Until recently the question was "how do we reach page one on Google". Today your customers ask ChatGPT, Gemini and Perplexity — and get a single answer, with no ten blue links and no page two. SEO isn't dead, but it has a partner now: GEO — Generative Engine Optimization. Here's the practical difference, and why skipping either one leaves money on the table.
SEO — being a result
Classic search optimization makes your site rank high in search results: keywords, quality content, links, speed and a sound technical foundation. The user gets a list of results — and decides whether to click you.
GEO — being the answer
AI engines don't show a list — they give an answer. When a customer asks "which agency should I use for AI implementation?", the engine composes one answer from the sources it crawls and trusts. GEO is the work that puts your brand inside that answer: content structured as direct answers, Schema that machines can read, mentions in sources the engines rely on, and an llms.txt file that guides their crawlers.
Three differences that change the work
Measurement: in SEO you track rankings and clicks; in GEO you track share of answers — what percentage of relevant queries mention your brand, and in what context.
Content structure: Google forgives long, meandering pages; AI engines quote short paragraphs that answer one question precisely. Every page should ask and answer.
Authority sources: in SEO links move rankings; in GEO mentions — even without a link — in the sources the engine reads (guides, comparisons, reviews) are what get you into the answer.
Why you need both
AI engines don't reinvent the internet — they lean on existing search and indexes. A site Google can't see barely exists in AI answers either. SEO is the foundation and GEO is the floor above it: first a healthy, indexed site, then content and presence that AI engines choose to cite.
How to start
Start with a visibility check: ask the major engines the questions your customers ask, and see whether you're in the answer — and who is. From there you derive the plan: infrastructure fixes, question-and-answer content, and building mentions in the right sources.
FAQ
Does GEO replace SEO?
No. AI engines rely on indexed sources and search results, so good SEO is a precondition for good GEO. The work is complementary.
How long until GEO shows results?
Infrastructure and content changes are picked up within weeks; building presence in authority sources takes months. You measure share of answers over time, like rankings.
How do I check if my brand appears in AI answers?
Run a fixed set of relevant queries against ChatGPT, Gemini and Perplexity at regular intervals and log the mentions. That's exactly part of our service.
