“404” is the HTTP status code denoting a page no longer exists, due typically to an error such as a broken or incorrect link. A common question among search optimizers is whether 404 errors convey negative ranking signals for the overall site.
The answer depends on the circumstance.
For starters, a 404 error is not a direct ranking signal. Broken pages do not impact sitewide rankings in Google search results. Former Google Webmaster Trends Analyst Susan Moskwa confirmed this in 2011. She called 404 errors a natural web occurrence that search engines are aware of.
She also stated that Google prefers 404 status codes (or 410s for pages intentionally removed) because they signal clearly the page is unavailable.
Google’s Search Console guidelines also address 404s, stating they “won’t impact your site’s search performance.”
Nonetheless, keep an eye on the Search Console “Pages” report, which includes unindexed URLs and the reasons, such as 404 status codes. (The report lumps 410 codes with 404s.)

The report is sorted by the number of domains linking to each broken page. Ahrefs’ option is similar.
