Like @vvbg mentioned, it important we shift the thinking of web comic readers.
I challenge the idea that comics have to be fundamentally free. The good ones take just as much work, time, and effort as a novel or movie
The Premium comics and Incubator comics have, generally, more quality stories and art than comics made as a hobby.
Yes there are high quality comics that get support via Patreon if there is enough popular support for it, but I'm not going to focus on those for the purpose of this topic.
I don't like the term Paywall. It's like saying I want to see this movie but there's a paywall of buying a ticket.
Ideally I see this "paywall" as buying an ebook. Once it's bought (incrementally or not) you're free to read it however much you like. This applies to an innumerable number of books, why can't it apply to comics?
And its high time we the creators start telling our readership that. We can share our process and how long each step along the way takes. We can show in a behind-the-scenes everything created that didn't make it into the story but had to be made for the sake of the story.When people understand what it takes to make a story, we begin to bond and empathize with one another.
The thing is, it's the story that we're selling and that's the thing of value in a webcomic. Those who create these stories in the web comic medium as a living are no less professional than best selling novelists or movie makers.
It's a new and growing industry and so we face the task of getting readers to understand that supporting quality stories not only helps the creators make more stories but Tapas itself. And the bigger Tapas gets, the more opportunities they can give for creators who don't want to sell the digital comic itself but some other methods of earning from their work.
I don't think the model is bad on Tapas, considering how cheap the comics as a whole end up being. And if you make it clear as to what it is (premium/paid comic) then there are no surprises.
What's needed is a fundamental shift in how we treat creators of quality content. And the only way we can do that is through educating the readership that, yeah, if you want quality stories you have to treat the comic like you would other beloved entertainment.
There will always be those who will never want to pay, and that's fine. It's not in my locus of control.
I happily support the stories that I enjoy and $5-$20 really take you far. My Incubator Comic won't be published for a while but I have no qualms with the modest pricing because I know the story works, and those that enjoy it will have even fewer qualms about supporting that content. It not only helps me but the entire Tapas team and future creators. Don't we want this site to thrive?
On advertising/marketing: that's just placing the comic where people can see it.
All you have to do is go out and share it everywhere you can, as regularly as you can, and in an interesting manner. That last one is important. It answered the question of "why should I click on this link to your webcomic?"
Present the premise of the story concisely and if the story is good it will hook people in. It all comes back to first and foremost having a quality story to tell.
Movies and novels have no problem selling if they're good right? Web comics can be the same.
