Check Open Graph and meta tags
Inspect the HTML metadata a search engine or social preview can see — including canonical, robots, OG, and Twitter card fields.
| Field | Value |

The metadata behind every shared link
Open Graph tags control how a page appears in many messaging and social apps. A strong card needs a specific title, a useful description, an absolute image URL, and a canonical destination. Twitter card tags can override the same fields for X.
Metadata and redirects belong together
If the checked URL moved, inspect the full path with the redirect chain checker. When sharing the final URL, the URL cleaner removes unnecessary attribution parameters.
Frequently asked questions
Which tags does the checker inspect?
It reads the HTML title, meta description, canonical link, robots directive, Open Graph title/description/image/url/type/site name, and Twitter card/title/description/image.
Why can the preview differ from a social network?
Platforms cache metadata and apply their own layouts, image crops, and fallbacks. This preview shows what the current HTML declares, not an individual network’s cached copy.
Does this render JavaScript?
No. It inspects the initial HTML response. Metadata generated only after client-side JavaScript runs may not appear, which is also a warning sign for many crawlers and link unfurlers.
Can it inspect private URLs?
No. The checker only requests public HTTP or HTTPS pages on standard ports and blocks local/private addresses and unsafe redirect targets.
