I've once heard that if you promote your webcomic on their subreddit, they would do anything to spam bad scores to it until they pummel it to dust... so, promotion on the subreddit is out of questions.
so far I haven't heard anything too bad for the authors promoting there. I did promote a couple of times and gained some readers and no one review bombed me (yet)
Not meaning to be rude but duh, to get readers you have to expand your horizon to social media, ad space, stuff like that. The forum is more for discussion, and the only people who are really interested in that are creators/writers since they have similar goals, experience, passions, etc. It's only natural it isn't a good place to promote since creators are too busy making their own work to read other people's. (Unless it fits their preferences, but even then it's up in the air.) The Discord server is basically the same, but more people desperately trying to promote over eachother every second due to how the app works, so no one really gets seen unless you're already mega popular or really active.
The platform as a whole doesn't have anything to do with your readership problem, it doesn't matter where you post if you're not branching out with your advertising it won't get that many eyes on it. Sure, Webtoons caaan get you more subs, but it depends on your comic. There are many comics on there with less than 1k subs that just don't fit the demographic's preference. That being said, as Kelheor stated, why not post on both? Aside from my stand-alone site I post my comic on 5 other platforms (Tapas, Webtoons, Comicfury, The Duck Webcomics and FlowFo.) weekly/semi-weekly, and post in chapters/bulks on 2. (Dillyhub and Global Comix.) It doesn't take more than a few minutes to update them all. Just use both, it won't hurt anything.
At this point, I'll have to take in that advice, though I'm kind of new to the whole promoting on social media like Twitter and Reddit, don't want to just post a comment about my story on a random thread or anything, I also posted on Royal road but I do that weekly, the same for web novel, but besides that point, yeah I'm going to have to promote more to outside sources if I want my story to get more exposure, thanks for pointing that out.
I definitely get what you mean >.<; All the advice is go to places and promote, but that is what every other author is doing, so it's just full of authors.
I haven't been on the Tapas forums for too long, but I haven't really created a promotion post because I noticed that people were getting next to no likes on their posts in the promotion threads compared to a general post about anything. So it felt like everyone was just promoting rather then reading. At the end of the day, it's like looking for a webtoon to read, but you don't choose the genre or anything, so it's basically luck if you find something you'd want to read. So instead of promoting, I'm here to just to talk with other creators and learn tips.
Building up a follower base on social media can help alot I think. I mainly post my art on Twitter where I kinda have a small following. When a new chapter on my webtoon comes out, I post it a link to it and the views tend to jump up a good 20 or 30. I also have another webtoon which I don't promote on Twitter (on purpose, I'm experimenting!) and that isnt over 100 views after 7 weeks.
Even on Twitter, there's things called 'Art Shares' where you share your art with other artists. While it does help to get followers, I've kinda stopped doing them for the same reason why I'm not really doing promotion posts here. Instead, I'm trying to be more casual/natural, just replying to others and slowly building things up. I mean, after doing those 'Art Share' posts on Twitter for a year, I sent art of an apple I made to a popular post and doubled my followers overnight and I was like "Eh?". The followers I gained from that do interact with my work as well, and hopefully, see my webtoon!
This ended up being a bit longer then I thought it would be, hopefully it makes sense! 
No problem, thanks for not being upset, I wasn't sure how rude my response sounded. If it helps there are a few places you can advertise or get better feedback, and events you can do if you have the spare time. If you have some extra cash I've heard ComicAd Network2 is pretty good. There's also Webcomic Chat3 and Comic Artists Unite3, which are weekly Q&A's related to you and your comic that can give you some advertisement. There's The Webcomic Library2 which is a webcomic archive (The link to fill out a form for your comic is in the pinned tweet.) that also has a Discord server has Q&A events and weekly stream hang-out. You can advertise here, and more people would be open to check out your comic, but most of them are also creators. The server is more ideal for talking comics, getting advice and all that jazz.
Similar to The Webcomic Library, there is also the Webcomics Garden, another place that holds Q&A's, and is a good place to talk comics. They also have a Week-long comic feature for members who are active enough to get to a certain level, where everyone in the server talks about your comic for a week. For more professional stuff there's the Association of Comic Creators2 a server dedicated to discussion the more serious comic stuff, and a really good resource to have if you want to really start getting into the industry. The server has publishers, shop owners and all kinds of folks talking comics, and they're all very nice helpful people.
Lastly if you just want to learn more about comic, or hear about other people's perspectives and experiences there is Screen Tones1, a webcomic podcast hosted by enthusiastic creators who just want to scream about webcomics.
There's a lot more stuff out there, just keep your eyes peeled and keep up with webcomic community because you never know when someone will bring up useful advertising/comic related info. Good luck with getting your work out there!
Thanks a bunch, this is some really good information, but my question is do they also have anything for novel writers as well? Similar to the sites you just mentioned?
To gain more readers there are different things
Mirror your content, post your series in many sites/apps as possible, check out where you can post your webcomics or novels. If you can translate it to other languages, Webtoon and Tapas aren't the only platforms out there.
Promoting on several platforms such as Discord Servers, Facebook groups, SubReddits, Twitter, Instagram, Forums, etc.
Something I see is that (Especially writers) authors, instead of building a proper posting schedule to allow new readers to adapt to the content, to make the algorithm have a steady flow; they just dump their entire series expecting people will get interested like that, when the reality is no. Another thing that annoys readers or even other creators who are subscribed to other's stories and especially on Tapas is notifications of authors constantly editing the chapters several times and well, not knowing when exactly does an author updates.
Fanbases aren't build in thin air just because you've been posting your series for a few months, no, it takes years even more than 1 or 2, and several authors originally start with less popular, even shorter, series, some even change accounts so much that followers cannot keep track of then, as well, the most important thing is to make things accesible for readers, you're asking way too much even if you believe it's not, most of people only care about scrolling and see the next post of the content they see, so you either have to make extremely catchy stuff so they click the link to your series or chapter or be more creative with promo art, chapter previews and such.
Sadly, for most of authors that are not popular, what I've seen that boost their flow is for them to become content creators, not just mere writers or artists. Basically overwork yourself with challenges, art studies, tutorials, art classes, fanarts, tips, vlogs, streaming, speedpaintings, original art, fancomics, NSFW, memes, animations, promotional art, reading sessions (Of other people's content), constant engagement with other people be it fellow creators, those who aspire to be creators or just readers. And all of the above on different formats for several platforms, be it TikTok, Youtube, Twitch, Twitter, Instagram, etc.
Nice to see that someone else has thought this. I've wondered if Tapas isn't really a home for writers instead of a mecca for readers, so that there are far more writers on Tapas than there are readers.
Most forums on writing sites like these tend to be geared toward creators than readers. Something I've noticed about Tapas in particular is that unlike the other forums I've been on, there's no recommendation section, which I feel like eliminates the few readers who would've participated on the forums. It makes the promotion sections in particular feel like a rat race in a hamster wheel.
I've been meaning to ask, can you get to the forums from the main site? I've only been able to get here via Googling.
If you click the arrow button under tapas merch shop, keep clicking until you find tapas forums! Hope this helped.
Unfortunately no, I've never worked with novels so I haven't gathered any resources for writers specifically, and whatever I know if kinda died after the pandemic hit. Sorry about that!
@bulgariansumo I'm not sure about the app, but they still have a link at the bottom of the desktop landing page. If I remember right I think they had one at the top in a dropdown before getting a Discord server, since then they've limited it to the one link... that probably no one will see.
Is that for the mobile phone version or desktop? I don't see an arrow under tapas merch shop on desktop. There's an arrow on the discover tab, but none of the options show the forum.
@UrMom Oh, thank you! I see it at the bottom of the landing page. Wow, they really moved it out of the way, huh?
It's on the desktop version, check to the right were your series name/ edit series buttons are! I hope you find it, you should be able to see it.
Right? I think they were planning on getting rid of the forum all together, but it's been sticking around. Probably too many people who still use it, I know some folks prefer the pacing of the forum over the server. Myself included, I type and read too slowly for Discord.
@MalonTheArtist Ahhh, thank you. I see it now!
@UrMom In that case, I'm honestly surprised it's still up considering how Wattpad shut down the forums out of the blue. I'm thankful though. A high-traffic Discord server is a good place to get talked over, not to mention you can't sort topics like you can here. I'd get overwhelmed. 
Your welcome @bulgariansumo I'm glad you found it
