Case Study: Three achieves 148K campaign engagements and 25% lower CPA with Outbrain Amplify

How Three drove consumer sign-ups for their online petition ‘make the air fair’ campaign

Mobile provider Three ran the “Make the Air Fair” campaign to urge Ofcom to impose a 30% cap on airwave ownership. The goal was to educate consumers about how spectrum concentration affects price and service, drive traffic and engagement, and secure petition sign-ups in a limited timeframe.

Three used Outbrain Amplify’s discovery and earned-media placements to amplify campaign content. Outbrain outperformed other channels, delivering 148K engagements and a cost per acquisition 25% below the target, making it the campaign’s most successful and cost-effective channel.
