We are an eCommerce site with about 50,000 pages. We decided to focus on about 2,000 so google will crawl our site better. We planning to remove 48,000 pages from the sitemaps and from the site links, so it won't be accessible through the site. The pages will still be accessible if going them directly. Our concern is that these 'orphan pages' will damage our SEO. Are that many 'orphan pages' can harm our site? Redirection is not an option since we will use some of the pages in the future.
