Geology and Semrush solve the same problem from opposite ends. Semrush is a wide SEO and SEM software suite with keyword research, backlink data, site audits, and a newer AI Toolkit module for tracking brand mentions in answer engines; your team operates it and does the work. Geology is an AI-driven SEO and GEO agency: AI agents run strategy and execution, the team ships technical SEO, content, schema, internal linking, and off-site citations, and visibility is tracked weekly across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews. If you have a senior in-house team that wants a tool to run SEO research itself, Semrush fits. If you want organic growth in Google and AI answers delivered, Geology does the work.

What Semrush does
Semrush is one of the largest SEO and competitive intelligence platforms on the market. The core product covers keyword research, rank tracking, backlink analysis, site audits, content templates, and PPC research, with adjacent modules for social and local. Its homepage positions the platform as an all-in-one growth toolkit for marketers and agencies. Over the past year Semrush rolled out an AI Toolkit that monitors brand mentions across ChatGPT, Perplexity, Gemini, and Google AI Overviews, with prompt tracking and a sentiment view. G2 reviewers consistently rate Semrush highly for breadth and data depth; the common complaint is the cost stack once you add seats, the AI Toolkit, and Trends.
What Geology does differently
Geology was built from day one for search as it works now, in Google and in generative engines, and it does the work instead of handing you data. AI agents track ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews with prompt-level granularity, so you see which buyer questions surface your brand and which surface a competitor. They find the exact pages Google and AI engines misread. The team then ships the fixes: technical SEO, content, schema, FAQ structure, internal linking, and off-site citations. A suite gives your team more data to act on; Geology acts on it every week. A California-licensed specialty insurance broker went from absent to named in 70% of tracked AI answers, plus 38.7x Google impressions, in six months.
Pricing
Semrush sells tiered subscriptions starting in the low hundreds per month, with the AI Toolkit, extra seats, and Trends priced as add-ons. A working agency stack often lands in the $500 to $1,500 range once everything is enabled, before the cost of the people who run it. Geology starts at $3,000 a month for the full SEO and GEO program, with the execution included.
When Semrush wins
If you have an in-house SEO team that wants a DIY research tool for keyword volumes, backlink data, and PPC research, Semrush gives them that data in one login. It also suits agencies that need white-label reporting across many client accounts.
When Geology wins
If you want organic growth in Google and AI answers without staffing a team to operate a suite, Geology is the agency to hire. You get cross-platform visibility, prompt-level tracking, technical SEO and AI-readability fixes, and content shipped every week.
