Google Shopping and search
Variants that match the colour code and the inch count
Extension and wig search is a specification: 613 lace front wig 24 inch, 1B body wave bundles with closure, glueless bob wig. Shopping matches those queries against the title and the variant attributes, so titles carry colour code and name, length in inches, texture, construction and whether the hair is human or synthetic, in that order. Each colour and length is a separate offer grouped by item_group_id.
Search campaigns follow the same vocabulary. Ad groups by construction and texture, with colour and length as modifiers, and landing pages that show the exact unit. Copy states the two things the shopper is weighing before the click: whether it is human hair and what the delivery time is, because much of the category ships from overseas and the shopper has been burned by long waits.
Two ad-policy points are specific here. Images with heavy text overlays and collage-style photos are common in this category and get disapproved; product images must be clean. And any positioning around medical hair loss, such as wigs for alopecia or chemotherapy, has to avoid targeting people on that basis under Google's personalised advertising rules, even though the product is genuinely helpful for them; the page can speak to it, the audience targeting cannot.
