An SEO Agency in London Built for Long-Term Growth
We work with a small number of London businesses on long-term SEO retainers — building inbound lead systems that compound over months and years, not campaigns that spike and fade.
Why London Businesses Choose BCS
London is the most competitive search market in the UK. Generic SEO doesn't move the needle here — what works is depth: hundreds of targeted landing pages, a strong technical foundation, and a clear strategy for the queries that actually convert in your sector.
We focus exclusively on retainer relationships with businesses that are serious about growth. That means fewer clients, more attention per client, and a system that gets stronger every month.
Our Approach to London SEO
We start with discovery — your sector, your competitors, your highest-value services, and the specific London neighbourhoods or boroughs your customers come from. From there we build a programmatic landing page system covering every realistic service-and-location query worth ranking for.
Underneath that we handle technical SEO, site speed, schema, internal linking, Google Business Profile, and ongoing content. Every page strengthens the next.
Who This Is For
This is the right fit for London businesses with strong unit economics — typically B2B services, professional services, premium consumer brands, and high-value local services — who want a long-term partner rather than a quarterly project.
If you're looking for a one-off audit or a short campaign, we're not the right fit and we'll tell you so on the first call.
Frequently Asked Questions
Do you only work with London-based businesses?
No — we work with clients across the UK. This page exists because a lot of our enquiries come from London businesses specifically.
What size of business do you typically work with?
Most of our clients are between £1m and £20m turnover with the ambition and infrastructure to grow significantly over the next few years.
How is your retainer structured?
Monthly retainer, minimum 6-month engagement to allow the work to compound. Full pricing is on our pricing page.
Do you offer one-off SEO audits?
No. We only take on long-term retainer clients. One-off audits don't produce the outcomes we want to be associated with.
