The 10 Best SEO Agencies in Chicago

SEOLEVELUP suits Chicagoland small businesses that want SEO, map listings and a website from a single local contact. Based in Oakbrook Terrace, it has served the area since 2003. Services include on-page and technical SEO, schema markup, map listing optimization and work on visibility in AI answers. Phone and text lines are open from 7am to 11pm every day, and a free SEO audit comes before any engagement.

RedShark suits contractors and home service companies that want local search work without a long commitment. Plans are priced by the number of service areas covered and run month to month, with a 30-day money-back guarantee. The work centers on map listings, reviews, citations and AI search visibility, and a website comes with the marketing plans. Clients include roofers, remodelers and tuckpointing firms, so trade businesses can ask for examples from their own field.

Loud Interactive suits large content sites and online stores that need SEO produced at scale. The River North firm offers done-for-you SEO, content production, search-ready web development and online reputation management. Brent D. Payne, whose background includes search work at Groupon and Tribune, is featured as the team's lead. Clients range from Shopify stores and publishers to travel, deal and edtech sites, and work is billed through retainers.

Sixth City Marketing suits mid-size companies that want SEO handled by an in-house team with a named strategist. Its River North office covers technical, local, ecommerce and B2B SEO, link building, content and audits, without outsourcing. Each client is assigned an account manager and a strategist. The agency also builds WordPress and Shopify sites and runs PPC, which helps when a redesign and an SEO program happen together.

EMSC suits home service companies, medical practices and law firms that want SEO judged by the calls and revenue it brings in. The agency on North Ashland Avenue combines SEO, local search, content and PR with search ads and Local Services Ads. Its attribution service connects call tracking and CRM data to each channel, and it monitors how brands appear in AI answers. Multi-location operators and private equity-backed groups are also among its clients.

Operation Technology suits law firms and online stores that want SEO combined with hosting and site maintenance. The Wacker Drive agency lists local, technical, lawyer and ecommerce SEO as its specialties and has offered SEO since 2009. It also designs WordPress and ecommerce websites, writes content and manages paid search campaigns. Its industry list includes accounting, construction, cannabis and solar firms, and quotes are built around each business.

Digital Third Coast suits brands that want SEO driven by content and digital PR rather than technical fixes alone. The agency has worked from Chicago since 2007 and pairs PR with SEO to earn press coverage and links. It also handles paid search, paid social and visibility in AI answers. The standard agreement runs six months before going month to month, and the team expects six to nine months for larger SEO gains.

VisualFizz suits mid-market and enterprise B2B companies that want SEO inside a broader marketing program. The agency on North Michigan Avenue has worked since 2016 and groups SEO with paid search and content in its search team. Branding, web development, social media, video and events sit under the same roof. Its industry focus includes technology and SaaS, manufacturing, industrial and construction, so it suits firms selling to other businesses.

Comrade suits owner-run home service companies that want SEO, ads and the website handled by one team. The Loop agency works only with trades such as roofing, HVAC, plumbing, remodeling and masonry, aiming at firms with $1 million to $10 million in revenue. Its search work covers local SEO, audits and optimization for AI tools like ChatGPT and Perplexity. Bundled programs start at $4,000 a month, so it fits established contractors rather than start-ups.

Marcel Digital suits B2B companies whose SEO is tied to a demanding website build. Its search team handles technical SEO, migrations, penalty recovery, link building and answer engine optimization. The Wacker Drive agency is also an Umbraco Platinum Partner and builds HubSpot and headless sites, so search and development sit under one roof.
