# 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. It is 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, meaning 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.

## FAQ

**What is the main difference between Omnius and Siege Media?**

Omnius is a boutique agency working exclusively with SaaS, fintech and AI companies, capping new client onboarding at 8 per year. Siege Media is a larger, established agency serving many industries (SaaS, fintech, e-commerce, healthcare, travel, education, real estate, cybersecurity) at bigger scale.

**Does either agency publish pricing?**

No. Both Omnius and Siege Media are custom, retainer-based engagements quoted per client after a scoping conversation.

**What proprietary tooling does each one bring?**

Omnius built Atomic AGI, an in-house AI-native platform for tracking AI search visibility, auditing sites and automating optimization tasks. Siege Media built BlueprintIQ (keyword-difficulty scoring, topic discovery, content-gap analysis and a freshness scorecard) and DataFlywheel (systematic quarterly-or-more content refresh).

**Which is a better fit outside the SaaS/fintech world?**

Siege Media. It works across e-commerce, healthcare, travel, education, real estate and cybersecurity brands as well as SaaS and fintech. Omnius partners exclusively with SaaS, fintech and AI companies and is a poor fit outside those verticals.

**What case-study results does each cite?**

Omnius cites SaaS client Myos's 227.9% signup growth in 6 months (11K keywords ranked, 500+ in the top 10, referring domains 96→186). Siege Media cites Mentimeter's 124K ChatGPT sessions over 6 months and 3.4K conversions in one month from bottom-funnel comparison content.
