@KatieBabe16 Well, my best advice is to get in touch with the other members of the site. There really isn't any miracle way to do this, but there are plenty of guides on how to write on wattpad uploaded here.
As for getting more people to read your story, it's a combination of luck, hard work and patience. Add tags/keywords to your works and talk to other people, show them support and they will be likely to support you back.
Mingle in the clubs, (remember to read the guidelines which is pinned at the top of every club. Find people with similar interests, share your story in the club name 'Share Your Story' - and then just keep doing it (:
Hope this helped.
