Methodology & provenance
How this league is ranked
The league ranks companies registered in Illinois by the OpenRank of their website's domain, floored at 1.0 so only domains the open link graph actually measures appear. OpenRank is a link-authority score — it says how strongly the web links to a domain, and it is not a traffic, visitor or revenue measurement. Rankings refresh on a rolling cache from the multi-country company index; OpenRank coverage in the index is US-only.
