Search quality degradation

Search quality degradation is the decline in the relevance, accuracy, or usefulness of search engine results over time, driven by the adversarial adaptation of content producers to ranking algorithms. It is a form of adversarial adaptation in which SEO-optimized content, AI-generated text, and platform-gamed media progressively displace the high-signal content that the ranking algorithm was designed to surface. The degradation is not merely an accumulation of spam; it is a structural shift in the information ecosystem, where the feedback loop between query and result becomes increasingly self-referential. The search engine optimizes for engagement; content producers optimize for the search engine; users receive content optimized for optimization. The original signal — human intent — is progressively lost.
