Visitors search differently than you do
“blue chair,” “dining table,” “something for a small living room.” Sero Search understands compound words, inflections, and typos — and answers the rest with AI.
Search your customers understand. And that tells you what to do.
One script tag on your online store. Visitors get results as they type, ask questions in plain language, and you see exactly where search breaks down, with a button beside it to fix the issue.
More than 500 brands already trust Sero in retail, travel, beauty, and more
The search bar is the most expensive place to lose a customer
People who search want to buy. But shoppers type in everyday language, not product names—and most search functions return nothing useful. Sero Search solves that in three places.
Questions aren’t search queries
“Will this table fit in 2.5 meters?” isn’t a filter. The assistant in the widget answers based on your own product data and customer service pages, with source citations.
You don’t know what you’re missing
Every search query with no results is a customer who leaves. You’ll see them on your dashboard, with one button to turn one into a synonym or rule.
Results as you type, with Dutch language logic
No AI needed for what should simply work. The index lives in memory and corrects, inflects, and splits words the way Dutch shoppers type them.

Results as you type, with Dutch language logic
No AI needed for what should simply work. The index lives in memory and corrects, inflects, and splits words the way Dutch shoppers type them.
- “Chair” also finds dining chairs, and compound words are recognized
- “Blue chair” and “chair blue” return the same results
- Typos are corrected (“dining table,” “armchair,” “coffee table”)
- Color, size, and material are searchable and filterable
- Configure facets, sorting, and price formatting yourself
Larry
A colleague who knows your search function
Larry lives in the dashboard, reads your own data, and tests real search queries before making any claims. He never changes anything behind the scenes: he suggests changes, you approve them.
- Follows along with the page you’re on
- Shows which data it used for each answer
- Suggests synonyms, merchandising rules, and settings
- Read-only; writing happens with your approval
Insights
Every failed search is a to-do list
Search volume, click-through rate, AI usage, and zero-results over 7, 30, or 90 days, with the previous period alongside it. Next to every term that returned nothing is a button to turn it into a synonym.
- Top search terms with average result counts
- Most-clicked products, by name and SKU
- Search queries with no results, sorted by lost revenue
- Recent searches with source: instant, AI, or answer
Take control
You decide what appears at the top
For each search term, pin products, boost them, hide items, or send visitors straight to a page. Exact, “starts with,” or “contains”—the most specific rule wins.
- Synonym groups, added manually or suggested by AI
- Suggestions come only from your catalog and brand identity, never from search logs
- Push words per product: make an item appear for a term that isn’t in its product data
- Ranking weights for title, brand, category, popularity, and inventory
Widget
Looks like you built it yourself
Enter your website address; Sero pulls colors, visual language, fonts, and tone of voice from your own site. Then choose how the widget appears: as a button, replacing your existing search bar, or as a popover.
- Live preview in a demo store styled with your brand
- Price formatting down to the cent: € 1,499.00 or 1499,- you choose
- Configurable starting view: popular, new, or discounted
- Adjust the width, position, and copy yourself
Catalog
Your feed, without the hassle
XML, CSV, or JSON, via a URL or upload. A mapping agent identifies the fields, merges variants, and keeps the index up to date: only changed products are reprocessed.
- Incremental sync based on a content fingerprint
- Exclude products individually or in bulk
- Rules for out-of-stock products
- Filters, list view, and a detail panel with all fields
API
The same API style as the rest of the Sero stack
Deterministic REST for exact read and write actions, plus one conversational endpoint that answers questions about your search data. Set up identically to Sero CDP and Sero ProductShot.
- API keys with scopes per component, isolated by workspace
- In-app documentation, plus a ready-to-use skill for Claude Code
- Playground to try a key instantly
- Idempotency keys, rate limits, and cursor pagination by default
