On: Ask HN: Ad supported website. What traffic is required to sustain it?

[kitcar]

back of napkin, $2 CPM, CPM = 1000 banner impressions. 3 Banners per page, mean $6 Page CPM. $3000 / $6 = 500, therefore you will need to generate 500,000 page impressions per month. 3 page impressions per visitor means ~166,666 visitors per month

Lots of assumptions made, but gives you somewhere to start.

Thanks very much. I understand its a rough method. I will try to refine it. Any sources that I can read from? There are many sources online, but they are not curated.

$2 CPM seems high these days, I'd assume $0.50 for a transactional website and $0.10 for a social one.

Even $0.50 is pretty high ask.
