How each social platform processes Link Preview

If you prefer not to display link previews and would rather use an image of your choice, you have the option to attach an image instead.

When you do this, the image you attach will take precedence over the link preview, resulting in a published post that includes both the link and a separate, user-selected image.

Facebook.

Facebook generates and displays link previews by utilizing a process known as web scraping, specifically designed to extract and display relevant information from web pages when users share links in their posts. If a link doesn't generate a suitable preview, users can often manually edit the preview by selecting a different image, changing the title or description.

X (Twitter).

Link previews in Twitter tweets are shown exclusively for websites that have Twitter Cards enabled. To confirm whether the website you're linking to has a Twitter Card, simply input the link into Twitter's Card validator tool.

To ensure your tweet includes an image, you have the option to either upload your own image or choose from the suggested images extracted from the linked content. If you decide to attach an image, it will take precedence over the default preview, even if the link contains a Twitter Card. Consequently, the final tweet will comprise a clickable link and a separately uploaded image.

LinkedIn.

LinkedIn does display link previews when you include a link in a post or article. These link previews typically include a title, description, and thumbnail image extracted from the webpage you're linking to. The purpose of these previews is to provide context and a visual representation of the linked content to your audience.

Please note that LinkedIn's features and interface may change over time, so it's a good idea to check LinkedIn's official help center or documentation for the most up-to-date information on how link previews work on the platform.
