Frequently asked questions
Why does my link show a small card with no image?+
The page is missing an og:image (and twitter:image). Add a 1200×630 image tag to get the large card.
Does this clear the platform’s cache?+
No. Facebook, LinkedIn and X cache scrapes — use their own debuggers to force a refresh after you update tags.
Can it fetch tags from any URL?+
Most public pages, yes, via this app’s server. Pages that block bots may not return their meta tags.
Is the URL stored?+
No. It is fetched once to read the meta tags.
