Structured data markup matches visible page content

Structured data that contradicts visible page content is treated as deceptive markup under Google's Structured Data Policies, and offending pages lose rich result eligibility or get manual actions applied. When an Article's JSON-LD headline is hardcoded while the H1 renders from post.title, every new post ships a schema lie. Findability collapses for the affected templates because rich snippets disappear and crawlers downrank the URL.

Populate JSON-LD from the same variables that render the visible DOM. In app/products/[slug]/page.tsx, bind name and description to the product object you already fetched for the template, and never hand-write static strings in a dynamic context.

const product = await getProduct(slug)
const schema = { '@type': 'Product', name: product.name, description: product.description }
