Why use a GEO consultant?

Specialized expertise rare on the market

The GEO remains emerging discipline in France with few truly operational experts. GEO consultants master ingestion mechanisms and Quote by LLMs, include differences between engines (ChatGPT vs Perplexity vs Claude), and have developed specific tracking and optimization methodologies.

This expertise cannot be improvised: it is the result of hundreds of hours of testing, analysis of citation patterns, and a detailed understanding of how Large Language Models work. GEO consultants have invested this time in learning and experimenting that your internal team probably doesn't have.

Visibility on growth channels 2025-2026

ChatGPT orders now 9% of all global digital queries at the end of Q2 2025, according to First Page Sage, representing a significant portion for a recently emerged platform (Source First Page Sage). With 800 million weekly active users in 2025, ChatGPT became the 6th most visited site in the world DemandSage, establishing conversational engines as a major channel for information discovery, especially for qualified B2B audiences.

Do not optimize for GEO = losing visibility on channels that now represent nearly 10% of global requests and continuing its rapid growth. A GEO consultant secures your presence on these new channels before competitive saturation, positioning you as early adopter with sustainable competitive advantage.

Measurable ROI via quotes and indirect traffic

Contrary to popular belief, GEO generates Measurable ROI : increase brand quotations in LLMs responses, indirect traffic (users discover brand via AI and then visit site), strengthening sectoral authority, thought leadership positioning, and early adopter advantage over competitors who are still absent from these channels.

GEO consultants have developed adapted measurement frameworks to these new KPIs, allowing precise ROI monitoring and investment justification to management.

How do you choose your GEO consultant?

Verify demonstrated expertise

Ask concrete evidence : is the consultant himself quoted by LLMs on GEO requests? Has he published reference content on the subject? Does it have case studies with measurable results (before/after quotations, indirect traffic generated)?

Beware consultants who are self-proclaimed “GEO experts” without verifiable track record. The discipline is recent but some actors already have several months/years of operational experience proving their real mastery.

Evaluate technical vs editorial approach

Some GEO consultants prefer approach technique (llms.txt file, structured data, architecture). Others focus on editorial (snippet-ready content, question and answer formats, your citability). The best ones master both dimensions and adapt according to your needs.

Identify your priority need: site technically ready but content weak? → Editorial consultant. Good content but architecture not optimized? → Technical consultant. Ideally, aim multi-skilled consultant or complementary duo.

Check technical stack compatibility

If your site is on Webflow, prefer consultants who master this platform or contact our Webflow agency whom integrates GEO natively into its creations with technical optimization from the design stage. If WordPress, make sure the consultant is familiar with the plugin ecosystem and specific technical constraints.

The technical stack strongly influences GEO implementation: what works on Webflow does not necessarily translate identically to WordPress or Shopify. Stack compatibility = time savings and efficiency.

Request methodology and precise deliverables

A serious GEO consultant clearly explains his methodology : what steps, what deliverables, what deadlines? GEO audit should include technical, editorial, competitive analysis AND prioritized actionable recommendations. Monthly support must specify scope of interventions and KPIs monitored.

Beware of vague offers or “GEO all-inclusive package” with no details. Methodological transparency = guarantee of professionalism and results.

Frequently asked questions about GEO

What is GEO (Generative Engine Optimization)?

The GEO (Generative Engine Optimization) refers to the optimization of content to be cited and recommended by conversational engines (ChatGPT, Perplexity, Claude, Gemini). Unlike SEO, which aims to rank in Google results, GEO targets Appeared in answers generated by LLMs. This involves specific structuring: snippet-ready content, advanced structured data, llms.txt file, and architecture facilitating ingestion by AI.

What is the difference between SEO, AEO and GEO?

The SEO optimizes for traditional search engines (Google, Bing) with the aim of appearing in organic results. AEO (Answer Engine Optimization) targets featured snippets and direct answers on Google. The GEO goes further by optimizing for conversational engines where users never have access to traditional results. In practice, these three disciplines complement each other: a well-optimized site performs on all three channels simultaneously.

What is the budget for a GEO consultant?

Freelance GEO consultants generally charge between €500 and €2,000/day according to expertise. A comprehensive GEO audit costs between €1,500 and €5,000. The monthly support is between €800 and €3,000 for agencies, or €3,000 to €10,000/month for senior consultants on complex missions. These rates reflect the scarcity of expertise and the strategic value of the canal for 2025-2026.

Does GEO work for all sectors?

The GEO performs particularly well for information sectors : SaaS, consulting, training, health, health, finance, legal, tech. Direct transaction requests (“buy X”) remain less suitable for GEO. However, even e-commerce benefits from GEO on pre-purchase queries (“best X for Y”, “how to choose Z”). Assess with a consultant whether your sector and target research intentions are Geo-compatible.

How long to see GEO results?

The first GEO results usually appear under 2 to 4 months : sporadic quotations in LLMs, first brand mentions in conversational responses. Significant visibility and recurring demand 6 to 12 months continuous optimization. GEO remains a young discipline where best practices are evolving rapidly: continuous support on 12+ months maximizes lasting results.

How to measure GEO performance?

Several KPIs allow you to track GEO performance: high citation frequency in ChatGPT/Perplexity/Claude responses on target requests, position in cited sources (1st source vs 5th), indirect traffic (users discovering brand via AI and then visiting site), increased brand searches following LLM exposure. Tools like AI Rank Lab or manual methodologies allow this monitoring. Consultant GEO must offer an adapted monitoring dashboard.

Are GEO and SEO compatible?

Absolutely. The GEO amplifies SEO rather than replacing it. GEO optimizations (structured content, schema.org data, semantic architecture) also reinforce classic SEO performances. Conversely, a site with solid SEO bases (authority, backlinks, quality content) leaves with an advantage for GEO. The optimal strategy combines both: SEO for classic Google traffic + GEO for visibility (conversational engines).
