The traffic required to get to $100.00 per day with Adsense would depend on the niche your website is in.
A high paying Adsense niche may only need 3,000 daily unique visitors or 90,000 monthly visitors to reach $100.00 per day.
And other low paying Adsense niches may need 10,000 or more daily unique visitors to reach $100.00 per day.
10,000 daily visitors would be 300,000 monthly visitors.
