The first step you have to take is to register for a free account, and then write an introduction about yourself as your first post. The post has to be tagged with “introduceyourself” and should be reasonably long. It is an opportunity to list your social media and website links as well.
This was my first post two months ago on my birthday.
Steemit intro post
There are a lot of people upvoting first posts and mine got nearly $20, you can read it here.
The following posts I made got less rewards, less than $1 and it is the same for most people.
The key is to build more followers, especially followers that are participating in upvoting and commenting, and followers with more Steem Power.
Several of my latest posts got around $7 just by doing that and of course writing quality and more frequent posts.
