Name the material. Show where it comes from. Make the ingredient the hero, not the product.
Broken down by Jonas, a former Meta growth lead, from Allbirds's live ads in the Meta Ad LibraryAllbirds doesn't sell shoes, they sell 'shoes made from merino wool' and 'shoes made from eucalyptus tree fiber.' The material origin IS the brand story. This works because sustainability-minded consumers want to know what they're buying, not just what it looks like. The material creates differentiation in a market where most shoes are made from anonymous synthetic blends. By naming the material, Allbirds gives the buyer a story to tell: 'These are made from trees.' That story does word-of-mouth marketing every time someone asks 'nice shoes, what are those?'
Material storytelling works for any product where the ingredient matters, food (single-origin coffee, grass-fed meat), skincare (specific active ingredients), furniture (solid wood vs. MDF), clothing (specific fabrics). The key: the material must genuinely be better AND the audience must care about the difference. If your customers buy on price alone, material stories won't move them. If they buy on quality or values, the material is your strongest differentiator.
This breakdown is built from Allbirds's active ads, running for 5+ weeks at the time of writing, a signal the format is still working. See the current set for yourself in Meta's public Ad Library.
