Here's an estimate, rough and from small-N sample size:

Quoting:

"Looks like 26 people donated 50.35BAT in 25 days. comScore has 100 page/day browsing average. Assume 1<=N<100 http://aternos.com pages per day for all 26 ppl & all unblock ads there: at most .65N x PageCPM <> 50.35 BAT or PageCPM <> 77.46BAT / N =~ $20/N. I believe BAT wins."

Again, disclaimers: rough, small-N, lots of other problems. We will do proper case studies as we can. But assuming we would max out at $300 to you is unjustified.

Thanks for that, Brendan. More data is always helpful, even when small-N like this. We're going to continue participating and monitoring it for PortableApps.com and see how things shake out. Also, the login page caching and editor issues seem resolved over the last few months so I updated my post in our forums.

The median donation to Wiki is, of course, $0. By giving anything users would be giving infinitely more than the regular user.

It'd be quite interesting to know what your aggregate CPM is. One way you could probably determine brave users is by contrasting raw user agents against your analytics data. The discrepancy there is going to be some mixture of Brave and those running other things that also block analytics like uBlock. But it should at least you give you a very rough ballpark CPM that's probably going to be much more reliable than e.g. a survey.

One other important figure that Brave could probably roughly answer (but also probably won't) would be what percent of Brave users opt in ads.

We do share numbers, working to get up from the 40% opt-in we had on desktop now that we've got ads on Android (iOS to-do). The opt-in is mid-teens right now, I think -- we will drive it up cleanly via telling users about it and rewarding them for joining.
