We work with an automotive industry platform provider and whenever a vehicle is removed from inventory, a 404 error is returned. Being that inventory moves so quickly, we have a host of 404 errors in search console. The fix that the platform provider proposed was to return a 422 status code vs a 404. I'm not familiar with how a 422 may impact our optimization efforts. Is this a good approach, since there is no scalable way to 301 redirect all of those dead inventory pages.

Greetings All... I've been digging through the search console on a few of my sites and I've been noticing quite a few structured data errors. Most of the errors are related to: hcard, hentry and hatom. Most of them are missing author & entry-title, while the other one is  missing: fn. I recently saw an article on SEL about Google's focus on spammy mark-up. The sites I use are built and managed by vendors, so I would have to impress upon them the impact of these errors and have them prioritize, then fix them. My question is whether or not this should be prioritized? Should I have them correct these errors sooner than later or can I take a phased approach? I haven't noticed any loss in traffic or anything like that, I'm more focused on what negative impact a "phased approach" could have. Any thoughts?

I have an automotive dealer as a client. The primary nav has a finance menu item, which (of course) points to the finance related pages. He just requested that I add a finance link item, as child menu items, under the new and used car nav items. Now, this is wrong for a host of reasons, what is the best way to communicate to this to him? I mean, I see this as a usability issue, it's wrong thematically, we would end up having 3 links pointing to the same page. Would this classify as dupe content?
