Facebook Ads Agency Guide: Selection and Account Ownership
Account ownership matters just as much here as for Google Ads — plus a creative-testing track record that matters more on Meta than almost anywhere else.

Quick Answer
Business Manager Ownership
Just as with Google Ads, if an agency creates and controls your Meta Business Manager, Pixel, and page, switching agencies later risks losing Pixel data history, custom audiences, and page control built up over time. Insist on your own Business Manager account with the agency added as a partner from day one.
Evaluating Creative Expertise
| What to check | Why it matters |
|---|---|
| Track record of testing genuinely different angles | Meta performance depends heavily on creative variety, not just targeting |
| Process for detecting creative fatigue | Frequency/CTR monitoring is a core, ongoing task on Meta, not a one-time setup |
| Format range (Feed, Stories, Reels) | Native, format-specific creative outperforms one-size-fits-all assets |
Ask specifically how the agency uses Advantage+ automation versus manual campaign structure — a capable agency should be able to explain when they let Meta's automation run broadly versus when they intervene with manual audience or placement controls, and why. "We just use Advantage+ for everything" is a simpler answer than the situation usually warrants.
Questions to Ask
- "How do you decide when creative needs to be refreshed?"
- "Can you show examples of genuinely different creative angles you've tested for a past client?"
- "Who will own the Business Manager account, Pixel, and page?"
- "How do you build and refresh lookalike audiences over time?"
Variations by Business Type
| Business type | What to prioritize in an agency |
|---|---|
| Ecommerce | Retargeting and cart-abandonment expertise, product feed integration |
| Lead generation | Lookalike-building expertise from qualified leads specifically |
| Visual/lifestyle brands | Strong native creative production, especially for Reels |
Case Study
A business hired a Facebook Ads agency that built strong initial results but never refreshed creative over several months, letting frequency climb well past healthy levels without proactive action. Performance quietly declined, and when the business raised it, the agency had no clear process for detecting or responding to fatigue — reactive only after results had already visibly dropped. Switching to an agency with an explicit fatigue-monitoring process brought performance back to previous levels within a few weeks of onboarding.
Decision Matrix
| Agency response | Interpretation |
|---|---|
| Insists on their own Business Manager | Red flag — insist on your own account instead |
| No clear process for creative refresh/fatigue | Concerning — ask for specifics before signing |
| Can show genuinely varied past creative work | Good sign of real creative capability |
Common Mistakes
- Allowing the agency to own the Business Manager, Pixel, or page instead of you.
- Not evaluating creative testing track record specifically, focusing only on targeting expertise.
- Accepting reactive-only creative refresh instead of a proactive fatigue-monitoring process.
- Not asking how lookalike audiences will be built and refreshed over time.
Troubleshooting
Agency resists granting Business Manager ownership: treat this the same as a Google Ads agency refusing account ownership — a serious red flag.
Performance has quietly declined over months: ask specifically about frequency and creative refresh cadence before assuming targeting is the problem.
Checklist
☐ Your own Business Manager owns Pixel, ad account, and page
☐ Agency has a clear, proactive creative refresh process
☐ Past creative work shown demonstrates genuine variety
☐ Lookalike-building and refresh process explained clearly
FAQ
Who should own the Meta Business Manager account?
You should — the agency is added as a partner to your own account, not the reverse.
What creative expertise should an agency demonstrate?
A track record of testing genuinely different angles and a clear fatigue-detection process.
How is this different from evaluating a Google Ads agency?
Ownership and transparency checks are the same, but creative testing and fatigue management matter more heavily on Meta.
Fatigue monitoring shouldn't depend on an account manager remembering to check.
