To hire a paid social media buyer, test their diagnosis before their vocabulary. Give each candidate the same redacted account export, ask for a one-page audit, then interview everyone with the same questions and agree who owns the ad accounts before anyone gets access.
If you want a Media Buyer already tested on agency work, start a Direct Hire brief or explore Managed Teams. Compare both on the pricing page.

- Acas describes a scoring system as one fair way to compare applicants. Updated 30 June 2026; checked 10 November 2026.
- On unpaid work trials, Acas says the time should be reasonable, for example 2 hours or a shift, and not usually longer than one day. It adds that the minimum wage must be paid if the trial is not genuinely for recruitment. Updated 30 June 2026; checked 10 November 2026.

What does a paid social media buyer own?
A paid social media buyer plans, launches and manages paid campaigns on platforms such as Meta and TikTok. Define the scope before you recruit, because the title covers very different jobs. Decide the platforms, the objective, and whether the person executes a plan or also sets the strategy and writes the report.
Separate the neighbouring roles so you hire for the right gap:
- A Media Buyer runs daily account operations and the test cycle.
- A Paid Social Analyst turns platform data into the weekly report and decisions.
- A Creative Strategist decides which angles to test and briefs the creative.
If performance is stuck because nobody knows what to test next, you may need creative strategy more than buying. If the problem is structure, tracking or wasted spend, hire the buyer first.
How do you run the account audit test?
Give each candidate read-only access to a redacted or fictional ad account export and ask for a one-page written audit within a few days. A written audit shows how someone thinks, which an interview rewards less reliably.
Ask the same four questions of everyone:
- What would you change first, and why?
- What would you deliberately leave alone for now?
- What would you test in the first week, and how would you know whether it worked?
- What can you not tell from the account alone, and what would you ask me?
Read each audit for diagnosis before action, respect for what is already working and honesty about uncertainty. A candidate who proposes a full rebuild without asking about your margins or goals has told you how they work.
Do not use live client accounts or real client data for the test, and do not give write access. Acas notes that a trial can become paid work when the tasks have value to the employer beyond testing skills, so fictional data protects both sides.
How do you score the audit?
Set the criteria before you read any audit, and score every candidate on the same scale. Use a range wide enough to separate candidates, record the evidence for each score and have a second person score independently.
Diagnosis
- Evidence: Names specific structure, tracking or testing problems found in the export.
Restraint
- Evidence: Says what they would leave running and why.
Test plan
- Evidence: States a first-week test with a success measure and a point to stop.
Honesty about gaps
- Evidence: Says what the export cannot show and asks for it.
Reporting judgement
- Evidence: Ties results to business measures such as new-customer revenue or margin, not only platform screenshots.
The example is a starting point. Agree what each score means before you review.
Which interview questions should you ask?
Ask the same core questions of each person, then follow up on their answers.
- "Walk me through how you would approach this account in the first 30 days."
- "How do you decide that a test has lost?"
- "Tell me about an account that did not go well. What did you miss?"
- "What does a creative brief from you look like?"
- "What would I see from you every Monday?"
- "Which platform are you strongest on, and where are you weakest?"
Listen for specific steps and honest answers. Vague answers full of buzzwords, or a promise that every account will improve, are a warning sign.
What should weekly reporting look like?
Ask for a short written report in the same format each week: spend and results by channel, what changed and why, what happens next, and what the buyer is unsure about. A dashboard link is not a judgement.
Also agree what happens when data is missing or a tracking gap makes a report incomplete. The buyer should mark unavailable figures as unavailable, never as zero, and escalate rather than guess. See the Paid Social Analyst role for the reporting side of the work.
Who should own the ad accounts?
Your agency or the client should own the ad accounts, pixels and creative files. Give the buyer an individual login with the permissions their tasks need, and keep billing and permission management with the owner. Confirm each platform's own rules on sharing access before you grant it.

Should you hire a freelancer, an agency or an offshore operator?
Choose by how much control, continuity and management time you need, not by a headline price.
- Freelancer. Flexible for a defined scope, but you manage the work and continuity depends on one person.
- Agency. Brings a team and process, but priorities and reporting follow the agency's own cadence.
- In-house hire. Gives you one accountable person and your own data, but takes recruiting time and needs a manager.
- Offshore operator. A dedicated person inside your tools and review process. Staff Stack lists the Media Buyer role at USD 2,800 to 4,200 per month, which is the role's current monthly pricing band; your quote depends on the operator and scope. Estimate a team budget with the operator cost calculator.

How do Direct Hire and Managed Teams compare?
Compare both options against the same role, schedule and support needs. With Direct Hire, discuss the placement and the responsibilities your agency will take on. With Managed Teams, discuss the ongoing support and how responsibilities are shared. Ask Staff Stack to confirm the terms, employment, payroll, management and review arrangements for your role before you choose, and compare them on the pricing page.
Frequently asked questions
What should a paid social media buyer own?
Decide this before you recruit. A buyer might own account structure, budgets, testing and weekly reporting, while a creative strategist owns angles and a client lead owns the relationship. Write down which decisions stay with a named person.
How do I test a media buyer before hiring?
Give every candidate the same redacted or fictional account export and ask for a one-page written audit. Score diagnosis, respect for what already works, a first-week test plan and honesty about what the data cannot show.
Should a media buyer trial be unpaid?
Acas, the UK workplace advisory body, says an unpaid work trial should be for a reasonable time, for example 2 hours or a shift, and not usually longer than one day. It says the minimum wage must be paid if the trial is not genuinely for recruitment. Rules differ by country, so check those that apply to you.
Who should own the ad accounts?
Your agency or the client should own the ad accounts, pixels and creative files, and the buyer should receive only the access their tasks need. Confirm the platform's own rules for sharing access before you grant it.
Should I choose Direct Hire or Managed Teams?
Compare the responsibilities and support your agency wants, then ask Staff Stack to confirm the terms of each arrangement for your role. Review pricing before you decide.
