Google Ads and Digital Marketing for Illinois Businesses
Illinois’s largest cities are Chicago and its fast-growing suburbs, plus Rockford in the north. We run campaigns for Illinois businesses from our Freehold, NJ headquarters, by phone and video.
How Illinois markets differ
Four of Illinois’s five largest cities, Chicago, Aurora, Naperville and Joliet, are in the Chicago area, where competition for legal, medical and home-service searches is intense. Rockford is a separate market with a strong manufacturing and aerospace base.
- Chicago: neighborhood-driven search and high competition.
- The western and southwestern suburbs: Aurora, Naperville and Joliet, each with its own customers.
- Logistics: the Joliet/Elwood intermodal complex is described as North America’s largest inland port.
- Rockford: manufacturing, aerospace and air cargo.
