One way that people monetize their blogs or websites is by using a donation button. You might have seen them. Typically they’ll say something like, “If you read this blog help support us by making a donation.” It’s not that different from what PBS or NPR does.
I don’t know about you, but I’ve never made a donation. The exception is sites that offer free software or WordPress plugins. If I use someones code and it saves me time then I think it’s only fair that I make a donation.
ProBlogger was curious about this issue and has an article about the effectiveness of the donation button. For an interesting look at the topic read their article, Should I Add a Dontion button to My Blog?
