SEO vs. GEO: what advertising agencies have to relearn
SEO and GEO sound related but are two disciplines with different logic. SEO gets your clients to position one on Google. GEO makes sure ChatGPT, Perplexity and Google AI Overviews name them as an answer at all. For advertising agencies this means: a well-rehearsed craft has to be rethought, because the AI doesn't show a ranking list but delivers a single recommendation.
Why the topic hits agencies of all people
Advertising and marketing agencies have made SEO a fixed revenue component over the last fifteen years. Keyword research, backlink building, technical audits, content calendars, all of that is second nature. That's exactly why GEO is uncomfortable for you: not because it's harder, but because it scratches at familiar reflexes. When a client asks why they don't show up in ChatGPT, the tenth keyword list won't help you. You need a new explanation and a new approach.
The pressure comes from two sides. Clients read in the press about AI search and expect answers from you. At the same time, organic click-through rates are dropping for many, because Google AI Overviews already delivers the answer at the top and the user no longer clicks at all. If you don't address this, your agency quickly looks like yesterday's news, and a competitor who explains GEO confidently wins the account.
The good news: your core competencies stay valuable. You can do content, you understand positioning, you think in target groups. GEO builds on that. It's not a devaluation of your knowledge but an extension, if you're willing to throw a few deeply anchored assumptions overboard.
The core difference: ranking versus recommendation
With SEO you fight for positions in a list. Position three is worse than position one, but still visible. There are ten blue links, and with patience almost anyone can slot in somewhere. GEO works more brutally: when a user asks ChatGPT which agency is suited for sustainable brand campaigns, the AI names two or three names, or none. There is no visible position seven. Either you're in the answer, or you don't exist.
That fundamentally changes the mechanics. Google shows what fits a keyword. A language model synthesizes a statement from many sources and makes a selection. It implicitly asks: who is consistently and credibly associated with this topic across the web? So it's not enough to place a keyword often enough on one page. You have to ensure that the same clear picture of your client is painted in many places across the web.
For the agency this concretely means: away from thinking in individual landing pages, toward thinking in reputation and topic ownership. The question is no longer just "Which page do we rank for?" but "For which topic is this client the obvious answer?" That's closer to classic PR and brand management than pure SEO ever was.
What stays from your SEO knowledge and what doesn't
Much of it carries over. Clean technical foundations, a crawlable site, structured data, fast load times, all of that also helps AI crawlers capture your content. Clear information architecture and thematic depth also pay into GEO. Whoever already produces real expert content instead of thin keyword pages has a head start. So your craft hasn't become worthless, it merely shifts its center of gravity.
What no longer carries are the tricks at the margins. Exact keyword density, manipulative link exchanges, doorway pages, meta descriptions optimized to snippet length, a language model cares little about these. It doesn't evaluate a single page against a keyword, but draws statements from the overall picture. An agency that has sold its value through such technical gimmicks has to retell its story.
Honestly: part of the SEO business that rested on volume and repetition will shrink. That's uncomfortable but plannable. Whoever steers early and builds GEO as a standalone service replaces eroding revenue with higher-value consulting, instead of watching the margin slowly erode.
How AI systems find your clients in the first place
Language models draw on two things: on what flowed into their weights during training, and, with systems like Perplexity or Google AI Overviews, on a live search at the moment of the query. For your clients this means: they have to appear both in the broad training corpus, through consistent mentions built up over years, and be currently findable and citable. Both levels need different measures.
Decisive here are mentions on pages the AI classifies as trustworthy: specialist portals, trade directories, press, Wikipedia, reputable blogs. If your client, a mid-sized advertising agency focused on employer branding, only talks about itself on its own website, the AI has little confirmation. If, on the other hand, they appear in specialist articles, case-study collections and interviews with the same clear positioning, they become the likely answer.
This can be measured and steered. You can test which sources Perplexity cites for a typical client question, and deliberately ensure your client appears there. This work is more concrete than the often diffuse SEO everyday routine, it resembles a well-executed digital PR campaign with a measurable goal.
A concrete example from agency everyday life
Take an agency that has specialized in campaigns for regional trade businesses. On Google it ranks decently for "advertising agency trades." But when a client asks ChatGPT "Which agency helps trade businesses with online marketing?", a different name comes up. Why? Because this competitor is linked to exactly this topic in a trade magazine, in two podcasts and in several case studies on industry portals.
The way back into the answer does not lead through more keywords on the homepage. It leads through targeted topic ownership: a specialist article on pricing in trade marketing, an interview about typical mistakes of regional businesses, a publicly documented case study with real numbers. Each of these elements is a signal the AI can pick up. Together they form a picture that a single optimized page never produces.
For you as an agency, this is a sellable service with a clear logic. You can show the client where they stand today in AI answers, where the competitor stands, and with which concrete publications the gap can be closed. That's more tangible than the promise of maybe gaining a few Google positions in a few months.
How to package GEO as an agency service
GEO can be cleanly cast into an offering. At the start stands a visibility audit: for defined questions, you check whether and how the client shows up in ChatGPT, Perplexity and the AI Overviews, and which sources the AI names instead. This audit is a strong entry product, because the result is often surprising and immediately obvious to the client. They see in black and white that they are simply missing from the AI answer.
This is followed by implementation: content with real substance, structured data, a clear thematic positioning and, above all, a mention strategy across credible third-party sites. That connects disciplines that in many agencies used to run separately, content, SEO, PR. Whoever brings these teams together has a real advantage, because GEO arises precisely at this interface.
With reporting you have to honestly rethink. There's no clean ranking chart like with Google. Instead you document the share of mentions for typical questions, the cited sources and their development over time. Communicate from the start that GEO results fluctuate and can change between model versions. This honesty protects you from inflated expectations and positions you as a serious advisor.
The thinking errors that now cost agencies dearly
The first mistake is treating GEO as a pure SEO update and simply tacking on a few FAQ blocks. That falls short, because it ignores the core mechanic: AI answers arise from reputation across many sources, not from a single optimized page. Whoever sells GEO as a small technical add-on doesn't deliver what the client actually needs, and burns trust.
The second mistake is waiting. Some agencies hope the hype will fade. But the use of AI search is rising rapidly, especially among younger target groups and in B2B. Whoever only reacts once clients defect has already lost the lead. Building reputation signals takes time, which is exactly why starting early is the real competitive advantage.
The third mistake is exaggeration in the other direction: selling GEO as a miracle cure and giving guarantees no one can keep. No one can promise that a client will permanently appear in every ChatGPT answer. Whoever claims that risks disappointed clients and reputational damage. The middle path is the only tenable stance: take it seriously, explain it cleanly, measure honestly.
How to get your team fit for GEO
Start internally before you sell it. Have your team test the common AI systems with real client questions and document the results. This shared experimentation creates more understanding in a few days than any theoretical briefing. Everyone on the team then sees for themselves how differently an AI answer behaves compared to a Google results list, and why old reflexes don't apply here.
Then build bridges between your disciplines. Sit content, SEO and PR people at one table and let them jointly design a mention strategy for a pilot client. Use this pilot to sharpen your own approach before you roll out GEO broadly. From the insights emerges a repeatable process that you can offer as a standard service.
And position yourself externally as GEO-competent. Your own agency should show up in AI answers on the topic, nothing convinces a prospect more than when ChatGPT names your name in response to the question about GEO experts. This way you live what you sell, and deliver the most credible proof of your competence right along with it.
Common questions
Should we now completely replace SEO with GEO?
No. Google remains the largest traffic channel for most industries, and many AI systems draw on classic search results for their answers. Treat GEO as an additional discipline that builds on solid SEO foundations. A reallocation makes sense: away from pure volume and keyword tricks, toward substance, reputation and topic ownership that benefits both worlds.
How do I explain the value of GEO to a client when there's no clear ranking?
Show it to them live. Put the typical questions of their target group to ChatGPT or Perplexity and let them see whether they show up and who gets named instead. This moment is more convincing than any metric. Afterward you document the share of mentions and the cited sources over time. Be honest that results fluctuate, that makes you more credible than inflated guarantees.
Can small agencies without a big PR budget also offer GEO?
Yes, for small agencies in particular it's an opportunity. GEO rewards focus and topic ownership, not budget size. A specialized agency can become clearly findable for its niche by being deliberately present in relevant specialist sources. That's achievable with specialist articles, interviews and documented case studies even without expensive PR campaigns, as long as the positioning is sharp and consistent.
