Welcome to the Q&A Forum

Hello, I have a large number of product pages on my site that are relatively short-lived: probably in the region of a million+ pages that are created and then removed within a 24 hour period. Previously these pages were being indexed by Google and did receive landings, but in recent times I've been applying a NoIndex tag to them. I've been doing that as a way of managing our crawl budget but also because the 410 pages that we serve when one of these product pages is gone are quite weak and deliver a relatively poor user experience. We're working to address the quality of those 410 pages but my question is should I be no-indexing these product pages in the first place? Any thoughts or comments would be welcome. Thanks.
