Oh, this is a neat thread I'm also interested in seeing what kind of average view/sub ratio there is, so I'll contribute my data to the cause ^^ ~
My first comic (ongoing, gag/episodic): https://tapas.io/series/Proto-Comic
Views - 4507
Subs - 50
View/Sub - 90:1
Rating: I've always thought this would be below average due to my mostly low-quality art (especially in the beginning), since I'm sure it doesn't give a good first impression for viewers.
A series where I post random art: https://tapas.io/series/Toads-Misc-Art
Views - 986
Subs - 19
View/Sub - 52:1
Rating: Good, I guess? I mean, considering it's not even a comic.
Completed one-shot - https://tapas.io/series/The-End
Views - 734 (series page) - 835 (dashboard)
Subs - 132
View/Sub - 5.6:1 - 6.3:1
Rating: Holy mama what
I've noticed what @Rhonder mentioned also - the total views in the dashboard seem to add up to a different number than the one shown on the series. Since the one-shot was posted all as one episode it was convenient to get both numbers, but for the other two I just used the number on the series page.
I also really don't understand the last one, I hope everyone who subscribed realizes it's finished and will probably never update again XD. Or maybe it feels like there's no cost to subscribing to a completed series since you won't be bothered by updates you may not want to read?
