The state of SEO in 2026
SEO is not dead. Let us stop with this self-fulfilling prophecy that digital marketing gurus repeat to sell their latest course. SEO remains the foundation of digital visibility.
But it has become insufficient. And that is an important distinction.
In 2026, Google still accounts for 92% of search in Europe (source: Statcounter, Dublin). Blue links still exist. Organic traffic remains the most profitable acquisition channel in the long run. The fundamentals of SEO -- quality content, backlinks, technical architecture -- still work.
What has changed is the context. Google AI Overview is eating into traffic from classic positions 1-10. ChatGPT and Perplexity are diverting a growing share of informational queries. "Zero-click search" now exceeds 65% on certain query categories in Europe.
SEO places you in the index. But the index alone is no longer enough to generate traffic. You also need to be in the responses.
The emergence of AEO
AEO was born from this observation. AI answer engines do not work like search engines. They do not rank pages: they synthesise responses. Optimisation techniques must therefore adapt.
AEO does not replace SEO. It complements it. Think of it as an additional layer:
- Layer 1: SEO = being in the index (Google, Bing)
- Layer 2: AEO = being in the responses (ChatGPT, Perplexity, AI Overview, Gemini)
Without layer 1, layer 2 does not work (AI engines draw from search indexes). Without layer 2, layer 1 gradually loses its effectiveness (traffic is diverted to AI responses).
Detailed comparison: SEO vs AEO
| Dimension | SEO | AEO |
|---|---|---|
| Primary objective | Rank in search results | Be cited in AI responses |
| Target | Ranking algorithms (PageRank, etc.) | Understanding and synthesis systems (LLMs) |
| Key metric | Position, organic traffic, CTR | AI Visibility Score, citations, mention share |
| Optimal content | Long, keyword-rich, internal links | Q&A structure, direct answers, tables, sourced statistics |
| Backlinks | Ranking factor #1 | Important + non-linked mentions count too |
| Structured data | Recommended (rich snippets) | Near-mandatory (AI comprehension) |
| Freshness | Variable depending on query | Critical for AI engines with web access |
| Key file | robots.txt, sitemap.xml | llms.txt, enriched Schema.org |
| Competition | 10 positions on page 1 | 1-5 sources cited per response |
| ROI timeline | 3-6 months for first results | 4-8 weeks for first citations |
| Average budget (SME) | EUR 1,000 - 5,000/month | EUR 1,500 - 3,000/month (in addition to SEO) |
Gianluca Fiorelli, international SEO consultant based in Barcelona, highlighted at Search Y 2025: "The SEO vs AEO debate is a false debate. It is like asking whether you need an engine or wheels for a car. You need both. The real debate is: how to allocate your budget between the two."
How to combine SEO and AEO
The good news: 80% of optimisations are shared. SEO and AEO share the same fundamentals. Here is how to combine them effectively:
Phase 1: SEO Foundation
Ensure your technical SEO is solid: indexation, speed, mobile-first, HTTPS, internal linking, backlinks. This is the foundation without which nothing works.
Phase 2: AEO overlay
On your existing content, add AEO optimisations: direct answers at the start of sections, enriched structured data, FAQ with Schema.org, sourced statistics, llms.txt.
Phase 3: AI-first content
New content conceived from the start to be both well-ranked in SEO AND cited by AI. This is the complete GEO framework.
Phase 4: Dual monitoring
Track your classic SEO metrics (positions, traffic) AND your AEO metrics (AI Visibility Score, citations). Respond on both fronts.
Practical cases
Case 1: B2B SaaS with good SEO, zero AEO
Typical situation: ranking positions 1-3 on strategic keywords, but absent from ChatGPT and Perplexity responses. Result: organic traffic down 20% over 12 months due to AI Overviews. Solution: AEO overlay in 6-8 weeks, recovery of lost traffic + new AI citations.
Case 2: Startup with neither SEO nor AEO
Recent site, little content, no authority. The "GEO-first" approach is the most effective: create content optimised from the start for both SEO AND AEO. The first AI citations arrive in 4-6 weeks (faster than classic SEO). SEO is built in parallel.
Case 3: E-commerce with strong organic traffic
Organic traffic represents 60% of revenue. AI Overviews appear on product queries. Risk: gradual erosion of traffic. Solution: optimising product pages for AI Overview (Product structured data, comparisons, FAQ), plus creation of informational AEO content for intent queries.

FAQ
Do you have to choose between SEO and AEO?
No. Both are complementary and necessary in 2026. SEO feeds the search indexes that AI engines rely on. AEO optimises how that content is extracted and cited by AI. The optimal strategy combines both.
What budget should be allocated to AEO versus SEO?
In 2026, we recommend a ratio of 60% SEO / 40% AEO for most B2B companies. This ratio will shift towards 50/50 by 2027 as AI engines gain market share. For startups without an SEO history, a 50/50 ratio from the start is often more effective. See our pricing.
Is AEO faster than SEO?
For initial results, yes. The first AI citations (ChatGPT, Perplexity) generally appear in 3 to 6 weeks, compared to 3 to 6 months for classic SEO. This is explained by the nature of AI engines: they re-crawl the web more frequently than Google re-indexes pages.
Does my SEO agency do AEO?
Probably not. As of March 2026, fewer than 15% of European SEO agencies offer structured AEO services. Most traditional agencies still focus exclusively on classic Google ranking. Ask the question directly: "Do you measure our citations in ChatGPT and Perplexity?"
Will SEO disappear?
No. SEO will evolve, not disappear. Classic search engines remain the information source for AI engines. Good SEO is a prerequisite for AEO. What will disappear is SEO as the SOLE digital visibility strategy. You now need to combine SEO + AEO.
Which KPIs should be tracked for SEO vs AEO?
SEO: positions, organic traffic, CTR, bounce rate, conversions via organic. AEO: AI Visibility Score, number of AI citations, mention share, AI referral traffic (visible in GA4), source rank in responses. Ideally, track both sets of KPIs in a unified dashboard.
Conclusion
The SEO vs AEO debate is a false debate. In 2026, you need both. SEO builds your foundation in search indexes. AEO transforms that foundation into AI citations and recommendations.
Companies that only do SEO are losing ground every month. Those that only do AEO lack a foundation. Those that combine both strategically are gaining a considerable lead.
The rules have changed. The game is now SEO + AEO, or nothing.
