AI search in 2026: ChatGPT 1.1B MAU and Chinese AI apps 446M as traffic shifts to AI answers. See the landscape and why GEO is the new ticket for brands.
AI search rewrote SEO: zero-click ~60% of searches, AI Overviews cut CTR 34–61%, cited brands gain 35% organic and 91% paid clicks. Get the 2026 playbook.
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.
Build a tagging system in order: unify IDs, layer factual, statistical and model tags with time decay and lifecycle governance, deploy and verify impact.
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.
Conversion rate down: diagnose first - confirm measurement, break down traffic and funnel, check trust and friction, then pinpoint the page and action.
Funnel analysis gives a conclusion, not a chart: where and why drop-off happens. Learn 3 funnel decisions, the drill-down to find loss, and 3 common pitfalls.
Filter bubbles come from a three-way loop, not algorithms alone. Five fixes: hybrid recall, diversity re-ranking, exploration, user control, and monitoring.
A/B test site search changes: split into recall, ranking, and result-page layers; search conversion rate primary, zero-result and first-click rates guardrails.
Collaborative filtering: UserCF for content platforms, ItemCF for stable e-commerce. A 5-dimension comparison, co-occurrence and content-vector blending.
Recommendation ROI comes from scenarios, not one big model. We rank eight high-ROI e-commerce scenarios by rollout difficulty, with data and metrics for each.
Recommendation placement design: pick the page, content, and attention share. Match each slot to page intent and measure cannibalization to confirm real gains.
How to design a membership program? Set the goal first, then structure: points drive behavior, tiers segment users, benefits deliver value, each owning one job.
