Should I use Microdata markup on my blog or should I put just an JSON-LD with all info, or is using both the best option?
A bit of explanation. I am trying to mark up my blog and I manage to get to 1 error left in "Structured Data Testing Tool". The error left is a publisher meta. Now I don't want to add blog info at the bottom of the post. I used Organization meta in header where my logo is, but testing tool doesn't take it into account.
Should I add JSON-LD duplicating all info and adding publisher data or should I use just JSON-LD and not bother with marking whole page?
