How it Works – Schema.org Schema.org metadata describes ‘things’ on the web as agreed upon by the major search engines to improve search & discoverability


Recipe Metadata Example

<div itemscope itemtype="http://schema.org/Recipe"> <div itemprop="nutrition” itemscope itemtype="http://schema.org/NutritionInformation"> Nutrition facts: <span itemprop="calories">240 calories</span>, </div> Ingredients: - <span itemprop="ingredients">3 or 4 ripe bananas, smashed</span> - <span itemprop="ingredients">1 egg</span>
