SEO & LLMs Market: AI poisoning threatens brand reputations in LLM search

Marketers are increasingly focused on how large language models (LLMs) and AI-generated search responses portray brands. The article explains “AI poisoning” — coordinated or bad-faith content (fake reviews, forum posts, sponsored pieces) intended to be ingested by LLMs so those systems later surface negative or misleading responses about a rival. It cites research showing low consumer fact‑checking of AI answers and a Skyword survey finding consumers distrust brands when AI responses conflict with brand claims. Practitioners recommend defensive steps such as improving brand content consistency, publishing product/service guides (which ZeroClick Labs estimates account for up to 28% of AI search citations), and using AI‑search-visibility tools (e.g., Profound, Peec). Some experts remain skeptical about how feasible widespread poisoning is given models’ aggregation of many sources and brands’ existing digital reputations.
