How To Index Citations?

In episode 115 of Semantic Mastery’s weekly Hump Day Hangouts, one viewer asked how to index citation sites in Google.

The exact question was:

Hey guys hope you’re all starting the year off with a bang! I’m excited about this year and believe I will be able to finally join the Mastermind so looking forward to that!

My question is, How are you indexing your citations? I still have quite a few not indexed and they were built a while ago now. If I just copy and paste the url of the citation page into google and it doesnt show does that mean its not indexed or may my links still be indexed? Cheers
