How to Use the Facebook Debugger to Correct the Facebook Link Preview?

If you are a marketer, publisher, or blogger, you must know about Facebook Debugger. It is a beneficial tool for scraping the URL of your blog post or web page. Facebook creates a cache of your URL, which depends upon Open Graph or Schema metadata. When you create, publish, and share a blog post on Facebook, a cache for this post is created for at least 30 days.

Imagine you update the blog post title, description, or featured image, and then what will Facebook show when you share it again? It will not show your updates. Here, the importance of the Facebook Debugger tool comes into play. It is also known as an FB debugger, Facebook sharing Debugger, Facebook URL debugger, or Facebook link debugger.

Let’s check out how to use the Facebook debug tool to scrape the URL and update the Facebook link preview.

How Facebook Debug Tool Scrapes Data?

Facebook link debugger is a handy tool; it does not matter which blogging platform you use. It is different from Facebook Object Debugger. It is useful for WordPress, Blogger, Ghost, and all. Earlier, I told you that the Facebook URL debugger scrapes information using meta tags. If meta tags are absent, it will work like Google and identify the H1 or H2 tag to show the title, the first paragraph as a description, and the first image as a featured image. After sharing a post, Facebook will make a cache and won’t delete it automatically. You need to do it manually using Facebook Sharing Debugger. This information about FB debugger is beneficial for a tech geek or social media people like you.

Why is Facebook Not Scraping OG Information Correctly?

  1. Not using Open Graph correctly.
  2. You’ve updated the blog but did not clear the WordPress cache.
  3. Did not set any featured image to a blog or website.
  4. Not using the correct image size. It should be 1280×853 or maintain a ratio when using a larger image.
  5. Facebook cache for your blog already exists.

Step 2: Review the Open Graph Markup

Now, Facebook Share Debugger shows where a glitch is and what to fix. Warnings help you analyze what you need to do to correct the problem.

Facebook Debugger can show these frequent warnings:

Inferred Property: It means no image is available to use as a thumbnail or multiple image properties are set. In the second case, Facebook chooses one among the available options.

Extraneous Property: It is about “og” properties. This warning will appear when one of the “og” properties is unrecognized or depreciated. You can identify that particular “og” property and fix it quickly.

Missing App ID: This warning is related to the “fb:app_id” property that is unspecified in your blog or website. If you have a separate app, then this warning may be shown.

Parser mismatched metadata: This means scraped data does not match the original. This is due to the wrong date format or extra spaces in the title. The warning shows which property should be fixed. The following are the most used “og” properties:

Just fix the issues causing trouble with your blog post, then scrape the link again and check if everything is as expected.

Step 3. Flush the WordPress Cache

If you have trouble scraping Open Graph metadata correctly, remember to clear the WordPress or Cloudflare cache and try again, i.e., scrap the link.

It may or may not help you fetch the correct Open Graph tags. If you are not able to get the result, try Open Graph Object Debugger.

How to Use Open Graph Object Debugger?

After flushing the cache and scraping again, if correct information is not showing up, you need to use the Facebook Open Graph debugger, also known as the Facebook object debugger.
