Product Detail Page (PDP) guidelines
What is a product detail page (PDP)?
A product detail page (PDP) is the page in an online shop that presents a single product: images, price, variants, availability and the button to add it to the cart. It is where most purchase decisions are made.
The guidelines below describe what a good PDP needs, for shoppers, search engines and AI agents.
