How to Hire a Remote Media Buyer: Skills, Test Task and Red Flags

A good media buyer treats your ad budget like their own. A weak one spends it and sends a report. The difference shows up in the hiring process if you know what to look for.

What a media buyer does

A media buyer runs your paid advertising day to day. That means building campaigns, choosing audiences and keywords, setting bids and budgets, testing creatives and landing pages, and reporting what worked.

Daily attention is the point. Ad platforms change quickly, and a campaign checked once a week wastes money in between.

Skills that matter

• Platform depth. Real experience in the platform you spend on. Google Ads and Meta Ads need different skills.
• Numbers. They should be comfortable with cost per lead, return on ad spend and conversion rates, and know which one matters for your business.
• Testing habits. A clear method for testing one thing at a time.
• Tracking. They can check that conversions are measured correctly in tools like GA4.
• Plain reporting. They can explain results in two paragraphs, without jargon.

A simple test task

Ask shortlisted candidates to review an ad account, yours with read-only access or a sample, and answer three questions in writing:

1. What are the three biggest problems you see?
2. What would you change in the first week?
3. What would you test in the first month?

It takes about an hour, and it shows judgment better than any interview answer. Pay for the task if it uses your real account.

Interview questions worth asking

• "Tell me about a campaign that failed. What did you change?"
• "How do you decide when to stop an ad?"
• "What do you check first thing every morning?"
• "How would you split a small budget across platforms for a business like ours?"

Listen for specifics. Vague answers about "optimizing" usually mean shallow experience.

Red flags

• Guaranteed results. Nobody controls the ad auction.
• No questions about your margins or customer value.
• Reports full of impressions and clicks, with no mention of leads or sales.
• Asking to run ads from their own account instead of yours.

Keep ownership of your accounts

Always run campaigns in your own ad accounts and give the media buyer access. If they leave, every campaign, audience and learning stays with you. You can remove access in one click.

Freelancer, agency or full-time

A freelancer or agency splits attention across many clients. A full-time media buyer checks your accounts every day and learns your business in depth. For steady ad spend, full-time usually pays for itself.
