A question you shared as a link gives you the same result page as any other question. Three things read differently, on purpose.
The caveat
Every result from a link ends with the same sentence: These are the people who chose to answer. The result may not reflect those who didn't. Heads are chosen by 50heads and verified; your audience chose themselves. A strong lead among the people who answered is still a strong lead among them, but it says nothing about the people who ignored the link.
No tier, no verification reference
A heads result shows the tier and, on every answer, a reference showing the device and app check passed. A link result shows Your audience · shared link and Not verified by 50heads instead, and no answer carries a reference, because nobody was checked. For the same reason, answers from a link cannot be flagged or disputed: there is no head behind them to review.
No response rate yet
A result from heads says "50 of 50 answered". A link result says how many answered, and the maximum you allowed, but not how many people saw the link, because 50heads did not send it and does not know how many people you reached. Page views are shown on the question page as a rough guide.
Breakdowns
A link knows nothing about the people who answered beyond the language their page was in, so the only breakdown is by language, and only when at least five people answered in a language. There is no breakdown by tier, country or tag.
Exports and sharing
The CSV has two extra columns, answered_by and access, reading private and shared_link on every row, and a note at the end that the answers were not verified by 50heads. The PDF report and the PNG card carry the same line in their footer. A public result page or a private share link says "your audience · shared link · not verified by 50heads" in place of the tier, with your Shown as name when you set one.
Comparing with heads
To see how verified people answer the same question, open the question and choose Ask heads the same question. It opens the composer with the question filled in. The two results stay separate; nothing from a link is ever mixed into a heads result.
