SEOLEVELUP LLC is a Chicago-area website design and search engine optimization firm headquartered at 1S183 Summit Ave, Oakbrook Terrace, IL 60181. The company has operated since 2003 and reports building over 1,150 websites while ranking more than 800 businesses, serving Chicagoland markets including Chicago, Bolingbrook, and surrounding suburbs as well as national clients.
Core services include custom website design and development, SEO, social media marketing, content and article writing, Google Entity and Authority Stacking, and structured data and schema markup implementation. The firm structures its optimization work around three distinct disciplines: SEO for traditional Google search rankings, GEO (Generative Engine Optimization) for visibility within AI recommendation platforms such as ChatGPT and Gemini, and AEO (Answer Engine Optimization) targeting featured snippets and voice search results.
The company’s stated methodology begins with a free SEO audit, followed by detailed website analysis, competitive research, technical optimization, content refinement, and link building. Every engagement starts with direct communication with an owner, and the firm positions personalized service as a differentiator from larger agencies. Co-founder Tommy Seilheimer brings a background in national sales leadership and entrepreneurship. The company applies Google E-E-A-T content standards across all client projects and focuses heavily on local map-pack rankings and Google Business Profile optimization.
SEOLEVELUP offers both structured packages and fully custom plans. The company backs its work with a 90-day ranking guarantee and states that most businesses see measurable movement within three to six months of engagement. The firm reports accumulating 775 or more five-star reviews across Google, Facebook, and Yelp.
Additional services include PPC management, reputation management, video and animation production, graphic design, local citations, and technical site performance improvements. The team is available seven days a week from 7 a.m. to 11 p.m., providing extended support hours well beyond typical business schedules, which the firm highlights as a service differentiator for time-sensitive client needs.
