Spur found a search engine serving cleaning kits when customers looked for gaming consoles

Someone searching "gaming console" on a tech marketplace was getting accessories, like a cleaning kit, instead of actual consoles. The AI search wasn't matching intent, just keywords, and sending buyers down a dead end.

What this

one catch saved.

10hrs

Dev time saved

Shipped, this needs someone to dig into the search ranking logic, figure out why accessories are surfacing above consoles for that query, and test the fix across enough search terms to be confident it won't break other results.

$80K+

Lost potential revenue

Every session that hits a broken search result on a high-intent query is a lost sale on one of the highest-ticket items in the catalogue.

4hrs

Manual QA time

Catching this manually means searching across a range of product categories and reading the results carefully enough to notice when the intent doesn't match, easy to miss if you're only spot-checking a few queries.
