Is there a point to disavowing dead links with a 404 error? To be more specific, in Google web master, under "Search Traffic" and then "Internal Links", it's entirely made up of 100% dead links, with more dead links linking to those links. Should these all be disavowed or does it not make a difference? We don't have an internal linking structure in place either, so we have no idea how this is showing up in the webmaster. However, we could be incorrect in interpreting this data, so if anyone has an alternative point of view, it would be greatly appreciated.
