I've launched my first voice app on Amazon Alexa, how can I promote it?

Hi everyone, I've just published my first voice app on the Amazon Alexa store and I'm waiting to get approved on Google Assistant.

Now that I've published it I see the first user coming and I would like to understand how could I promote my application in order to get more users.

Could you please share some common scenarios about this topic?
