I'm always curious how many visitors you have to get to reach $500 per month numbers from ads. I understand the author probably can't reveal exact numbers here but if anyone knows rough but real life numbers I'd be curious to hear (I haven't ever done ad based revenue myself and I don't trust CPM numbers I'd read by googling, or the spread is just too broad).
Just to compare, https://nodemailer.com had 194k pageviews (42k “active users” as reported by Google Analytics, whatever that means) in January and the BuySellAds payout was $156.45
Thanks for putting some numbers out there.
