Sure, I'll throw my hat in the ring. My current comic is The Shapeshifter's Wife, which has a slow build of ~320 on Tapas, but a ~4,200 on Webtoon. Which is a huuuge freakin difference and I'll dive into that:
Tip 1: So my first tip is to spread your comic onto different platforms. They have different demographics, hence my huge difference in stats.
Tip 2: Make sure your first 3 episodes have the heart and soul of why the hell you are making this comic at all. This includes your hook, of course, but those first 3 episodes should be very polished, and try to make them longer than your other ones (on WT I uploaded in JPG so I could fit all the panels), make sure it's your best foot forward.
Tip 3: Webcomics are weird because we are posting short spurts about once every 2 weeks. 50 comic updates look like nothing on a script, and would be a normal slow build for a graphic novel, but is actually about 1-2 years worth of posts where nothing happens, and a year for your readers to wait. So remember, you're making a webcomic, which is a very different medium, and you may need to skip straight to the Good Stuff that you're excited to draw. Don't wait to show you love interest, don't wait to show the fun sword fight, just get to the good stuff so your readers don't give up on you.
Tip 4: You get out of the community what you put into it. Doesn't really matter where you're posting, discord, reddit, tik tok, instagram, wherever. You cannot spam links in art shares and then run away and expect anything to come of it. You have to comment on other peoples content, on other people's social media posts, engage with other creators, and remember to be nice.
The staff who choose who gets promoted are on all of these social media channels, they see your posts, especially if you are chatting with their official posts. This is how they find you for promotion, and I know the reason why I've been promoted on Webtoon and on Tapas is because I paid attention to what they ask for when it comes to making phone friendly, app friendly content that matches their art expectations, and I have an active twitter and I show up in the discords and participate in community events when I can (long covid made me take a 4 month break but I'll get back to it soon hopefully)
This doesn't at all guarantee you'll be selected (I've seen wonderful comics that haven't been selected at all and it's been YEARS) but I don't think begging the staff to promote you, or being mean or self deprecating on socials, and ignoring the rules of the platform by posting content they literally can't promote will help you get promoted.
Tip 5: And for my last tip, it doesn't matter if you go viral anymore. Sub count isn't what matters the most, it's the engagement rate that matters. We live in the age of Tik Tok, where you can go viral easier than you could at any other point in internet history. Problem is, going viral from front page promotion or a really good video and getting subs doesn't mean that your subscribers will come back.
WT and Tapas both use engagement ratings to determine which series to green light or invite to the creator bonus programs. So sit back and do the math: how many of your subs are leaving comments, coming back every time you update, or liking your stuff? Subs alone may unlock ad revenue, but ad revenue is so little nowadays that I consider it a waste of time to solely focus on it.
Is there more you can do to get readers excited about your next update? Can you pace things better so they have to know what happens next? Are you leaving enough flash backs and summaries when things get complicated, so your return readers don't get so lost that they immediately unsub? Are you interacting with your community in the comments and online so they feel like they are welcome to leave comments? Try and make it a welcoming place they want to return to.
