01The shift

Ranking on Google is no longer enough

For twenty years the goal was simple: rank, get the click, convert the visitor. That chain is breaking. A growing share of searches now end inside the results page or inside a chat window — the user reads a synthesised answer and never visits a website at all.

Then

Your ranking earned the click.

Now

The AI answer ends the search.

Has tracked the rise of zero-click searches for years — the growing share of queries that end without a visit to any website.

Pew Research CenterIndependent think tank

Found that users shown an AI summary click through to source links markedly less often than users who aren’t.

Being the number one organic result does not mean an AI engine will cite you.

Google’s own AI Overviews sit above the organic results on an expanding set of queries. These systems select and summarise sources by their own logic — how clearly your entity is defined, how extractable your content is, how often you’re corroborated elsewhere. Plenty of top-ranking pages are invisible inside AI answers.

—What it costs you

01 / 03

The answer replaces the click

Lost sessions

When an AI Overview or chat answer resolves the question, the click that used to reach your site never happens. Your impression still counts. Your session doesn’t.

02 / 03

Rankings and citations are different games

Lost citations

Classic ranking factors get you into the candidate set. Whether an engine actually names your brand in its answer depends on entity clarity, structured data, and third-party corroboration.

03 / 03

Your competitor becomes the default answer

Lost consideration

Ask any AI engine who the best providers in your category are and you’ll get a short list. If you’re not on it, you’re not in the consideration set — and the buyer never knew you existed.

What is Generative Engine Optimization?

GEO builds on SEO foundations rather than replacing them. AI engines still lean heavily on crawled, indexed web content — if a page can’t be crawled, rendered or understood, it can’t be cited either. Technical health, clean information architecture, and genuinely useful content remain prerequisites. GEO adds the layer above: entity definition, structured data, citation-ready formatting, conversational query coverage, and off-site authority.

That’s why we don’t sell GEO and SEO as two engagements. At DeviLabs they are one service, because separating them produces exactly the gap most brands are stuck in — solid rankings, invisible in AI answers.

The short answer

Generative Engine Optimization (GEO) is the practice of making a brand visible, trusted and citable inside AI-generated answers — the responses produced by ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews. Where SEO optimises for a ranked list of links, GEO optimises for being named, quoted and recommended in the answer itself.

In practice that means making your brand unambiguous as an entity, structuring your content so a language model can extract and attribute it cleanly, and building the third-party corroboration that gives an engine confidence to recommend you by name.

03Why DeviLabs

GEO that converts, not just gets cited

Getting mentioned in an AI answer is a means, not the goal. The buyer still has to land on your site, believe what they see, and act. That second half is where most visibility work quietly fails — traffic arrives, nothing happens, and the reporting still looks great.

Half one

AI visibility brings the buyer

Entity clarity, structured data, citation-ready content and third-party corroboration make you one of the brands ChatGPT, Perplexity, Gemini and Google AI Overviews name and link. The buyer arrives pre-qualified and high-intent.

Half two

Performance creative converts them

Years of performance creative for DTC and ecommerce brands — ad creative, video, landing-page assets — work judged on whether it moved a number, not whether it looked good in a deck. That discipline turns the visit into a customer.

DeviLabs came to GEO from the conversion side. One partner for both halves: the visibility that brings the buyer, and the creative that converts them.

04Questions

GEO — frequently asked questions

Book a free consultation call
01What is GEO?

GEO stands for Generative Engine Optimization. It’s the practice of making a brand visible, trusted and citable inside AI-generated answers — the responses produced by ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews. Where SEO optimises for a ranked list of links, GEO optimises for being named, quoted and recommended in the answer itself. It’s also called answer engine optimization (AEO), AI search optimization or LLM SEO. Note that GEO here means generative engine optimization, not geographic or geo-targeting.

02GEO vs SEO — what’s the difference?

SEO aims to rank a page in a list of blue links so a user clicks it. GEO aims to get your brand named and cited inside a generated answer, where there may be no list and often no click at all. The success metric differs: SEO is measured in rankings, impressions and sessions; GEO is measured in citation share across AI engines, how often you’re named versus a competitor, and AI-referred traffic.

The tactics overlap but aren’t identical. SEO leans on keyword targeting, link acquisition and technical health. GEO leans on entity clarity, structured data, extractable content formatting, conversational query coverage and third-party corroboration.

03Do I still need SEO?

Yes. GEO builds on SEO foundations rather than replacing them. AI engines still draw heavily on crawled and indexed web content, so if a page can’t be crawled, rendered or understood, it can’t be cited either. Technical health, clean site architecture and genuinely useful content remain prerequisites.

We treat them as one service for exactly this reason. Splitting them is what produces the gap most brands are stuck in: decent rankings, invisible in AI answers.

04How long until results?

Months, and it compounds. Some technical and schema fixes register within weeks — an engine picking up a corrected entity description, for example. But meaningful movement in citation share generally takes three to six months, because it depends on content being crawled and re-crawled, third-party corroboration accumulating, and model providers refreshing their retrieval sources.

Anyone promising you a fixed timeline to a fixed AI citation position is guessing. AI answers are also genuinely volatile: the same prompt can return different sources week to week, which is why we measure with a fixed prompt set on a fixed cadence rather than reacting to one-off screenshots.

05How do you measure AI visibility?

We build a fixed prompt set — typically 30 to 50 buying-intent questions from your category — and run it across each target engine on a set cadence. For every run we record whether your brand is named, whether it’s named first or in passing, whether your domain is linked as a source, and which competitors appear instead.

Alongside that we track AI-referred sessions by referrer, and branded search impressions and clicks in Search Console. Same prompts, same engines, same method every time, so the numbers are comparable. We publish the methodology with the numbers — a citation-share figure without a stated prompt set and date range doesn’t mean anything.

06Which AI engines do you optimize for?

Primarily ChatGPT, Perplexity, Google Gemini and Google AI Overviews, with Claude and Microsoft Copilot covered where they matter to your audience. The underlying work is largely shared — entity clarity, structured data and citation-ready content help across all of them — but retrieval behaviour differs by engine, so we report per engine rather than as a single blended score.

07Does GEO work for DTC, ecommerce and SaaS?

Yes, though the shape of the work differs. For DTC and ecommerce, buyers ask AI engines for product and brand recommendations, so the emphasis falls on product entity data, category content, review and comparison corroboration. For SaaS and B2B, the questions are more comparative and solution-led (“best tool for X”), so category positioning, comparison content and directory presence carry more weight. For SMBs, the same mechanics apply at a smaller scale: fewer buyers are asking, but the citation set is usually thinner and easier to enter.

What doesn’t change: if your category has buyers asking AI engines what to choose, there is a citation set, and you’re either in it or you aren’t.

08What happens on the free consultation call?

Thirty minutes, straight to the substance: how AI engines choose the brands they name in your category, an honest read on whether your site is citable as it stands, where GEO would move something for you first, and what a sensible first ninety days would look like. You also get a plain explanation of how AI visibility is measured, so you can judge any GEO proposal — ours or anyone else’s.

No cost and no commitment. If GEO is the wrong spend for you right now, you will hear that on the call: book your consultation call here.
