Welcome to the future of image troubleshooting on Facebook! With the Facebook Image Debugger tool, fixing image display issues has never been easier. Whether your image isn’t showing correctly or you need to optimize tags, this guide will show you how to use the Debugger to perfect your visuals. Say goodbye to frustrating image glitches and make sure your content always looks its best on Facebook. Let’s dive into the quick and easy way to debug and elevate your images!
What is Facebook Image Debugger?
Facebook Debugger, commonly known as the Facebook Sharing Debugger, is an essential tool designed for developers and content creators to help them understand and optimize how their content appears when shared on Facebook. This tool plays a crucial role in ensuring that your posts look their best and convey the right message to your audience. Let’s take a closer look at its features and functions.
1. Sharing Debugger
The Facebook Sharing Debugger tab is the heart of the tool. When you enter a URL into this section, it retrieves the metadata associated with that link. This includes vital information such as:
- Title: The headline that will appear when the link is shared.
- Description: A brief summary of the content, providing context to viewers.
- Featured Image: The visual that accompanies your post, crucial for catching the eye of potential readers.
The Sharing Debugger allows you to see exactly what users will see when they share your content on Facebook or Messenger. If there are any issues—like incorrect images, missing descriptions, or outdated titles—the tool will highlight these problems, enabling you to fix them before sharing.
Additionally, if you make updates to your content or change images, the Sharing Debugger lets you “scrape” the URL again. This process refreshes the cached information, ensuring that the latest version of your content is displayed.
2. Batch Invalidator
The Batch Invalidator is a powerful feature for those managing multiple URLs. Instead of updating each link individually, this tool allows you to input several URLs at once and refresh their cached data simultaneously. This is especially useful for:
- Bulk updates: When you’ve made widespread changes to your website or blog.
- Time-saving: Instead of waiting for each URL to update one by one, you can process many links in a single action.
Using the Batch Invalidator helps ensure that your audience always sees the most current version of your content, which is essential for maintaining engagement and credibility.
3. Access Token
The Access Token tool provides a way to authenticate requests to the Facebook API. While it’s a useful feature for developers working with Facebook’s tools and services, it isn’t the primary focus of the Sharing Debugger. As such, we won’t delve deeply into its specifics here, but it’s worth noting that it can be helpful for more advanced functionalities if you’re integrating Facebook features into your applications.

How Facebook Selects the Image and Caption for Your Blog Posts Using the Facebook Sharing Debugger Tool
A. Components of a Facebook Preview
- Introduction: The introduction is the text that the person sharing the post writes. It can be a personal message, comment, or note encouraging others to check out your blog post.
- Image: The image is a key visual element that captures attention. It can significantly influence whether users decide to click on the blog post.
- Caption: The caption is a brief description or title that accompanies the image. It provides context and entices users to engage with the post.
B. How Facebook Determines the Image and Caption
Facebook uses a crawler, an automated bot, to select the image and caption for your blog post preview. The process works as follows:
- Scraping the HTML:
- When a blog post is shared on Facebook, the crawler retrieves the HTML code of the webpage.
- The crawler looks for specific meta tags, mainly Open Graph tags, which provide structured data about your content.
- Selecting Content: The crawler looks for the following Open Graph tags:
- og:image: Specifies which image to display in the preview. If multiple images are available, the crawler selects the one indicated by this tag.
- og:title: Provides the title (caption) that accompanies the image.
- og:description: Offers additional context, though the title and image are most prominently displayed.
C. Caching Mechanism
- After Facebook scrapes your page, it stores the scraped information in its cache for 30 days.
- If another user shares the same post within that period, Facebook will reuse the cached image and caption instead of re-scraping the page.
D. Potential Issues with Scraping
Several issues can occur during the scraping process, leading to incorrect previews:
- Wrong Image Selection: Facebook may display an unintended image if:
- Open Graph tags are missing or incorrect, causing the crawler to select a random image.
- The crawler picks a different image found in the HTML, rather than the one specified by the Open Graph tags.
- Outdated Previews: If you update the blog post (e.g., changing images or headlines), Facebook may continue displaying the old version of the preview if:
- The cache hasn’t expired, causing Facebook to reuse the previous information.
- Changes made to Open Graph tags are not recognized until the cache is cleared.
- Incorrect Open Graph Tags: If the Open Graph tags are not properly configured, Facebook may display incorrect data or fail to generate a preview altogether.
E. Using the Facebook Sharing Debugger Tool
To ensure that your content is displayed correctly on Facebook, you can use the Facebook Sharing Debugger Tool. This tool helps in the following ways:
- View Facebook’s Cached Version: The tool shows how Facebook views your webpage, including the cached image and caption.
- Clear the Cache: If you’ve updated your blog post, you can use the tool to force Facebook to re-scrape your page, clearing the outdated cache and showing the updated preview.
- Fix Open Graph Metadata: The tool identifies any issues with your Open Graph tags, allowing you to adjust them and ensure that the correct image and caption are shown.
By using the Facebook Sharing Debugger Tool, you can ensure that your blog post’s image and caption appear exactly as you intend when shared on Facebook.

Why Does Facebook Display the Wrong Content?
Sharing blog posts on Facebook can be a fantastic way to drive traffic and engage with your audience. However, it’s not uncommon to encounter issues where the wrong image, title, or description is displayed. Understanding the reasons behind these discrepancies is crucial for addressing them effectively. Here’s a detailed look at some of the most common reasons why Facebook may show incorrect content when you share your posts.
1. Incorrect Use of Open Graph Tags
Open Graph tags are HTML elements that help control how your content appears on social media platforms like Facebook. When you share a link, Facebook looks for these tags to determine what information to display. If these tags are incorrectly configured, missing, or point to outdated URLs, Facebook may pull default information from your webpage instead.
For instance, if you forget to include the og:image tag, Facebook might select a random image from your page or use a placeholder image that doesn’t represent your content. Similarly, if the og:title and og:description tags are not set correctly, the platform may display generic titles or descriptions that fail to capture your audience’s attention.
2. Not Clearing the WordPress Cache
If you’re using WordPress with a caching plugin, it’s essential to understand how caching works. Caching plugins store static versions of your pages to enhance load times, but they can also lead to displaying outdated content. If you’ve made updates to your blog post—such as changing images or editing text—Facebook may continue to show the cached version unless you clear the cache.
Failure to clear your WordPress cache after making changes means that Facebook could be pulling from old data. This can be particularly problematic if your post has been shared multiple times, as the cached version may not reflect the latest updates.
3. Forgetting to Add a Featured Image
A featured image serves as the main visual representation of your blog post and is typically the image Facebook will display when sharing the link. If you forget to set a featured image, Facebook may select a random image from the content of your post or use a default placeholder image. This can result in an unappealing or irrelevant image appearing in the preview, which can diminish the post’s effectiveness and engagement.
Not having a well-chosen featured image can lead to lower click-through rates, as users are often drawn to visually appealing content. An attractive image that aligns with your post’s message can significantly enhance engagement.
4. Using the Incorrect Image Size
Facebook has specific image size recommendations to ensure that your content is displayed properly. If the images you use do not meet these size requirements, they may be cropped, distorted, or displayed poorly in the preview. For example, the optimal dimensions for linked post images are 1200 x 628 pixels. If your image is smaller than this or has the wrong aspect ratio, it may not render correctly, which could detract from its visual appeal.
Using images that don’t comply with Facebook’s specifications can result in a less polished appearance, which can turn potential readers away. Ensuring that your images are the correct size is essential for creating professional-looking previews that attract clicks.
5. Facebook Already Scraped the Article
When you first share a link on Facebook, the platform scrapes the content to generate a preview. This scraped data is stored in Facebook’s cache for about 30 days. If you make changes to your article during that time—such as updating images or modifying the title—Facebook might still display the old version in the preview.
Unless you prompt Facebook to re-scrape your page, the cached information will remain unchanged. This can be particularly frustrating if you’ve made significant updates, as users will see outdated information that doesn’t accurately reflect your current content.
How to Use the Facebook Debugger Tool
Let’s walk through how to effectively use the Facebook Debugger tool to manage what appears when you share your blog articles on Facebook. If you want, you can follow along by debugging one of your own pages as we go through these steps.
Step 1: Navigate to the Facebook Debugger Tool
To get started, you can access the Debugger tool by going directly to the Sharing Debugger page. Alternatively, you can find it through Facebook for Developers by navigating to More > Tools > Sharing Debugger.
If you aren’t logged in, you’ll need to sign in with your Facebook account.
Once you’re on the Debugger page, it should default to the Debugger tab. If it’s your first time here, make sure the “Sharing Debugger” tab is highlighted.
Now you’re all set to use the tool!
Step 2: Enter the Website Address of the Page You Want to Test
Next, enter the URL of the webpage you want to review. This could be a blog post or any page from your site.
After entering the URL, click the “Debug” button and wait for the results to load.
Step 3: Review Facebook Debugger Results
The Debugger works quickly! Once you click “Debug,” the tool will analyze your webpage and generate results almost instantly.
At the top of the report, you’ll see a section labeled “Warnings.” This will highlight any issues that need fixing on your page.
Below that, the report will show when your page was last scraped and will list both the fetched and canonical URLs. You’ll also see a full preview of how your blog post or page will appear when shared on Facebook.
Step 4: Clear the Caches
If the preview doesn’t look right, start by clearing your caches. The preview might be showing an outdated version of your content because either WordPress or Facebook is still referencing old data.
- For WordPress Users: Clear your WordPress cache using your caching plugin.
- For Facebook: Click the “Scrape Again” button at the top of the Debugging report to refresh the cache.
If the preview is still off, move on to the next step to make adjustments.
Step 5: Adjust Open Graph Settings if Needed
If clearing your caches doesn’t resolve the issue, scroll down in the Debugger report to see more details about potential problems.
The lower half of the report provides in-depth information that your web team can use to address issues.
If your previews are still incorrect, the problem likely lies with your Open Graph tags (og tags). These are snippets of code you manually add to your pages to help Facebook and other platforms understand how to display your content.
Open Graph tags are crucial for integrating your site with social media. As marketing expert Neil Patel explains, they can significantly impact conversions and click-through rates, even though they don’t directly affect your on-page SEO.
If you’re using WordPress, you can manage Open Graph tags through plugins like Yoast SEO or Open Graph for Facebook, Google+, and Twitter Card Tags.
Step 6: Re-run Facebook Debugger to Verify Changes
Once you’ve identified and corrected the issues with your preview, clear your WordPress and Facebook caches again. Then, re-run the Facebook Debugger tool to check your changes.
The preview should now display exactly as you intended! This process ensures that your blog posts are presented optimally when shared on Facebook, helping to attract more clicks and engagement.
Why Is Facebook Debugger Not Working? Troubleshooting Possible Issues
When using the Facebook Debugger tool, you may encounter various issues that prevent it from functioning as expected. Understanding these potential problems can help you troubleshoot effectively. Here’s a detailed look at some common issues you might face while using the Facebook Debugger, along with their explanations.
1. Image Not Meeting Size Requirements
One of the most common errors encountered in Facebook Debugger is related to image size. For Facebook to share a URL successfully, the associated image must be at least 200×200 pixels. If your image falls below this threshold, you’ll receive an error message stating something like, “Provided og
is not big enough. Please use an image that’s at least 200×200 px.”
To address this issue, first check that the og:image tag is present in your HTML and that the specified image meets the minimum size requirement. If the tag is missing, Facebook will attempt to select the first image it finds on your webpage. If you’re confident that your image exceeds the size requirement yet still receive an error, verify that the og:image tag is correctly configured. The issue may arise because Facebook is retrieving an incorrect image from your site.
2. Issues with Relative URLs
If you’re trying to use relative URLs for your og:url or og:image tags, you might run into problems. Facebook requires all URLs to be absolute. Absolute URLs are crucial because they represent the canonical location of a resource, whether it’s a webpage or an image. This format allows Facebook to accurately attribute shares and likes to the correct URL and cache images properly.
If you receive a complaint from the Debugger about relative URLs, ensure that you are using absolute URLs in your Open Graph tags. This adjustment will help Facebook retrieve and display your content correctly.
3. Incorrect Image Displayed in Preview
Sometimes, you might find that the preview generated by the Debugger shows an incorrect image. If your webpage is utilizing Open Graph meta tags and includes the og:image entry, Facebook should fetch that specified image and display it in the preview. If your page provides the og:image, og:image:width, and og:image:height tags, Facebook will use that image from the first time it is shared.
If these conditions are not met, Facebook may take longer to scrape and analyze the images on your site. If you recently updated your Open Graph image or associated resource, it’s possible that the old image is still being displayed until Facebook’s crawlers have had a chance to fetch the updated content.
4. Updated Open Graph Images Not Showing
When you update your Open Graph image or associated resources, the new content might not immediately appear in new posts. This could be due to Facebook needing to re-scrape your page. Facebook does automatically update its cache over time, but you can also trigger a re-scrape manually using the Debugger tool. If you’ve made significant changes to your content, it’s advisable to use the Debugger to prompt Facebook to fetch the latest information.
5. Control Over Display Size in News Feed
When sharing your Open Graph content on Facebook, keep in mind that you cannot control how it will appear in the News Feed or Timeline beyond providing the appropriate Open Graph tags. Facebook optimizes the display of posts automatically to enhance engagement. Therefore, while you can specify images and descriptions in your OG tags, the final appearance in users’ feeds is managed by Facebook’s algorithms.
6. Accessing Instagram Posts and Open Graph Actions
If you’re trying to view Instagram posts or other Open Graph actions via the Graph API and finding that they aren’t being returned, it could be due to permission issues. Photos uploaded to Instagram are treated as Open Graph actions and require the appropriate Open Graph permissions for access.
For Instagram photos specifically, the required permission is user_actions:instapp, as this pertains to Instagram’s application namespace. Keep in mind that Open Graph actions do not appear on the /feed connection. Instead, they can be accessed with the right permissions through the user’s albums connection or /photos connection.
