Search and Merchandising in E-commerce
Site search is one of the highest-value interactions on an e-commerce site — users who search have high purchase intent and expect accurate, fast results. Effective merchandising uses search results ranking to promote relevant products, surface new arrivals, and manage inventory. Together, search and merchandising directly impact conversion rates and revenue.
The Limits of Default Platform Search
Default search in most e-commerce platforms is keyword-matching with limited relevance tuning. Deficiencies: poor handling of synonyms and misspellings, no understanding of user intent, no merchandising controls, slow performance with large catalogues, and limited analytics. For significant catalogues or high search volumes, specialist search solutions outperform native search materially.

Merchandising Best Practices
- Boost in-stock products and suppress out-of-stock automatically
- Rule-based boosting for promoted products, new arrivals, high-margin items
- Synonym management — map "trainers" to "sneakers," brand aliases, common misspellings
- Analytics — monitor zero-result searches, low-click results, and exit-after-search rates
