Just looking into my webmater tools and notice we have 112 listed items in feb when we were running VB5. Since the downgrade to VB4 we have none. How do i put these back in?
Unfortunate, Vb 4.x isn't well structured using schemas microdata markups, hence Google won't be able to pick it up automatically. It is one of the important SEO features though which makes it easy for crawling bots to understand your pages.
You can try to use the Data Highlighter to manually markup your pages' data but I tested it in the past and never liked it and it is not precise.
