Tip #1: Link your series or Tapas page in your forum profile description! Otherwise when I click your name, I have no idea how to find your series (except to go through your forum posts and hope you've mentioned it there lol) There's no way to search for comics or novels by title on here, so just saying the name of it won't help if we don't have a link. And if you need to hyperlink on the forums, there's a little icon next to the " symbol that says 'Hyperlink' when you hover over it. Just highlight what you want to link and put the address in the "Insert Hyperlink" box.
Tip #2: Try engaging others. You can do 'Review for Review' threads on the forums, or just self-promotion threads. You can have contests once you get a bigger fanbase and doing collabs with other creators can be helpful too. Just interacting with other content/creators increases your chances of getting your series seen.
Tip #3: Social media is always a good one. Places like Tumblr, Twitter, Instagram, and DeviantART are some common choices.
