How to prevent the first content image being taken to og:image?

Hello,

Thank you for contacting Rank Math, and sorry for any inconvenience that might have been caused due to that.

To make sure that your og:image is displayed instead of the featured image, please follow the steps below:

1. Please make sure the social meta settings are configured, to do so please go through our detailed Knowledge Base article below:

2. Once done, kindly set the og:image in your post editor’s Rank Math SEO settings:

If this is empty, the featured image of the post will be used.

3. Please remember to upload the og:image of the recommended dimensions, which is not more than 1200 × 630 pixels.

We hope this information helps. Do let us know how that goes.

We would love to help you further.

Thank you
