Social cards

Control how your event appears when shared on social media — title, description, and keywords — from the Website tab's Settings sub-tab. Open Graph image upload is not yet available in the UI, so social shares currently render without a preview image.

Updated May 26, 2026

When someone shares your event URL on Slack, LinkedIn, Twitter, or any platform that reads Open Graph tags, the social card draws from your SEO settings. You control the title, description, and keywords from the event editor. An Open Graph image field exists in the data model but has no upload UI today — social shares render without a preview image unless the field is set directly.

Where to edit

Open your event and go to the Website tab (/{slug}?tab=website). Click the Settings sub-tab. The SEO section is in that panel.

What you can customize today

Three text fields are exposed in the SEO section:

  • SEO title — overrides the event title in search results and social card headlines. Leave blank to use the event title.
  • SEO description — the text that appears below the title in search previews and social card subtitles. Aim for 150–160 characters. If blank, Mercleo Events falls back to the event description, then to "Register for [title] — [organization name]".
  • SEO keywords — comma-separated terms added to the page's <meta name="keywords"> tag. Most search engines treat this field as a weak signal today, but it is included for completeness.

Open Graph image

A dedicated OG image field (seo_image_url) exists in the database and the server action accepts it, but no upload UI is wired up in the event editor today. The three text fields above are the only SEO controls currently exposed.

Social previews currently render without a preview image. When seo_image_url is null, the openGraph.images key is omitted from the page metadata entirely. The cover image is not used as an automatic OG image fallback. Open Graph image upload will be added to the Settings sub-tab in a future release.

Twitter card tags are not explicitly set. Platforms that fall back to Open Graph will read the title and description but also show no image for the same reason.
