1) Promote. Mostly off site. Try deviantart, reddit, YouTube, Instagram, etc.
2) Engage. Like, comment, subscribe to other works. Join contests, fanart exchange, etc.
3) Have an engaging plot. First page, chapter, etc. Must have the "hooks" in already. Something like a fight, argument, or anything the media can use to sensationalize the news. Riots, shooting, police, protests, etc. Cliffhangers are also good to use.
4) panel dialogue... since you're competing with ever decreasing attention span, don't put too many words in a speech baloon.
5) phone scroll format > traditional comic format (I know some of you will disagree here. I just find phone scroll format easier to follow. )
6) Art quality must be decent enough. A good benchmark for your art ability is if you've been FALSELY ACCUSED of AI use at least once.
7) Your characters have to be good looking. I'm aware of people reading your comic just because they think the ML or FL is good looking.
Just my 2 cents on the matter...
