5 Star Agency

Full-funnel London growth

London is a crowded market with high ad competition and audiences split across platforms. A strong marketing agency London businesses hire should not just run channels, but run the system: acquisition, conversion, and retention measured against unit economics. We start with a funnel and measurement audit, align on north star metrics and stage KPIs, then run weekly sprints across paid, SEO, CRO and lifecycle. This keeps learning fast and budget focused on the highest-leverage constraints.

Funnel audit and priorities

Map acquisition to activation to revenue, then identify the main constraint so your spend and effort go to the work that will move results fastest.

Weekly sprint execution

Ship improvements every week across creative, campaigns and conversion assets, so learnings compound and you avoid slow monthly iteration cycles.

Measurement linked to revenue

Align tracking and KPIs to pipeline, CAC payback and LTV, so decisions are based on outcomes rather than channel-level vanity metrics.

Get a roadmap

From activity to outcomes

Many London agencies deliver busy work: posts, campaigns and reports that do not connect to revenue. The result is lots of motion, slow learning, and budget drifting into what is easy to run rather than what moves the funnel. We operate with one measurable plan. Every sprint ties back to your north star metric and stage KPIs, and we prioritise the work that removes the biggest constraint first. This turns marketing into an operating system, not a collection of channel tasks.
  • KPIs tied to revenue
  • One backlog across funnel
  • Less waste, faster learning

Paid media and creative

Paid performance in London is increasingly creative-led. We run paid search and paid social across Google, Meta, TikTok, LinkedIn and Snap where it fits your ICP, offer and conversion path. Creative is treated as a growth lever: we test angles, proof and offers weekly, scale what works, and refresh to prevent fatigue. Unlimited ad creative production is included, and we charge no commission on ad spend, keeping incentives aligned to profitable growth rather than budget size.

Creative testing system

Run weekly testing across hooks, proof points and formats, then scale winners with a clear learning loop and continuous refresh to beat creative fatigue.

Platform mix by intent

Choose channels based on user intent and unit economics, not trends, then build structures that keep prospecting and retargeting results interpretable.

Landing page message match

Align ad promises to page content and next steps, so conversion improves and you do not have to buy more clicks to hit growth targets.

Scale paid growth

SEO, CRO, and lifecycle

In London, sustainable growth needs more than paid. We strengthen technical SEO and build intent-led content that supports evaluation, alongside digital PR where it fits. We then apply CRO to increase conversion on key journeys using analytics, heatmaps and structured experiments. Finally, we build lifecycle marketing through nurture and retention programmes so value compounds after the first conversion. This reduces reliance on volatile auctions and improves payback, especially for B2B, e-commerce and subscription models.

Technical SEO foundations

Fix site structure, Core Web Vitals and indexing, then build topic clusters mapped to intent so organic demand grows and supports revenue outcomes.

CRO on key pages

Test friction, messaging and proof on landing, pricing and checkout or demo flows, improving conversion without a full site redesign.

Lifecycle retention programmes

Build onboarding, nurture and win-back flows triggered by behaviour, so you increase LTV and reduce the need to constantly buy new customers.

Build compounding growth

Speed without lock-in

Hiring in London is slow and expensive, and multi-agency setups create handoffs that kill momentum. When you need growth, you cannot wait for perfect resourcing or six-month contracts to end. We move quickly with a team that integrates like internal staff, scales up or down as bottlenecks change, and works on a monthly rolling basis. That gives you the speed of a specialist unit without the risk and overhead of building everything in-house.
  • Monthly rolling engagement
  • Scale specialists on demand
  • Faster than in-house hiring

SEO that compounds, not a checklist

Organic growth is a mix of technical hygiene, content that earns clicks, and authority building that is genuinely deserved. We treat SEO as a product, with a backlog and a cadence, rather than a one-off project. Technical work covers crawlability, site architecture, Core Web Vitals, schema markup and index management. On-page work is driven by search intent and the real questions buyers ask at each stage. Off-page focuses on link earning through useful assets, partnerships and digital PR rather than spam. For example, for a B2B brand we might build a set of comparison pages for demand capture, a small research piece to earn links, and a library of problem-led articles that support sales calls. The outcome is more qualified traffic, better brand credibility, and lower dependency on paid media over time.

What should a marketing agency London engagement include?
A strong London marketing partner should cover the full funnel: acquisition, conversion, and retention. That usually means paid media and creative, SEO and content, CRO on key journeys, and lifecycle nurture through email or CRM. If an agency only runs channels, you often end up paying twice to fix performance later. Look for teams that can improve what happens after the click, and measure success against pipeline, revenue and customer value.
How do you choose between brand-led and performance-led agencies?
It depends on your goal and stage. If you are building awareness and positioning, brand work can be valuable. If you need efficient growth, you need performance plus conversion and retention, not only ads. A practical approach is to align on one north star metric, then pick the mix of creative, channels and conversion work that will move it. We focus on measurable outcomes while keeping creative strong and on-brand.
Do you manage paid social and PPC for London businesses?
Yes. We manage paid social and paid search across Google and Meta, and can extend to TikTok, LinkedIn and Snap when it matches your audience and economics. The focus is not only media buying. We build a creative testing cadence and landing page message match so conversion improves. With no commission on ad spend, our incentives are aligned to payback and profit, not budget size.
Can you support WhatsApp and conversational lead qualification flows?
Yes, where it fits the customer journey. For some London audiences and sectors, conversational flows can reduce friction and improve speed-to-lead, especially when paired with clear routing and follow-up. We treat this as part of the funnel, not a standalone tool. The key is tracking: message initiation, qualification steps, handoff to sales, and downstream conversion. That way you can measure whether it is improving lead quality and revenue.
How do you report results and prove marketing impact?
We align on KPIs that reflect business outcomes, then report in a way that supports decisions. You get a real-time performance dashboard plus weekly updates showing what changed, what it impacted, and what we will do next. Where attribution is noisy, we use practical checks like controlled tests and trend analysis. The goal is to reduce guesswork and make budget decisions with confidence.
What does the first month with you look like?
We start with a funnel and measurement audit, then align on your ICP, offer, and north star metric. From there we build a prioritised backlog and begin shipping improvements weekly. In the first month you should expect early work across creative testing, campaign structure, landing page conversion fixes and lifecycle basics. You will see what shipped and what was learned, not a vague month-end summary.
Do you work with B2B SaaS, e-commerce, and service businesses?
Yes, and the approach changes by funnel and sales motion. B2B SaaS often needs pipeline quality, nurture and sales enablement. E-commerce and subscriptions need creative velocity, CRO and retention. We start by identifying your bottleneck and unit economics, then choose the mix of channels and experiments that will move payback and LTV. If you need only design or only PR, we may not be the right fit.
Do you offer long-term contracts or a rolling retainer?
We work on a monthly rolling basis rather than locking you into long-term contracts. This keeps flexibility high, especially when market conditions, budgets or priorities change. Because we can scale specialist support up or down, you can invest where the bottleneck is right now. This is often simpler than hiring multiple London roles or managing fragmented agency suppliers.
Why choose Growthcurve as your marketing agency in London?

You get visibility through a real-time performance dashboard and decision-led reporting. Unlimited ad creative production is included and we charge no commission on ad spend.

Lifecycle marketing that increases LTV

If you only optimise acquisition, you end up paying more for the same customers. We build lifecycle systems that raise retention and expansion, using email, SMS where relevant, and CRM workflows that feel personal without being creepy. We set up segmentation based on behaviour and value, then design flows for onboarding, activation, replenishment, win-back and referral. In practice that can include RFM modelling for ecommerce, lead scoring for B2B, or product usage triggers for SaaS. We also help you capture first-party and zero-party data with preference centres and progressive profiling, so targeting stays resilient as privacy changes. When we ran a lifecycle audit for one team, we found revenue sitting in overlooked moments, like post-purchase education and renewal risk signals. The outcome is a healthier blended CAC and a marketing engine that keeps paying you back.

Measurement you can trust and use

Attribution arguments waste time and block good decisions. We set measurement up so it is good enough to guide spend, creative and roadmap choices, and we are honest about what is knowable. Tracking work can include GA4 hygiene, conversion event design, server-side tracking where appropriate, and consistent UTMs. Reporting lives in a real-time dashboard, with views that match how you run the business, such as channel performance, funnel conversion, cohort retention and creative learnings. We also use incrementality thinking where it matters, like geo holdouts or controlled tests for bigger budget shifts. For example, if brand search rises after a video push, we look at the whole picture rather than declaring victory based on last click. The outcome is faster iteration and fewer surprises in board meetings.

Operating rhythm, SLAs and ways of working

Good marketing is mostly good operations. We set a working rhythm that keeps delivery moving and prevents strategy decks from becoming a comfort blanket. You get a named lead, specialist channel owners, and access to top-tier US and UK talent, scaled up or down based on your needs. We agree response times, approval flows and who owns what across creative, landing pages, tracking and budget changes. Campaign planning happens in short cycles, with clear priorities and a shared backlog, so work does not disappear into a black box. We also help your internal stakeholders, like product, sales and finance, stay aligned with what marketing is doing and why. The outcome is a calm, consistent cadence, less context switching, and a team that behaves like your internal staff while staying on a monthly rolling basis.
