Customer language
Link alternative product names and professional terms only where catalog context supports that.
Synonyms →Zero-result searches
Make empty results a targeted improvement cycle.
A no-result can indicate customer language, spelling, missing product data, wrong indexing, or simply a product you don’t sell. The right solution starts with the cause.
Cause first
Do not treat every no-result the same.
Spelling
Fix clear typing errors without damaging strong exact matches.
Search Quality →Product data
Check titles, attributes, categories, and indexability when products do exist.
Product data →Semantic fallback
Use meaning as an additional signal when literal matching is lacking.
FallbacksPrioritizing
Solve the zero-result searches that have a real impact first.
Volume
Start with recurring search queries instead of loose incidents.
Zero-result searches analytics →Commercial relevance
Combine volume with product and conversion context.
Conversion →Recovery
Only show alternatives that demonstrably match the intention.
Zero-result searches UX →Regression
Add resolved critical queries to your fixed test set.
Regression tests →Use your real no-result list as a starting point.
This way you make visible which improvements should come from language, data, assortment or search logic.
