A boutique South London digital marketing agency. A senior craft.
With over 10 years of senior experience, OM Marketing is a digital marketing agency in South London — proudly serving Croydon, Sutton, Mitcham, Wallington, Morden, Fulham and all of London with measurable SEO, paid media, social, email, content and website results.
We are a South London–based boutique digital marketing agency built around a simple idea: marketing works better when it is led by people who have actually done it — at scale, across disciplines, for the kinds of brands you'd recognise.
Based in South London and serving Croydon, Sutton, Mitcham, Wallington, Morden, Fulham and all of London, our craft has been shaped across the charity, healthcare, non-profit and commercial sectors — from major fundraising moments to performance-led B2B and consumer growth.
We work as an extension of your team. Strategy, paid media, social, SEO, email, content and website design are joined-up under one roof, so nothing falls between the cracks and every pound spent compounds toward growth.
Whether you're a local business in Croydon or Sutton looking for stronger local SEO, or a London-wide brand that needs an AI-enabled, senior-led digital marketing partner — we select our clients carefully and make every effort to ensure each one feels like they are our only client.

A calm, considered four-step process.
No noisy onboarding. No 60-page decks. Just four clear stages designed to get to measurable growth — fast.
Discovery Call
A relaxed, no-pressure conversation about your business, your audience, and where you want to go.
Strategy & Audit
We audit your current marketing and produce a clear strategy — including our SEO Keyword Universe Report to map every opportunity.
Build & Launch
Channels, creative, campaigns and (if needed) a new website — built and launched with senior craft, not delegated to juniors.
Optimise & Grow
Weekly and monthly review cycles, transparent reporting, and continuous optimisation tied to the metrics that matter to you.
Numbers that matter. Quotes that mean something.
A snapshot of outcomes from partnerships across charity, healthcare and commercial brands.
Senior, strategic and genuinely hands-on. Spearheaded the marketing function from the ground up and delivered the kind of growth we needed to scale with confidence.
Sharp instincts on paid social and content, with the discipline to back it up with measurement. A safe pair of hands when the stakes are high.
