One of my websites has 131 soft-404 error pages listed in Google Search Console. Those pages are full of content and have changed recently. However, Google Search Console still says that the pages are soft-404 errors.
I've reviewed this article but still don't know how to resolve the issue. Search Engine Journal -- 404 vs Soft 404 Errors: What’s the Difference & How to Fix Both According to it.
Soft error 404 is causing due to duplicate content/thin content.
There are some servers that are poorly configured and their missing page loads a 200 code when it should display a 404-response code. If the invisible HTTP header displays a 200 code even if the web page clearly states that the page isn’t found.
My website pages have content that is unique and the server details are configured properly.
