getting increase in 404 errors on wordpress site message from google

Can you please tell me what can cause this message on a wordpress site?

Increase in “404” pages on

To: Webmaster of,

Googlebot for smartphones identified a significant increase in the number of URLs on that return a 404 (not found) error. If these pages exist on your desktop site, showing an error for mobile users can be a bad user experience. This misconfiguration can also prevent Google from showing the correct page in mobile search results. If these URLs don't exist, no action is necessary.

Recommended Actions:

Identify the URLs with errors
Open the Smartphone Crawl Errors report in your Search Console account to review the list of sample URLs.
Check Smartphone Errors
Fix the issue
If these pages exist for desktop users but not for smartphones, allow smartphone users to view the appropriate desktop pages. If no equivalent desktop page exists, no action is necessary. Returning a 404 Not Found result code is fine for pages that don't exist. If other sites link to these non-existent pages, consider contacting them or redirecting to the appropriate page on your site, if possible.
Verify the fix
Once you've fixed the URLs with errors, make sure that Googlebot for smartphones can access and see your content properly, or that they return a proper error result code. Use Fetch as Google with the "Mobile: smartphone" option enabled.
Fetch as Google

    Hi cornelius_butler !
    Hope you are having a great day!

    Well, this is not a very unusual issue. Webmaster usually shows a lot of data which are not actually updated to the present point of your site. To get more explanation and instructions about this errors, you may refer to this article. This usually happens when you have trashed a page or post from your site but the crawlers can still find the link to that page/post in external sites. First of all you need to find the links Webmaster is referring to in your Smartphone Crawl Errors report in your Search Console account. The instruction simply says,

    If these URLs don't exist, no action is necessary.

    So if you don't have those links in your site, you don't have to do anything.

    Hope this helps. I'll be looking forward to hearing from you about the error reports in your Search Console. Thanks!
