I used to post on Wattpad, long before it got bought by Webtoon. Back then, the site was easier for me to navigate and find all sorts of story genres, including new writers.
But now, in my personal experience, if you post there, yours might not get seen via algorithm since they heavily promote/prioritize the premium Wattpad authors' works there, their promoted roster of specific genres, & umm...lots and LOTS of ads (even when I'm just trying to read a non-premium story). That was just my personal experience after trying to post again on Wattpad last year, from what I remember. So, I just stopped using/going on Wattpad.
Still, I haven't checked out Wattpad this year so far, so maybe things have improved at least a bit since then.
