I tried FB, Instagram, Twitter over the years. Like maybe 10 people a month combined.
Found Comic Fury, been on it for 5 years it blew up for me over night. My uncensored 14+ (CAN rated / 17+ in US)
Tapas and Webtoons, I have to rate in US strict ratings to PG13, so I use it as a funnel for people to notice my uncensored version on Comic Fury and it does work. I use written text within my pages for that notice. Webtoon....so many problems with bots, flagging my pages for things that do no exist. I find Tapas is more romance. I do more horror / fantasy / action.
Kami is better for webtoons not manga format. Even if the site allows reformatting for viewership for mobile and desktop.
On BlueSky now, I made an account for my manga. And that gets alot of engagment.
I joined a few feeds on there looking for comic fury, webtoons and indie manga. And I can see daily content from other creators quickly. I added myself to those and lists and people find me better with the tags I use.
