How does social sharing and Open Graph work in VeloCMS?

VeloCMS generates Open Graph (og:) and Twitter Card meta tags automatically for every published post using your post's title, excerpt, featured image, and author data — you don't need to configure anything for basic social sharing to work. When someone shares your link on LinkedIn, Twitter/X, Slack, or Facebook, the platform reads these tags and renders a rich preview card with your image and headline.

Which Open Graph tags does VeloCMS generate?

Every post page includes og:title (your SEO title, or the post title), og:description (your meta description, or the post excerpt), og:url (the canonical URL), og:type (set to 'article' with the publish time), og:site_name (your blog name), and og:image. For Twitter/X, VeloCMS sets twitter:card to summary_large_image, and Twitter reads the title, description, and image from the og: tags — so one set of tags covers every platform.

What image does VeloCMS use for the social preview card?

The og:image is resolved in a fixed cascade. If the Auto OG Image plugin is enabled (Admin → Plugins), every post gets a generated 1200×630 card rendered from the post title — this takes first priority. Otherwise VeloCMS uses the post's featured image; if the post has none, it falls back to your site logo, and finally to a platform default image, so a share card always has some artwork. The generated-card plugin has three settings: the background style (gradient or solid), whether to show the post's first tag as a chip, and whether to include your blog name under the title. For best results with your own featured images, use an image at least 1200 pixels wide — the wide 1200×630 format is what most platforms crop to.

Can I override the social title or image for a specific post?

What you control per post is exactly what the card is built from: the og:title comes from the post's SEO title field (or the post title when that's empty), the og:description comes from the meta description field (or the excerpt), and the og:image comes from the featured image. There are no separate social-only title, description, or image fields — editing the SEO title and meta description in the post editor's SEO panel changes both search and social metadata together. If you want a consistent branded card on every post regardless of featured images, enable the Auto OG Image plugin instead.

Why does Facebook or LinkedIn still show the old image after I updated it?

Social platforms aggressively cache Open Graph data. If you update a post's featured image or title, the new og:image or og:title won't appear in shares until the platform's cache expires (typically 24–48 hours) or you force a re-scrape. Facebook has a Sharing Debugger at developers.facebook.com/tools/debug that lets you paste your URL and force a cache refresh. LinkedIn has a similar Post Inspector at linkedin.com/post-inspector. Twitter/X refreshes cards more quickly — usually within a few hours — but doesn't offer a manual flush tool. If urgency matters, the fastest approach is changing the post's slug (which creates a new URL that the platforms haven't cached yet) and setting up a redirect from the old slug.
