### Why Only the URL Shows
When you share a link from your Blogger blog on Facebook and only the URL appears, it’s likely because Facebook can’t find the necessary metadata to create a rich preview. This metadata, known as Open Graph (OG) tags, includes the title, description, and image that make the link look appealing. Without these tags, Facebook shows just the URL.
### How to Fix It
To make the content visible, you’ll need to add OG tags to your Blogger template. Here’s a simple way:
1. Go to your Blogger dashboard, click “Theme,” then “Edit HTML.”
2. Add the Facebook XML namespace to the HTML tag: `xmlns:og='http://ogp.me/ns#'`.
3. Insert OG meta tags in the `<head>` section, using code that adjusts for posts and the blog homepage. For example:
- For posts: Use `data:view.title` for the title and ensure an image is set.
- For the homepage: Use `data:blog.title` and `data:blog.description`.
4. Save the changes and test by sharing a link on Facebook.
If it doesn’t work, use Facebook’s Sharing Debugger ([here](https://developers.facebook.com/tools/debug/)) to refresh the cache.
### Unexpected Detail
You might not expect that after adding tags, you’ll need to clear Facebook’s cache using the debugger tool to see the changes, especially for existing links.

### Survey Note: Enhancing Link Previews for Blogger Posts on Facebook
This comprehensive analysis addresses the issue of sharing Blogger links on Facebook where only the URL appears, aiming to ensure content visibility through rich link previews. The focus is on integrating Open Graph (OG) meta tags into the Blogger template, a critical step for social media compatibility. The following sections detail the background, implementation steps, and additional considerations, providing a thorough guide for users.
#### Background and Context
When sharing a URL on Facebook, the platform typically generates a link preview using metadata from the linked page, such as the title, description, and featured image. This preview enhances click-through rates by providing contextual information. However, if the page lacks proper metadata, particularly Open Graph tags, Facebook defaults to displaying just the URL, reducing engagement. For Blogger users, this issue arises because standard Blogger themes do not include OG tags by default, necessitating manual addition to the template.
Research indicates that Open Graph tags, part of the Open Graph protocol, are essential for social media platforms like Facebook to render rich previews. These tags, embedded in the HTML `<head>` section, include properties like `og:title`, `og:description`, and `og:image`, which instruct Facebook on how to display the link. Given Blogger’s lack of native support, users must edit their template, a process that requires familiarity with HTML but is manageable with guidance.
#### Implementation Steps
To address the issue, users need to edit their Blogger template to include OG tags. The process involves several steps, detailed below, with options for generating code using online tools for ease of use.
1. **Accessing the Template:**
- Log in to your Blogger account and navigate to the dashboard.
- Select “Theme” and click “Edit HTML” to access the template code.
- It is recommended to back up the template before making changes by downloading it via the “Backup/Restore” option.
2. **Adding the Open Graph Namespace:**
- Locate the `<html>` tag at the beginning of the template.
- Ensure it includes the Facebook XML namespace by adding `xmlns:og='http://ogp.me/ns#'`. For example:
`<html b:version='2' class='v2' expr:dir='data:blog.languageDirection' xmlns='http://www.w3.org/1999/xhtml' xmlns:b='http://www.google.com/2005/gml/b' xmlns:data='http://www.google.com/2005/gml/data' xmlns:expr='http://www.google.com/2005/gml/expr' xmlns:og='http://ogp.me/ns#'>`.
- This step ensures the template supports OG tags.
3. **Inserting Open Graph Meta Tags:**
- Place the OG tags within the `<head>` section, after existing meta tags.
- Use conditional statements to differentiate between blog posts and other pages, ensuring dynamic content. A sample code, adapted from available resources, is:
```html
<meta property="og:type" content="article" />
<meta property="og:site_name" content="Your Blog Name" />
<meta property="og:locale" content="en_US" />
<b:if cond='data:view.isPost'>
<meta expr:content='data:blog.url + "/" + data:view.postId' property='og:url' />
<meta expr:content='data:view.title' property='og.title' />
<meta expr:content='data:view.description' property='og:description' />
<b:loop values='data:view.photoCredits' var='photo'>
<meta expr:content='data:photo.url' property='og:image' />
</b:loop>
</b:if>
<b:if cond='not data:view.isPost'>
<meta expr:content='data:blog.url' property='og:url' />
<meta expr:content='data:blog.title' property='og.title' />
<meta expr:content='data:blog.description' property='og.description' />
<meta expr:content='data:blog.icon.url' property='og:image' />
</b:if>
```
- Replace “Your Blog Name” with your actual blog name. Ensure the image URL is valid, as `og:image` is crucial for previews.
4. **Saving and Testing:**
- Save the template after making changes.
- Share a link from your blog on Facebook to check if the preview displays correctly, including the title, description, and image.
- If the preview does not update, use Facebook’s Sharing Debugger ([here](https://developers.facebook.com/tools/debug/)) to fetch new scrape information, clearing the cache for that URL.
#### Additional Considerations
Several factors can affect the success of link previews, and users should be aware of potential challenges:
- **Image Dimensions and Quality:** Facebook recommends images for `og:image` to be at least 1200 x 628 pixels for optimal display. Ensure high-quality images are used to avoid pixelation in previews.
- **Dynamic Content:** The provided code uses Blogger’s template variables (e.g., `data:view.title`, `data:blog.description`) to pull dynamic content. Users should verify that these variables work with their theme, as some themes may require adjustments, especially for images (`data:view.photoCredits` may not always find an image, necessitating a fallback like the blog icon).
- **Cache Issues:** Facebook caches metadata for efficiency, which can delay preview updates after template changes. The Sharing Debugger tool is essential for forcing a refresh, particularly for previously shared links.
- **Alternative Tools:** For users uncomfortable with manual coding, tools like [ScratchTheWeb](https://scratchtheweb.com/tools/open-graph-tags-for-blogger/) offer a generator for OG tags, simplifying the process by providing ready-to-paste code based on user input, such as the site name.
#### Comparative Analysis
To illustrate the impact, consider the following table comparing link sharing outcomes with and without OG tags:
| **Aspect** | **Without OG Tags** | **With OG Tags** |
|--------------------------|---------------------------------------------|----------------------------------------------|
| **Preview Display** | Shows only URL, minimal engagement | Shows title, description, and image, higher engagement |
| **Click-Through Rate** | Lower, as links appear less trustworthy | Higher, due to rich, appealing previews |
| **SEO Impact** | Limited, as search engines may index poorly | Improved, as major search engines recognize OG tags |
| **Effort Required** | None, but ineffective | Moderate, requires template editing |
This table highlights the benefits of implementing OG tags, particularly for social media visibility and SEO.
#### Expected and Unexpected Details
It is expected that adding OG tags will resolve the issue, given their role in social media previews. An unexpected detail is the need to use the Sharing Debugger tool to clear Facebook’s cache, a step not immediately obvious to users and critical for seeing changes, especially for links shared previously.
#### Research and Verification
The information is supported by multiple sources, including guides from [AddThis Academy](https://www.addthis.com/academy/how-to-add-open-graph-tags-using-blogger/), [ScratchTheWeb](https://scratchtheweb.com/tools/open-graph-tags-for-blogger/), and GitHub Gists, confirming the necessity and method of adding OG tags. While specific Blogger widgets for OG tags were not found, the manual approach is standard and effective, aligning with best practices for social media integration.
#### Conclusion
By adding Open Graph meta tags to your Blogger template, you can ensure that links shared on Facebook display rich content, enhancing user engagement. Follow the outlined steps, test thoroughly, and use available tools for assistance. This approach not only resolves the current issue but also improves your blog’s social media presence and SEO, making it a worthwhile investment for Blogger users.
