Listen a Sound & Guess a Number - Lead Gen - Hearing Test

The challenge with this creative was to make a lead generation banner ad which collects a person's phone number for a free hearing test.

Тhis amazing and complicated HTML5 ad wins users' attention with a quick sound test - user can click to hear a sound and then guess a number. Once clicked, the second slide with a lead form is revealed. Users can leave their phone number if they want to be invited to a free professional hearing test in one of the advertiser's offices. All leads (phone numbers) are collected in a Google Sheet file, so the advertiser's call center can access and process the data instantly. Curious about the data behind the campaign? 25% of the users chose the wrong number (failed on the sound-test) and 2% of all interacted users signed up for the professional offline test.
