First, you should read a few steemit blog posts about the upcoming hardfork 20 that is scheduled to occur Sept. 25. Next, familiarize yourself with some of the sites that use the steem blockchain such as d.tube and hede.io.
You should also join steemfollower. You can use my referral link https://old.steemfollower.com/?r=17107 or simply use https://old.steemfollower.com/. In either case it's a good website to join. You can curate steemit content there and other members can find your content and curate it.
Finally, don't be afraid to use bots to promote your work. My personal favorites are @minnowbooster and @buildawhale. Both of those bots have a good reputation and integrity.
Good luck.
