are real 404s. Load a known-dead URL and confirm the server returns an actual 404 or 410 status code, not a 200 OK with “page not found” text or a blanket redirect to the homepage. The latter is the soft 404 Illyes specifically flagged as crawl-budget waste. Broken links spike hardest right after a redesign or domain move; our guide to the migration recovery timeline covers how long a rushed redirect map takes to resolve.
3. Redirect the ones with backlinks or real traffic, and let the rest die. A 301 into the closest live equivalent preserves the external links and traffic worth keeping. Everything else is, in Google’s own words, how the web is supposed to work.

What we could not verify

No independent study we could find measures a direct correlation between a site’s broken-link count and its rankings, the way a comparable, if flawed, study exists for accessibility. Google’s own repeated statements since 2012 are the only evidence on this specific question, and they are statements, not measured data. We could not find any restatement of Illyes’ soft-404 crawl-budget point newer than August 2022, so whether that guidance still holds in its original form rests on Google’s word from three years ago, not a current confirmation. And nothing in the sources here addresses whether a broken link changes how an AI engine like ChatGPT or Perplexity treats a page when deciding what to cite, a separate question this site has flagged as open territory elsewhere.
