I'm working on a side project with a user base that is pretty vocal about their disdain for ads (see: Reddit), and since this product is B2C, I've decided not to charge a subscription fee.
Instead, I'm considering going with a donation model. Has anyone had successes or failures with this, and if so, care to share those metrics?
One of my business partners tried this a few years back.
You will have to battle "donation blindness". If they see it regularly, they will tune it out. I told him to try two approaches (his was a free SaaS web based product, so adapt to your scenario):
1. Change how you're asking for donation (in his case, he switched it from bottom to the top of the product, and added an ugly handwritten note). Change the whole pitch once in a while. Remember, you are begging. You need to catch their attention.
Being funny works. Being anti-corporation works.
Did you get a C&D from a big corporation? Make sure to let them know. They will help you in anyway, as long as you're standing up for the little guy.
2. Once in a while, usually when you get desperate, try an intense donation campaign ("My servers are about to be shut down because of traffic spike and I need your help - will you help me?").
For him, the second approach with a specific amount mentioned ("need to raise $xx,xxx urgently to avoid _____") worked better.
General thought (for this demographics): More text, less graphics. Ugly works.
Final note: Be honest, as much as you can. It pays, in the long run.
YMMV. Ping me if you need any more information.
