About ThirdLove
Founded 2013 · US
Heidi Zak and Dave Spector founded ThirdLove with a half-cup-size patent — moving the category from standard A/B/C/D-only sizing into 80+ sizes. The brand's fit-finder quiz captured millions of sizing data points and effectively crowd-sourced category R&D. Famous for the open-letter ad criticising Victoria's Secret in 2018 that became a viral marketing case study.

Notable for the schema.org audit
ThirdLove's storefront is unusually data-rich because the fit-finder quiz drives most of the customer journey. The Schema + apps reflect that quiz-driven conversion architecture.

What this Schema grade reveals
D-grade signals meaningful structural gaps in ThirdLove's storefront Schema. The most common pattern at this grade band is missing Product schema fields (offers price + currency + availability), conflicting Review schema from two apps (Loox + Judge.me both writing AggregateRating), or no BreadcrumbList — fixable in an hour of theme.liquid work.
Breakdown: 1 PDP finding. The live tool ships a copy-paste-ready Liquid snippet for each finding — every finding is fixable in theme.liquid without installing additional apps.
Cross-check with the App Stack Detector to see which Schema-emitting apps are installed — most Schema problems on Plus tenants come from conflicting Review schema between Loox + Judge.me + the theme rather than missing apps.
