An apparel or footwear catalogue is where most Columbus marketplace accounts break, and it breaks in the same place every time: parentage. Colours listed as standalone products, sizes split across three unrelated ASINs, a discontinued colourway still holding the reviews. Every one of those is a listing that never accumulates the review volume or rank it earned, and no amount of bid work fixes it. So the first pass is structural — variation families rebuilt around the way the product is actually bought, backend search terms populated with the words shoppers type rather than the words on your line sheet, size chart data attached properly, and suppressed or stranded items traced to a cause instead of resubmitted and hoped over.
Then the economics, which in this city are unusually product-dependent. A t-shirt and a squat rack cannot be managed by the same rule. Amazon's size tiers and storage charges punish anything bulky and slow-moving, so a strength or home-gym catalogue usually splits: small accessories into FBA, freight-class items on FBM against your own carrier rates. Fragrance, candles and anything alcohol-based drops into dangerous-goods review, which is a documentation problem that stalls launches for weeks if it is discovered after the listing goes live rather than before. Apparel carries the other tax — marketplace return rates on fit-driven product are high, returns are graded and often not resellable, and an ACoS that looked fine before returns can be negative contribution after them. We model contribution per unit after referral fee, fulfilment, storage and expected returns, then set advertising targets against that number.
Advertising and channel strategy come last, and they come with a boundary. Sponsored Products, Brands and Display get built by intent and margin band, converting search terms promoted to exact match, negatives maintained weekly. Walmart Marketplace is worth opening where the category and price point fit its buyer, TikTok Shop where the product demonstrates on video and the margin can carry a creator commission on top of the platform fee, and Faire where you already have a wholesale side and want buyers finding you without a rep. But the point of all of it is discovery. The second purchase, the bundle, the refill and the subscription belong on your Shopify store, and we build the permitted routes there — package inserts, Brand Registry follow-up tools, marketplace-exclusive pack sizes that do not undercut your own site — rather than pretending we can lift buyer emails off a platform that does not give them out.
