Residential
Ads,affiliate and ECOM, if you can collect emails also
Dunno, I am not tracking it, but I would guess somewhere around 300$-500$ per month, because I have few ECOM sites with incredible margins, and also I am promoting high CPA offers and all my sites are having some kind of ads on it as well.. but I am not tracking it, but one of the stores was completely dead with 0 orders and now since I am promoting it on Pinterest, I get some sales again .
Btw: after I get back from vacation, I will try to get to mediavine, since I have talked to people who got their sites in with less than 10k traffic per month.
