Our Methodology

Our provider rankings for Granite City, Illinoisare built on verified coverage data pulled directly from the FCC Broadband Map — the federal government's official source for internet availability across the United States. We combine this with AI-assisted data analysis and publicly available provider information to build accurate, up-to-date plan comparisons. Our goal is simple: help you see exactly which providers serve your address, what they actually charge, and how they stack up against each other.

📅 Data last updated: October 13, 2026 · Source: broadbandmap.fcc.gov

FCC-Verified Coverage: We pull coverage data directly from the official FCC Broadband Map (broadbandmap.fcc.gov) — the most authoritative source for address-level internet availability in the U.S. This means every provider you see listed for your area is confirmed to actually serve your location, not just your zip code.

AI-Assisted Plan Analysis: Our team uses AI-powered data analysis to process provider plan data at scale — cross-referencing speed tiers, pricing structures, contract terms, and promotional periods across thousands of plans. This lets us surface the best actual value, not just the loudest advertised price.

Transparent, Real-World Pricing: We go beyond the intro rate. We track what you'll actually pay after the promotional period ends — including equipment fees, data cap overage charges, and early termination penalties — so you're never surprised by your second bill.

Speed Claims We Can Stand Behind: We flag providers that advertise misleading "up to" speeds with little real-world consistency. Our rankings prioritize providers delivering reliable upload and download performance — especially important for remote work, video calls, and streaming on multiple devices.

Local Provider Intelligence: Beyond the data, we combine public sources — including provider websites, user-reported experiences, and regional availability reports — to give you a ground-level picture of which ISPs genuinely perform in your neighborhood, not just on paper.
