I'd add that you need to do a few other things:
-make sure what you're posting is high quality and original. Because you're actually assessed on your value add and it's public knowledge, it's worth it to make sure you're not just "robot-ing" the system.
-know that posting isn't everything. You need to interact through comments, upvotes, and shares and constantly ask, "How do I add value to Steemit?"
-I'd also recommend adding a video to every post you make.
-Finally, I think it's probably worth adding a few links to other posts you like at the bottom of your post. That makes it easier for your readers to continue to find the value that you add.
