Summary of L’art de manipuler les IA et empoisonner les LLMs

This video is a detailed conference-style presentation by Allen Cladix, a seasoned SEO and automation expert with over 26 years of experience. It focuses on techniques to manipulate AI systems, especially large language models (LLMs), and influence their outputs through SEO and content strategies. The talk covers practical methods, experiments, and insights into how AI ingests, prioritizes, and reproduces information from the web, and how this can be exploited or optimized for brand visibility, misinformation, or competitive advantage.

Key Technological Concepts and Analysis

Types of AI and SEO Channels

Traditional SEO: Still dominant for transactional queries (e.g., buying products).
Chatbots (Generative AI): Increasingly used for direct answers and summaries, favored for informational queries.
Overview (Aggregators): Used to gather and present information around brands or topics, important for brand reputation management.
Different SEO strategies are needed depending on the channel and user intent (informational, transactional, navigational).

AI Content Influence and Poisoning

AI models scrape and aggregate content from many sources; by flooding the web with targeted content, one can “poison” or manipulate AI outputs.
Example: Spamming a keyword (“Fosine Verneuil”) with hundreds of articles across multiple sites resulted in AI models and search engines prioritizing only those spammed sites.
AI models rely heavily on the majority consensus of sources; flooding with similar content can dominate the narrative.

Effective SEO and Content Techniques for AI Manipulation

Use Exact Match Domains (EMD) to gain trust and priority in AI scraping.
Provide fresh, structured, and factual content with statistics and bullet points to stand out.
Use JSON-LD structured data extensively, including the “sameAs” property to link social profiles and other brand assets, enhancing trust signals.
Prefer content in English, as AI technologies and datasets are predominantly English-based, leading to better indexing and understanding.
Avoid metaphors, feelings, or vague language; AI favors clear, direct, and factual information.

Backlinks and AI

AI uses backlinks primarily to discover content rather than to evaluate authority.
Links from homepage-level sources (e.g., news sites) carry more weight because they are seen as trustworthy starting points.
Reddit is a major source for AI training data and responses, representing about 40% of AI content sources.

Technical Experiments

Testing AI’s ability to read content hidden by CSS (e.g., white-on-white text) or JavaScript-generated content showed AI reads raw HTML content regardless of styling.
AI bots render JavaScript content similar to Chrome/Chromium browsers, so websites must be compatible with these engines for indexing.
Serving different content based on user-agent (cloaking) for AI bots is possible without penalty currently, allowing for “AI-only” content directories.
Dual IP hosting (IPv4 and IPv6) can serve different content to AI scrapers depending on which IP version they use, allowing advanced content manipulation.

Prompt Injection and User-driven AI Manipulation

Embedding prompt injections in URLs or iframes can manipulate AI queries by influencing how AI summarizes or rewrites content.
Using mass user interactions to feed AI with specific prompts can bias AI responses on a large scale.

Content Deletion and GDPR Impact

AI content can be influenced by removing or requesting removal of sensitive or personal data under GDPR.
Deletions can cause temporary disappearance of information from AI models, but reappearance happens after model updates.
Deletions are country-specific, requiring targeted requests per region.

Case Studies and Practical Applications

Multiple examples of manipulating AI knowledge about individuals, brands, and fictional characters were shown.
Speed of influence improved from months to hours using refined techniques.
Use of satellite sites, PBNs (private blog networks), and mass content creation to dominate AI knowledge graphs.
Tool developed (available at hsco.com) to monitor AI content evolution, source impact, and manage content influence.

Product Features and Tools Highlighted

hsco.com Platform A tool to track keywords, analyze AI content sources, monitor evolution of AI responses, and manage influence on AI knowledge bases. It supports API access for integration into other platforms.
Techniques for Cloaking and AI-Only Content Creating dedicated directories or domains serving content only to AI user agents, hidden from normal users, with JavaScript redirects to main pages.
Prompt Injection via URLs and Iframes Using specially crafted GPT chat URLs and invisible iframes to automate prompt injections that bias AI outputs.
IPv4/IPv6 Dual Content Serving Hosting different versions of content on IPv4 and IPv6 to manipulate what AI scrapers see.

Guides and Tutorials Provided

How to Influence AI with Mass Content Spamming

Create clusters of keywords.
Publish hundreds of articles across multiple domains.
Use EMD domains.
Provide structured data and fresh dates.
Leverage social media and Reddit for authority signals.

How to Cloak Content for AI

Detect AI user agents.
Serve AI-specific content in protected directories.
Use JavaScript redirects to funnel human users elsewhere.

How to Use Prompt Injection

Embed prompts in GPT chat URLs.
Use iframes to automate prompt feeding.
Leverage user traffic to amplify prompt injection effects.

How to Delete or Modify AI Content

Use GDPR takedown requests.
Remove or update personal or brand-related data.
Understand geographical scope of deletions.

Best Practices for SEO Content for AI

Use English primarily.
Avoid metaphors and feelings.
Use statistics and bullet points.
Keep content fresh with recent dates in JSON-LD.

Key Warnings and Ethical Notes

The techniques described can be illegal or unethical (black hat SEO, misinformation). It is recommended to use them on disposable or satellite sites, not on main or client sites. Responsibility for misuse lies with the user. AI systems remain vulnerable and can be manipulated easily. The speaker hopes these revelations will push AI developers to improve AI intelligence and resistance to manipulation.
