What This Tool Does
Enter a URL and the page is fetched and scanned for its Open Graph and Twitter Card tags, plus the page title, meta description, canonical link and favicon. Every og and twitter tag found is listed, not only the ones the previews happen to use.
Eight cards are built from those tags: Facebook, Twitter as both a small summary and a large image card, LinkedIn, Discord, Slack, WhatsApp and iMessage. Each one truncates the title and description the way that platform does, so you can see which of them will cut your headline off.
A score out of 100 weights the tags by how much they actually affect a share. The image counts for 20, title and description for 15 each, the URL for 10, and the rest for less. Every line tells you what was found and what to change.
Limits Worth Knowing
- Fetching is rate limited to ten checks a minute and gives up on a slow page after ten seconds.
- Only the beginning of a large page is scanned, and tags added by scripts after the page loads are not visible to the check.
- The cards are reconstructions, not screenshots from the platforms. A platform that already cached your page keeps showing its old card until it refetches.
- Image dimensions are measured by loading the image in your own browser, so an image that is blocked or very slow shows as unmeasurable rather than missing.
- Manual Input mode lets you type tag values and preview them before they exist on a live page at all.
