A website I am working on need to clean up their site. Their site has over 300,000 pages as it's an e-commerce site.
I have suggested them to do the 301 redirects for the product page that are discontinued or permanently removed, which this case is ok.
But what about the temporary out of stock page which should be returning active in a couple months (or longer)?
They actually have lots of temporary out of stock pages (over 50,000 pages) which now they don't have link anywhere on site to those pages, another meaning, they are orphan page at the moment.
At first I was about to suggest to 301 redirect to their product category page (depends on which product falls into which category).
But I am afraid that 301 will cause Google to remove those temporary out of stock pages from their search result and not sure if I remove 301, those pages will get back into Google again.
So what is the best practice for those pages for the time being?
Many thanks in advance
