The amount of traffic you need to make money from ads depends on the ad network you’re using and your niche. For basic ad networks like Google AdSense, you can start earning with as little as 10,000 visitors per month, but don’t expect significant income at this level. To start earning a livable income, you’ll likely need 50,000 to 100,000 monthly visitors. Premium ad networks like Mediavine and AdThrive require at least 50,000 and 100,000 sessions per month, respectively, but they pay much higher rates than Google AdSense. If you’re in a high-paying niche like finance or technology, you can earn more from fewer visitors because advertisers are willing to pay more for ad placements.
