Adding a Stylish Related Posts Accordion in the middle of your Blogger posts is one of the best ways to boost page views, reduce bounce rate, and encourage visitors to explore more of your content. In this step-by-step guide, you will learn how to easily add this feature to your blog.

Today, we will create a Stylish Related Posts Accordion that you can easily add anywhere in the middle of your Blogger posts. This feature is very useful for readers because it automatically displays a list of related articles based on what they are currently reading. By showing relevant posts, it increases the chances that visitors will click on them, explore more content, and stay longer on your blog.

How to Add Related Posts Accordion

Adding a Related Posts Accordion to your Blogger posts is easier than you might think. You don’t need advanced knowledge of HTML, CSS, or JavaScript because the code is already prepared for you. All you need to do is: Implement the required code in the correct place within your Blogger Theme XML. Add the Related Posts Accordion HTML code at the desired position in the middle of your posts. Once set up, this feature will automatically display relevant articles, improving user engagement and encouraging readers to explore more content on your blog.

Important!
Before we start adding any code to your Blogger Theme XML, it is highly recommended to take a backup of your current theme. This way, if anything goes wrong, you can easily restore your theme without losing any of your settings or content.

1. First of all Login to your Blogger Dashboard.
2. On Blogger Dashboard, click Theme.
3. Click the arrow down icon next to 'customize' button.
4. Click Edit HTML, you will be redirected to editing page.
5. Now search the code ]]></b:skin> and paste the following CSS Codes just above to it.

If your Blogger template has a dark mode feature and you want a different color for dark mode, you can customize the CSS as per your needs. Each template may use a different dark mode class, so make sure to replace the marked class with the correct dark mode class of your template.

  <script>
    var labelArray = [<b:if cond='data:post.labels'><b:loop values='data:post.labels' var='label'>&quot;<data:label.name/>&quot;<b:if cond='data:label.isLast != &quot;true&quot;'>,</b:if></b:loop></b:if>];
    var autoRelatedConfig = {

      numPosts: 10,
      titleLength:&quot;auto&quot;,
      newTabLink: false,
      callBack:function(){}
    }
  </script>
  <script>/*<![CDATA[*/ var autoRelatedIndex,showAutoRelated;null!=document.getElementById("autoRelatedPost")&&function(a,n){var e,u={homePage:"https://blog.fineshop.eu.org",numPosts:7,titleLength:"auto",containerId:"autoRelatedPost",newTabLink:!1,callBack:function(){}};for(e in autoRelatedConfig)u[e]=("undefined"==autoRelatedConfig[e]?u:autoRelatedConfig)[e];function l(e){var t=a.createElement("script");t.async="async",t.rel="preload",t.src=e,n.appendChild(t)}function c(e){var t,a,n=e.length;if(0===n)return!1;for(;--n;)t=Math.floor(Math.random()*(n+1)),a=e[n],e[n]=e[t],e[t]=a;return e}var o="object"==typeof labelArray&&0<labelArray.length?"/-/"+c(labelArray)[0]:"";autoRelatedIndex=function(e){var t=e.feed.openSearch$totalResults.$t-u.numPosts,e=(e=1,t=0<t?t:1,Math.floor(Math.random()*(t-e+1))+e);l(u.homePage.replace(/\/$/,"")+"/feeds/posts/summary"+o+"?alt=json-in-script&orderby=updated&start-index="+e+"&max-results="+u.numPosts+"&callback=showAutoRelated")},showAutoRelated=function(e){var t,a,n=document.getElementById(u.containerId),l=c(e.feed.entry),o="<ul>",r=u.newTabLink?' target="_blank"':"";if(n){for(var s=0;s<u.numPosts&&s!=l.length;s++){a=l[s].title.$t,a="auto"!==u.titleLength&&u.titleLength<a.length?a.substring(0,u.titleLength)+"&hellip;":a;for(var d=0,i=l[s].link.length;d<i;d++)t="alternate"==l[s].link[d].rel?l[s].link[d].href:"#";o+='<li><a href="'+t+'" '+r+"><span>"+a+"</span></a></li>"}n.innerHTML=o+="</ul>",u.callBack()}},l(u.homePage.replace(/\/$/,"")+"/feeds/posts/summary"+o+"?alt=json-in-script&orderby=updated&max-results=0&callback=autoRelatedIndex")}((window,document),document.getElementsByTagName("head")[0]); /*]]>*/</script>
