See how your link looks when shared on Facebook, X, LinkedIn or WhatsApp.
Wrong or old image when sharing?
You did everything right — og:title, og:description and og:image are correct — yet Facebook or WhatsApp still shows an old or wrong image? It is almost always the cache: platforms store the preview the first time a link is shared and do not refetch it automatically. If you change the image or title afterwards, everyone keeps seeing the old version. Fix: open the platform's official debugger, enter your URL and let it re-read the preview (the button is usually called Scrape Again). After that the cache is fresh. Alternatively, append a small suffix to the URL (e.g. ?v=2) — the platform then treats it as a new page with a fresh preview.
Official debuggers & clearing the cache
Use these official tools to check the preview directly at the platform and force a refetch:
X (Twitter): the former Card Validator was shut down. X reads the same og:/twitter: tags — just share the link again to refresh the preview.
WhatsApp: has no own debugger and partly uses Facebook's cache — so the Facebook debugger above often helps. Otherwise change the URL slightly (?v=2).
