Digital Third Coast
Digital Third Coast is a Chicago search marketing agency founded in 2007 that specialises in SEO, paid media and digital PR, blending data journalism with digital PR to produce link-earning campaigns. It now runs dedicated generative engine and answer engine practices aimed at ChatGPT, Perplexity, Gemini, Google AI Overviews and Microsoft Copilot.
It is the only agency in this set that publishes separate, fully built GEO and AEO service pages rather than a single catch-all AI page, and it pairs them with in-house digital PR, which is the earned-media signal LLMs actually cite. It holds a 4.9 rating across 54 verified Clutch reviews.
You want AI search visibility built on earned media and digital PR rather than on-page tweaks alone.
- Nearly two decades in search, operating in Chicago since 2007
- Separate GEO and AEO practices, plus AI platform visibility audits
- In-house digital PR team that earns the press mentions AI models tend to reference
- Clutch lists a 10,000 dollar minimum project size, which prices out smaller local budgets
- Team size is listed at 10 to 49 people, so capacity is smaller than a national agency
Comrade Digital Marketing

It calls its combined organic and AI approach search everywhere optimization, arguing that without a solid SEO foundation there is nothing for AI to cite.

With 69 verified Clutch reviews it has the largest review base of the Chicago agencies here.

Why work with a SEO agency in Chicago
Chicago agencies lean on earned media more than most. Two in this list run in-house digital PR, which matters because press mentions are exactly what AI models cite.
Independence is the pattern here. Four of the six have been owner-operated since 2010 or earlier, which tends to mean senior people stay on accounts.
Published minimums range from 1,000 dollars to 10,000 dollars per project, with hourly rates up to 300 dollars where disclosed.
