I would agree with Joanne that I was fortunate to have started back when there was less competition, thus easier to gain subs. Plus, back then the front page was much more friendly to new or random comics rather than constantly promoting the same premium stuff or the same popular series.
However, starting in 2016 or so, I did not struggle to reach and pass 300 subs in the first 2-3 months. Please note that my first comic series on Tapas was NOT BL. It was a comedy series that parodied all the cliches in manga. I drew my entire short series and completed before deciding to upload it at a rate of one page per day. The daily updates were very helpful for visibility, as I constantly got on the "New and Updated" list. Another thing I might note is that my artstyle is the popular "simple anime" style that many readers like. I did not start drawing comics until I felt my level of artwork was ready to handle so many poses, backgrounds, and angles.
Afterwards, I was sitting at about 700 subs.
My habit of uploading episodes ended up being "upload every day for a week, then take two weeks to one month off". Part of it was because uploading daily was good for visibility, and the other part was that I tended to gain subs slowly even if I didn't update for a while, so having an off month to replenish my queue while letting subs pile up worked for me.
Then I drew a sol because a friend of mine did, so I wanted to match her. That gained me another 200 subs or so.
Then my BL game started because I just wanted to draw a BL. I read so much BL, I might as well write one too. I just wanted a bare-bones basic BL with porn as its end goal. Boom. 3000 subs just on that comic alone.
Finally, I felt like drawing a family-friendly (ish) furry comic since most of the furry comics I read are hardcore porn comics. Maybe it was an original idea? Maybe not. However, that comic got onto the Daily Snack when I released the first episode. I gained a 1000 sub boost from releasing a single episode of a fresh new series just based on the concept, so maybe think about your series concept as well. Mine was fairly simple Phantom Thief VS Detective thing with just a slight kick that the characters were anthropomorphised animals.
I currently have 6000-something subscribers from a mix of all my series. I'm semi-active as a hobbyist creator, so perhaps my subs deserve better than someone who updates when they feel like it.
