I'm about to delete 40+ pages that have quality link juice (I'm deleting them for copy write issues). I'd prefer not to do a 404 header on all of them, because I want to preserve inbound links to those pages for SEO. Can I do a 301 redirect to the homepage for all of the deleted pages? I'm concerned because the homepage isn't similar content (It states that a 301 redirect should only be done if the page being redirected to is similar content).
If 301 redirects for the deleted pages is the wrong approach, then what should I do?
