I've seen a couple of mentions about this. How does that work exactly to get them removed?
I've got a large number of pages I removed with their removal tool about 5 1/2 months ago after rearranging my site. So, I'm expecting them to reappear soon. I have a 410 redirect in place and was expecting that would sort them out when they reappear. However, I never see this method recommended as a solution to solve this problem.
Could someone comment on if the 410 redirect will permanently remove these pages, and if not, why not. And then explain how putting up a replacement page which can be indexed solves the problem? What to do after they've been reindexed, for example? Is a "Hello World" page all that is required for the indexable page, or what?
