Difference Between 404 error and Soft 404 error

[travelowebseo]

Soft 404 errors are much harder on your website's visibility than a hard 404 error. A “soft” 404 error happens when the wrong code (often the 200 response code) is returned by your server when someone tries to access a page that no longer exists on your site.
If the number of soft 404 errors is high, especially in comparison to the number of “real” pages on your site, it can have a negative impact on your organic search performance.

When everything is working the right way, your reader will see an error page, and your server will return a 404 or 410 response code. This lets both readers and crawlers know that the page doesn’t exist anymore and shouldn’t be indexed, and that page will be removed from search results over time.
