Link Preview - Troubleshooting checklist and solutions for setting Open Graph Tags

2021-04-26 15:25

Open Graph tags (og:tags) are one of the most important things to make your blog or website social-media-ready. OG tags define how your link preview (snippet), containing your title, description and image to give a preview of your article, is presented in your social media posts.

If your post was shared with a wrong image or without any image, with the wrong title or description, please go through the following points and check your blog posts with them:


   ⃣ Check source code
   ⃣  Check other plugins which set open graph tags
   ⃣ Change open graph tags
   ⃣ Check post templates

  ⃣  Check source code

First of all, you can check the open graph tags by calling up your blog post or site and making a right-click with your mouse anywhere between the lines of the blog post in some free space to open a menu.

Click on “View Page Source” to open the source code. A new window or tab with the source code will open.


1. Press Ctrl+F (on Windows) to open the search bar.


2. Type in “og:image” and press the enter key. The og:image tag will now be highlighted in your source code.


The line
><meta property="og:image" content=" jpg" / ><
shows the image that is set as the og:image for this blog post.

You can also search for “og:title” to check the title tag or “og:description” to check the description tag.

  ⃣  Check other plugins which set open graph tags

If you notice that any of the og:tags are set more than once while checking the source code, some social networks might not be able to read your tags. Please make sure that you use only Blog2Social to set meta tags and disable all other plugins which set these meta tags.

  ⃣  Change open graph tags

When you checked the open graph tags and noticed that there is set a wrong image, title or description, you can change the tags and share your post again.

Please note: There may also be delays caused by the networks. Sometimes the networks need a few minutes to process the data. Just reload the page to see if the networks show the post correct now.
