Google does not penalize AI use, but scaling low-value AI content triggers spam policy. Learn disclosure templates, IPTC metadata, and a 3-red-line self-check.
Mobile search is shaped by screen, input cost and network. Compare in-app vs H5 retrieval and use our KPI baseline to tune entry, autocomplete and zero results.
How to do search query analysis: turn query logs into a zero-cost demand sample via termization, zero-result governance, rewrite attribution, and a closed loop.
Vector search in production: map queries and docs into a semantic space, replace brute-force with ANN, pick HNSW or IVF+PQ with hybrid retrieval plus reranking.
Site search UX optimization links autocomplete, correction, synonyms, faceted filters and zero-result recovery as one loop via latency and zero-result rate.
Search ROI is hard to measure: a three-layer usage-quality-revenue measurement, contribution vs incremental conversion, an ROI formula, and four misjudgments.
Enterprise knowledge base search fails when documents scatter and permissions differ. Rollout: ingestion, permission alignment, metadata, ranking, governance.

Recommendation systems need core metrics: CTR for appeal, CVR for value, diversity and novelty vs drift, coverage for long-tail; offline iterates, online A/B.
