Google Shopping and search
Shopping ads built around the size run
Shopping for sneakers works when each size is its own offer in the feed and the campaign structure separates inline models from launch product. For inline styles we run Performance Max or Standard Shopping by silhouette, with feed rules that pause a variant when its size sells out so budget stops going to a page with a greyed-out button. For launch product we do the opposite: Shopping is switched off until the drop time, because a product that shows in Shopping before it can be bought creates clicks that cannot convert and reviews that mention frustration.
Search ads cover model names, colourway nicknames and the brand plus 'restock'. We add negative keywords for resale terms and for other brands' silhouettes, which otherwise drain budget from anyone with a well-known model name. Price extensions and merchant promotions show the retail price, which matters when the same shoe is listed elsewhere at a markup.
We also watch the counterfeit and misrepresentation side of Google's policies closely. A sneaker brand advertising its own product is fine, but a listing with vague brand fields or missing GTINs can be flagged, and a flagged Merchant Center account during a drop week is expensive.
