The verdict in three sentences
Helping customers find fast means selling more: on-site search users convert twice as well as those who browse randomly. Good filters and clear navigation can add up to 15 % in revenue, while a search that returns "no results" drives away 20 % of visitors. Autocomplete, synonyms and merchandising are the decisive weapons.
On-site search: the shortcut to purchase
The search bar is used by the most intent-driven visitors. They know what they want, so give it to them instantly.
| Search feature | Impact (2026 order of magnitude) | Priority |
|---|---|---|
| Instant autocomplete | +2x conversion rate | Critical |
| Synonym handling | -30 % "0 results" | High |
| Typo tolerance | +10 % successful queries | High |
| Live product suggestions | +12 % clicks | Medium |
| Useful "0 results" page | -20 % abandonment | Critical |
| Search in French & common Wolof | + local accessibility | Medium |
A search that forgives typos and understands synonyms ("telephone" = "téléphone" = "smartphone") turns lost queries into sales.
Filters, sorting and navigation: reduce effort
The larger the catalog, the more indispensable filters become. They reduce the visitor's mental effort and speed up the decision.
| Navigation element | Benefit | 2026 best practice |
|---|---|---|
| Price filters (FCFA) | +15 % possible revenue | Slider + clear ranges |
| Availability filter | -abandonment | Hide out-of-stock by default |
| Sorting (price, new, popular) | +comfort | Default = relevance |
| Categories 3 levels max | -confusion | Visible breadcrumb |
| Merchandising (highlighting) | +margin | Sponsored products on top |
| Filters persistent on scroll | +mobile usage | Sticky bar |
On mobile, filters must open in a full-screen panel with a real-time result counter, otherwise they are ignored.
Mini case study
Fatou, who manages an online electronics store in Thiès, had 420 products but no filters and a search with no typo tolerance. 35 % of searches ended in "0 results". Conversion: 1.1 % on 6,000 visits/month = 66 sales at 28,000 FCFA = 1,848,000 FCFA.
After adding search with autocomplete and synonyms, price/brand/availability filters and relevance sorting, "0 results" dropped to 8 % and conversion rose to 1.5 %, i.e. 90 sales = 2,520,000 FCFA/month. A gain of 672,000 FCFA per month.

FAQ
Why is on-site search so important?
Because the visitors who use it have strong purchase intent: they convert about twice as well as average. Neglecting search means losing your best customers.
What should the "no results" page do?
Never leave it empty: offer popular products, nearby categories and a query correction. A raw "0 results" page causes up to 20 % abandonment.
How many filters should I offer?
Enough to cover price, availability and 2-3 key category criteria, no more. Too many filters paralyze; the goal is to reduce effort, not increase it.
Should I handle typos and synonyms?
Yes, it's essential. Tolerating typos and understanding synonyms cuts no-result searches by 30 % and recovers otherwise lost sales.
What is search merchandising?
It's controlling the display order to highlight your high-margin or promoted products. Used well, it raises both sales and profitability.
