After you've saved your landing page, you can change how the link will appear on social media.
In technical terms, this is called an "og:image" which is a part of the Open Graph protocol used by most social media sites
- Open your landing page
- You'll see the sharing preview. You can edit the page image, title and description:
The title can be up to 55 characters and the description up to 147.
Until you edit the preview, the title is the landing page's name and the description and image are taken from the page content. Once you edit it, your title, description and image are kept even if you change the page later. To fetch the title and description from the page again, click Reset info. The image you chose is kept.
