GEO for B2B SaaS: What Changes (and What Doesn't) When Marketing Shifts from SEO to AI Search

In a recent episode of The Multilingual Content Podcast, Nicola Calabrese sat down with Joliene van Grieken, Co-founder of The Growth Syndicate, a fractional marketing team that helps B2B SaaS companies scale their marketing across borders. Joliene has spent her career in startup and scale-up environments, leading marketing teams through international expansion . and she has a clear-eyed view of what's shifting now that AI is reshaping how buyers find solutions.

One of the biggest changes. The way companies get discovered online is fundamentally different. And for B2B SaaS companies expanding into new markets, this has real consequences for how you plan your content, your localization, and your go-to-market approach.

Here's what we took away from the conversation

What Is GEO for B2B SaaS

GEO stands for Generative Engine Optimization. It's the practice of optimizing your content so it gets cited in AI-generated answers. The kind of responses people now get from tools like ChatGPT, Perplexity, Claude, and Gemini, instead of (or before) clicking through to a website.

For B2B SaaS companies, this matters because your potential buyers are increasingly starting their research with AI tools rather than a traditional Google search. If your content isn't structured for AI to pick up and reference, you may not show up in the conversation at all, regardless of how well you rank on Google.

GEO builds on SEO. It doesn't replace it. But the success metric shifts: instead of ranking for a keyword, you're aiming for your brand to be cited as a credible answer when someone asks a question relevant to your product or service.

How Is GEO Different from Traditional SEO

As Joliene put it during the episode, traditional SEO is mostly about optimizing for keywords and backlinks. GEO, on the other hand, is focused on credibility, mentions, and clear communication.

The core differences come down to this:

With SEO, search engines look at what's in your H2s, H3s, your keyword density, and your backlink profile. With GEO, AI tools take chunks of your content and present them as answers. They're not ranking pages, they're pulling the clearest, most trustworthy explanation they can find.

That means your content needs to do two things well: be simple and direct enough for AI to extract, and be credible enough, through mentions on other sites, expert authority, and consistent messaging, that AI considers it worth citing.

Joliene made an important point here: if your SEO is already well set up, it will help with AI visibility. But it's not enough on its own.

Why Authenticity Is Your Biggest GEO Advantage

One of the most interesting takeaways from the conversation was Joliene's argument that authenticity is now the single biggest competitive advantage, and the one thing AI can't replicate well.

Her reasoning is straightforward. With AI tools available to everyone, content online is becoming increasingly similar. Every company can produce technically optimized content at speed. The result is a saturated landscape where everything starts to sound the same.

What sets you apart is the perspective, the experience, and the voice behind the content. A great content person with a clear vision, someone who understands who they're writing for and why, creates something that AI-generated content can't match.

This has a direct implication for multilingual marketing. When you expand into new markets, it's tempting to use AI translation to scale content quickly. And while AI can certainly speed up the production process, Joliene warns that too many teams stop thinking about their audience the moment AI enters the workflow. The content becomes a checkbox exercise . technically optimized, but not relevant to the people reading it.

The human has to stay in the loop. Not just for quality control, but for the creative judgment that makes content resonate with a specific audience in a specific market.

What Happens to Your Website in an AI Search World

According to Joliene, the function of the website has been shifting for years . and AI search is accelerating that change.

The traditional model was: potential buyers visit your website, read through different pages, and make a decision. That's no longer how most B2B buying journeys work. By the time someone lands on your website today, they've usually already done their research . on Reddit, through peer recommendations, via AI-generated answers . and they've already got a shortlist.

For B2B SaaS companies, this means the content on your website needs to serve a different purpose. It's not the place where buyers discover you anymore. It's the place where they validate what they've already heard about you.

So what should you optimize for? Joliene points to a few things: make sure your content clearly communicates what sets you apart from competitors. Use FAQs. Write clear, descriptive headers. Use simple language, because AI extracts chunks of text, not entire pages.

And critically, invest in off-site credibility. This is where the game has shifted most.

That credibility from external sources is what signals to AI tools that your brand is worth citing.

We explored this shift in depth with Alex Casals of Tacmind, who described the same two-pronged approach: optimize your owned content for AI extraction, and build third-party credibility through mentions, reviews, and co-citations.

Why GEO for B2B SaaS Requires a Localized Approach

Here's where things get particularly relevant for companies expanding internationally. GEO is not something you can do once in English and assume it transfers across markets.

Joliene shared a perspective that resonates strongly with what we see at Undertow: companies, especially US-based ones, often treat Europe as a single market. They assume that a campaign that worked in one country can be copy-pasted to the next. But buyer behavior, trust signals, industry dynamics, and even the way people use AI tools vary significantly from country to country.

This applies directly to GEO. The AI-generated answers a buyer in Germany gets are not the same as what a buyer in the Nordics sees. The sources AI pulls from, the language it favors, and the credibility signals it weighs are all market-specific.

That means your GEO strategy needs localization, not just translation, but genuine adaptation. Your content in each market needs to be structured for AI extraction in that language. Your off-site credibility needs to exist in local sources, not just English-language ones. And your messaging needs to reflect the specific pain points and buying behaviors of that market's audience.

As Joliene noted, even markets that seem similar . like the Nordics and Germany . have fundamental differences. In Germany, you still need to localize, you need local presence, and you can't expect English-only content to build credibility. The same applies to France and other key European markets.

This connects to what Hugo Pereira shared about cultural nuances: the same product often requires completely different messaging depending on the market. In the context of GEO, this means your content strategy has to be built per market, not just translated per language.

How to Build Off-Site Credibility for AI Visibility

One of the most actionable parts of the conversation was around building the kind of external credibility that GEO rewards. Joliene highlighted several approaches:

Partnerships are a powerful lever, especially in European markets. A local partner who already has credibility in your target market can accelerate your visibility. Both with human buyers and with AI tools that track mentions and co-citations.

Events. Particularly small, localized gatherings are making a comeback. Joliene shared an example of an ABM campaign in the Nordics where small, industry-specific events created disproportionate trust and visibility. These events don't have to be expensive. A venue, dinner for 10,15 prospects, and one local sales person can be enough.

Customer stories and case studies matter more than ever. For companies running a product-led growth motion, Joliene recommends investing in video case studies and getting happy customers to talk about your product publicly. This builds the kind of credible, third-party content that both buyers and AI tools look for.

And importantly, all of this needs to happen in the local market, in the local language, with local references. A case study from a US client won't carry the same weight in Germany as one from a German company in the same industry.

This aligns with what Björn Ingmansson of Kognic shared about strategic localization: start with a Minimum Viable Experience, a localized landing page, key customer stories, essential support content, and build credibility from there. And as Filippo Irdi of Orderchamp explained, building local success cases before investing in full localization is what separates companies that gain traction from those that burn through budget without results.

The Bottom Line: What Hasn't Changed

For all the shifts happening in how buyers find and evaluate solutions, Joliene made a point that's easy to overlook: the fundamentals of marketing haven't changed.

People still buy from people they trust. They still make decisions based on whether a solution feels credible, relevant, and right for them. AI hasn't changed human psychology. It has changed the channels and the mechanics of discovery.

What this means for B2B SaaS companies expanding internationally is that GEO is not a replacement for your localization strategy. It's an additional layer that makes your localization strategy more important, not less. The companies that will get cited by AI are the ones that have genuine authority in their market, real expertise, real customer stories, real local presence.

The ones that try to shortcut it with AI-translated content and no local credibility will find themselves invisible in the exact channels where their buyers are now looking.

Key Takeaways

• GEO for B2B SaaS is about earning citations in AI-generated answers, not just ranking in search results. It builds on SEO but requires a focus on credibility and clear communication over keyword optimization.

  
  

• Authenticity is the biggest differentiator. AI can produce content at scale, but it can't replicate the perspective, experience, and voice that make content resonate with a specific audience.

  
  

• Your website's role has shifted. Buyers arrive having already done their research. Optimize for validation, not discovery, and invest heavily in off-site credibility.

  
  

• GEO must be localized per market. AI-generated answers differ by language and region. Your content, credibility signals, and messaging need to be adapted for each market you enter.

  
  

• Off-site credibility is the new backlinks. Partnerships, local events, customer stories, and third-party mentions are what signal to AI tools that your brand is worth citing.

  
  

• The fundamentals haven't changed. People still buy from people they trust. GEO makes your localization and local market credibility more important, not less.

FAQ

What does GEO mean in marketing.

GEO stands for Generative Engine Optimization. It's the practice of optimizing content so that AI tools . like ChatGPT, Perplexity, Claude, and Gemini . cite your brand when answering questions relevant to your product or service. It's sometimes also called AEO (Answer Engine Optimization) or LLMO (Large Language Model Optimization).

Is GEO replacing SEO.

No. GEO builds on SEO . it doesn't replace it. If your SEO foundations are solid, they'll support your AI visibility. But GEO adds new requirements: structured content that AI can extract, clear communication, and strong off-site credibility through mentions and citations on other websites.

Why does GEO matter for B2B SaaS international expansion.

Because buyers in different markets get different AI-generated answers depending on their language, region, and local sources. A GEO strategy that works in English won't automatically work in German, French, or any other language. You need localized content, local credibility signals, and market-specific messaging.

How can a B2B SaaS company start with GEO.

Start by structuring your existing content for AI extraction: clear headers, FAQ sections, answer-first paragraphs, simple language. Then focus on building off-site credibility in your target markets through partnerships, events, customer stories, and getting mentioned on relevant third-party websites and platforms.
