The short version
An AI media buyer is a set of AI agents that watch your ad accounts, diagnose changes, pace budgets and draft reports, then propose changes for you to approve. Offload the monitoring, pacing, wasted-spend checks and reporting. Keep strategy, budget planning and creative direction.
1. The media buyer's week, task by task
Here is where the time goes, and how much of each task AI agents can take. Offload means an agent can do it end to end. Offload with approval means the agent prepares the work and you sign off. Keep means it stays with you.
| Task | AI agents? | How |
|---|---|---|
| Morning check across Meta, Google and the store | Offload | A scheduled daily brief flags what moved before you open a dashboard. |
| Diagnosing why ROAS or CPA moved | Offload | An agent traces the cause across campaigns, audiences, creative and landing pages. |
| Budget pacing and month-end forecasting | Offload with approval | Let the agent track pacing; approve any budget change it proposes. |
| Shifting budget between campaigns | Offload with approval | Keep on Ask until you've seen a few weeks of its reallocation calls. |
| Pausing wasted spend | Offload with approval | Low-risk pauses inside a spend threshold can move to Allow later. |
| Weekly performance report | Offload | A reporting agent refreshes numbers and writes what changed. |
| Quarterly plan, channel mix and targets | Keep | Agents inform the plan with data; the plan is yours. |
| Briefing creative and approving new tests | Keep | AI can draft the brief — you decide what the brand tests. |
2. What to offload to GoMarble AI Agents
Each of these is a GoMarble AI Agent you assign to a recurring job. The mode is what we'd start with — you can change it per action at any time.
Daily performance brief
Every weekday morning, summarises spend, revenue and efficiency across platforms and flags the movements that matter.
Start in: Read-only
Performance diagnostician
When ROAS or CPA moves outside your baseline, traces the cause and proposes a fix.
Start in: Ask
Budget pacer
Tracks spend against the monthly plan and proposes budget changes inside a cap you set.
Start in: Ask
Wasted-spend cleaner
Finds ad sets, placements and search terms spending without converting and proposes pauses or negatives.
Start in: Ask, then Allow under a spend limit
Allow lets the agent complete an action inside its scope and limits. Ask holds the change for your approval. Block stops it reaching the account. Read-only agents only analyse and report.

4. What AI can't do for a media buyer
Being clear about this is what makes the rest trustworthy.
Set the strategy
Which channels to scale next quarter, what CAC the business can afford, when to push for growth over efficiency — agents give you better inputs, not the answer.
Know what the platforms can't see
A stock-out, a price change, a PR moment or a competitor's sale moves performance in ways the ad data alone won't explain. You bring that context.
Fix broken tracking by itself
If conversion tracking is wrong, an agent will diagnose confidently from wrong numbers. Measurement is still a human responsibility.
Own the risk
A confident recommendation can still be the wrong move. Big budget shifts deserve your judgment and approval.
