In my Search Console, I have some 404 links. Those links belong to pages that are deleted. I read online and realized that I should return 410 (Gone) for those pages. Yet Google Search Console does not recognize my 410 code and still shows 404 to me.
Even when I use START NEW VALIDATION 404 would be shown to me.
So, why Google Search Console does not recognize my 410 codes?
And do I do the right thing here? Should I return 410 for pages that are gone forever?
