Dan Petrovic (dejan.ai) warns small brands against 'listicle-style' brand association in AI search: every mention of a direct competitor feeds rivals' association signals into LLM training and retrieval data — like link building but linking to all your competitors too.

The article also explains knowledge cutoffs and parametric memory: training data freezes at release, so brands and facts postdating the cutoff exist for models only via live retrieval. That makes crawlable, citable, fresh content critical for AI visibility (AEO) — without it, a brand effectively doesn't exist in the model's memory.
