Before you start
Things you need to know:
To enable microdata for your Fresh Relevance account, contact your account manager or client support.
For technical reference, see the microdata schema.
How it works
The Product Microdata API (Rich Snippets) is optional, but makes integrations easier. Also, because Google Shopping is now using this structure to identify products in search results it should give you an SEO boost.
Learn more in this Google article.
The Product Microdata API is based around inserting a hidden structure in your HTML.
If you prefer, it can be made visible.
Here's an example showing the data that Fresh Relevance can read from your website:
<div itemscope itemtype="http://schema.org/Product" style="display:none;">
<span itemprop="name">Product Name goes here</span>
<span itemprop="description">Product Description goes here.</span>
<span itemprop="color">purple</span>
<span itemprop="size">M</span>
<div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
<meta itemprop="priceCurrency" content="GBP" />
<span itemprop="price">£28.00</span>
<link itemprop="availability" href="http://schema.org/InStock" />In stock</div>
