Facebook Sharing Debugger: How to Fix the Wrong Website Preview

Have you ever shared your website or blog post on Facebook and thought:

Why does my website look completely different here?

Maybe Facebook shows the wrong image.

An old title.

A description you already changed.

Or perhaps no image appears at all.

Your website looks fine when you open it.

Your SEO settings look correct.

Google may even display the page properly.

But Facebook seems to have its own idea.

This is exactly where the Facebook Sharing Debugger becomes useful.

Why Does Facebook Show My Website Differently?

When you share a URL on Facebook, Facebook does not simply take a screenshot of your website.

Meta uses its own crawler to visit the URL and collect information about the page.

The Facebook Crawler looks for Open Graph metadata that tells Facebook what it should use for the link preview.

Important Open Graph tags include:

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

According to Meta’s documentation, if these tags are missing, the Facebook Crawler may use its own internal logic to guess which title, description, and image should appear.

And sometimes that guess is not the one you wanted.

What Are Open Graph Tags?

Open Graph tags are small pieces of metadata inside your website code.

Visitors normally do not see them.

Platforms such as Facebook use them to understand how your page should be presented when someone shares the URL.

For example:

<meta property="og:title" content="Your Article Title" />
<meta property="og:description" content="Your article description." />
<meta property="og:image" content="https://example.com/image.jpg" />

This gives Facebook much clearer instructions.

Instead of asking the crawler to guess, you are effectively saying:

This is my title.
This is my description.
This is the image I want you to use.

Meta specifically recommends Open Graph markup for controlling how web content appears when shared on Facebook.

If you use WordPress with an SEO plugin such as Rank Math or Yoast, much of this can usually be configured without manually editing HTML.

But I Already Changed the Image. Why Is Facebook Still Showing the Old One?

This is another common problem.

Facebook caches information it has already collected about a URL.

So you might:

change your featured image,

rewrite the title,

update the description,

publish the changes…

…and Facebook still shows the previous version.

That does not necessarily mean your website is broken.

Facebook may simply still have older information stored for that URL.

This is why I recommend knowing about the Facebook Sharing Debugger even if you are not a developer.

How to Use the Facebook Sharing Debugger

The process is simple.

Go to:

Open the Facebook Sharing Debugger

Enter the URL that is giving you problems.

The tool will show you information Facebook has collected about that page, including the metadata its crawler can see and possible errors or warnings. Meta also states that running a URL through the debugger triggers a new scrape of the page.

Check:

• the preview image
• title
• description
• canonical URL
• Open Graph properties
• crawler warnings

If you recently updated the page, ask Facebook to scrape the URL again.

Then check the preview.

Very often, that is all you need.

What If the Preview Is Still Wrong?

Then I would check the website itself.

Make sure your page has the correct:

Open Graph title

og:title

Open Graph description

og:description

Open Graph image

og:image

Canonical URL

og:url

Meta recommends explicitly defining this information rather than leaving its crawler to determine the preview through heuristics.

Also check that Facebook’s crawler is actually able to access your website. Server rules, security tools, or crawler restrictions can prevent Meta’s web crawlers from reading a page correctly. Meta documents the user agents used by its web crawlers for exactly this type of troubleshooting.

Your Website and Your Social Media Presence Are Connected

This may look like a small technical issue.

But it illustrates something I write about frequently.

Your website does not exist separately from the rest of your digital presence.

Someone may discover your article through Google.

Another person may find it through Facebook.

Someone else may receive it through your newsletter.

The content is the same.

But the way it is presented across those channels matters.

A broken image or outdated title can make good content look unfinished before someone even clicks.

This is one of those small connections that becomes important when you start thinking about your online presence as a digital ecosystem.

Your website.

Search.

Social media.

Email.

Content.

They should support each other.

Final Thoughts

If Facebook is showing the wrong image, title, or description when you share your website, do not immediately assume something is wrong with the page itself.

First check what Facebook actually sees.

The Facebook Sharing Debugger is one of the simplest tools for doing that.

Use it to inspect your URL, see which Open Graph information Facebook has collected, identify possible problems, and trigger a fresh scrape after making changes.
