Pretty much right from the word go. It probably helped that it's fantasy, isekai, smut, all the popular tags. I uploaded ...I want to say ten chapters immediately, kept a consistent schedule for something like half a year of first two and then three chapters a week, and had a serviceable cover image. Admittedly, my synopsis was kind of rough (I'm still not sure how to write a good synopsis, but it's at least better than it was). And importantly, I already had a readerbase on CHYOA, at least a few of which popped over here and gave me an immediate boost, if a small one.
I'm not super popular, but I have a loyal readerbase, and at least a few of them will comment pretty much every chapter. I haven't specifically checked, but I estimate that I normally get about five hundred pageviews within a couple days of uploading a new chapter, and that's with a sporadic upload schedule. My latest chapters have pageviews ranging from seven hundred and fifty to around a thousand, and my earlier chapters are up to two or three thousand. Favorites are much lower, with most of my later chapters having between twenty and thirty, and the earlier ones having just under a hundred.
Note that when I say pageviews, I mean views on one chapter in specific, not on the story as a whole. That stat doesn't mean much of anything.
