A common question among search optimizers is whether a \u201c404\u201d HTTP status code conveys negative ranking signals for the site as a whole.<\/p>\n
The answer is yes, but indirectly.<\/p>\n
Impact of 404s<\/h3>\n
For starters, a 404 error<\/a> is not a direct<\/em> ranking signal. Broken links or deleted pages do not impact sitewide rankings in Google search results. Former Google Webmaster Trends Analyst Susan Moskwa confirmed this in 2011<\/a>. She called 404 errors a natural occurrence on the web, one that search engines are aware of.<\/p>\n She also stated that Google prefers 404 status codes (or 410s for pages intentionally removed) because they clearly inform<\/a> that the page is unavailable.<\/p>\n Google\u2019s Search Console guidelines<\/a> also address 404s, stating they \u201cwon\u2019t impact your site\u2019s search performance.\u201d<\/p>\n Google\u2019s John Mueller recently confirmed this on Reddit<\/a> (\u201cjohnmu\u201d ): \u201cJust to be clear: 404s\/410s are not a negative quality signal. It\u2019s how the web is supposed to work.\u201d<\/p>\n Yet 404 status codes can result in a loss of organic rankings through other signals:<\/p>\n Hence detecting and fixing broken links and deleted pages is a key step in diagnosing organic traffic drops<\/a>. I typically use three methods: Search Console, Google Analytics, and third-party tools.<\/p>\n Search Console\u2019s \u201cPages\u201d report includes unindexed URLs and the reasons, such as 404 and 410 status codes. Review the list and confirm:<\/p>\n Search Console\u2019s \u201cPages\u201d report includes unindexed URLs and the reasons.

View the page title. (Bookmark the page, view the title in \u201cEdit bookmark\u201d or similar.)<\/p>\n In my case, it\u2019s \u201c404 \u2013 Page Not Found.\u201d<\/p>\n View the page title, such as \u201c404 \u2013 Page Not Found\u201d in this example.<\/p>\n<\/div>\n Next, go to the \u201cPages and screens: Landing page\u201d report in Google Analytics:<\/p>\n Go to the \u201cPages and screens: Landing page\u201d report on Google Analytics. Click image to enlarge.<\/em><\/p>\n<\/div>\n Platforms such as Ahrefs and Semrush can identify external links<\/a> pointing to error pages on your site. Access Semrush\u2019s tool in the \u201cBacklink Audit\u201d section:<\/p>\n The Semrush report shows the number of domains linking to each broken page. Ahrefs\u2019 report is similar.<\/p>\n Web crawlers<\/a> such as Screaming Frog can identify broken internal<\/em> links.<\/p>\n\n
