Social Media Preview: Uploading an Image in SEO
Learn how to set a social media preview image in Super’s SEO settings so your site links display correctly when shared on LinkedIn, Facebook, X, and other platforms.
A social media preview image controls how your site or page appears when shared on platforms like LinkedIn, Facebook, X (Twitter), and other social platforms. Adding a preview image helps your links look more professional, eye-catching, and clickable.
Super supports two types of social media preview images:
Custom Social Image — A specific image you set for an individual page.
Default Social Image — A fallback image that is automatically used when a page does not have a custom social image.
This feature requires an active Super subscription.
Why Social Media Preview Images Matter
When someone shares your site link on social media, the platform automatically pulls metadata such as:
Page title
Description
Preview image
Without a preview image, your link may appear plain or incomplete, which can reduce engagement.
Using a Default Social Image also ensures that pages without a custom image still have an image available when shared.
Requirements
Before setting a social media preview image, make sure that:
You have an active Super subscription
Search Engine Indexing is enabled for your site
The page is published and indexable
Set a Default Social Image
The Default Social Image is used as a fallback for pages where you haven't uploaded a custom social media preview image.
For example, if you have 20 pages on your site and only 5 of them have custom social images, the remaining pages can use your Default Social Image when shared on social media.
To set your default image:
Go to your SEO Section
Open your Super dashboard and navigate to SEO.
Enable Search Engine Indexing
Ensure that Search Engine Indexing is turned on. This is required for social platforms to read your page metadata.
Find the Default Social Image option
Locate the Default Social Image setting and upload the image you'd like to use as the fallback image.
Save your changes
Your default social image will now be used for pages that don't have a custom social image.
Upload a Custom Social Image for a Specific Page
If you want a particular page to have its own social media preview image, you can upload a custom social image for that page.
Go to your SEO Section
Open your Super dashboard and navigate to SEO.
Enable Search Engine Indexing
Ensure that Search Engine Indexing is turned on.
Click “Update Page SEO Settings”
This allows you to customize SEO details for individual pages.
Choose the page
Select the page where you want to set a custom social media preview image.
Scroll down to the Social Preview section
Upload your desired image in the image upload field.
Click “Save Changes”
Your custom social media preview image is now set for that page.
How the Images Work Together
Super uses the images in the following order:
Custom Social Image → Default Social Image
If a page has a Custom Social Image, that image will be used when the page is shared.
If no custom image has been set for the page, Super will use the Default Social Image instead.
If neither is configured, the page may be shared without a social preview image.
Best Practices for Preview Images
For best results across social platforms:
Recommended size: 1200 × 630 px
Keep important text centered, as edges may be cropped
Avoid small or overly detailed text
Use an image that works well as a general fallback if you're setting a Default Social Image
Final Notes
Changes may not appear instantly on social platforms due to caching. If needed, use platform tools like:
LinkedIn Post Inspector
Facebook Sharing Debugger
X Card Validator
These tools can help refresh how your link is displayed and verify that the correct preview image is being used.
