Thanks for your reply Joe, very helpful.
now it's pointed out to me, it's obvious there's nothing pointing at the pages listed.
I'm wondering how these URLs are even being picked up though. Looking at the structure (/shop/article), they're possibly from an old version of our online shop... so mostly the products still exist, just not on those URLs. It might be worth putting a stack of 301 redirects in place of those 404s, or it might be a complete waste of time... II'm sure your blog post will help me decide. Thanks Again.
(edit)... yeah i reckon I'll 301 all those pages on which the products still exist... seems to make sense.
But I'd still like to understand where these URLs are being picked up... if they're not on our website and not found in In-Bound Links, where are they being found or generated???
