I actually think that posting every day sort of hurts your speed of growth. I'll explain:
On Monday, I post an update. 50% of my 100 followers happen to read the update on Monday, and 50% of those followers like and/or comment/share. That means I got engagement with 25 people and the Tapastic site registers that for how it ranks my comic in popular/trending.
On Tuesday, I post another update. 50% of my followers happen to read the update on Tuesday, but maybe only 45% engage (engagement fatigue is a thing). Some of those followers hadn't read Monday's update yet, though, and even when they catch up -- they tend to only engage with the latest page.
On Wednesday, I post another update. This time I might only see 40% engagement of the followers who read the comic.
Over the course of weeks, a month, many followers stop reading the updates every day. Maybe they read once a week to catch up, and then comment/like/engage with whatever the newest page is at the time that they DO read. The problem with this is that now I have given up control over when my followers engage with my comic. And that means that the popularity algorithms that are best positioned to help new readers find my comic aren't ever reaching the level of visibility that they would, if say ...
I just posted 1-2 updates a week and spread their timing out enough so that every time a page releases, my followers mostly engage with it within the period of a couple of days. That seems to be what the popularity algorithms prefer -- focused engagement within 1-2 days after an update.
Anyways, that's how things tend to work based on my observation of different new comics and my own comics. For a daily funny strip or some such, or a book that has enough popularity that even lower % of engagement triggers it to be popular/trending, more frequent updates might work better.
So, TL;DR -- save those extra chapters! Release slowly and be okay with Tapastic taking time to catch up to your comic. That's the best, most effective way to grow an audience here.
