Query intent matters more than query text — same query means different things in different contexts
Recall (did we find it?) vs precision (is it right?) — trade-off always
Personalisation compounds — the longer a user uses, the better it should feel
Freshness matters — stale results kill trust
Zero-result pages are critical UX — don't just show 'no results'
5 Types of Discovery
Search (user-initiated)
User knows what they want; deliver it fast
Browse (category-based)
User exploring within structure; help them navigate
Feed / recommendations
Algorithm chooses what to show; bears responsibility for quality
Collections / curated
Human curation; brand voice and editorial quality

FAQ
Is search PM a specialised role?
At companies with complex catalogs (e-commerce, content platforms, marketplaces), yes. Search PMs work closely with ML engineers, relevance teams, and data scientists. Skills: query understanding, ranking, personalisation, evaluation methods. It's a specialist role that pays well and has deep career paths.
What's the biggest search PM mistake?
Over-indexing on one metric like click-through rate. High CTR can mean shallow engagement or clickbait. The PMs who build sustainable search products measure downstream metrics: did the user find what they wanted? Did they return? Short-term CTR optimisation can hurt long-term trust.
