Geology is an AI-driven SEO and GEO agency: AI agents run strategy and execution, and the team ships the work (technical SEO, content, schema, internal linking, off-site citations), then tracks visibility weekly across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews. Titan Growth is a San Diego agency running SEO and paid media on a retainer with proprietary technology in the loop. Choose Geology if organic search and AI visibility are the channels you need to grow, with work shipped the same week. Choose Titan if you want paid search and paid social under the same roof with a sales-led onboarding. Different operating models.

What Titan Growth does
Titan Growth is a San Diego-based digital marketing agency that has been in market since 2004. Their site lists SEO, paid search, paid social, and content as core services, and they highlight TitanBOT, a proprietary crawler used for technical audits and competitive analysis. They serve mid-market and growth-stage brands across B2B and B2C, and pitch an account team model where strategists own the relationship end to end. Public reviews on Clutch and G2 call out longevity in the space and the responsiveness of the account team. As with any retainer agency, the trade-off is retainer pricing and the cadence of human delivery, where audits and content move through account-management cycles.
What Geology does differently
Geology is built around a tight search and AI loop instead of a quarterly retainer rhythm. AI agents track visibility across Google and ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews, run technical audits, and map the queries your buyers run. The team ships the work: technical SEO, content, schema, FAQ structure, internal linking, and off-site citations. The difference is throughput. AI visibility shifts week to week as models retrain, so moving from insight to fix in days outpaces waiting on a retainer roadmap. A B2B engagement on this model cut CAC 35% in six months.
Pricing
Titan Growth is sold as a monthly retainer with custom scope; engagements scale with the SEO and paid budget on the table. Geology starts at $3,000 a month for done-for-you SEO and GEO execution, a fraction of a combined SEO and PPC retainer.
When Titan Growth wins
If you want paid search and paid social managed under the same roof as your other marketing, by one account team, Titan sells that combined retainer. Brands whose procurement prefers a single long-tenured vendor for paid and organic are its fit. Geology does not run paid media.
When Geology wins
If organic search and AI visibility are what you need to move, Geology is the choice. You get SEO and GEO strategy and execution from one agency, a live audit at kickoff, and weekly tracking across Google and the major AI engines. For B2B teams measured against pipeline, the speed from insight to shipped fix is the difference.
