Traffic: catch the checklist, not the product name
Individual accessory searches are small and heavily contested by marketplaces, so a store built only on product pages fights for scraps. The demand that is winnable is planning demand: what to pack for a long haul flight, what counts as a personal item, which liquids are allowed in cabin baggage, what to take for a first trip with a baby. Those searches arrive before the shopping list exists, which means the store gets to write it. Building genuine checklist and destination content that links to the exact products it mentions turns a category of unsearchable items into a category with a front door, and gives the paid side a landing page worth sending traffic to.
