Soft 404's on a 301 Redirect...Why?

[MJTrevens]

So we launched a site about a month ago. Our old site had an extensive library of health content that went away with the relaunch. We redirected this entire section of the site to the new education materials, but we've yet to see this reflected in the index or in GWT. In fact, we're getting close to 500 soft 404's in GWT. Our development team confirmed for me that the 301 redirect is configured correctly.

Is it just a waiting game at this point or is there something I might be missing?

Any help is appreciated. Thanks!

Mememax,  thank you.  I did not know this.

Have you tried the Custom 404 Widget?

Yes that happened to me a couple of years ago too.

If you're redirecting a lot of different content to the exact same generic page (like a section/category homepage) google will consider that the page is like a container, not the location where that exact content was moved. A clear signal for them would be that they can't find any portion of the old content.

Here you can read some guidance from google regarding returning 404s. It seems that mask 404 witha 301 is not the way to go anymore, just limit that to pages with backlinks pointing there, because if not you can just return 404 and delete those pages from google index (you don't want google to waste your crawl budget on those pages).

Hope this helps!
