Shopify product richsnippet - structured data markup for Shopify product templates

richsnippet.liquid

{% assign current_variant = product.selected_or_first_available_variant %}

<div id="richsnippet">
  <div itemscope itemtype="http://schema.org/Product">
  
    <meta itemprop="url" content="{{ shop.url }}{{ product.url }}">
    <meta itemprop="image" content="{{ product.featured_image.src | img_url: 'grande' }}">  
    <meta itemprop="name" content="{{ product.title | escape }}">  
    <meta itemprop="description" content="{{ product.description | strip_html }}">  
 	{% if product.vendor %}<meta itemprop="brand" content="{{ product.vendor }}">{% endif %}
    
    <div itemprop="offers" itemscope itemtype="http://schema.org/Offer"> 
      <meta itemprop="priceCurrency" content="{{ shop.currency }}">
      <meta itemprop="price" content="{{ current_variant.price | money_without_currency }}">
      <link itemprop="availability" href="http://schema.org/{% if product.available %}InStock{% else %}OutOfStock{% endif %}">
      <meta itemprop="seller" content="{{ shop.domain }}">
      <meta itemprop="itemcondition" itemtype="http://schema.org/OfferItemCondition" content="http://schema.org/NewCondition" /> 
    </div>
    
  </div>

If the price is above 999, it will cause warning on testing tool, so need to add this string filter remove: ","

This line 14 will be:
<meta itemprop="price" content ="{{current_variant.price | money_without_currency | remove: ","}}">

product.first_available_variant and product.selected_or_first_available_variant will return the same for google bot - assign either.

I'd actually use a remove/replace function to format currencies which use a comma if google don't like that.

{{ current_variant.price | money_without_currency | remove: "." | replace: ',', '.' }}

most countries use the decimal - but easy to modify - this is just a guide

one addition is
<meta itemprop="itemcondition" itemtype="http://schema.org/OfferItemCondition" content="http://schema.org/NewCondition" />

I'm still getting warnings for missing SKU

Note the Google prefers JSON and not itemprop
