Methodology
Our provider rankings rely on a rigorous, data-driven framework evaluating over 100 million rows of FCC data to bring transparency to local internet options. We track 8,000+ active plans from 2,000+ providers to cut through marketing jargon. We weigh technical factors against real-world experiences to match you with the best connections actually available at your address:
- Tested Technology: We utilize a fiber-first ranking system, prioritizing high-performance, structurally sound technologies (like fiber and cable) over slower legacy connections.
- Realistic Coverage: We filter out "ghost ISPs" with near-zero availability and actively flag providers that only cover a fraction of neighborhoods, ensuring you don't waste time on unavailable options.
- Transparent Pricing: We track base rates and downgrade providers that rely on hidden fees or sudden price hikes, exposing the true long-term cost beyond initial marketing promotions.
- Verified Speeds: We look beyond deceptive "up to" marketing claims to evaluate the actual download and upload speeds delivered, prioritizing the balanced, symmetrical performance necessary for seamless video calls and heavy streaming.
- User-Driven Personalization: We don't just look at the tech; we look at what people actually prefer. By analyzing millions of local connections, user reviews on downtime, and validated J.D. Power scores, we tailor our rankings to highlight the providers proven to satisfy users in your area.
