Description: What Open Graph tags are and how Xodia sets them: a share title, description and image for every page, written into the page's own HTML for link previews.
Last updated: 2026-11-08

Open Graph is a set of meta tags, such as og:title, og:description and og:image, that decides the title, text and picture shown when a page is shared in social media and chats.

How Xodia sets Open Graph tags: each page's settings hold its share title, description and image, the same as its title tag and meta description until you change them, and prerendered pages carry them in their HTML so link previews find them.

## What it is

When someone pastes a link, the app fetches the page and reads its Open Graph tags to draw a card. Without them it guesses, often with the wrong image or no text at all.

The share image works best at least 1200 by 630 pixels, and the tags must be in the page's HTML, since most link previews don't run JavaScript.

## In Xodia

A page's settings have the Open Graph title, description and image, each Same as the title tag and meta description unless you change it. On a CMS collection page they are templates, with the share image taken from an image field, and a share preview that steps through your items.

Collection pages are prerendered, so each item's own share tags are in its HTML for link previews.
