The Ad Firm is a small-to-mid-market digital agency that recently added Generative Engine Optimization to its service menu. Geology is the software a team like that would use to actually do the work. If you are an SMB with no marketing function and you want a single vendor to run paid, SEO, and now GEO under one retainer, The Ad Firm fits the brief. If you have someone in-house and want measurement plus execution for AI search at software pricing, Geology is the better shape. The two can also work together when the agency owns delivery and Geology owns the platform.

What The Ad Firm does
The Ad Firm is a digital marketing agency that targets small and mid-sized businesses across the US. The service menu on theadfirm.net covers SEO, paid search, social, web design, and a more recent Generative Engine Optimization line. The pitch is one account team for the whole digital stack, sized for SMB budgets rather than enterprise. Engagements are monthly retainers with a strategist who runs the account, supported by specialists for paid and content. GEO is positioned as an emerging service rather than the agency's main practice, which is consistent with most full-service shops that have layered AI visibility on top of an existing SEO offering.
What Geology does differently
Geology is purpose-built for AI visibility, not adapted from a traditional SEO playbook. The platform tracks brand presence across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews, then connects that data to the changes that move the metric. Page audits flag URLs an AI is misreading. Prompt management captures the queries your buyers run in answer engines. The content workspace turns gaps into briefs. An agentic optimization layer applies repeat fixes (schema, FAQ structure, internal linking, entity disambiguation) automatically, so the loop from insight to live change runs in days. The contrast with a generalist agency is depth and throughput. Software does the repetitive validation work that a retainer hour cannot afford, which means more pages improved per month at a lower marginal cost.
Pricing
The Ad Firm runs a monthly retainer model sized for SMBs, typically starting in the four-figure range and scaling with services. Geology is a transparent subscription with public tiers, no sales cycle, and no minimum commitment beyond standard subscription terms. For an SMB that already has someone running marketing, Geology lands well below a multi-service agency retainer while covering the AI visibility piece end to end.
When The Ad Firm wins
If you are an SMB owner with no marketing team and you want one vendor to handle paid ads, SEO, content, and now GEO under a single point of contact, an agency is the right shape of solution. The Ad Firm fits that buyer and is sized for it.
When Geology wins
If you have someone owning marketing (a founder, a fractional CMO, or an in-house marketer), Geology compresses the cost of AI visibility work and gives the team the data plus execution layer to ship faster. You keep the strategy in-house and let software handle the repetitive optimization.
