There are a<br \/>\n  few things you need to look out for when using JavaScript to generate structured data on your<br \/>\n  websites, and this guide covers best practices and implementation strategies. If you&#8217;re new to<br \/>\n  structured data, you can learn more about<br \/>\n  <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/structured-data-intro\/\">how structured data works<\/a>.\n<\/p>\n<p>There are different ways to generate structured data with JavaScript, but the most common are:<\/p>\n<ul>\n<li><a href=\"#use-google-tag-manager\">Google Tag Manager<\/a><\/li>\n<li><a href=\"#custom-javascript\">Custom JavaScript<\/a><\/li>\n<\/ul>\n<aside class=\"key-point\"><b>Using <code>Product<\/code> markup?<\/b> Be aware that dynamically-generated<br \/>\n  markup can make Shopping crawls less frequent and less reliable, which can be an issue for<br \/>\n  fast-changing content like product availability and price. If you&#8217;re a merchant optimizing for<br \/>\n  all types of shopping results, make sure your server has enough computing resources to handle<br \/>\n  increased traffic from Google.<br \/>\n<\/aside>\n<h2 id=\"use-google-tag-manager\" tabindex=\"-1\">Use Google Tag Manager to generate JSON-LD dynamically<\/h2>\n<p><a href=\"https:\/\/tagmanager.google.com\/\" class=\"external-link\">Google Tag Manager<\/a> is a<br \/>\n  platform that lets you manage tags on your website without editing the code. To generate structured<br \/>\n  data with Google Tag Manager, follow these steps:\n<\/p>\n<ol>\n<li><a href=\"https:\/\/support.google.com\/tagmanager\/answer\/6103696\" class=\"external-link\">Set up and install Google Tag Manager<\/a> on your site.<\/li>\n<li>Add a new <b>Custom HTML<\/b> tag to the container.<\/li>\n<li>Paste a <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/structured-data-types\/\">supported structured data<\/a> block into the tag content.<\/li>\n<li>Install the container as shown in the <b>Install Google Tag Manager<\/b> section of your container&#8217;s admin menu.<\/li>\n<li>To add the tag to your website, publish your container in the Google Tag Manager interface.<\/li>\n<li><a href=\"#testing\">Test your implementation<\/a>.<\/li>\n<\/ol>\n<h3 id=\"using-variables-in-google-tag-manager\" tabindex=\"-1\">Using variables in Google Tag Manager<\/h3>\n<p>Google Tag Manager (GTM) supports <a href=\"https:\/\/support.google.com\/tagmanager\/topic\/7683268?ref_topic=3441647\" class=\"external-link\">variables<\/a><br \/>\n  to use information on the page as part of your structured data. Use variables to extract<br \/>\n  the structured data from the page instead of duplicating the information in GTM. Duplicating the information in GTM increases<br \/>\n  the risk of having a mismatch between page content and the structured data inserted using GTM.\n<\/p>\n<p>For example, you can dynamically create<br \/>\n  a <a href=\"https:\/\/alienroad.com\/google-bilgi-bankasi\/recipe-recipe-howto-itemlist-structured-data\/\">Recipe<\/a> JSON-LD block<br \/>\n  that uses the page title as the recipe name by creating the following custom variable named<br \/>\n  <code>recipe_name<\/code>:\n<\/p>\n<div><\/div>\n<p>You can then use <code>&#123;&#123;recipe_name&#125;&#125;<\/code> in your custom tag HTML.<\/p>\n<p>We recommend to create variables to collect all the necessary information from the page using variables.<\/p>\n<p>Here is an example for the custom HTML tag content:<\/p>\n<div><\/div>\n<aside class=\"key-point\"><b>Note:<\/b> The previous sample assumes that you defined the variables <code>recipe_name<\/code>, <code>recipe_image<\/code> and <code>recipe_author<\/code> in GTM.<\/aside>\n<h2 id=\"custom-javascript\" tabindex=\"-1\">Generate structured data with custom JavaScript<\/h2>\n<p>Another way you can generate structured data is by using JavaScript to either generate all of<br \/>\n  your structured data or add more information to the server-side rendered structured data. Either way,<br \/>\n  Google Search can understand and process structured data that&#8217;s available in the DOM when it<br \/>\n  renders the page.
