I've been using project wonderful for a few months now. To be honest, I'm still not sure about it. For a while I had a lot of interest, but it seems to have slowed down. I've tried different ad types and different price points, but they haven't seemed to work long term. I'm not sure what the magic sauce it to make it a continuous money maker. I'm going to keep trying to figure it out, maybe switch it up a little more.
Until I successfully figure it out, I may try to explore other opportunities of accepting sponsorships. There are so many possibilities out there it's hard to decide which direction to choose. To those of you who have done both, what has your experience been? Share your war stories here, we want to hear them!
