SEO, AEO and GEO: What's the Difference and Which Does Your Business Need in 2026?

What is SEO?

SEO (Search Engine Optimisation) is the practice of improving your website so it ranks higher in Google and other search engine results pages.

SEO covers three main areas: technical SEO (how well search engines can crawl and index your site), on-page SEO (keywords, headings, content quality), and off-page SEO (backlinks and domain authority). Getting SEO right is the foundation. Without it, AEO and GEO have nothing solid to build on.

SEO is measurable. You can track keyword rankings, organic traffic, and click-through rates. It takes time — typically three to six months for new content to rank — but the payoff is durable, compounding traffic that doesn't stop when you stop paying for ads.

Most businesses in the Netherlands and wider Europe are underinvesting in SEO. They rely on paid ads for visibility, which means the moment the budget runs out, so does the traffic. A strong SEO foundation keeps you visible for years, not weeks.

What is AEO?

AEO (Answer Engine Optimisation) is the practice of structuring your content so that AI tools like ChatGPT, Perplexity, and Claude cite your website when answering user questions.

Where SEO focuses on ranking in a list of results, AEO focuses on being the answer. AI assistants pull from well-structured, authoritative content when generating responses. If your content contains standalone citable sentences, FAQ-style answers, and clear definitions, AI tools are far more likely to reference your business.

AEO tactics include writing FAQ sections where the first sentence is a complete, self-contained answer, adding definition passages for key terms your business is known for, structuring content with clear headings and short paragraphs, and implementing FAQPage schema markup so search engines understand your Q&A content.

According to Salesforce's 2025 holiday season data, AI search referrals convert 9x better than social media traffic. That single stat explains why AEO is now a business priority, not just a technical nice-to-have. Customers who arrive from an AI citation are further along in their decision-making process and far more likely to convert.

What is GEO?

GEO (Generative Engine Optimisation) is the practice of making your content readable and extractable by AI-powered search features such as Google AI Overviews, ChatGPT Search, and Perplexity.

GEO is closely related to AEO but focuses specifically on how AI search engines process and summarise information. Where AEO helps AI chatbots cite you in conversations, GEO helps AI search engines feature your content in their generated summaries and overviews.

GEO techniques include writing in short, single-idea paragraphs, naming entities explicitly (repeating your brand name and product names rather than using pronouns), stacking multiple schema types per page, and ensuring your site allows AI crawlers like GPTBot, ClaudeBot, and PerplexityBot to access your content.

One of the most important GEO signals is content freshness. Research from Searchable (April 2026) found that 76.4% of ChatGPT's top-cited pages were updated within the last 30 days. Regularly refreshing your content — even minor updates — keeps your pages in active consideration for AI citation.

SEO, AEO and GEO: Key Differences

Which does your business need?

All three. SEO, AEO and GEO work together, not against each other. The content that ranks well on Google is often the same content that gets cited by ChatGPT and featured in AI Overviews. The disciplines share the same foundation: high-quality, well-structured, authoritative content. Where you start depends on where you are now.

Not sure where your business sits right now? A visibility audit will show you exactly which gaps are costing you traffic and citations. Thrivng Tech runs SEO, AEO and GEO audits for founders and e-commerce businesses across Amersfoort, Utrecht, Amsterdam, and remotely worldwide.

How to get started with all three

This is the exact process I follow when onboarding a new client for SEO, AEO and GEO work. It's repeatable, measurable, and works for both e-commerce stores and service businesses.

1. 1

   Audit your technical SEO first.

   Crawlability, indexing, page speed, and mobile experience. Use Google Search Console to check for crawl errors, sitemap issues, and pages blocked by robots.txt. Fix these before writing a single word of content — technical issues will undermine everything else.

2. 2

   Add a FAQ section to every key page.

   Write answers where the first sentence is a complete, standalone response. Not 'It depends' or 'Yes, absolutely.' A direct answer: 'FAQPage schema is a structured data format that tells AI search engines which content on your page is a question and which is the answer.' That sentence can be lifted and cited without any context.

3. 3

   Write definition passages for any term your business is known for.

   These are the passages AI engines extract. Start with the term name: '[Term] is...' or '[Term] refers to...' Keep the definition under 60 words and make sure it includes your brand name or product name explicitly.

4. 4

   Implement schema markup.

   At minimum: FAQPage schema on pages with FAQs, Article schema on every blog post. For product pages, add Product schema with pricing and availability. For your homepage, add Organization schema with your full address and contact details. Schema is how machines read your content.

5. 5

   Check your robots.txt.

   Make sure GPTBot, ClaudeBot, and PerplexityBot are not blocked. Many sites block these crawlers without realising, which means AI engines have no data to cite from. Check your robots.txt file and explicitly allow the AI crawlers you want indexing your content.

6. 6

   Monitor your AI citations.

   Search for your business and key services in ChatGPT and Perplexity at least monthly. Are you being cited? Are competitors being cited instead? This tells you where your content gaps are and which FAQs or definition passages to add next.
