If I list a free online product, is there a recommended way to use the phrase βFreeβ when structuring its price, rather than $ 0.00?
schema.org/Offer specification says that the string representation of the price should be of type PriceSpecification , I'm not sure what that means.
Alternative # 1 :
<div itemprop="offers" itemscope itemtype="http://schema.org/Offer"> <span itemprop="price">Free</span> <meta itemprop="priceCurrency" content="USD" /> </div>
Alternative # 2 :
<div itemprop="offers" itemscope itemtype="http://schema.org/Offer"> <span itemprop="description">Free</span> <meta itemprop="price" content="0" /> <meta itemprop="priceCurrency" content="USD" /> </div>
I am leaning towards alternative # 1 (it seems obvious), but I was not lucky to find a link that explicitly states that use.
