A shared link preview is assembled from metadata a page supplies, such as an image, title, description and URL. Those fields can be published as separate metadata, distinct from the page's visible content. A picture in a card is therefore supplied presentation context, not independent evidence that the person shown operates the site behind the link. Open the actual destination, read its host, heading and body against the card, and treat any mismatch as a question rather than a verdict.

Start with what the card actually is
A link-preview card is presentation data. A webpage can publish a preview title, image, URL and description as separate metadata fields. The picture on a card is supplied context; it is not a signature and not independent identity evidence for the person shown. [Open Graph protocol: page-selected preview metadata]
- Note the four card elements separately: picture, title, description, destination.
- Say to yourself: the picture is supplied context, not identity.
Read the destination, not the label
Every link resolves to a specific address, and an address separates scheme, host, path, optional query parameters and fragment. The label you see on a card is not the same object as the target address it points to. Similar-looking addresses are not automatically identical, and trimming query parameters can break the page because servers handle them by their own rules. Read the host and path of the actual destination shown. [MDN: URL components]
- Open the destination directly and note the host and path.
- Do not delete query parameters just to test; they may be required.
Compare the picture and title against the page body
Once the destination is open, read its heading, main text and any about or contact material. Ask whether the card's image and title are explained anywhere on the page, and whether the page's own words match what the card promised. Keep the observation (card and page differ) apart from the conclusion (the site is or is not legitimate).
- Write one line: what the card showed, and what the page shows.
- Leave the identity question open until the page itself speaks to it.
Hold the familiar face to the right standard
A recognizable face in a preview is not a verified badge, a location, a status or an endorsement. Do not treat a photo, a matching image, a privacy setting or a username as proof of identity, intent or safety, and do not use it to justify contacting strangers or third parties. If someone you know appears on a card, the useful question is whether the destination explains that appearance, not whether the person endorses the link.
- Do not identify people from the image alone.
- Do not forward the card onward as if the face vouched for the link.
A small worksheet for one shared card
Keep the card and live page as separate observations. If the destination will not load or the page is gated, record that limitation instead of substituting the preview for content you could not read.
| observation | limit | next step |
|---|---|---|
| Card picture shows a face | The image is a page-supplied preview field; identity is not established | Open the destination and look for the page's own authorship or about text |
| Card title is short and punchy | A preview title is one supplied metadata field, not a summary of the page | Compare against the page's visible heading and body |
| Destination address looks familiar | A displayed label is not the target address | Read the host and path of the actual destination |
| Page content is behind a gate | Content not visible from here | Record unavailable and stop at that boundary |
A couple more questions
The card shows a photo of someone I know. Does that mean they own the website?
No. A link-preview picture is supplied metadata, separate from another page's title, description and destination, so a recognizable face is not independent evidence that the person shown operates the linked site. Open the destination and look for the page's own authorship or about information before drawing any conclusion.
The preview title does not match the page headline. Is the link fake?
Not necessarily. Preview titles and images are supplied metadata and can differ from the page's visible words. Treat the mismatch as an observation, then read the destination's host, path and body directly. A difference alone is not proof of anything.
The link will not open on my device. What should I record?
Record unavailable and stop at that access boundary rather than guessing what the page contains. Ask for a voluntary current link you can open yourself. Do not substitute the preview's picture or title for the page content you could not see.
