AEO 2026: why classic SEO is no longer enough
Since 2024, a growing share of B2B and B2C searches transits through Answer Engines: ChatGPT (with search), Perplexity, Claude, Gemini, Le Chat Mistral. Instead of clicking 10 blue links, the user receives a synthesized answer with 3-8 cited sources.
Consequence: to exist in 2026, you must be cited by these engines. This is Answer Engine Optimization (AEO).
The right move: do not replace SEO, but extend it. SEO + AEO = full-funnel visibility.
H2: How LLMs pick their sources
Answer Engines crawl the web (or use a pre-computed index like Perplexity) and select sources by multiple criteria:
| Criterion | Importance | How to optimize |
|---|---|---|
| Domain authority | High | Backlinks, age, trust signals |
| Content structure | Very high | Clear H2/H3, short paragraphs, lists |
| Factual data | Very high | Dated numbers, cited sources, studies |
| Geographic specificity | High | Mentions of Dakar, Senegal, neighborhoods, institutions |
| Recency | High | Visible update date, content < 24 months |
| Schema markup | Medium-high | Article, FAQPage, HowTo, Organization |
| Readability | High | Short sentences, precise vocabulary |
| HTTPS + crawl accessibility | Mandatory | Open robots.txt, submitted sitemap |
AEO-friendly content is content an LLM can cite in 1 sentence without hallucination risk.
H2: LLM-optimized editorial structure
Rule 1: one H2 = one clear question. LLMs extract H2s and match user queries. Example: "How much does a website cost in Senegal in 2026?" > "Pricing".
Rule 2: the answer in 1-3 sentences in the first lines under the H2. The LLM cites this part first.
Rule 3: then develop. Table, examples, nuances. The LLM reads and rephrases.
Rule 4: FAQ JSON-LD mandatory. FAQPage schema = explicit signal for LLMs (cf P5).
Rule 5: dated quantified data. "In 2026, the X market in Senegal is worth Y billion FCFA according to Z" > vague "the market is growing".
H2: Source citations and factual content
LLMs prefer content that cites reliable sources. This reinforces credibility AND gives engines an authority signal.
Sources to cite in 2026 for Senegal/Africa content:
- ANSD (Senegal National Statistics Agency)
- BCEAO (Central Bank of West African States)
- ARTP (Senegal Telecom and Post Regulator)
- World Bank Senegal
- ITU (telecoms)
- McKinsey Africa, Endeavor Africa
- Statista, Similarweb (audiences)
- Africa50, AfricaInvestor sector reports.
Optimal citation format:
"According to ANSD (2025 report), Dakar population reaches 4.3 million inhabitants."

Schemas that help AEO (JSON-LD detail in P5):
- Article: title, author, publication date, modification date.
- FAQPage: structured Q&A.
- HowTo: numbered steps for tutorials.
- Organization: name, logo, contact, sameAs (social networks).
- Person: for expert bio (article authors).
- Dataset: if you publish quantified data (reports, studies).
Effect: LLM engines (Gemini integrated in Google, Bing Copilot, Perplexity) read these schemas and increase citation probability.
H2: LLM citation monitoring
How to know if ChatGPT/Perplexity/Claude cite your site?
2026 tools:
- Otterly.ai: LLM citation monitoring (paid, 50-250 USD/month).
- Profound: enterprise AEO tracking.
- AthenaHQ, Peec AI: specialized alternatives.
- Manual: ask 50 typical queries to ChatGPT/Perplexity/Claude each month, log cited sources.
Metrics to track:

FAQ
Which LLMs dominate Answer Engines in 2026?
Top 5: ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google, integrated in Search), Perplexity, Le Chat (Mistral). In French-speaking Africa, ChatGPT + Claude + Gemini total ~85% of B2B usage.
Does AEO replace SEO?
No. Google SEO remains dominant in volume (Google Search + integrated Gemini). AEO is complementary: it captures the growing share of users going through ChatGPT/Perplexity/Claude directly. The best contents perform on both.
How long for an LLM to cite my site?
Variable. Perplexity may cite from indexing (days). ChatGPT (training) and Claude: citations via real-time web search (days), via knowledge (12-24 months after cut-off). Optimizing for LLM real-time search is faster.
Should content be in French or English?
Both ideally. English for international tech/business audience and better LLM coverage. French for local Senegal/French-speaking Africa audience. Publish both versions with hreflang properly set.
Which formats work best for AEO?
1) Long articles (1,500-3,000 words) with H2 = questions and immediate answers. 2) Quantified studies and data (LLMs love citing numbers). 3) Comparisons/tables. 4) Structured FAQs. 5) HowTo tutorials. Avoid: vague content, pure marketing without data, posts < 500 words.
