5 Star Agency

What growth means

Growth agency marketing is not a channel. It is an operating system for improving the whole customer journey, using fast experimentation and clear measurement. We work across AARRR: acquisition, activation, retention, referral, and revenue. That means running paid and organic acquisition, fixing funnel leakage with CRO, building lifecycle automation, and tying it all to unit economics like CAC payback and LTV. You get weekly shipping, clear learnings, and a plan that compounds.

AARRR metrics and focus

Align on one North Star metric and the AARRR inputs that drive it, so every sprint improves a measurable growth lever.

ICE prioritisation framework

Score experiments by impact, confidence, and effort to focus limited time and budget on the highest-leverage tests first.

Cohorts over vanity metrics

Track activation and retention cohorts so you scale what improves customer quality, not what inflates clicks, leads, or short-term ROAS.

Get a sprint plan

Old way vs new

Traditional agency marketing often means slow cycles, siloed channel teams, and reporting that explains results after the fact. Growth agency marketing should feel like a product team: short cycles, clear hypotheses, and measurable learning. We run weekly sprints with a single backlog across paid, creative, CRO, lifecycle, and analytics. This keeps focus on the next highest-impact test and builds a compounding system, not a set of disconnected activities.
  • Weekly sprint delivery cadence
  • One backlog across funnel
  • Hypothesis-led experimentation

Acquire efficiently

Acquisition should be scalable, measurable, and creative-led. We build channel strategies across Google, Meta, TikTok, LinkedIn, and programmatic where it fits, then execute with a testing cadence designed to produce interpretable learnings. The work includes offer and messaging iteration, creative production at volume, audience strategy, and clean separation of prospecting and retargeting. We also keep incentives aligned with no commission on ad spend, so recommendations are driven by outcomes.

Creative testing pipeline

Ship weekly variations across hooks, proof, and offers so you beat fatigue and find winners that can scale predictably.

Search and intent capture

Capture demand through high-intent search while managing query quality and landing page match, so growth stays profitable as spend rises.

Programmatic and audience extension

Use controlled reach and frequency to extend audiences beyond core platforms, then validate performance with incrementality-aware measurement.

Scale acquisition

Convert and retain

Most growth stalls because conversion and retention do not keep up with acquisition. We improve conversion through CRO and funnel diagnostics, then build retention through lifecycle marketing and product-led growth tactics. That includes landing page tests, onboarding improvements, behaviour-triggered email journeys, and churn analysis through cohorts. Measurement stays decision-grade with consistent event definitions and first-party tracking foundations, so you can scale confidently as attribution signals change.

CRO and leakage fixes

Use heatmaps, recordings, and A/B tests to remove friction, improve message match, and increase conversion on the highest-impact journeys.

Lifecycle automation journeys

Build onboarding, nurture, win-back, and upsell flows in tools like HubSpot or Klaviyo, triggered by behaviour and customer value.

Retention cohorts and LTV

Track retention by cohort and segment, then prioritise changes that improve LTV and payback, not just short-term conversion rate.

Improve retention

Clarity and trust

If your team cannot trust numbers, growth slows into internal debate. We focus on decision-grade measurement: consistent event definitions, first-party tracking foundations, and a real-time performance dashboard that shows what matters. Reporting is built to drive action. Each week you see what shipped, what changed, what we learned, and what we will do next. That transparency helps leaders move budget and resources quickly toward what is working.

  • Real-time dashboard visibility
  • Clear weekly decision narrative

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 is growth agency marketing in practical terms?
Growth agency marketing is a full-funnel approach that improves acquisition, activation, retention, referral, and revenue using fast experimentation. Instead of treating channels as separate workstreams, growth connects paid, SEO, CRO, and lifecycle into one system. Practically, you get a sprint cadence, a prioritised backlog, and clear hypotheses. Success is judged by unit economics and cohort quality, not by isolated channel metrics.
How is a growth agency different from a traditional agency?
Traditional agencies often optimise within a channel and report monthly. A growth agency should optimise the customer journey end to end, with short cycles and measurable learning. You should see weekly shipping, clear owners across creative and analytics, and decisions tied to payback and retention. If the agency cannot explain what changed this week and why, it will struggle to deliver compounding results.
What metrics should we track for growth work?
Start with a North Star metric that reflects value delivered, then track the few inputs that drive it. Most teams use a version of AARRR: acquisition, activation, retention, referral, and revenue. For commercial control, track CAC, CAC payback, and LTV by cohort and segment. This avoids scaling spend on customers who look good in short-term dashboards but churn quickly.
How do you prioritise experiments without wasting budget?
We prioritise with a scoring framework such as ICE: impact, confidence, and effort. This keeps attention on the highest-leverage tests and reduces time spent on low-impact ideas. We also set measurement guardrails, such as required sample sizes and clear success metrics, so decisions are not made on noise. The goal is to learn quickly, but not carelessly.
Which channels usually work best for growth marketing?
There is no universal best channel. The right mix depends on your audience, sales cycle, and unit economics. Paid can provide fast feedback loops, SEO compounds over time, and lifecycle increases LTV to make acquisition scalable. We usually start with the channels that can produce clean learning quickly, then expand once conversion and retention are stable enough to support scale.
How do you improve conversion rates in growth programmes?
We focus on the pages and steps that drive the most revenue impact, then run hypothesis-led CRO tests. Inputs include heatmaps, session recordings, funnel drop-offs, and message match between ads and landing pages. This approach avoids long redesign cycles. Small conversion lifts often compound across paid and SEO because the same improvements increase performance everywhere traffic lands.
How do you handle attribution and tracking changes?
We aim for decision-grade measurement based on consistent event definitions and first-party tracking foundations. Platform dashboards are useful, but not reliable enough to be the only decision input. Where attribution is uncertain, we rely on cohort trends and structured tests to validate lift. This helps you scale what is truly incremental and avoid over-investing in channels that only capture existing demand.
What should we look for when hiring a growth agency?
Look for an operating model, not just promises. Ask what ships weekly, how experiments are prioritised, and who owns creative, landing pages, and analytics. Confirm how reporting supports decisions rather than describing activity. Also check incentives. Commission models can push spend without accountability. A good agency will talk about payback, cohorts, and trade-offs, not just ROAS screenshots.

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.
