title: New to Rich Snippets (html), how do I put them in my code?
body: <p>I've seen the question [How to implement Rich Snippets] but my question is a little more basic (since I'm not the best at HTML).</p>
  
  <p>In <a href="https://developers.google.com/structured-data/rich-snippets/recipes" rel="nofollow">https://developers.google.com/structured-data/rich-snippets/recipes</a> the example code is</p>
  
  <pre><code>&lt;div itemscope itemtype="http://schema.org/Product"&gt;
    &lt;span itemprop="brand"&gt;ACME&lt;/span&gt;
    &lt;span itemprop="name"&gt;Executive Anvil&lt;/span&gt;
    &lt;img itemprop="image" src="anvil_executive.jpg" alt="Executive Anvil logo" /&gt;
    &lt;span itemprop="description"&gt;Sleeker than ACME's Classic Anvil, the
      Executive Anvil is perfect for the business traveler
      looking for something to drop from a height.
    &lt;/span&gt;
    Product #: &lt;span itemprop="mpn"&gt;925872&lt;/span&gt;
    &lt;span itemprop="aggregateRating" itemscope itemtype="http://schema.org/AggregateRating"&gt;
      &lt;span itemprop="ratingValue"&gt;4.4&lt;/span&gt; stars, based on &lt;span itemprop="reviewCount"&gt;89
        &lt;/span&gt; reviews
    &lt;/span&gt;
  
    &lt;span itemprop="offers" itemscope itemtype="http://schema.org/Offer"&gt;
      Regular price: $179.99
      &lt;meta itemprop="priceCurrency" content="USD" /&gt;
      $&lt;span itemprop="price"&gt;119.99&lt;/span&gt;
      (Sale ends &lt;time itemprop="priceValidUntil" datetime="2020-11-05"&gt;
        5 November!&lt;/time&gt;)
      Available from: &lt;span itemprop="seller"&gt;Executive Objects&lt;/span&gt;
      Condition: &lt;link itemprop="itemCondition" href="http://schema.org/UsedCondition"/&gt;Previously owned,
        in excellent condition
      &lt;link itemprop="availability" href="http://schema.org/InStock"/&gt;In stock! Order now!&lt;/span&gt;
    &lt;/span&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I'm wondering, do I just copy and paste this into the HTML on my page? (with my information obviously). Will it mess up my page? Change the formatting? Will anything display on my page? Or will it just act like a comment but search crawlers from google will realize what it is and make use of it.</p>
  
  <p>Also, how long after I add this code to an existing page (that google as already indexed) will the google search results be updated to show the Rich Text Snippet?</p>
  
  <p>Thanks!</p>
