Metadata that supporting services can use to represent a shared page with a title, image, description and URL.
Open Graph tags describe a page for services that consume the Open Graph protocol. Common properties identify the title, content type, representative image and page URL. A description can provide additional context. These fields are metadata about the page, not extra paragraphs added to its visible body.
A useful social preview should represent the specific destination rather than show the same generic information for every link. The metadata can identify an article, product or other page, but the consuming platform decides how it presents the information. Adding tags does not guarantee that every app will display the same image, wording or layout.
Keep the preview honest and consistent with the destination. Open Graph metadata does not create a verified rating, a special endorsement or a search ranking advantage. If a preview image includes a claim about a product or service, that claim needs the same support as visible website copy. Avoid treating metadata as a place where unsupported marketing statements are harmless.
Takeaway: Choose a recognizable image and accurate title for pages people are likely to share. Check the actual destination and preview rather than assuming a sitewide logo is the right image for every page.
Example
A workshop organizer shares a page about a pottery class, but the preview uses a generic image from an unrelated course. The team checks the page’s image metadata and selects a relevant class photograph. It does not add review stars to the image merely to make the preview look more authoritative.
What to check
Check the emitted metadata and whether the referenced image can be retrieved. Keep the Open Graph page URL consistent with the intended destination. A preview check in one app is evidence for that app, not proof of identical behavior across all sharing services.
