I had an old catalog with way more products than I have now. I deleted the products, however, google still sees the empty product pages and says they are orphan pages since there are no links to them. I do not want to add links since the products are no longer available and the pages are basically an empty product page shell.
any advice on how to eliminate these orphan page errors? I was thinking about 404 or 410 erroring them but wasn’t sure how to go about that either.
