Google to detect soft 404 error by device type

Google has modified the way it classifies soft 404s and now looks at a URL based on the device type. Now, if Google detects a URL and hits it on desktop before seeing it on mobile, it may send a soft 404 error for the desktop but not for the mobile devices. In other words, Google detects the soft 404 status on the basis of every URL, as well as by device type.

John Mueller, a Google Search Relations Advocate, lately verified that Google has modified how it handles soft 404 detection and classifications. The search engine now analyses each page based on the device it is being viewed on, and it may be possible to assign distinct soft 404 classifications to the same URL on mobile and desktop. This came to light after complaints were recorded in accordsnce to adjustments that the serach engine made over a month ago.

Let us simply break this down for you! A soft 404 normally occurs when a page returns an HTTP status code of 200 that further indicates that everything is fine. However, this page does not really load content or cannot be located, and plausibly produces a 404 error. When this happens, Google tends to mark these pages as soft 404s, and the URL is treated as a real 404, with the page not being indexed.

According to the complaints I’ve collected, this alteration occurred around a month ago. What happened? Google stated that it has modified the way it classifies soft 404s and now looks at a URL based on the device type. As a result, if Google detects a URL and hits it on desktop before seeing it on mobile, it may send a soft 404 for the desktop but not the mobile. In other words, Google detects the soft 404 status on a per-URL basis, as well as by device type.

A page can be returning fine for the mobile device type, and Google won’t show soft 404 errors in Search Console. Google only shows soft 404s errors based on the mobile crawl, so if the page works fine on mobile, Search Console won’t show an error. “In Search Console, we do show soft 404s but we show it for the mobile version. So if on the mobile version everything is okay on your side, then in Search Console it will look like its indexed normally. But for desktop, you won’t be able to see that directly in Search Console,” said Mueller.
