A practical guide to hiring a media buyer: the types of media buying roles, which skills to require, a 30-minute account walkthrough, scored interview questions, red flags and a 90-day plan.
- “Media buyer” ranges from a programmatic or traditional media negotiator to a performance marketer running paid social and search, so define channels, monthly spend and goals before posting.
- Ask for specific numbers: budgets managed, target metrics (CPA, ROAS, CPM) and what they changed when results fell short.
- A 30-minute account walkthrough plus a short case exercise shows real skill better than certifications alone.
- Google Ads certifications expire after one year, so check that any certification listed is current.
- Decide early whether you need an employee, a contractor or an agency, because the hiring process and legal obligations differ.

To hire a media buyer, first decide which channels and budget size the person will manage, then screen for hands-on platform experience, test their thinking with a 30-minute walkthrough of a real (anonymized) ad account, and ask structured interview questions about budgets, measurement and mistakes. The best predictor is how a candidate explains past spend decisions and results, not a list of platforms on a résumé.
What a media buyer does
A media buyer purchases advertising space or audience impressions to reach a target audience at the best possible cost, then manages and adjusts that spend based on results. In most companies today, the job falls into one of these patterns:
| Type of media buyer | Typical channels | Core skills |
|---|---|---|
| Performance / paid social and search buyer | Meta, Google Ads, TikTok, LinkedIn, Microsoft Ads, Amazon Ads | Campaign setup, audience and bidding strategy, creative testing, conversion tracking, daily optimization |
| Programmatic buyer | Demand-side platforms (DSPs), connected TV, display, digital audio | Deal types, inventory quality, frequency and brand-safety controls, data partnerships |
| Traditional / agency media buyer | Broadcast and cable TV, radio, print, out-of-home | Negotiating rates and placements with sellers, ratings and reach data, insertion orders, make-goods |
| Media planner-buyer (hybrid) | Mix of the above | Budget allocation across channels, media plans, vendor management, reporting to leadership |
Media buying overlaps with but is different from social media management, which focuses on organic content and community. If that’s closer to your need, see our social media manager hiring playbook.
Employee, contractor or agency: choose the hiring model
| Option | Best when | Watch out for |
|---|---|---|
| Full-time employee | Paid media is a core, ongoing growth channel and you want the knowledge in-house | One person rarely masters every channel; budget for tools and training |
| Contract or freelance buyer | You need help for a launch, a test or a seasonal push, or you’re not sure yet how much work there is | Worker classification rules; account ownership and access when the contract ends |
| Agency | You need several channels, creative production and buying power at once | Less control and visibility; fees tied to spend can reward spending more |
| Contract-to-hire | You want to see real results in your accounts before making a permanent offer | Agree conversion terms in writing up front |
Whatever you choose, keep ad accounts, pixels and analytics in your company’s name and grant the buyer access, so you never lose your data when people change. If you go the contractor route, our guide to the contractor onboarding process covers classification and setup.
Media buyer skills to require
Separate must-haves from nice-to-haves, and tie each to the work. A typical must-have list for a performance-focused role:
- Hands-on management of campaigns in the platforms you use, at a budget level close to yours.
- Clear grasp of the metrics that matter to you: cost per acquisition (CPA), return on ad spend (ROAS), cost per thousand impressions (CPM), click-through and conversion rates.
- Structured testing: changing one thing at a time, letting tests run long enough, and knowing when results are noise.
- Tracking and measurement basics: conversion events, UTM parameters, attribution windows, and how platform-reported results can differ from your analytics or CRM.
- Budget pacing and spreadsheet skills to forecast, reallocate and report spend.
- Clear written reporting for non-specialists: what happened, why, and what to do next.
Nice-to-haves include creative briefing skills, SQL or a BI tool, experience with a specific industry’s ad policies, and negotiation experience for direct deals. Our guide to skills-based hiring explains how to write requirements around skills rather than years of experience.
Certifications are a reasonable signal of platform knowledge but not of judgment. Google states that a Google Ads product-area certification is valid for one year and must be renewed by retaking the assessment on Skillshop, so check that any listed certification is current. Certifications are earned per product area (Google’s Partners program requirements name Search, Display, Video, Shopping and Apps as examples), so look for the areas that match your channels.
The 30-minute account walkthrough
This is the most revealing step. Ask the candidate to walk you through a campaign they managed. Make it clear they must not share a former employer’s or client’s confidential data: they can present from memory, use redacted screenshots, or work from a sample account you provide.
| Minutes | What the candidate covers | What you’re listening for |
|---|---|---|
| 0-5 | Goal, audience, channels and monthly budget | Can they state the business goal and the metric that defined success? |
| 5-15 | Account structure, targeting, bidding and creative approach | Clear reasons for each choice, not “that’s how it’s done” |
| 15-25 | A test or change they made, and what the numbers showed | Specific before-and-after figures, awareness of sample size and tracking limits |
| 25-30 | What went wrong and what they would do differently | Honest ownership of a mistake, a concrete lesson |
Score each block from 1 to 5 against the “listening for” column. Follow up with a short case exercise for finalists: give them a one-page brief with a budget, a goal and two weeks of sample (fictional) campaign data, and ask for a 1-page plan. Keep it under two hours of work, give every finalist the same brief, and don’t use their output in your real campaigns.
Media buyer interview questions
Ask every candidate the same questions and score answers on a shared interview scorecard.
| Area | Question | A strong answer includes |
|---|---|---|
| Budget | What is the largest monthly budget you’ve managed, and how did you decide how to split it across channels? | Real figures, a method (past performance, tests, margin targets), willingness to move money |
| Diagnosis | CPA rose 40% last week with no changes on your side. Walk me through how you’d investigate. | Checks tracking first, then auction costs, creative fatigue, audience overlap, landing page, seasonality |
| Testing | Describe a test you ran that didn’t work. How did you know it was finished? | One variable, enough data, a decision rule, what they learned |
| Measurement | How do you handle differences between what the ad platform reports and what our analytics or CRM shows? | Understands attribution windows and models, uses a source of truth, explains gaps to stakeholders |
| Creative | How do you work with designers or creators to improve ad performance? | Clear briefs, testing hypotheses, sharing results, respect for brand guidelines |
| Reporting | How would you explain a bad month to our CEO in three sentences? | What happened, why, what’s changing, with numbers and no jargon |
| Negotiation (traditional/programmatic) | Tell me about a placement or rate you negotiated. What did you trade? | Specific terms, value added (make-goods, placement, flighting), relationship kept |
Keep every question job-related. Our guide to illegal interview questions lists topics to avoid.
Red flags when hiring a media buyer
- No numbers. Can’t name budgets, targets or results for any campaign they ran.
- Credit for everything. Every win was theirs; every loss was the client’s or the platform’s fault.
- Platform-only thinking. Treats platform-reported ROAS as the final word and never checks it against sales or leads.
- Willing to share confidential data. Offers a former client’s live account access or unredacted reports. They’ll do the same with yours.
- Hacks over method. Talks mostly about tricks and settings rather than goals, testing and measurement.

Frequently asked questions
What does a media buyer do?
A media buyer purchases ad space or audience impressions across channels such as paid social, search, programmatic display, TV, radio or out-of-home, aiming to reach the right audience at the best cost. They set up and manage campaigns or negotiate placements, track results against goals like cost per acquisition or return on ad spend, and move budget to what works.
What skills should a media buyer have?
Core skills are hands-on experience in the relevant ad platforms, comfort with metrics such as CPA, ROAS and CPM, structured A/B testing, conversion tracking and attribution basics, budget pacing in spreadsheets, and clear reporting. Traditional and programmatic buyers also need negotiation skills and knowledge of inventory quality and deal types.
Should I hire a freelance media buyer or a full-time employee?
Hire full-time when paid media is an ongoing core channel and you want the expertise in-house. Use a freelance or contract buyer for launches, tests or uncertain workloads, and consider contract-to-hire if you want to see results before committing. In every case, keep ad accounts and tracking owned by your company.
How do you test a media buyer before hiring?
Use a 30-minute walkthrough of a campaign they managed (with confidential data removed), followed by a short case exercise for finalists: a one-page brief with a budget, a goal and sample data, answered with a one-page plan. Score both with the same rubric for every candidate and keep the exercise under two hours.
What is the difference between a media buyer and a media planner?
A media planner decides strategy: which audiences, channels and timing to use and how to divide the budget. A media buyer executes: purchasing placements or running campaigns, negotiating or bidding for cost, and optimizing spend. In smaller teams and most digital roles, one person does both.
