OMNIUS vs Siege Media

Omnius and Siege Media both sell GEO as part of a broader search program, but they start from opposite ends of the specialist-versus-generalist spectrum. Omnius partners exclusively with SaaS, fintech and AI companies, and treats that narrowness as the whole point — deliberately capping new client onboarding at 8 per year to keep senior-level attention on each account. Siege Media, founded in 2012 and now running offices in San Diego, Austin, Chicago, New York City and San Francisco, serves a far wider industry spread — SaaS, fintech, e-commerce, healthcare, travel, education, real estate and cybersecurity among them — built for brands that want an established, larger-scale engine rather than a boutique relationship.

The two also reach AI-answer visibility through different mechanics. Omnius frames GEO as an amplifier layered on an SEO foundation: technical and content SEO first, then schema/JSON-LD, an llms.txt file, entity and citation engineering, and AI-crawler optimization on top. It has built its own AI-native tooling, Atomic AGI, to track AI search visibility, audit sites and automate optimization tasks in-house. Siege Media instead leads with data journalism and digital PR — original-research content and earned placements designed to be cited by both humans and LLMs — supported by two proprietary planning tools: BlueprintIQ, which scores relevancy-adjusted keyword difficulty and surfaces content gaps and a site's freshness scorecard, and DataFlywheel, which systematically refreshes existing pages on a quarterly-or-faster cadence so older content doesn't decay out of AI answers.

Neither publishes a rate card — both are custom, retainer-based engagements you scope on a call. Each backs its pitch with one named, numbers-attached case study: Omnius grew SaaS client Myos's signups 227.9% in six months (11,000 keywords ranked, 500+ in the top 10, referring domains growing from 96 to 186, 130+ pages published); Siege Media's bottom-funnel software-comparison content helped Mentimeter earn 124,000 ChatGPT sessions over a six-month period and 3,400 conversions in a single month. Both results are real and dated, but they're not directly comparable — one measures classic SEO-ranking and link growth, the other measures AI-chat referral sessions directly.
