Growth Marketing Agency for Brands That Want Compounding Results

A growth marketing agency is a team that runs every marketing channel against one commercial target, rather than selling channels one by one. It plans across acquisition, conversion and retention, tests constantly and moves budget to whatever proves it earns revenue.

Shamrock runs eight disciplines from one plan: strategy, SEO, websites, PPC, social media, copywriting, design and PR. Each has its own specialists, but all of them report into the same dashboard and the same revenue target, so no channel is judged on numbers that never reach the bank.

Growth marketing covers the whole customer lifecycle and judges every channel by revenue, while digital marketing often means running online channels one at a time. A digital campaign can succeed on clicks alone. A growth programme only succeeds when revenue per customer rises.

The practical difference is where budget goes. A digital marketing agency usually grows the channel it was hired for. A growth marketing agency moves money between channels and stages, including retention, whenever the data shows a better return somewhere else.

A full-service marketing agency plans and runs strategy, search, paid media, social, web, copy, design and PR under one roof, so you brief one team instead of managing several suppliers.

The benefit is not just convenience. When the same team runs SEO and PPC, search data from paid campaigns shapes content within the month. When PR and SEO sit together, every campaign is planned for coverage and links at once. Our growth marketing services page shows how the eight services connect.

The cost depends on scope: how many channels you need, how much we execute versus your team and how competitive your market is. We do not publish a rate card. After the audit, you get a fixed fee in writing before you sign, with ad spend kept separate.

Engagements usually start from $3,000 a month in fees. Ad spend is paid directly to Google, Meta and the other platforms from your own accounts, never routed through us.

A Growth Retainer runs on a 6-month minimum term, then rolls month to month with 30 days' notice. Projects run for a fixed term set by their scope, and a Growth Sprint lasts 90 days. You never sign an open-ended commitment you cannot review.

Six months is the shortest period in which most channels can be built, tested and judged fairly. If you want proof before committing that long, the Growth Sprint audits your funnel, fixes the weakest stage and reviews results at day 90.

Most clients see early movement inside 90 days and compounding results from month six onwards. Paid media can produce leads within days of launch. SEO and PR build more slowly but keep paying back, and your plan states when each target can fairly be judged.

The first 90 days move from audit to plan to the first live tests. Months three to six run monthly tests on offers, pages, audiences and subject lines. From month six, budget and effort move towards whatever the data proves, and gains compound quarter on quarter.

Choose a marketing agency that agrees a commercial target in writing, shows you who will do the work and reports revenue before clicks. An agency that cannot say how it will be judged is hard to hold accountable.

Ask to see results from a business with a similar sales model, ask who owns the ad accounts and data, and ask what happens if a channel stops paying. Our case studies show the work behind each result, and you meet your named lead before you sign.

You get a live dashboard, a written monthly report and a call to walk through both. The report opens with performance against target, names anything that missed and sets out next month's actions. You keep full access to every platform throughout.

Every channel reports into the same dashboard, so revenue is traced to the channel that earned it and no two suppliers claim credit for the same sale.

We offer marketing strategy, SEO, websites, PPC, social media, copywriting, design and PR. Most clients start with the two or three channels the audit shows will pay back first, then add more once the first targets land.

Each service has its own page with scope, process and FAQs: marketing services, SEO services, website services, PPC services, social media services, copywriting services, design services and PR services.

We work mostly with SaaS, e-commerce, professional services, healthcare, education, finance, home services and hospitality brands. The method stays the same across sectors. The channel mix changes with how each market buys.

A SaaS company usually leans on SEO, PPC, content and LinkedIn, reported as demo requests and pipeline. A home services business leans on local SEO, PPC, the website and reviews, reported as booked jobs.

An agency usually gives you more skills for less management time, while an in-house team gives you more day-to-day control. Many clients combine both: an in-house marketer owns the brand voice, and we carry strategy and the specialist channels behind them.

Hiring in-house means recruiting each role, buying tools and training, which takes months per senior hire. An agency starts in week one with specialists already in place, and scope can flex up or down each quarter.

Onboarding takes about 3 weeks and ends with a signed-off growth plan. We collect platform access, run the discovery session and complete the audit. You meet your named lead in week one and see the plan before any budget moves.

The audit covers analytics, ad accounts, search visibility, the website and customer data, with competitors given the same scrutiny. It shows where revenue leaks today, stage by stage, and which fixes pay back first.

We track revenue, qualified leads, cost per acquisition, return on ad spend and customer lifetime value. Traffic, rankings and engagement appear as supporting signals, never as the headline. The exact KPIs are agreed in writing during planning.

We work in your existing stack first: GA4, Search Console, your CRM and your ad accounts. On top, we add rank tracking, call tracking and a reporting layer that reads every source into one dashboard. Every tool we add is named in the proposal.

You own every account, asset and dataset, from ad accounts and analytics to the website code. We work inside accounts registered to your business. When an engagement ends, nothing needs transferring, because nothing was ever in our name.

Engagements usually start from $3,000 per month in fees, with ad spend on top. Below that level, there is rarely enough budget to test properly across more than one channel. The audit shows whether a smaller start makes sense for you.

For paid media, we recommend at least $2,000 a month in ad spend per platform, so campaigns gather enough data to optimise.

Every client gets a named growth lead backed by a specialist for each channel in the plan. The lead owns your targets and your monthly review. Specialists in SEO, paid media, creative, web and PR do the work and join calls when their channel is on the agenda.

You can meet the people behind the work on our team page.

You get a monthly review call, a shared channel for day-to-day questions and replies within one working day. Launches and live campaigns get weekly check-ins. You never wait for the monthly report to hear about a problem.

Switching runs as a planned handover of about 4 weeks, with live activity kept running. We audit what your current agency runs, secure access to every account and keep campaigns live during the move. Nothing gets paused until its replacement is ready.

The most common problem in a switch is accounts registered in the old agency's name. We check ownership in week one, so any transfer can be requested before notice periods end.

The first 90 days move from audit to plan to the first live tests. Month one covers discovery, the audit and the written plan. Month two puts campaigns and fixes live. Month three delivers the first scorecard against target, reviewed together on a call.

After onboarding, most clients spend about 2 hours a month with us, plus sign-off on major creative and budget changes. Book a growth call to see what your first 90 days would cover.
