Screaming Frog SEO Spider is the desktop crawler many in-house technical SEOs use to pull a site, surface technical issues, and export the data for their own analysis. Geology is an AI-driven SEO and GEO agency with a different scope: AI agents run strategy and execution, the team ships the work (technical SEO, content, schema, internal linking, off-site citations), and visibility is tracked weekly across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews. If you have an in-house technical SEO who wants a crawler to run themselves, Screaming Frog is that tool. If you want the technical issues fixed and your search and AI visibility to grow, Geology does that work.

What Screaming Frog does
Screaming Frog SEO Spider is a desktop application that crawls websites and surfaces technical SEO issues at the URL level. The homepage lists the standard outputs: redirect chains, broken links, duplicate content, response codes, meta data, structured data validation, JavaScript rendering, sitemap analysis, and integrations with Google Search Console and Analytics. It is one of the most cited SEO tools on G2 for technical work, with a long-running free tier capped at 500 URLs and a paid annual license for larger crawls. Reviewers praise the flexibility; the common point is that Screaming Frog is a crawler, not a service. The data export is the deliverable, and what happens next is on the user.
What Geology does differently
Geology starts where the export ends. Tracking covers ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews with prompt-level granularity, so you see the buyer questions that pull your brand into an answer and the citations that come with it. Page audits connect the dots: they show the exact pages Google or an AI is misreading and explain why (schema gaps, weak entity coverage, thin FAQ structure, missing internal links, technical errors). Then AI agents and the team ship the fixes: technical SEO, content, schema, internal linking, and off-site citations. Screaming Frog gives your team a technical export. Geology gives you the visibility data, the cause analysis, and the shipped fix.
Pricing
Screaming Frog has a free tier capped at 500 URLs and a paid annual license in the low hundreds per year for unlimited crawl size, with no seat-based pricing. Geology starts at $3,000 a month as a done-for-you SEO and GEO engagement. The two are not substitutes on price: one is a crawler license for your team to operate, the other is an agency doing the work.
When Screaming Frog wins
If you have an in-house technical SEO who wants a desktop tool to run their own crawls, validate structured data, or check redirect chains before a migration, Screaming Frog is an inexpensive DIY crawler for that person.
When Geology wins
If your KPI is organic and AI visibility, Geology wins. You get cross-platform measurement, prompt-level tracking, audits aimed at search and AI readability, and an agency that ships the technical and content fixes the same week.
