I think about this a lot, because it’s important to know what a realistic goal to expect from an audience is, even though I admit it definitely is kind of depressing when you look at the numbers. I was doing reading on what sort of money you can expect to make from a successful webcomic, and the general rule of thumb seems to be that if your merchandising is meshing well with your audience, about 1% will give you merch. I imagine ‘subscribe to patreon’ also falls in this general range.
Stuff that is ONLY available for dollars are obviously going to have a different way of measuring this, but when it comes to ‘If people can consume something without engaging back in any fashion (hitting a like button, buying something, leaving a comment)’ the vast majority will.
And as a creator that is frustrating but as a consumer it’s pretty easy to see how it happens. I have gotten steadily worse at even liking posts, much less leaving comments on ones I enjoy, since I started using tumblr. It’s very difficult to engage consistently. I always kudo on any fanfic I read and comment on the vast majority, but then again I don’t read a lot of fanfic, if you are someone who browses AO3 constantly/regularly for months or years, I could see how it’s easy to stop engaging. I don’t remember to like every YT video or tumblr fanart I see, much less comment on them.
When we are constantly consuming free content it’s hard to remember to engage with it or what that engagement means to the creators. And lol, honestly that sucks. Certainly as consumers we should be better about it. But also like, as a creator be kinder to yourself by setting a realistic bar of what you can achieve.
And IMO, if numbers matter to you (kudos, comments, etc) be honest about the fact that you CAN improve those things by marketing yourself better. The ‘I just produced my art and put it out there and got insanely popular because it was just so brilliant’ is less than a one a million chance. Lots of amazing content is overlooked every day because there is a lot of good content and a metric fuckton of mediocre to bad content. You can only SORT of judge the quality of your work based on the audience it generates, but if what you WANT is an audience there is way, way, WAY more you can be doing than simply producing whatever you immediately feel like. Marketing yourself is a skill and if you want the benefits of it you have to practice it.
