Featured image

A featured image is a representative thumbnail used in most content management systems. In Document360, the featured image is used mainly for SEO purposes. Instead of appearing at the top of an article, it enhances link previews when the article is shared on external platforms and helps search engines display relevant imagery in results.

When to use a featured image

Add a featured image to an article when:

• The article is likely to be shared externally and you want the link preview to display a specific, relevant image.
• You want to improve how the article appears in search engine results.
• Your knowledge base uses Open Graph metadata and you want article-level control over the thumbnail image shown when links are shared.

Where the featured image appears

The featured image does not appear at the top of the article on your knowledge base site. Instead, it is used as the Open Graph (OG) image when the article URL is shared on external platforms:

• Social media: LinkedIn, Facebook, X (Twitter), and Slack display the featured image as the link preview thumbnail.
• Search engines: Google and other search engines may use the featured image in rich results and search snippets.
• Messaging apps: Apps that support link unfurling, such as Microsoft Teams, will also display the featured image.

Add a featured image to an article

1. Open any article in the knowledge base portal.
2. Click the More () icon in the article header and select More article options.
3. In the Article settings panel, select the Featured image tab.
4. Click Upload an image. The Drive file picker opens.
5. Select the image and click Insert.
6. A preview of the image appears. Click Save.

Remove or replace a featured image

1. Open the article in the knowledge base portal.
2. Click the More () icon in the article header and select More article options.
3. In the Article settings panel, select the Featured image tab.
4. To replace the image, click Upload an image and select a new image from Drive.
5. To remove the image, click Remove featured image and click Save.

Fallback behaviour when no featured image is set

If an article does not have a featured image, the behaviour when sharing the article link depends on your project configuration:

• If a default featured image has been configured for your knowledge base, that image is used as the fallback thumbnail for all articles without an individual featured image.
• If no default featured image is configured, the platform sharing the link may pick a random image from the article or display no image at all, which can result in poor-looking previews on social media.

It is recommended to set a default featured image for your project.

Best practices

• Use article-specific images. Choose an image that represents the article topic clearly. A relevant screenshot or product image communicates context better than a generic stock photo.
• Maintain consistent dimensions. Stick to the recommended 1,200×800 px minimum to ensure the thumbnail displays correctly across platforms and screen sizes.
• Set a project-wide default. Configure a default featured image at the project level so articles without a specific image still display something relevant when shared.
• Refresh cached previews after updating. Social media platforms cache Open Graph images when a link is first shared. After updating a featured image, use the platform's URL debugger tool such as Facebook's Sharing Debugger or LinkedIn's Post Inspector to force a preview refresh.
