Social cards
A social card is an image that the wiki makes for each page. Chat apps and social networks show it when someone shares a link to the page. The wiki uses it when the page has no meta image.
What the card shows
The card is 1200 × 630 pixels, in JPEG format. It always has a light background. It shows, from top to bottom:
- The space logo or the space icon.
- The groups above the page, up to two levels. If the page is deeper, the trail starts with
…. - The page title. Long titles use a smaller font and stop after three lines.
- The space name.
The card uses the page title, not the meta title. The layout and the colors can't be changed.
Use your own image
Upload a Meta image in Page settings. Your image always replaces the social card on that page. See Meta title, description and image.
In Page settings, the Preview shows the social card when the page has no meta image. The text under it says that the image is generated.
Turn social cards off
- Open Wiki settings.
- In General, turn off Auto Generate Meta Images.
Pages without a meta image then have no image tags.
Privacy
A card follows the permissions of its page. For a page in a private space, or an unpublished page, the card URL returns "not found" to a person who cannot read the page.
