Fix collection canonicals and product schema offers

Why this matters

One canonical per collection, and offers that match inventory.

Before you start

• Shopify theme with editable Liquid files
• Product and variant inventory data available in the theme context

How to apply it

1. Audit the current canonical output

   Open theme.liquid and the collection template, then fetch one collection with curl. Count rel=canonical tags and check whether the href is absolute and points at the requested collection.

   Check: curl -s your production domain/collections/<handle> | grep -c 'rel="canonical"' returns exactly 1.

2. Set one canonical per collection

   Keep the theme canonical_url for the base collection and remove app or snippet tags that emit a second value. Point filtered and sorted variants at the base collection unless the view is intentionally indexable.

   Check: The filtered collection URL lists the base collection as canonical and returns 200.

3. Emit Product offers in JSON-LD

   In sections/product-template.liquid or snippets/product-schema.liquid output offers with price, priceCurrency, availability from product.available and an absolute url for the product.

   Check: The Product JSON-LD includes offers.price, offers.priceCurrency and offers.availability.

4. Match availability to inventory

   Map product.available to InStock and OutOfStock, including variant-level availability when the buy box shows a single variant. Update the snippet so every product template inherits it.

   Check: For one in-stock and one sold-out product, JSON availability matches the page button state.

5. Confirm after deploy

   Fetch the collection and product on the live theme, parse the JSON block and compare price and availability with the page. Then check the Product snippets report in Search Console.

   Check: curl -s your production domain/products/<handle> | grep -c 'application/ld+json' is at least 1 and the block parses.
