What Shopify sites usually get wrong
- Shopify emits Product schema per product, but Organization schema is left to the theme and is frequently missing sameAs.
- robots.txt is editable through robots.txt.liquid since 2021; most stores have never touched it.
- Collection pages rarely answer a question in the first paragraph, so assistants cite the product page or a competitor's guide instead.
