How do you get on Google Define?

[Marshall_Motors]

I've noticed that when searching "define: _________ " there are times when Google will bring up a definition from a website. An example of this is when I searched "define: meta tag". Google brings up the definition given by searchenginewatch.com.

When searching "define: meta description" Google returns a definition from hubspot.com. I also searched "define: seo" and Google returned a result from Wikipedia.

So here's my questions:

1. How do I create a definition that appears in the SERPs? (is there code I should use for this? Does anybody know exactly how to do this?)

2. if I get a definition up, would the location effect the returned results? e.g. I put up a definition for "gobbledygook" on dansnasvhillebarbershop.com (of course located in Nashville). When Nashville locals search for the definition of "gobbledygook" will it pull the definition from dansnashvillebarbershop.com?

3. Do you have any places where I can read more about how it works and strategies to get definitions to come up in google?

Thanks!
