What is a media buyer?
A media buyer buys and manages paid advertising on platforms such as Meta, Google, TikTok and Snapchat. The job is to hit the business goal, whether sales, leads or installs, at the lowest cost possible.
It differs from a content creator or social media manager: a media buyer doesn't write the daily posts but manages the paid budget and answers for its numbers.
What does a media buyer do each day?
- Planning: splitting the budget between platforms and campaigns by goal.
- Building: creating campaigns and audiences, and briefing the creative team.
- Monitoring: checking cost per result daily, pausing what wastes budget and scaling what works.
- Testing: trying new audiences, ads and offers all the time.
- Reporting: explaining results to the client or management in terms they understand.
The skills that make the difference
- Reading numbers: knowing which number calls for a decision and which is noise.
- Understanding tracking: someone who can't trust their data makes wrong decisions with confidence.
- Judging creative: knowing why one ad worked and another failed, and asking for the next version.
- Discipline: not touching a campaign before there is enough data.
- Business sense: margin and customer value set the acceptable cost, not market averages.
A media buyer's tools: the essentials
Ad platforms. Each platform's own manager: Meta Ads Manager, Google Ads, TikTok Ads Manager and Snapchat Ads Manager, plus LinkedIn Campaign Manager for B2B.
Tracking. Google Tag Manager to install tags without editing the site, each platform's pixel, and server-side conversion APIs (such as the Conversions API) to recover what the browser loses.
Analytics. Google Analytics 4 to see what visitors do after the click, and Google Search Console for organic traffic.
Reporting. Spreadsheets for daily maths, and ready dashboards that combine platforms for clients.
Research. The public ad libraries on Meta, TikTok and LinkedIn to see what competitors run, and Keyword Planner in Google Ads.
Where does a media buyer's time go?
Ask any media buyer with more than one client and you'll hear that most of the day goes on moving around, not deciding: opening account after account, exporting report after report, copying numbers into a sheet, then doing it again for each platform.
The decision itself, pause this and scale that, takes minutes. Getting to the numbers that allow the decision is what takes the hours.
AI in a media buyer's work
The common use is writing ad copy and video ideas. The newer one is connecting the assistant to your ad accounts themselves over the MCP protocol: you ask where spend went without results this week, it answers from account data, then makes the change once you approve.
That is what Go Shift does: it connects Meta, Google, Snapchat and TikTok to ChatGPT and Claude, with a folder per client and a report that combines their platforms. Its rule is that anything that raises spend needs your confirmation. It doesn't replace a media buyer's experience; it gives back the time to use it.
How to get started in the field
- Learn one platform well before moving to the next. Meta or Google is a good start.
- Understand tracking from day one: pixels, events and Google Tag Manager.
- Manage a real budget, even a small one. Nothing teaches like money being spent in front of you.
- Document your results in numbers; they are your real CV.
