What a consultant should deliver

A growth marketing consultant should do more than share ideas. You need a clear diagnosis of the growth constraint, a prioritised roadmap, and a way to execute and learn quickly. The work typically spans acquisition, activation, retention and revenue, with measurement that ties activity to outcomes like conversion, CAC and payback. The best engagements run in sprints, with a backlog of tests, clear owners, and weekly reporting that drives decisions on what to scale, stop, or fix next.

Diagnose the bottleneck

Audit acquisition, conversion and retention to find where value is leaking, then focus effort on the constraint that limits revenue.

Build a sprint roadmap

Create a prioritised backlog of experiments with clear hypotheses and success metrics, so the team learns fast and avoids random work.

Improve unit economics

Optimise towards CAC payback, conversion rate and retention, so scaling spend becomes safer and forecasting becomes more reliable.

Get a plan

Get clarity, then speed

Growth work fails when teams jump straight to tactics. They add channels, spend more, or copy competitors, but results stay unstable because the underlying constraint is not understood. We start with clarity: what is the bottleneck, what data is trustworthy, and which levers will change unit economics. Then we move fast with a sprint cadence, shipping and testing improvements weekly. You get momentum with accountability, not a slide deck that sits untouched.
  • Constraint-first growth diagnosis
  • Weekly shipped improvements
  • Less guesswork, more signal

Acquisition and conversion

When growth stalls, it is often because acquisition and conversion are managed separately. We align channel strategy, creative, landing pages and analytics so performance improves end-to-end. Paid search and paid social are structured for learning and scaling, with weekly creative iteration. CRO focuses on the steps that influence revenue most, improving message match, proof, and user flow. You get a single view of what is driving qualified conversions, and a sprint cadence that turns insight into shipped improvements.

Paid channel optimisation

Build campaigns around meaningful conversion events, then refine targeting, bidding and creatives so spend drives quality, not just volume.

Landing page and CRO tests

Prioritise A/B tests on key pages using analytics and user behaviour signals, improving clarity and reducing friction to lift conversion.

Measurement you can act on

Standardise events and dashboards so weekly decisions are grounded in outcomes like qualified leads, revenue, or pipeline contribution.

Fix acquisition

Retention and lifecycle

Most teams underinvest in retention, then try to compensate by buying more traffic. We design lifecycle programmes that increase activation, reduce churn, and lift LTV, making paid growth sustainable. That includes behaviour-triggered onboarding, segmented nurture, and win-back campaigns, plus ongoing experimentation on offers and messaging. We track retention and revenue by cohort so you can see whether growth is real, and which changes improved long-term performance rather than short-term metrics.

Activation and onboarding flows

Reduce time to value with triggered onboarding and in-product prompts, so more new users reach the activation moment quickly.

Segmented nurture and scoring

Use behaviour and intent signals to tailor email and messaging, improving engagement and moving prospects to the next step.

Win-back and reactivation

Run targeted reactivation campaigns for lapsing users and leads, increasing revenue without relying only on new acquisition.

Improve retention

Better than fractional

Fractional consultants can be helpful, but many are limited to advice and cannot sustain execution velocity. Freelance teams can ship, but often lack leadership, consistency, and clean measurement. We combine senior growth leadership with a delivery team, so strategy and execution stay connected. Specialists can scale up or down as needed, without long-term contracts. That reduces risk, keeps cadence high, and avoids the inconsistency that comes from stitching together multiple freelancers.
  • Strategy plus execution team
  • Avoid inconsistent freelancers
  • Scale support up or down

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 does a growth marketing consultant actually do?
A growth marketing consultant diagnoses where growth is constrained, then builds a prioritised plan to improve the full funnel. That typically covers acquisition, activation, retention and revenue, with clear measurement. In practice, that includes auditing tracking and conversion events, defining hypotheses, and running experiments across channels, landing pages and lifecycle messaging. The best consultants tie work to outcomes such as CAC, conversion rate, retention and payback, not just activity metrics.
Should I hire a consultant or a growth agency team?
Hire a consultant if you mainly need senior direction and you already have a capable team to execute. Hire a growth team if execution is your bottleneck or you need multiple specialists across paid, creative, CRO and lifecycle. Many companies underestimate the delivery load behind good strategy. If you want faster iteration, a team model often wins because it keeps strategy and execution connected and removes the delays of coordinating multiple suppliers.
What deliverables should a growth marketing consultant provide?
You should expect a clear diagnostic, a prioritised roadmap, and a regular execution and reporting rhythm. Deliverables often include a measurement plan, growth model assumptions, experiment backlog, and weekly or fortnightly sprint updates. The key is that deliverables drive decisions. If you only receive slide decks without shipped work, tracking improvements, or tested learnings, you will not get compounding results. A good consultant makes progress visible and measurable.
Which metrics matter most when working with a consultant?
Focus on metrics that connect marketing to the business. Common examples include CAC, CAC payback period, conversion rate through key funnel steps, retention, and LTV by cohort. Channel metrics like CTR or platform ROAS can be helpful for diagnosing performance, but they are not the score. If the consultant cannot show how work changes conversion quality or payback, you risk scaling activity without improving outcomes.
How do you decide what to test first?
We start with the biggest constraint, then build a backlog of opportunities across acquisition, conversion and retention. Tests are prioritised by expected impact and effort, with clear hypotheses and success criteria. This approach prevents random experimentation and keeps effort focused on high-leverage steps like landing pages, onboarding, offers, and channel structure. Each sprint ends with a decision: what to scale, what to pause, and what to test next.
How long does it take to see results?
Some improvements show within weeks, especially tracking fixes, creative iteration, and landing page clarity changes. These can reduce wasted spend quickly and improve the quality of learning. Compounding results take longer, particularly retention and lifecycle work where cohorts need time to mature. The goal is to build a repeatable sprint cadence so progress continues month after month, rather than relying on one-off wins or short-lived spikes.
Will you work inside our tools and with our team?
Yes. A growth marketing consultant should integrate with your team and operate inside your existing stack where possible, so learning and processes stay with you. That usually includes your ad accounts, analytics, CRM, and experimentation tools. We agree ownership upfront, then run sprints with clear deliverables and feedback loops. This keeps execution moving while improving internal capability and ensuring decisions are aligned with product, sales and finance.
How do you report performance when attribution is messy?
We standardise first-party events and focus reporting on outcomes across the funnel. That includes conversion rate by step, cohort retention, and revenue quality by source, not just platform dashboards. When attribution is uncertain, we use practical validation methods like controlled budget changes and consistent campaign structures to identify what is driving improvements. The goal is decision confidence, so you can scale winners and stop waste without attribution debates.

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.
