Geology and Volume Nine are both agencies, but they are built differently. Volume Nine is a Denver-based team running SEO, paid and organic social, and content under monthly retainers. Geology is an AI-driven SEO and GEO agency: AI agents run strategy and execution, and the team ships technical SEO, content, schema, internal linking and off-site citations, then tracks visibility weekly across ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews. Volume Nine fits brands that want social media and creative rolled into one retainer. Geology fits brands that want organic search and AI visibility to grow, with fixes shipping every week.

What Volume Nine does
Volume Nine is a Denver-based digital marketing agency focused on mid-market brands. The service menu on v9digital.com covers organic search, paid search, paid social, organic social, content, and analytics. The agency's positioning is built around the integration of SEO and social, with case studies across retail, B2B, and consumer brands. Engagements are monthly retainers with a strategist and channel specialists assigned to each account. Volume Nine has been recognized in Clutch and Inc. agency rankings, and reviews highlight strategic clarity and a senior bench. AI search optimization is part of the SEO conversation rather than a dedicated service line.
What Geology does differently
Geology is built for the AI answer layer first, not adapted from a traditional SEO playbook, and it runs classic SEO in the same engagement. AI agents plan strategy and execution, and the team ships technical SEO, content, schema, internal linking and off-site citations. Visibility is tracked weekly across ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews, alongside traditional rankings. Page audits flag the URLs an AI is misreading, buyer prompts are mapped to the pages that should win them, and fixes go live in days rather than retainer cycles. For a mid-market brand, throughput is the difference: AI agents handle the repetitive validation a billable hour is too expensive to do, so more pages get fixed per quarter. For one mid-size B2B SaaS client, that produced 65% organic growth in six months.
Pricing
Volume Nine engagements are quoted monthly retainers, scaled to scope and channel mix, and typically priced for mid-market budgets. Geology starts at $3,000 a month for SEO and GEO strategy and execution.
When Volume Nine wins
If you want one partner to run paid social, organic social and creative alongside your search program under a single retainer, an integrated multichannel agency like Volume Nine fits that preference. Geology does not run social media, paid media or creative production.
When Geology wins
If the goal is organic search growth and AI visibility, Geology fits. You get cross-platform measurement plus a team that ships technical, content and structural fixes every week, so your in-house marketers can spend time on brand, creative and other channels. Faster cycles and more pages touched per quarter.
