M21 Consultancy is a full-service digital agency built exclusively for ambitious London SMEs. Website, SEO, paid media, brand, social, and email — all under one roof, driven by one strategy.
Five years serving London's SME community. We don't pitch retainers and disappear — we embed ourselves in your business, learn your market, and build a digital presence that genuinely moves the needle.
We work only with small and medium businesses in and around London. We understand this market — the competition, the search intent, the neighbourhoods — and exactly what it takes to stand out in one of the world's most competitive cities.
No juggling five separate agencies or contractors. M21 handles your website, SEO, paid media, brand identity, social, and email — all coordinated by a single account manager who knows your business inside out.
We don't sell services for the sake of billing. Every engagement starts with a thorough audit and a clear commercial strategy — then we execute against it with discipline, and report on what actually matters.
Every campaign and every ranking is tracked and tied directly to revenue impact. Monthly reporting is clear, honest, and written in plain English — you'll always know exactly what you're getting and what it's worth.
A complete digital stack — from first impression to final conversion. Each service can be taken individually or combined into a fully managed growth programme tailored to your budget and ambitions.
Custom-built websites engineered to convert visitors into leads. Fast, mobile-first, and built around your customer journey — not a template. From landing pages to full e-commerce stores.
Rank higher, stay there. Technical SEO, on-page optimisation, local search dominance, content strategy, and link acquisition — with monthly reporting you can actually read and trust.
Google Search, Shopping, Display, and Meta campaigns managed end-to-end. Strategy, creative, targeting, bidding optimisation, and weekly performance reviews with clear ROAS reporting.
Logo, typography, colour system, and comprehensive brand guidelines that work across every touchpoint — digital and physical. Built to position you exactly where you want to be in your market.
Content calendar, copywriting, graphic production, scheduling, and community management across Instagram, LinkedIn, Facebook, and TikTok. Consistent, on-brand, every single week.
Strategy, design, copywriting, automation flows, and list management. Welcome sequences, promotional campaigns, and abandoned cart recovery — your list is an asset; we make it work.
GA4 setup, full conversion tracking, heatmaps, A/B testing, and ongoing CRO audits. Turn more of your existing traffic into enquiries and sales — more revenue without more ad spend.
Blog posts, web copy, case studies, and video scripts written to rank, convert, and position you as the authority in your sector. Content that compounds in value long after it's published.
Real outcomes for real London businesses. Every figure is tracked, verified, and tied directly to commercial outcomes — not traffic vanity metrics.
Every engagement follows a structured path from audit to growth. No guesswork, no vanity metrics — just a clear strategy executed with discipline and reported honestly.
We audit your website, existing rankings, ad accounts, and social presence. We map your competitors and identify the specific gaps and opportunities in your market before recommending a single thing.
A clear, prioritised plan tied to your revenue goals — which channels, in what order, with what budget. You see the full roadmap and sign off before a single pound is spent.
Each discipline delivered by the relevant specialist. Your account manager coordinates everything. No generalists, no juniors running your campaigns — senior-level execution across every service.
Clear, honest reports on every KPI that matters to your business — traffic, leads, ROAS, rankings. Monthly calls to review results, adjust the strategy, and plan ahead.
As results build, we identify the next layer of growth — new channels, new campaigns, new content angles. The strategy evolves continuously. We're built for long partnerships, not one-off projects.
We'd been burned by two agencies before M21. The difference is they actually understand our business — they're not just running ads, they're thinking strategically about where we're going.
Our website was invisible on Google. Within four months of working with M21 we're on page one for every term that matters to our practice. The phone genuinely hasn't stopped.
I can finally see clearly what I'm spending and what I'm getting back. The reporting is clear, the results are real, and they respond the same day. Exactly what a growing business needs.
For M21 clients who want every inbound call answered professionally — even outside business hours. Our virtual receptionist service handles calls, qualifies enquiries, and books appointments, all branded to your business.
