Methodology
We rated the largest internet providers in the U.S. for 2025. Each provider was rated on a scale of 1 to 5 based on over a dozen factors, including speed, cost, availability, fees, customer satisfaction, connection type and more. We also used data from the Federal Communications Commission (FCC) to compare the average speed offered by internet companies in the U.S. to set a baseline for what is considered a good internet speed. Additionally, we analyzed data from the American Customer Satisfaction Index (ACSI) to understand how each internet service provider (ISP) fares in customer service and perceived value.
