Burger King’s “Whopper Detour”: Revolutionizing Mobile Marketing

In the fast-food wars, few campaigns have made as bold—or as brilliantly cheeky—a move as Burger King’s “Whopper Detour.” This marketing stunt wasn’t just clever; it was a masterclass in mobile strategy, geofencing technology, and viral buzz. By turning their competitor’s locations into a digital playground, Burger King didn’t just sell more burgers—they completely changed the conversation around mobile app marketing.

Let’s break down how this campaign worked, why it was so effective, and what businesses can learn from this mobile marketing milestone.

📲 What Was the “Whopper Detour”?

Launched in December 2018, the “Whopper Detour” was a limited-time promotion where customers could unlock a Whopper for just 1 cent—but there was a twist: they had to be within 600 feet of a McDonald’s to redeem it.

Yes, you read that right.

Burger King literally geofenced 14,000+ McDonald’s locations across the U.S., turning their most significant rival’s restaurants into the trigger point for activating a Burger King deal. To redeem the offer, users had to:

1. Download or open the Burger King app

2. Be physically near a McDonald’s location

3. Unlock the deal and be redirected to the nearest Burger King to claim it

This brilliant move not only trolled the competition, but it also forced users to engage with the app, activate location services, and physically visit Burger King—driving mobile installs and in-store traffic at once.

🧠 Why It Worked: Marketing Genius in Motion

✅ 1. Savvy Use of Geofencing

The core of this campaign was its geolocation technology. Burger King utilized geofencing to create a virtual boundary around each McDonald’s, gamifying proximity and making location an integral part of the experience.

✅ 2. Massive Mobile App Boost

In just 9 days, the Burger King app hit the #1 spot in the App Store, with over 1.5 million downloads. That’s a massive win for a fast-food app and helped Burger King build a long-term mobile customer base.

✅ 3. Viral Word-of-Mouth

People love a clever underdog story—and the media ate this up. It was featured everywhere, from CNN to Forbes to AdAge, transforming a stunt into millions of earned media value. Consumers shared their experiences, screenshots, and stories online, turning the campaign into a social media sensation.

✅ 4. It Was Funny and On-Brand

Burger King’s brand is known for irreverent, playful jabs at the competition, and this was no exception. The Whopper Detour stayed true to that tone while executing with sophistication.

🔍 Campaign Results

• 1.5 million+ app downloads

• App Store’s #1 trending app during the campaign

• 3.5 billion earned media impressions
