subbed to your work. art looks good, I'm well above 20 subs, and I'd say I'm good enough to give advice. What you need to make sure to do is to keep posting in new threads, sometimes on the daily.
If there are no new threads that you can use, make your own like this. Its also important to be relatively consistent with releases. Don't spam threads though, this site frowns upon that, and they get annoying, since everyone's on the hunt for new threads to post in, and if its the same person every time, people are gonna get annoyed(or at least I do)
I come out with a new chapter about every Saturday with some exceptions.
Don't expect much money from releases, instead its a good idea to build up an audience before making a Patreon of some sort.
You prolly shouldn't abandon Tapas after that though, as its a good way to build your audience. It would be best to find other ways to get people to the patreon, like making sure its ahead in terms of releases.
Next, its good to schedule Tapas chapters, that way you can keep the audience in the know.
share posts with subscribers often, updating on progress in some way, also make sure to click the bell icon before making the post so the audience sees it. Doing this will keep your series in the reader's view.
Though if you go back to update a chapter, but make sure its not too much. Its not a good idea to have people constantly going back to chapters to see what slight thing has changed. If you make a small edit, don't notify them on it, maybe just make a quick post about the change, that way you don't risk wasting their time. For as much as they love your work, if you keep notifying them about minor changes to pre existing chapters, that would get annoying.
You don't want to make major changes either, because that risks turning the work into homework, which would not be fun.
