Search-led performance marketing for growth brands in B2B and consumer sectors

Passion Digital is a performance marketing agency in Holborn, London, that puts search at the centre of its work. Organic and paid search sit side by side, supported by content, digital PR and paid social, so that campaigns are planned across the whole journey from discovery to conversion.

On the organic side the team handles technical, content and international SEO, along with audits and site migrations. It also works on visibility in AI-generated answers, treating generative engines as another place where brands need to show up. Paid work covers Google and Microsoft Ads, social platforms, programmatic display and retail media, with conversion rate optimisation and analytics tying the channels together.

The agency serves B2B firms, professional services, travel companies, charities and ecommerce brands. It aims to act as an extension of each client's in-house team over the long term. Passion Digital is now part of Stellar, a performance network backed by Pixis, while keeping its own London team.
