Traffic
Traffic: litres and use case are the two real filters
Search in this category is almost entirely capacity plus purpose. A commuter types a laptop size, a traveller types a litre number with a cabin question attached, a hiker types a day capacity with a trail context, a parent types a year group. Those combinations are what a backpack catalog should be built from, and very few are. Building litre bands and use case collections as real pages, each with copy that explains what that capacity holds and who it suits, captures demand that otherwise goes to marketplaces and to review sites. The same axes then drive the filters, the feed labels and the ad group structure, so one piece of structural work pays into every channel.
