I am discovering Google Search Console, and I have found that my blog seems to have many errors on Google's Structured Data register (microformats.org):
When I make any live test in one of this pages, the Google Structure Data Testing Tool shows no errors and no warnings at all.
All of the pages are "Last detected" on 10/4/7
Is this because Google has an old register about my pages? They did have microdata errors on the past but are now corrected. If this would be the reason, how could I ask bots to check for this again, in order to update results?
