Personally speaking, you don't necessarily have to promote yourself on every single Promotion thread in the forum, to be honest, the majority of users here are annoyed by said Category and many don't even check what other people post, is spamming at this point.
Most ways to actually get people from here to read your series, is by having the self-promotion be in a third plane while the main focus is other thing, be it providing advice, sharing your process, resources that you have and such.
Promoting in social media is not really that hard nor tiring, especially if you use those apps or websites that allows you to post in three places at the same time with just one click. Regardless if you post a link to your hosting platform or make a social media version of your chapter for others to read.
For example, by using Buffer you can make a single Post that will be posted in three different social media, let's say IG, TW and FB.
You could do two things:
- Make a Social Media format of your comic to share as a post in these websites/apps
- Preview/Thumbnail of the chapter, lil' description then link to where to read.
However, I've noticed that redirecting people is harder than actually providing the chapter there for them to read:
When you use a social media platform, you expect to see the content there, not be redirected to a different place where you have to make an account, verify said account, click again on your series because the page was lost by creating an account or logging in (Yeah, happens some sites redirect you to a dashboard or main page instead of the comic/novel you are trying to read), then having to subscribe even if it's once, then commenting or liking becomes an even more tiresome task or the person may have lost enough interest to even bother on doing that.
So, a Twitter user would likely prefer to read your comic through there since its easier for them to retweet, comment or like. Everyone likes few steps and easy access to stuff with minimum or no effort whatsoever, imagine you're always dealing with toddlers with a very short attention spawn
