What Power Digital does
Power Digital is a US-headquartered growth agency with around a thousand staff and a service menu that spans paid media, SEO, content, lifecycle, creative, and CRO. The pitch on powerdigitalmarketing.com centers on Nova, the agency's proprietary intelligence platform that ties marketing data, customer data, and forecasting together for the account team. Engagements are typically scoped retainers with a cross-discipline pod assigned to the brand. Power Digital sits in the tech-enabled agency category, betting that its software plus services model gives it an edge over pure-play retainer shops. AI search and GEO are inside the SEO and content practice rather than a standalone product.
What Geology does differently
Geology is a single-purpose platform for the AI answer layer. The platform tracks brand visibility across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews, then converts measurement into execution. Page audits flag pages an AI is misreading. Prompt management captures the buyer questions worth ranking on. Content briefs translate gaps into ship-ready work. An agentic optimization layer applies repetitive fixes (schema, FAQ structure, internal linking) automatically. Against a tech-enabled agency model, the difference is depth versus breadth. Power Digital's platform is built to integrate many marketing channels for an account team. Geology's platform is built to run the AI search optimization loop end-to-end, with the agentic layer doing work a retainer pod would otherwise charge hourly for.
Pricing
Power Digital is sold on custom retainers, often layered with a Nova platform fee. Pricing scales with media spend and scope. Geology is a transparent subscription with public pricing tiers, no procurement cycle, and no platform fee on top. For a team that wants AI visibility specifically, Geology runs at a small fraction of a Power Digital retainer.
When Power Digital wins
If you want a single partner to run the whole growth motion, plus a data platform that ties media, ecommerce, and CRM data together, Power Digital is a strong enterprise pick. The combo of services and Nova works well for brands that do not want to assemble that stack themselves.
When Geology wins
If your priority is winning in AI answers and you want a software-led execution layer, Geology is the fit. Same-day data, transparent subscription, and an agentic optimization loop that runs continuously rather than on a retainer cadence. For teams that already have growth handled elsewhere, the focus is the differentiator.
