SEO vs. GEO – What’s Changing for Marketers?

Buyers no longer start every search on Google. They ask ChatGPT, Perplexity and Google AI Mode, and get one answer with a short list of vendors. If you're not on that list, you're not in the running.

Ranking on Google still matters. But it's no longer the whole picture. You also need to know how AI models describe you, when they mention you and who they recommend instead.

The difference between SEO and GEO

SEO (search engine optimization) gets your website ranked in search engines like Google and Bing, through technical work, relevant content and links from other sites.

GEO (generative engine optimization) gets your brand into the answers AI models write.

Ask ChatGPT "What are the best CRM systems for a growing B2B company?" and you get a summary: a few vendors, a comparison and a recommendation. GEO is about making sure you're one of them.

In short:

SEO: get found in search results.

GEO: get mentioned, cited and recommended in AI answers.

The two aren't separate disciplines. Both reward relevant content, a technically sound site and credibility.

From keywords to questions

On Google, people type short phrases like "best CRM B2B".

With AI, they ask full questions:

"We're a B2B company with 150 employees using HubSpot. Which marketing automation platform fits best if we want to focus on ABM and lead nurturing?"

The AI reads the context, compares options and suggests a fit. Then the buyer asks a follow-up, without starting over.

So keyword research isn't enough on its own. You need to know the questions your buyers ask, the problems they're trying to solve and what they need to decide.

From rankings to recommendations

In SEO, a higher position means more traffic.

In AI search, the model pulls from many sources and shows a handful of options. The buyer often gets what they need without visiting a single website.

That means AI can shape a buyer's opinion of you before they ever reach your site. The questions to ask change:

How often do AI models mention us?

Which competitors do they recommend instead?

For which needs do they bring us up?

Which sources do they rely on to describe our market?

Do they describe us accurately?

Answering these takes a new way of measuring visibility.

Content has to answer specific questions

Good content has always mattered for SEO. As buyers ask AI more detailed questions, general descriptions of what you do aren't enough.

Strong content:

Explains the problems your product solves.

Compares solutions honestly, including trade-offs.

Says which companies it suits best.

Answers the questions buyers have before they buy.

Shows real customer cases and results.

Clear structure, useful headings and facts help both search engines and AI models understand you. Write for people first. What helps a buyer also helps the model.

Your presence beyond your own website

SEO has long rewarded links and domain authority.

GEO goes further. AI models draw on industry publications, comparison sites, reviews and expert articles when they write an answer.

Publishing on your own site isn't enough. Digital PR, thought leadership and credible third-party mentions now feed directly into how AI describes you. SEO, GEO, PR and brand building are becoming one job.

New ways to measure visibility

SEO has established metrics: organic traffic, keyword rankings, click-through rate and conversions.

They still matter, but they miss how you show up in AI search. Add these:

AI answers change with the wording of the question, the model and the user's context. So GEO needs a clear method. It isn't a one-to-one swap for keyword rankings.

And AI visibility builds awareness and demand even when nobody clicks.

What GEO means for B2B and lead generation

B2B purchases take time. Several people compare vendors, weigh alternatives and build a shortlist.

AI now does much of that research for them. If you're missing from AI recommendations, you miss the shortlist before you know it exists.

The upside: GEO puts you in front of buyers right when they're exploring a problem or comparing options.

It also connects to account-based marketing (ABM). Know the questions your priority accounts ask, and you can build content that wins visibility in both Google and AI.

The next step is tying that visibility to leads, CRM data and revenue. Keep one distinction clear: appearing in an AI answer is not the same as a buying signal from a specific company.

Do you have to choose between SEO and GEO?

No.

Google still drives traffic and conversions. AI search is a second way buyers discover you.

Treat SEO and GEO as two parts of one search strategy. Much of your SEO work already supports GEO: a sound site, clear content and a credible presence count in both.

What changes is how you measure visibility, which buyer behaviour you study and which results you track.

Five things to start doing now

1. Map your AI visibility

Check how ChatGPT, Perplexity and Google AI describe you, and who they recommend instead.

2. Start from your buyers' questions

Add the questions buyers ask at each stage of the journey to your keyword research.

3. Make content more specific

Prioritize content that answers real questions, compares options and helps buyers decide.

4. Build your presence beyond your site

Invest in digital PR, industry publications, thought leadership and credible third-party mentions.

5. Update how you measure

Add AI visibility metrics to your SEO KPIs, and connect them to traffic, leads and revenue.

Search now means SEO and GEO

AI search changes how buyers find, compare and judge brands.

Ranking on Google still matters. Knowing how AI describes you now matters too.

You don't replace SEO with GEO. You combine them.

The companies that bring together search optimization, AI visibility, useful content and a strong brand will reach buyers wherever they search.
