Geology and Skale both work with B2B SaaS, with different operating models. 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. Skale is a productized SEO agency that works only with B2B SaaS companies, running content, technical SEO, and link work on a monthly retainer with a human team. The difference is coverage and speed: Geology works Google and the AI answer engines as one program, on a weekly cycle.

What Skale does
Skale is a UK-based SEO agency that focuses exclusively on B2B SaaS, positioned on its homepage around predictable pipeline from organic search. Services include content production, on-page and technical SEO, conversion-focused page builds, and link acquisition. Clients are typically Series A through Series C SaaS companies that have product-market fit but need a dedicated SEO program without hiring a full in-house team. The model is productized: tiered retainers with defined deliverables per month, plus a strategist and a content team. Reviews on platforms like G2 and Clutch mention the SaaS-specific playbooks and the shipping of category and feature pages.
What Geology does differently
Geology covers SEO and the surface SaaS SEO retainers do not yet own: AI answer engines. AI agents measure every prompt your buyers ask in ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews, score citation share against the competitors winning the slot, and audit pages for the schema, FAQ, and internal-link gaps blocking rankings and citations. The team ships the fixes: technical SEO, content built around your category language and buyer prompts, schema, internal linking, and off-site citations. The angle is cycle time. AI answers shift faster than Google rankings, so work moves weekly rather than waiting on the next sprint. One mid-size B2B SaaS client grew organic traffic 65% in six months, and a B2B engagement cut CAC 35% over the same period.
Pricing
Skale is sold as productized monthly retainers across tiered scopes. Specific pricing is quoted per account. Geology starts at $3,000 a month for done-for-you SEO and GEO execution, covering Google and the major AI answer engines in one engagement.
When Skale fits
If you specifically want a human-only team with no AI agents in the delivery, a productized retainer with fixed monthly deliverable counts, or conversion-focused page builds bundled into your SEO contract, Skale offers that structure. For the SEO and GEO work itself, across Google and AI answers, Geology covers it.
When Geology wins
If you want your SaaS to rank on Google and get cited when buyers shortlist software in ChatGPT and Perplexity, Geology is the choice. You get SEO and GEO strategy and execution in one engagement, a live audit at kickoff, and weekly tracking across the major AI engines. For lean SaaS teams, one agency covering both surfaces beats running two programs.
