Paid Placements in GEO: Where Does Legitimacy End?

A Tuesday morning, a call that wakes you up

A client calls me on a Tuesday morning. He received a proposal by email. Subject line: ‘Dominate Google’s AI responses’. The pitch? €2,500 per month. Guaranteed placement in ChatGPT, Perplexity, Gemini. Guaranteed. The kind of thing that makes an e-commerce owner’s head spin.

I listen. He reads me the email. I recognize the vocabulary. ‘Visibility boost’, ‘native integration’, ‘network of authoritative sites’. This isn’t my first time seeing this. Since I moved to Southeast Asia in April 2025, I audit even more sites remotely. And the phenomenon is accelerating.

In 2026, GEO — Generative Engine Optimization — is drawing attention. Optimization for AI answer engines is a powerful lever. But some are turning it into a minefield. The boundary between legitimate SEO and manipulation is blurring.

My client was hesitant. He smelled trouble. He was right to call.

« I’m not selling you the method. I’m showing you the pages. »

That’s what I did. In 37 minutes of live audit, we picked apart the offer. We found a dangerous shortcut, not a GEO strategy.

Cette statistique de Search Engine Land illustre l’ampleur du problème : quand une IA référence une marque, ce n’est souvent pas le site qui a payé pour la mention.

When GEO tips over: the red line of paid placements

On June 26, 2026, Search Engine Land published an article that made waves: ‘The paid brand mention problem in GEO’. It describes a drift. Agencies pay third-party sites to mention a brand. The goal: have LLMs absorb these mentions and return them as recommendations. SEO disguised as PR.

I observe the same phenomenon. Out of 15 audits I run each week, 6 to 7 e-commerce businesses have encountered these offers. The pitch is polished: ‘We place you in in-depth articles, listicles, influential forums. The AIs scan them. Your brand rises.’

Except Google is refining its models. The study cited by Search Engine Land shows it: 69% of the time, Google AI Overviews cite a competitor rather than the site referenced in these paid content pieces. Why? Because LLMs detect manipulation patterns. Forced citations. Artificial contexts.

The red line is clear: a placement is legitimate if it stems from authentic editorial recommendation. It becomes manipulative when it’s bought in bulk, without relevance, across networks of sites created for that purpose.

I often tell my clients: one earned mention beats ten bought mentions.

The 3 promises that should alert you immediately

I’m not a fortune teller. But after 30 years of SEO and 1,300 semantic silos delivered, I recognize a trap pitch in three sentences.

• 1. ‘Guaranteed placement in AI results.’ No serious pro guarantees placement in an LLM. Models are probabilistic, not deterministic. This kind of promise rests on temporary biases or loopholes. Google closes them. Fast.
• 2. ‘Network of 200 high-authority sites.’ Look at the domains. They’re often expired blogs, bought back, inflated with link building. The apparent authority is window dressing. In 2026, these networks are prime targets for Spam Updates. The June 2026 one hit hard.
• 3. ‘No impact on your classic SEO.’ False. An undeclared paid link scheme contaminates your backlink profile. Even if the goal is GEO, Google processes signals in a cross-cutting way. I once saw a client lose 37% of their organic traffic in 4 months because of links bought for GEO. Their profile was devalued.

These promises play on urgency and fear of missing the AI train. My advice: if it looks like a miracle solution, it’s hiding a powder keg.

A textbook case: 37% traffic lost in 4 months

Let me tell you about an e-commerce business I work with. Catalog of 3,200 items. 45,000 organic sessions per month. Clean site, well-architected. In January 2026, a GEO agency contacts them. Tempting proposal: €3,800 per month to be cited in ‘the AI answers that matter’.

They sign. Six months. €22,800 invested.

During the first few weeks, some mentions appear. Listicles, comparisons, forums. Their ego soars. Then, on June 24, 2026, Google rolls out its June Spam Update. In four days, 14 of their key pages drop 2 to 3 positions. Organic traffic plummets. 37% of sessions lost in 4 months. Paid acquisition barely compensates.

I analyze their backlink profile. 47 new domains point to them. Barely disguised PBNs. Zero-traffic sites. Over-optimized anchors. The pattern is clear: the GEO agency bought links in bulk to force mentions. Google detected the scheme.

The problem wasn’t GEO. It was the method. It took us 5 months to clean up the profile. 5 months of disavowals, reworked content, trust signals to rebuild. Total cost: 3.2 times the initial budget.

Optimize for AIs without cheating: what I apply with my clients

Legitimate GEO exists. It rests on a reality few agencies explain: LLMs aggregate sources with authority on a topic. To be cited, you must become that source.

I apply a three-layer approach.

• 1. Solid semantic architecture. An e-commerce site must be structured by entities, not just keywords. Every product, every category must be tied to a clear concept. I use the DOSE framework (designed by Guillaume Attias at BMO Academy) to forge this backbone. AIs instantly understand what the site is about.
• 2. Content that answers implicit questions. LLMs seek complete answers, not optimized pages. With an appliances client, we created 32 usage guides, 47 compatibility sheets, 18 sourced comparisons. No paid links. Result: 820% increase in mentions on Perplexity in 6 months. Because the content was the best answer available.
• 3. External trust signals naturally earned. Authentic press citations, verified reviews, transparent editorial partnerships. Nothing paid. Just solid groundwork. I’ve seen a site go from 0 to 23 AI mentions in 5 months, simply because independent experts mentioned it spontaneously.

This approach takes more time. 6 to 9 months. But it’s sustainable. Zero penalties. Zero collateral damage.

The framework that holds up: beyond keywords

Many e-commerce owners ask me how to exist in ChatGPT or Gemini. I show them a concrete case.

A supplement site. 600 products. 12,000 organic sessions per month. Zero AI mentions. I applied a simple process:

• Semantic mapping: identify the 28 main entities around supplements (deficiencies, active ingredients, health benefits, interactions). Each page was anchored to an entity.
• Internal linking: 347 contextual links added between semantically related pages. Each link strengthens an entity relationship.
• Product sheet rewriting: more than technical descriptions — answers to the ‘why’ and ‘how’ that users type into conversational interfaces.
• Enriched Schema.org tags: FAQ, HowTo, Product with entity attributes. AIs love that.

Result in 7 months: +620% increase in mentions in generative AI responses. 47 informational queries where the site appears as a reference. No paid links. No bogus promises.

GEO is like SEO 20 years ago. Cheaters get ahead at first. Then algos mature. Don’t play the sprint. Play the marathon.

Your brand in LLMs: an asset you build

I look at Search Engine Land data and compare it with what I observe on the ground. I see a trend: LLMs are becoming recommendation engines, not just search engines. They cite brands they judge relevant, trustworthy, consistent.

So how do you build that image?

First, by recognizing that GEO isn’t an independent channel. It’s an extension of SEO, branding, user expérience. Every mishandled negative customer review, every weak product sheet, reduces your chances of being cited.

Next, by building authentic press relationships. Not sponsored articles. Expert contributions. Original research. I saw a travel client multiply their AI citations by 14 by publishing an exclusive survey on 2026 trends. Free.

Finally, by tracking mentions. Tools exist to follow your brand in ChatGPT, Perplexity, Gemini. I recommend checking weekly. What isn’t measured doesn’t improve.

One thing’s certain: questionable paid placements will collapse. Google and other LLM providers have entire teams dedicated to detecting manipulation. The June 2026 Spam Update proved it. Shortcuts don’t work anymore.

I build systems that run without me. That means solid semantic architectures, quality content, natural links. Nothing magical. Just clean work. And it pays.
