3What this role really is

A Lead Media Buyer designs and runs paid media campaigns across multiple channels, shaping strategy as well as executing it. The work involves building media plans that solve business problems and support measurable goals. It means acting as the technical expert on attribution and measurement, making sure budget is spent well and its impact proven. Part of the job is turning business objectives into media strategies, then making sure a team delivers on them.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

The Trade Desk, Google DV360 (DSPs) Expert

Designing complex programmatic strategies, troubleshooting pixel/tag issues, leveraging advanced features like custom bidding algorithms, and overseeing campaign execution.

Meta Ads, LinkedIn Ads, TikTok Ads (Social Ad Platforms) Expert

Setting cross-platform social strategy, allocating budgets based on business goals, and integrating social data with broader marketing mix models. You'll also be mentoring on advanced features like Conversion API.

Governing overall account structure, setting top-level bidding strategies, and ensuring search aligns with overall business and brand objectives. You'll be an expert in Performance Max and custom scripts.

Google Analytics 4 (GA4), Looker Advanced

Building custom reports and explorations in GA4 to answer strategic questions, creating complex, multi-source dashboards in Looker, and guiding your team on advanced analytics.

Anaplan, Tableau Server Intermediate

Utilising financial planning tools like Anaplan for budget forecasting and connecting media data to executive dashboards in Tableau for C-suite reporting. You'll be the bridge between media and finance.

Integral Ad Science (IAS), DoubleVerify (Ad Verification) Advanced

Customising verification settings based on campaign goals, analysing discrepancy reports, challenging vendors on performance, and setting brand safety policies for your team.

Managing complex project plans with multiple dependencies in Asana, leading discussions and problem-solving in Slack, using Confluence for strategic documentation (e.g., annual media plan), and collaborating with product/tech teams on marketing technology projects in Jira.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Campaign Budget Allocation (within approved total) Follows specific instructions from a senior team member; no independent allocation. Allocates budget across campaigns within a single channel, adhering to overall weekly/monthly targets. Escalates significant shifts. Allocates budget across multiple channels and campaigns, making optimisations to hit overall portfolio targets. Consults on major reallocations (£10K+).
New Platform/Vendor Evaluation & Selection Assists with data gathering and research for potential new tools. Researches and presents findings on potential new tools or vendors, but doesn't make final recommendations. Evaluates new platforms/vendors, conducts small-scale tests, and makes recommendations to leadership based on performance data.
Hiring & Performance Management for Direct Reports No involvement. May provide informal feedback to junior colleagues. Mentors junior team members; provides input on performance reviews for L1/L2.
Attribution Model Selection & Implementation Uses the standard, pre-defined attribution model for reporting. Can explain different attribution models and their implications, but doesn't define which one to use. Recommends specific attribution models for different campaign types or business questions, with supporting rationale.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Blended ROAS / CPA Improvement
The overall return on ad spend or cost per acquisition across all paid media channels you oversee.
Target · Improve blended ROAS by 10-15% year-on-year, or reduce blended CPA by 10-15% year-on-year, depending on business goals.

If our blended ROAS was £3.00 in Q1 2024, we'd expect to see it at £3.30-£3.45 by Q1 2025, assuming similar market conditions. This isn't just about one campaign; it's the whole portfolio.

Incrementality of Key Channels
Measuring the true incremental sales or leads driven by specific media channels, beyond what would have happened anyway.
Target · Successfully design and execute at least 4 incrementality tests per year, with clear, actionable findings that inform future budget allocation.

Running a geo-lift test for a new YouTube campaign to prove it's driving new customers, not just cannibalising existing demand. You'd present the findings and recommend a budget shift based on true lift.

Budget Pacing Accuracy & Optimisation
How accurately you and your team spend the allocated multi-million-pound budget, ensuring no significant over or under-spend, while optimising for performance.
Target · Maintain budget pacing within +/- 1% of target monthly spend, with clear explanations for any deviations, and demonstrate continuous optimisation efforts.

Managing a £500K monthly budget, you'd aim to spend between £495K and £505K, ensuring that any shifts (e.g., pulling budget from underperforming campaigns to high-performers) are justified and documented.

Successful New Channel/Feature Launches
The successful testing and scaling of new ad platforms, formats, or advanced features within existing platforms.
Target · Lead the successful launch and evaluation of at least 2 new significant media initiatives per year, with clear KPIs and a path to scale.

Successfully piloting a new ad format on TikTok that delivers a 20% lower CPA than existing formats, then developing a plan to scale it across relevant campaigns and sharing the learnings with the wider team.

Strategic Influence & Thought Leadership
Your ability to shape the overall media strategy, influence senior stakeholders, and act as a recognised expert in paid media.
  • You're proactively consulted on major marketing strategy decisions. Your recommendations are regularly adopted by leadership. You present compelling arguments for new budget allocations or strategic shifts. You're asked to lead internal workshops or share insights across departments. People come to you with their toughest media questions.
Team Mentorship & Development
How effectively you guide, develop, and empower your direct reports and junior team members.
  • Your direct reports show measurable improvement in their technical skills and strategic thinking. They feel supported and challenged. You regularly conduct constructive code reviews or campaign audits. You're seen as a trusted advisor, helping them unstick problems and grow their careers. We'd see positive feedback in 1-to-1s and performance reviews.
Complex Problem Solving & Attribution Mastery
Your skill in dissecting complex performance issues, untangling attribution challenges, and providing clear, data-backed solutions.
  • You can clearly articulate why different attribution models show different results and recommend the most appropriate one for a given business question. You troubleshoot significant performance drops or data discrepancies efficiently, presenting the root cause and a solution plan. You design custom reports that answer previously unanswerable questions for leadership.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Puzzles

You'll spend a good chunk of your week trying to figure out why ROAS dropped on a specific campaign, or how to accurately attribute conversions across 7 different touchpoints. It's like being a detective, but with data. You'll love untangling messy data and finding the 'aha!' moment.

Spending a full day digging into GA4, DSP logs, and CRM data to pinpoint why a high-performing audience segment suddenly stopped converting, then presenting a clear, data-backed hypothesis and solution.

Direct Business Impact

Your work directly influences how much revenue the company generates and how efficiently we acquire customers. You'll see the immediate results of your strategic decisions in dashboards and financial reports. There's a clear line from your actions to the company's success.

Designing a new full-funnel media strategy that, after 3 months, demonstrably reduces our blended CPA by 15% and directly contributes to hitting our quarterly revenue targets.

Mentoring & Building Capability

You'll be guiding and developing a small team of media buyers, helping them grow their skills and tackle more complex challenges. This means regular 1-to-1s, code reviews, strategy sessions, and helping them unstick problems. Seeing your team members succeed will be a big win for you.

Helping a junior media buyer troubleshoot a complex tracking issue, then empowering them to present the solution to the wider team, boosting their confidence and expertise.

What frustrates people
  • Attribution Hell: Fighting a multi-front war to prove your channel's value when GA4's data-driven model, the platform's own numbers, and a third-party tool all tell a different story. It's like trying to get three different witnesses to agree on what happened.
  • The Algorithm Giveth, The Algorithm Taketh Away: Waking up to find your best-performing campaign has been throttled by an unannounced algorithm update, and support's only answer is 'it's working as intended.' You'll spend hours trying to reverse-engineer something that's a black box.
  • Creative Blame Game: Being held 100% accountable for campaign performance when you're given low-quality creative, a slow landing page, and a weak offer, but have no authority to change them. It's like being asked to win a race with flat tyres.
  • The Cookiepocalypse Treadmill: Spending a significant portion of your time re-learning how to target and track users because of the latest privacy update from Apple or Google, making last year's strategy obsolete. Just when you think you've figured it out, something changes again.
  • "Just a Quick Question": The stakeholder 'quick question' that derails your entire afternoon because it requires pulling data from three platforms, building a custom report, and then explaining it in five different ways to answer. It's rarely 'quick'.
  • Budget Pacing Purgatory: The end-of-month stress of trying to spend the last £1,324.67 of a £500,000 budget without sacrificing performance, or worse, having to explain why you're £10K under budget. It's a delicate dance.
What this role does not give you
  • A static, predictable environment where strategies remain unchanged for years.
  • Complete control over all factors influencing campaign performance (e.g., creative, landing page conversion rates).
  • A role where you only execute; you'll be expected to think strategically and lead.
  • An easy ride with no urgent requests or unexpected challenges.

8Who you work with

This role directly impacts our customer acquisition efficiency and overall marketing ROI. You're accountable for how millions of pounds are spent annually, and your strategic decisions will dictate our market reach, brand visibility, and ultimately, our growth trajectory. Getting this right means we scale efficiently; getting it wrong means we burn through cash without the desired impact. You'll also be building the capability of our junior media buyers, which is crucial for our long-term team strength.

Inside the business
  • Media Buying Manager (your direct boss)
  • VP of Marketing (for strategic alignment)
  • Head of Product (for landing page optimisation and product-led growth initiatives)
  • Sales Leadership (to ensure lead quality and volume)
  • Data & Analytics Team (for advanced attribution and reporting needs)
  • Creative Team (to brief and get the best performing assets)
Outside the business
  • Major Ad Platform Representatives (Google, Meta, TikTok, LinkedIn)
  • Demand-Side Platform (DSP) Account Managers (The Trade Desk, DV360)
  • Ad Verification & Measurement Vendors (IAS, DoubleVerify)
  • Strategic Media Partners (publishers, affiliate networks)
  • External Agencies (if we use them for specific channels or projects)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • Proven track record of managing multi-million-pound paid media budgets across multiple channels (e.g., programmatic, social, search).
  • Demonstrable experience in designing and executing complex media strategies that have delivered measurable business impact (e.g., significant ROAS improvement, CPA reduction).
  • Strong analytical skills, including advanced proficiency in Excel/Google Sheets, and experience with data visualisation tools (e.g., Looker, Tableau).
  • Experience leading or mentoring a small team of media buyers, providing guidance and fostering their development.
  • Ability to present complex data and strategic recommendations clearly and confidently to senior stakeholders.
  • A deep, practical understanding of attribution models and incrementality testing methodologies.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Marketing Mix Modelling (MMM) & Econometrics

With the decline of cookie-based tracking, top-down approaches like MMM are experiencing a resurgence. You'll need to move beyond basic understanding to actively contributing to and interpreting complex econometric models that inform our highest-level budget decisions.

Bayesian statistics in MMM · Feature engineering for MMM · Interpreting model outputs for budget allocation · Open-source MMM frameworks (e.g., Robyn, Orbit)

  • This week: Read articles on the resurgence of MMM and its role in a cookieless world.
  • This month: Take an online course on econometric modelling or advanced statistics for marketing.
  • Month 2: Work with our Data Science team to understand their current MMM approach and identify areas for your contribution.
  • Month 3: Propose a pilot project to test an open-source MMM framework on a specific business problem.

Quick win: Start following influential data scientists and marketing leaders who are actively discussing MMM on platforms like LinkedIn and Twitter. Engage with their content and ask questions.

AI-Driven Creative Optimisation & Generation

AI is rapidly changing how we create and test ad creative. You'll need to move from manually briefing creative to using AI tools to generate variations, predict performance, and optimise creative elements at scale. This will be a huge differentiator.

Generative AI for ad copy and image creation · Predictive creative scoring · Dynamic Creative Optimisation (DCO) with AI · Ethical considerations in AI creative

  • This week: Experiment with a generative AI tool (e.g., Midjourney, ChatGPT) to create ad copy or image concepts.
  • This month: Research AI-powered DCO platforms and their capabilities.
  • Month 2: Collaborate with the Creative team to propose an AI-assisted creative testing framework for a new campaign.
  • Month 3: Present your findings and a roadmap for integrating AI creative tools into our workflow.

Quick win: Use AI tools to quickly generate multiple headlines or calls-to-action for your next campaign. It's a low-risk way to see the potential.

11Staying current once you are in

What people here do to keep up
  • Regularly attending industry conferences and webinars (e.g., AdWeek, Programmatic IO, DMEXCO) to stay abreast of the latest trends and network with peers.
  • Subscribing to leading industry publications and newsletters (e.g., AdExchanger, Marketing Week, Search Engine Land) to keep up with news and analysis.
  • Actively participating in online communities or forums dedicated to paid media or ad tech, sharing knowledge and learning from others.
  • Taking advanced courses in data science, statistics, or econometrics to deepen your analytical capabilities.
  • Mentoring junior professionals outside of your direct team, which helps solidify your own knowledge and leadership skills.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, as a Lead Media Buyer, your time is precious. You should be focused on strategic thinking, team development, and solving our toughest marketing puzzles, not getting bogged down in repetitive tasks. That's where AI comes in.

We're building an AI-first marketing team, and we want you to be at the forefront of this transformation. Imagine offloading the grunt work to intelligent tools, freeing you up to truly architect our media future. Our AI Productivity Hub is packed with tools and guides to help you do just that.

Repetitive Campaign Trafficking Automation

Use AI scripts to automatically generate hundreds of ad variations by combining approved headlines, descriptions, images, and videos. This eliminates hours of manual 'copy and paste' work in platform UIs, letting you focus on creative strategy and testing. You'll spend less time in spreadsheets and more time thinking about what truly resonates.

Predictive Audience & Bid Analysis

Leverage AI tools to analyse historical data and predict which audience segments will have the highest lifetime value (LTV). Get real-time recommendations to shift budget from underperforming to high-potential audiences before a human could even spot the trend. This means smarter, faster budget allocation and better ROAS.

Automated Performance Summaries

Connect AI to your analytics platforms to generate first-draft weekly and monthly performance reports. The AI can summarise key trends, flag anomalies, and write the initial narrative, which you then refine with your strategic insights and present to leadership. Less time reporting, more time strategising.

Competitor & Creative Intelligence

Use AI-powered ad intelligence tools to monitor competitor media strategies, identify their top-performing ad creative, and analyse the messaging that resonates most in your market. This provides invaluable inspiration for your next campaign and helps you stay ahead of the curve without endless manual research.
