Do you have any personal experience or any other sources that estimate this kind of thing? I'm legitimately curious, I've often wondered what kind of revenue these types of things pull in. Obviously if they're not running ads and don't have any explicit monetization then it would be very little. But I always wonder about the ones that do.
Simply running ads doesn't really seem like an issue as long as you're not making the site unusable. I'd be more concerned about the fact that the average user in need of a base64 converter is arguably more likely to be using an adblocker.
Would it? Like, Google isn’t going to boot you for running AdSense on your site.
I’m guessing the money is made off search engine visitors rather than recurring visitors that would figure out how to do it by command line.
also, how would a search engine visit make money?
