What is Search by Tag?
Search by tag retrieves items labeled with editorial or system tags (e.g., sustainable, giftable, back-to-school). Tags act as boolean facets that cut across categories and seasons.
How It Works (quick)
- Tagging sources: Manual curation, rule-based tagging (attributes/metadata), or ML (phrase/entity extraction).
- Indexing: Store tags in a keyword/boolean field for fast filtering and aggregations.
- Querying:
tag:vegan or UI chips; combine with other facets (price, size). - Governance: Tag dictionary with definitions, owners, and expiries; audit logs.
Why It Matters in E-commerce
- Merchandising agility: Launch collections and campaigns without taxonomy changes.
- Findability: Shoppers discover missions (e.g., “carry-on friendly”, “winter commute”).
- SEO: Stable, curated collection pages built on tags can rank and convert.
Best Practices
- Controlled vocabulary: Short, human names + stable IDs; avoid synonyms explosion.
- Quality gates: Minimum coverage and precision before exposing a tag.
- Expiry & seasonality: Auto-sunset outdated tags; review quarterly.
- Transparency: Explain tags on PLP (tooltip or glossary link).
- Analytics: Track tag usage, CTR, conversion, and assisted revenue.
Summary
Search by tag turns curated labels into fast, cross-category filters and collections. Govern the vocabulary, index as booleans, and review seasonally.
