Because in-feed links are not tappable, Duolingo measured viral impact with a "How did you hear about us?" onboarding field and shifted its KPI from press and impressions to real new-user counts.

The steal: when the platform will not give you a clickable link, build the attribution yourself — one "How did you hear about us?" field at intake. Duolingo's social lead put it plainly: whenever they have a viral video, they see an uptick in new users. That single question turns vanity views into a number you can take to the bank.

My Stash Take. Views are vanity until someone tells you the panda is why they showed up. Add the one line to the Stash Room intake and the day a video pops, you will see it in the funnel instead of guessing. It is the cheapest piece of measurement you will ever build, and the only one that ties a laugh to an invoice.

What to watch. Watch the intake answers the week after any video spikes — that is your real reach number, not the view counter.

Sourced from The Drum. This is a Stash Edge Homework Edition play — drawn from adversarially verified 2025-26 short-form video research, rebuilt into a play you can run this week.

## The takeaway

when the platform will not give you a clickable link, build the attribution yourself — one "How did you hear about us?" field at intake. Duolingo's social lead put it plainly: whenever they have a viral video, they see an uptick in new users. That single question turns vanity views into a number you can take to the bank.
