This is What Causes Your Screenshot to be Cached Too Soon on LinkedIn (and How to Fix it)
As a content creator, you work hard to craft the perfect blog post, complete with eye-catching visuals and a compelling message. When it's time to share your hard work on LinkedIn, you expect the image preview to accurately reflect your latest changes. But what if that image seems outdated or is simply missing?
This frustrating issue is a common problem faced by many WordPress users, and it's all due to the way LinkedIn caches your website's Open Graph (og:) data. In this article, we'll dive into the root cause of this problem and provide practical solutions to ensure your LinkedIn shares always display the correct, up-to-date image.
Understanding the Issue: Why Does LinkedIn Cache og:image Data Too Soon?
The core of the problem lies in the way LinkedIn interacts with your website's Open Graph (og:) metadata. Open Graph is a protocol that allows you to control how your content is displayed when shared on social media platforms, including LinkedIn.
When you share a link on LinkedIn, the platform will scan your website's HTML and extract key pieces of information, such as the page title, description, and most importantly, the og:image. This is the image that will be displayed as the preview when your content is shared.
The issue arises because LinkedIn caches this og:image data quite aggressively, often for up to 7 days. This means that even if you update the image on your website, LinkedIn will continue to display the cached version until the cache expires.
For example, let's say you publish a new blog post with a screenshot as the featured image. You then share this post on LinkedIn, and the image preview looks perfect. But a week later, you decide to update the screenshot to include additional information. When you re-share the post, LinkedIn will still display the old, outdated image because it's pulling from its cached version.
This can be incredibly frustrating, as it can make your content appear outdated or unprofessional, and it can also negatively impact the engagement and click-through rates of your LinkedIn shares.
Solving the Problem: Techniques to Ensure LinkedIn Always Displays the Correct Image
Fortunately, there are several techniques you can employ to ensure LinkedIn always displays the correct, up-to-date image when you share your content. Let's explore some of the most effective solutions:
1. Leverage the LinkedIn Share Button
One of the easiest ways to ensure LinkedIn displays the correct image is to use the official LinkedIn share button on your website. This button is designed to provide a seamless sharing experience, and it helps bypass some of the caching issues associated with manually copying and pasting the URL.
When you use the LinkedIn share button, the platform will re-fetch the og:data from your website every time the button is used, ensuring that the latest information is displayed. This can be particularly useful if you update your content frequently or if you want to ensure that the image preview is always up-to-date.
To implement the LinkedIn share button on your WordPress site, you can use a plugin like Shared Counts or Social Pug, both of which provide easy integration options.
2. Clear the LinkedIn Cache Manually
If you've already shared your content on LinkedIn and the image preview is outdated, you can try clearing the cache manually. To do this, follow these steps:
- Visit the LinkedIn Post Inspector and enter the URL of your shared content.
- Click the "Fetch" button to force LinkedIn to re-fetch the og:data from your website.
- If the image preview still appears outdated, you can click the "Clear Cache" button to remove the cached data and force LinkedIn to re-fetch the latest information.
Keep in mind that this method may not always work, as LinkedIn's caching policies can be quite aggressive. However, it's worth trying if you need to quickly update the image preview for a specific piece of content.
3. Use a Cache-Busting Technique
Another solution to the LinkedIn caching issue is to use a cache-busting technique. This involves appending a unique query parameter to the end of your image URL, which forces LinkedIn (and other social media platforms) to re-fetch the image data instead of using the cached version.
Here's how you can implement this technique:
- When you update your featured image, append a unique query parameter to the end of the image URL. For example, you could use a timestamp or a random number:
?v=1234567890
.
- Update the og:image tag in your WordPress site's HTML to reflect the new URL with the query parameter.
By using a unique query parameter, you're essentially telling LinkedIn and other platforms that the image has changed, even if the file name remains the same. This forces them to re-fetch the image data, ensuring that the latest version is always displayed.

4. Disable LinkedIn's Image Caching
If you're willing to go a step further, you can consider disabling LinkedIn's image caching altogether. This can be done by adding the following meta tag to your website's HTML:
<meta name="linkedin-disable-image-cache" content="true">
This meta tag tells LinkedIn not to cache any images from your website, ensuring that the latest version is always displayed. However, keep in mind that this approach may have some drawbacks, as it could potentially increase the load time of your shared content on LinkedIn.
5. Utilize a Content Delivery Network (CDN)
If you're using a Content Delivery Network (CDN) to serve your website's assets, including images, you can leverage this to overcome the LinkedIn caching issue.
CDNs often have their own caching mechanisms that can be configured to ensure that your images are always up-to-date. By setting appropriate cache-control headers or using techniques like cache busting, you can ensure that LinkedIn always fetches the latest version of your images, even if they're being served from a CDN.
This approach can be particularly useful if you're dealing with high-traffic websites or if you need to update your images frequently.
Conclusion: Taking Control of Your LinkedIn Shares
Ensuring that your LinkedIn shares always display the correct, up-to-date image is crucial for maintaining a professional and engaging online presence. By understanding the root cause of the issue and implementing the solutions we've outlined, you can take control of your LinkedIn shares and ensure that your content always makes a great first impression.
Remember, the key to success is to stay proactive and be willing to try different techniques to find the one that works best for your specific use case. With a little bit of effort, you can ensure that your LinkedIn shares always showcase your content in the best possible light.
