What the H is Microdata?

Not a question I ever would have thought I'd ask.

Well, I'm on a forum at a revenue-sharing site on which I write, and someone is talking about micro-data. Yes, I know. I should have Googled it. But instead I use my own brain and somehow am able to decipher the term and figure it means there's code underneath elements on a web page. So, I inquire a bit more about that on the forum. Someone chastises me a little by telling me this evidently obvious fact was already stated, that micro-data is code in page elements or features.

Let me tell you. I've practiced Karate since the 80s, taught it since the 90s, and I would never dream of teaching it by throwing out terms without explaining what they mean. Go figure.

Anyway, I'm still learning the technical stuff about writing online, I've been writing online for about 9 months; as long as you don't count micro-blogging. I've learned that SEO is Search Engine Optimization and that SERP is Search Engine Results Page; I've learned the Google search engine has crawlers that might or might not crawl things on your page and might or might not index your page.

And I've found how important all this is: You want people to see your stuff, you got to know about or have tools for SEO. And micro-data is important.

Okay. I'm done.
