What is LinkedIn post inspector and how to use it?

Have you ever shared a link on LinkedIn only to discover the preview looks completely wrong—missing image, outdated title, or a description you last used months ago? Poor link previews on LinkedIn can cut your comment rate in half, and in 2025 this matters more than ever. That’s exactly why the LinkedIn post inspector exists. This free tool helps you fix link preview issues before they hurt your engagement.

Below, you’ll find a complete guide that explains what the LinkedIn post inspector is, why link previews break, and how to use it step-by-step to ensure your content always looks professional.

What is LinkedIn post inspector?

The LinkedIn post inspector is a free diagnostic tool created by LinkedIn in 2018 to help users debug, optimize, and refresh link preview data. Think of it as a virtual fitting room for your content—it shows you exactly how your link will appear before you publish it.

Unlike general social media debuggers, the LinkedIn post inspector focuses solely on LinkedIn. This makes it uniquely accurate because it reflects precisely what LinkedIn’s algorithm sees when scanning your page.

Why should you use the tool?

The LinkedIn post inspector helps fix three crucial preview issues:

• Preview visualization: You can view the image, title, and description exactly as your audience will see them.
• Error identification: The tool highlights missing or incorrect metadata so you can fix problems quickly.

For content creators, marketers, and businesses, this tool is a must-use step before publishing links. A clean preview boosts clicks, improves engagement, and helps your content look polished and intentional.

Why link previews break on LinkedIn

Before learning how to use the LinkedIn post inspector, it’s important to understand why previews break in the first place. Three main problems cause most issues.

Outdated cache displaying old content

LinkedIn stores link information for up to a week. Even if you change your blog’s title or featured image, LinkedIn may continue showing the old data. This happens because LinkedIn relies on cached snapshots instead of re-scraping your website automatically. If you frequently update your content, this can lead to endless frustration—unless you know how to refresh the cache using the LinkedIn post inspector.

Missing or wrong Open Graph tags

Open Graph (OG) tags control how shared content appears on social platforms. Missing or incorrect tags lead to broken or incomplete previews. LinkedIn relies on essential OG metadata such as:

• og:title
• og:image
• og:description
• og:type
• og:url
• og:locale

Without these properly configured tags, LinkedIn cannot display your content correctly. Some platforms—like WordPress—don’t include OG tags by default, so additional plugins may be necessary.

Image or title that doesn’t meet LinkedIn requirements

LinkedIn uses strict specs for images and text. Issues appear when:

• Images aren’t 1200×627 pixels
• Aspect ratio isn’t 1.91:1
• Titles exceed 150 characters
• Images load slowly
• Files use unsupported formats like WebP

Failing to meet these guidelines often results in tiny thumbnails, cropped images, or missing previews.

How to Use LinkedIn Post Inspector (Step-by-Step)

Now let’s walk through exactly how to use the LinkedIn post inspector to fix broken previews and ensure your link displays beautifully.

Step 1: Go to the LinkedIn post inspector

You can access the tool directly in your browser at: linkedin.com/post-inspector

You can also search “LinkedIn post inspector” on Google. No login is required—anyone can use it.

Step 2: Paste your URL and click “Inspect”

Once the tool opens, you’ll see a simple input box at the top.

1. Copy the full URL you want to share
2. Paste it into the input bar
3. Click the Inspect button

The tool will now scan your page, fetch metadata, and display a complete preview analysis.

Step 3: Review the preview and metadata

After inspecting, the tool will display:

Preview image

You’ll see exactly how your thumbnail will appear, helping you detect sizing or cropping issues.

URL information

This includes:

• The fetched URL
• Canonical URL
• Redirects
• Last time LinkedIn scraped your page

If the date looks old, your preview is likely outdated.

Metadata details

This includes:

• Title
• Description
• Content type
• Author
• Publication date

Each metadata element also shows any alternate values LinkedIn considered.

Ingestion feedback

This section identifies problems, such as missing OG tags or incorrect image formats.

To get the best results from the LinkedIn post inspector, follow these tips:

Update your metadata before sharing

Optimize:
