Welcome to the Q&A Forum

Hi Graeme, For old product pages - your solution is good regarding showing users alternatives to the out of stock products. No need for an "out of stock page" as there's no value in that for crawlers or users. Regarding point 2 - if you redirect discontinued product pages to category pages that should be fine although Google may regard that as a soft 404. If there are loads of products like this and you 301 them in one go then the chances are it will flag up in Google WMT. If there are a small number and you introduce them gradually then you'll probably be fine. For the crawl errors question, adding value to the pages in terms of related products is a good solution if that's viable and the pages will be different enough from each other (i.e. no duplicate content). One thing that isn't clear at the moment is if you're redirecting empty category pages all to the homepage - or if it's possible to redirect or canonical them to their parent category. e.g. For home -> clothing -> men's clothing -> shoes If all the men's shoes are discontinued, then redirect that page to men's clothing rather than to the homepage. This reduces your chances of getting a soft 404, and is also arguably a better user experience. Hope that helps, George
