Site search does not think. It obeys. And most of what it obeys was written by someone who has long since forgotten writing it.
A homeware retailer I know found this out last week. A shopper typed “autumn wreath” into the search bar. The site answered with 970 results and a front row of Christmas wreaths, three months early, like a relative who turns up to Sunday lunch already dressed as Santa.
Nobody had broken anything. That was the problem.
Here is what was actually going on. Inside the search app sat a keyword group for Christmas wreaths. At some point six autumn phrases had been added to it as exact matches. Autumn wreath. Autumn wreaths. Fall wreath. Pumpkin wreath. Sunflower wreath. Woodland wreath. The group came with its own featured list, Christmas first. So every autumn search walked politely into the grotto.
The fix took one afternoon and built nothing. Six keywords removed, saved. The same search now returns 178 results, the first nine are all autumn wreaths, and there is not a Christmas wreath in the first sixteen.
This is the part most teams miss. The person typing into your search bar is the most decided visitor you will get all day. They have told you, in their own words, exactly what they want. Ads guess. Collection pages guess. Search is the one place the customer hands you the answer, and then an old instruction quietly overrules them.
Site search is not a feature you switch on once. It is a drawer of old sticky notes, and somebody has to open it before the season changes.
