Steemit posts are indexed by Google so someone could be searching for information on starting a YouTube channel and trip across a Steemit post from 4 months prior and end up getting an Amazon Merch shirt!
Actually, the structured data markup is not that great on steemit. I've opened a proposal for that and I'm working on a fix that I'll submit as a pull request at the end of this weekend. I'd be happy to get some feedback or suggestions in the comments of the post. Let's make steemit outrank Medium in searches!
