    Why a preview does not burn a secret

    A link unfurler fetches the page shell and gets the title and status only. The secret is fetched, and the view counted, when the page runs in a browser.

    What are Open Graph tags?

    Open Graph is a metadata protocol that controls how URLs appear when shared on Facebook, LinkedIn, Slack, iMessage, and most modern platforms.

    Twitter has its own twitter:card variants that fall back to Open Graph if not specified.

    If the card looks wrong, the cause is usually the page's tags or a redirect in front of it. Fix Open Graph link previews walks through the tags each platform reads, the redirect checker shows whether a scraper is bounced through hops before it reaches your page, and the link trust score tells you whether the destination itself is flagged. For the vocabulary (og:image, canonical, unfurl) see the glossary. The plain-English link preview checker shows the finished card for eight platforms at once.
