Mobile quiz funnel

A product quiz for visitors from Instagram ads that recommends a bundle and captures the lead before the result.

The problem

Paid social traffic lands on phones and leaves quickly. A short quiz keeps them engaged and turns answers into a qualified lead.

What I built

• Eight to ten questions with branching and a progress bar that stays correct when the path changes.
• Lead step with separate, unticked marketing opt-ins and a typo check on email domains.
• Result worked out on the server: a personal bundle, its price and the reasons; one tap adds it to the cart.
• Leads stored in WordPress with campaign source, CSV export and GDPR export/erase.

How it was tested

• 7 PHP unit tests and 9 JavaScript unit tests.
• 21 integration tests on WordPress 7.1 with PHP 8.3 and on WordPress 6.4 with PHP 7.4.
• 11 browser tests on a phone-sized screen.
