I’ve made money from selling words over the web. Not necessarily from words on the web…
Years ago, I used to write tutorials for Dreamweaver sites (yes, it was that long ago). People would rather pay $2 for a tutorial they knew was good than spend time looking for something not quite right. You pitched the paid content at just about how much a person might value an hour or sos lost income from Googling. I used to make about $100 for the writing then royalties, if I remember rightly. Haven’t done this in years though, so not sure if the model still holds.
Lots of places sell eBooks in one form or another. If your content is well thought of, you can make money selling ebooks at $10-20 a pop. I do this currently for my RPG writing over at RPGNow. There’s similar things with Amazon, Apple, Lulu and others. I know several people who make a side income from this, but it isn’t quit your job levels.
The hip kids are all creating Kickstarters, of course. To fund their content creation and give you unique bonus doohickies too. This can work well for eBooks, comics, real books etc. I’ve seen it work for website content. They thrive on the “I have a special relationship with the content creator” vibe.
The even hipper kids are using Patreon, which is micro-patronage. You promise to pay some small amount whenever a creator makes something cool. You get early access to that cool stuff, maybe some special bonuses. It’s basically a more distilled and ongoing take on what Kickstarter do. I back my friend Epidiah’s Swords & Sorcery zine, and several others. Its transparent though, so you can see how much my friend gets every time he delivers an issue. Browse around and you can get a feel for different people’s success with it on different content.
So yeah, there’s a few ways to make money from content (I mostly know words, I hear PledgeMusic is good for music etc).
