I'm not the web master at work, but I'm the content manager (and complete SEO novice) with a question we're unsure about. When a product is no longer current and no longer carried in our store, we set it to "information only: item no longer available." The original idea was that these pages might be necessary for customers with older products that needed info. We also didn't want any links that might be out there to be broken.
The problem is that many of these pages are horrible from years ago when they had nobody doing content--copy and pasted descriptions, no meta description, etc., and they're throwing HTML errors in Webmaster Tools.
I don't want to spend time fixing the Webmaster Tools errors on old pages, but is it harmful for us to leave these pages on the site? Or is it more harmful to delete those pages and possibly leave broken links out there where a user would get a 404?
We use Magento Enterprise if that is pertinent. Thank you in advance!
