When you share a webpage on LinkedIn, the platform builds a preview card using details from the page, such as its title, description, and image. These details are called metadata. LinkedIn Post Inspector lets you see what LinkedIn finds on the page and ask it to fetch the URL's information again.
If a preview is wrong, update the webpage first, then inspect the URL again. LinkedIn uses refreshed information for new posts. It does not replace the preview on a post that is already published. For WordPress publishers, PressQueue can also create a social image and use it as the page’s preview image.
Check the URL with LinkedIn Post Inspector
Sign in to LinkedIn Post Inspector. Paste the page URL, then select Inspect. Check the image and title, along with other page details and any warnings. The tool checks a webpage’s link preview; it does not preview all the text in your LinkedIn post. LinkedIn’s Post Inspector guidance describes using it to refresh URL information.
If the preview looks outdated or incorrect, check the public webpage itself. Its Open Graph metadata, a set of page tags that describes how the page should appear when shared, includes fields for the title and description, plus the image and page URL. LinkedIn lists these fields in its website-sharing requirements.
Update the page in your website editor and publish the change. If your site uses a content delivery network, a service that stores and serves copies of website files, clear its cached copy of the page or image before inspecting again. Then run Inspect again and check the URL in a new LinkedIn post draft.
For troubleshooting, LinkedIn recommends allowing 48 hours after a share or metadata change. The recommendation is a guideline, and LinkedIn gives no guaranteed cache expiration time. LinkedIn also states that refreshed information does not change previews in posts that are already published.
Make the preview image clear and shareable
LinkedIn recommends a link-preview image ratio of 1.91:1, with minimum dimensions of 1200 × 627 pixels and a maximum file size of 5 MB. Use an image that remains legible at a smaller size, and make sure LinkedIn can access it without signing in. Its sharing guidance notes that blocked or protected images can prevent a preview from displaying as expected.
A wrong title or image can also result when more than one plugin adds Open Graph tags to a WordPress page. Yoast warns that duplicate tags can lead to incorrect sharing details in its Open Graph troubleshooting guidance.
Create WordPress social images with PressQueue
PressQueue is a free, open-source WordPress plugin that shares WordPress posts through Buffer. Its social image feature creates a share image from the post title and site name. PressQueue can also use that image as the page’s og:image and twitter:image, which supply preview images to LinkedIn and other sharing services.
To use it, download pressqueue.zip from the PressQueue download page, then go to Plugins > Add Plugin > Upload Plugin in WordPress. Connect it to Buffer with a personal API key from your Buffer settings. The key lets PressQueue connect to Buffer. Then choose a social-image style under Settings > Social images. You can preview the design and adjust its background, font, text color, alignment, and site name.
In the link-preview settings, choose whether PressQueue should set its image for every post, only posts without their own image, or no posts. An image already set for a post in an SEO plugin takes priority. After publishing a change, inspect that post’s URL in LinkedIn Post Inspector to check the result.
PressQueue starts in test mode, where it records what it would share without sending posts. Test your sharing rules before switching to Live. For setup details, see the PressQueue documentation.
What to do when an old post still shows the wrong image
Post Inspector refreshes the information LinkedIn uses for future shares. It does not update a link preview in an existing published post. LinkedIn’s post-editing instructions also explain that editing a post does not replace its shared media.
If the old preview is a problem, publish a new post with the corrected URL preview after confirming it in a draft. LinkedIn Page admins have a separate option to customize an image and title while composing a Page post, but that feature does not change the webpage’s metadata or refresh existing posts.
