How to Add and Display Twitter Cards for Your Blogger Blog
Tired of sending plain, forgettable text links when you share your Blogger posts on Twitter? Twitter Cards turn those basic tweets into polished, clickable rich previews that grab attention and boost engagement. Launched by Twitter in 2012, these previews work similarly to Google’s rich snippets (powered by Schema markup) and Facebook’s Open Graph tags — but while WordPress users can add them with a single plugin, Blogger users just need a quick edit to their theme HTML. Today, we’ll walk you through every step to set up Twitter Cards for your Blogger site. What Are Twitter Cards, and Why Do They Matter?
Twitter Cards are snippets of code added to your blog’s HTML that tell Twitter how to display links to your posts in timelines. Unlike most social platforms that rely on Open Graph meta tags, Twitter has its own dedicated tag set, though many elements overlap. A well-made Twitter card will show your post’s title, a short descriptive blurb, a thumbnail or full-width hero image, and your site’s (or author’s) Twitter handle. Nearly 90% of active WordPress blogs use plugins to automatically add Twitter Cards, but Blogger requires a quick manual code tweak — which is why so many Blogger site owners skip this easy optimization. Even a basic setup will make your shared posts look far more professional and drive more clicks to your content. The Right Twitter Card Types for Blogger Blogs
Twitter offers 7 total card types, but most personal Blogger blogs only need two: 1. Summary Card
The default, no-frills Twitter card. It displays a small thumbnail image next to your post title, short description, and linked handles. This is perfect for text-heavy posts like tutorials, opinion pieces, or how-to guides. 2. Summary Large Image Card
This upgraded version swaps the small thumbnail for a full-width hero image at the top of the preview, followed by your post title and description. It’s ideal for visual blogs like food, travel, fashion, or photography, where your featured image is the main draw. The other five card types (Photo, Gallery, App, Player, and Product) are designed for specific use cases like sharing single photos, mobile app downloads, or product listings — most personal Blogger blogs won’t need these. Custom Twitter Card Code Snippets for Blogger
We’ll use Blogger’s built-in XML tags and conditional tags to create code that only loads Twitter Cards on individual post pages, not your homepage, archive pages, or search results. We’ll also add fallbacks for missing meta descriptions and featured images to avoid broken previews. First, pick one of the two snippets below, then edit the placeholder Twitter handles to match your own: Basic Summary Card Snippet
This code will load the standard summary card for all your individual posts: Replace `@YOURBLOGHANDLE` with your blog’s official Twitter account, and `@YOURAUTHORHANDLE` with your personal author handle (you can use the same handle for both if you don’t have separate accounts). This code will automatically use your post’s custom meta description if you’ve filled one out, or pull a short snippet from the start of your post if you haven’t. Large Image Summary Card Snippet
This code swaps the thumbnail for a full-width hero image, and works only on individual post pages: This code includes standard image dimensions (1200x628 pixels) for sharp, full-width previews, and falls back to your blog’s favicon if you don’t set a featured image for a post. Adjust the width and height values if you want to use custom image sizes. How to Install the Code on Your Blogger Theme
1. Log into your Blogger dashboard and navigate to **Theme > Edit HTML**. 2. Use your browser’s find tool (Ctrl+F or Cmd+F on Mac) to locate the opening `` tag. 3. Paste your chosen code snippet directly below the `` tag, or right after any existing meta tags you’ve already added to your theme. 4. Click **Save Theme** to apply your changes. Validate Your Twitter Cards
Once you’ve installed the code, use Twitter’s official Card Validator tool to test your setup. Simply paste the URL of a single blog post into the tool and click **Preview Card** to see exactly how your tweet will look. The tool will also flag any errors, like missing images or invalid meta tags. A few pro tips to get the best results: - Always fill out custom post meta descriptions to avoid truncated, messy snippets pulled from your post text. - For large image cards, use high-quality featured images at least 1200x628 pixels to ensure they look sharp on all devices. - Double-check that your Twitter handles are entered correctly, including the `@` symbol. You no longer need to register your site with Twitter to use Twitter Cards — the validator tool will work for any site with properly implemented code. Source
