Why every agency became an “AI agency” this year
Google search itself has shifted: generated answers (AI Overviews and AI Mode, now available in France) capture part of the clicks that used to reach websites.
On google.fr, the question “how do I choose an SEO agency” gets a generated answer first, and only one website fits on the first screen. Captured on a phone on 13 October 2026.
Businesses see it in their analytics, look for an answer, and agencies adjusted their storefront: the word “AI” appeared on homepages much faster than in working methods.
Telling the two apart takes fifteen minutes of conversation.
Key takeaway
An agency that has genuinely industrialised its SEO with AI can show you three things
- Its engine running
- Its review pipeline
- Its costs
An agency that “added AI” will show you slides. Our SEO and GEO engine is built on those three things, and we show it before you sign.
What an AI SEO engine concretely does
Classic agency SEO moves in batches: an audit, a monthly report, a call, recommendations, then next month it starts again. An AI-assisted SEO engine moves continuously, across four functions:
- Opportunity detection: a regular Search Console scan crosses your actual positions with a keyword objectives registry. Queries within striking distance, pages slipping, titles seen but never clicked: the week’s work comes out of data, not intuition.
- Production: models draft content structured to be cited (a direct answer up top, sourced facts, planned internal linking), in several languages if your market requires it.
- Technical audit: the robots.txt actually served, the sitemap, hreflang, access for AI crawlers (GPTBot, ClaudeBot), and titles rewritten when impressions are there but clicks are not.
- Refreshing: content losing positions gets diagnosed and brought back up to date, facts re-checked and re-sourced, rather than left to slide.
We can describe this mechanism precisely because it is our own engine’s: it has scanned our Search Console every evening since 25 August 2026, and every draft it produces goes through human review before publication. This article is one of its products.
Human review is not optional
The one point never to concede: no generated content should ever be published without human review.
From the field
A client learned this the hard way
On their site, a model invented three projects from scratch inside an article that had already gone live, and it had to be pulled urgently.
False content costs more than ten unpublished drafts, and that is truer than ever now that generative engines repeat what they read.
A serious AI SEO agency tells you who reviews, at which step, and what blocks a publication. If the answer is “AI is very reliable now”, the conversation can end there.
The 5 questions that expose a fake AI SEO agency
- “Show me your engine on your own site.” An agency selling SEO industrialisation must apply it to itself, and be able to show dates, reports, and a history.
- “Who reviews, and what blocks a publication?” The right answer describes a pipeline, with a human in it and written rules.
- “What happens to my site if we stop?” Content, data and access must remain yours. Twelve-month lock-ins with vague reversibility are a signal, not a norm.
- “What does it cost to run, and how do I see it?” AI has crushed production costs: a retainer whose price structure has not moved should explain where the value goes (strategy, review, technical work); we break down the market’s real ranges in our article on SEO agency pricing in 2026.
- “Where does my data go?” Which models, which providers, which policy for sensitive data. An agency that masters its craft has a written answer, per type of data.
What it changes for your company
For a company of 20 to 500 people, the engine mostly changes the rhythm and where the budget goes.
With an engine
The rhythm: small passes every week, so content follows your customers’ real questions
Where the budget goes: what makes the difference, keyword strategy, expert review, technical work, and proof measured in your own Search Console
Without an engine
The rhythm: one big quarterly project, so content follows the agency’s calendar
Where the budget goes: mostly production by the kilo
Visibility in generative engines (being cited by ChatGPT or Perplexity, known as generative engine optimization) runs on the same engine: content structured to be cited serves both.
Four articles in this section go into the work where this engine wins or loses:
- getting cited by ChatGPT: letting AI crawlers read the site, then answering up front with sourced facts;
- the llms.txt file: what it really brings, and what no engine promises;
- hreflang mistakes: a multilingual site announcing pages that do not exist;
- programmatic SEO: generating pages in bulk without falling into the scaled content Google sanctions.
To know where your site stands before committing to an engine, our SEO audit (€1,500 to €3,000 excluding VAT) delivers the diagnosis and the action plan. The SEO and GEO engine then takes over, from €4,500 excluding VAT to set up.
Frequently asked questions
Is an AI SEO agency cheaper than a classic one?
Production costs less, yes. But the price of a retainer depends mostly on scope and review standards. Beware of a very low quote with no review pipeline: you are paying little for content that Google and generative engines are learning to ignore.
Can AI run SEO on its own?
No. It detects, produces and monitors very well. It can neither guarantee a fact nor decide what your business should say. Those last two are precisely what builds long-term visibility. That is why every draft goes through a human reviewer, who checks the facts and decides what gets published.
Does SEO still matter with AI-generated answers?
Yes, twice over: generative engines cite the sources they consider reliable, and those sources are overwhelmingly the ones doing good SEO. The work changes shape, not usefulness. A page that answers a precise question up front, with dated facts, serves both classic rankings and citation by an AI.
How do I check an agency does what it claims?
Ask to see its engine applied to itself, its dated reports, and one example of a draft rejected in review. The rejection is the best proof: a pipeline that never rejects anything does not review. Also ask what happens to your content and your access if you stop: the answer should fit in one sentence.
