Welcome to Tapas!
General novel-posting tips:
Shorter, more frequent updates are encouraged: The majority of Tapas' userbase read on phones or mobile devices via the app, so shorter episodes are more friendly for that. But because you may be chopping your manuscript chapter up into more parts, it means you'll appear in the Fresh section more often!
The Fresh Section: This section shows series that have updated. But keep in mind, you appear there only once a day! So it's best not to publish an episode more than once a day, an important tip if you've got lots of backlog to upload. Space updates out on a regular basis, consistent uploads is important to gaining an audience here on Tapas.
How to grow your audience here on Tapas: Along with updating regularly on the main site, engage with your audience when they comment, thank them in the episode description when you hit milestones, or be engaged in the works of other creators. As for straight up promotion, these forums are a great place to start. Promote your work in appropriate threads, but the ones that get the most engagement usually have you share a bit more about your story, like talking about your characters or genre specifically. Also, don't forget to put a link to your profile/series in your forum profile! Here your username can be clicked and an info window pops up: you wanna make sure your work can be found easily! Finally, don't forget to promo your work on social media too!
Hope you enjoy your time here!
