for now, I believe on the STEEMIT homepage, on the right hand side you have a list of categories/hash tags. They are both I believe. The top one I believe are most likely the most popular so try to use "steemit" and then others based on your topic. Try to use the appropriate tags and yet the most popular. It helps, but will most likely help more when there many more users. It is still early here on STEEMIT.
GOOD LUCK and more importantly, enjoy and have fun with what you are doing.
