How challenge links work
A challenge link is more than a copied URL
It packages summary result data into the landing-page context so the next visitor does not start from zero.
Why this matters for virality
A plain share says, 'look at my result.' A challenge link says, 'beat this.' The second prompt is much stronger for engagement and response.
What it changes in the experience
It changes the call to action, the landing-page framing, and the expectation for what happens after finishing the quiz.
