Incorrect Thumbnail Picture

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.

Could you please confirm if you have used your logo in Rank Math > Titles & Meta > Global Meta > OpenGraph Thumbnail?

If so, that would explain why it is always used for the og:image tag on your other pages. Since it is the default OpenGraph image, you can bypass it by following the step in this link:

If you have already change the image in the social tab, please ensure that the image file format you are uploading is only between jpeg, gif, or png, and the image resolution is as close as 1200 x 630 pixels as per Opengraph Standards.

Once done, clear your website’s cache and check again.

I hope that helps.

Thank you.

Hello,

The default social sharing image (Titles & Meta) shows up only when:

1. You have not uploaded any featured image to a post.
2. You are not using even a single image inside the post.
3. You have not used any image in the social tab.

If any of these are true, then that image will be used instead of the default social image. If you wish to force the use of the default social image, please paste this code into your theme’s functions.php file:

add_filter('rank_math/opengraph/pre_set_content_image', function() {
	return true;
});

Also, please resize the logo you are using to as close as 1200 x 630 pixels. Once done, clear your website’s cache and check again.

Let us know how this goes.

Thank you.
