Questions to ask a social media marketing agency can save you months of wasted spend, unclear reporting, and content that does not move the business. Before you sign a contract, you want proof of process, realistic benchmarks, and clean measurement that ties to your goals. In practice, the best agencies are not the ones with the loudest pitch deck – they are the ones who can explain exactly how they plan, execute, and learn. This guide gives you a structured set of questions, plus decision rules and sample calculations you can use in the sales call. You will also get tables you can copy into your evaluation doc so your team can compare agencies fairly.
First, get specific about what you are buying. Many disappointments come from mismatched expectations: you thought you were hiring for growth, while the agency thought you wanted pretty posts. So begin with goals, scope, and constraints, then force clarity on what success looks like in 90 days. A strong agency will ask you hard questions back and will not promise overnight results. If they jump straight to follower counts, treat that as a warning sign.
- What is the primary objective for the next 90 days? Ask them to choose one: awareness, consideration, lead gen, sales, retention, or community health.
- Which platforms are in scope and why? Require a rationale tied to your audience and creative strengths, not just what is trending.
- What deliverables are included each month? Get counts for posts, Stories, Reels, Shorts, community management hours, and reporting.
- What is out of scope? Examples: influencer sourcing, paid media buying, UGC licensing, customer support, or video production.
- What does a realistic 90 day win look like? Listen for measurable outcomes and a plan to iterate, not vague “brand lift.”
Takeaway: If you cannot write the scope in one paragraph after the call, you are not ready to compare proposals.
Define the metrics early (and make them explain the math)
Next, align on measurement terms so you do not argue later. Agencies sometimes hide behind vanity metrics because they are easy to show and hard to dispute. Instead, ask for definitions, data sources, and how each metric connects to your funnel. You should also confirm whether they report on organic only, paid only, or blended performance. Finally, ask how they handle attribution limits, especially on iOS and in-platform checkout.
Key terms (plain English):
- Reach – unique people who saw your content.
- Impressions – total views, including repeat views by the same person.
- Engagement rate – engagements divided by reach or impressions (you must specify which).
- CPM – cost per 1,000 impressions. Formula: CPM = (Spend / Impressions) x 1000.
- CPV – cost per view (usually video views). Formula: CPV = Spend / Views.
- CPA – cost per acquisition (lead, signup, purchase). Formula: CPA = Spend / Conversions.
- Whitelisting – running ads through a creator or partner handle (also called “spark” on TikTok in some contexts).
- Usage rights – permission to reuse content (where, how long, and in what formats).
- Exclusivity – restrictions on working with competitors for a period of time.
Questions to ask:
- Do you calculate engagement rate by reach or impressions, and why?
- What is your reporting source of truth – native platform analytics, GA4, a BI tool, or all three?
- How do you separate content performance from paid distribution effects?
- Which KPIs are leading indicators vs lagging indicators for our business?
Example calculation: If you spend $3,000 promoting content that generates 250,000 impressions, your CPM is (3000 / 250000) x 1000 = $12 CPM. If that same spend produces 120 purchases, your CPA is 3000 / 120 = $25 CPA. Ask the agency which number they will optimize for and what tradeoffs they expect.
Takeaway: Require a one page KPI map that shows each metric, its formula, and the decision it informs.
Strategy and creative process: how they actually build content that works
Then, dig into how the agency turns insights into posts. A good strategy is not a mood board; it is a repeatable system for testing hooks, formats, and offers. Ask how they research your audience, how they learn from competitors, and how they translate findings into a weekly plan. You also want to know who writes, who shoots, and who edits, because “we do creative” can mean anything from templates to full production. If influencer marketing is part of your plan, ask how they coordinate creators with your brand voice and compliance needs.
- What is your content testing framework? Look for a clear cadence: hypothesis, creative variants, measurement window, and next action.
- How do you develop hooks and scripts? Ask for 3 recent examples of hook iterations and what changed.
- What is your creative review process? Confirm number of revisions, turnaround times, and who approves.
- How do you handle brand voice and claims? This matters for regulated categories and for avoiding misleading before and after content.
- What is your plan for community management? Ask how they respond to product questions, complaints, and spam.
To keep your evaluation grounded, ask them to walk through one of your existing posts and explain what they would change. You will learn quickly whether they can diagnose performance or if they only talk in generalities. For more practical examples on how marketers evaluate creator and content performance, you can browse the InfluencerDB.net blog guides and templates and compare their approach to what you hear in the pitch.
Takeaway: Choose the agency that can explain a weekly creative loop, not just a quarterly “strategy.”
Reporting, experimentation, and accountability (what happens after month one)
After the honeymoon month, results depend on how fast the agency learns. Therefore, you should ask exactly how they run experiments and what they do when performance stalls. You also want to know how often you will meet, what is in the report, and whether you will get raw data access. If they cannot describe a postmortem process, they may not have one.
- What is your reporting cadence? Weekly performance pulse plus a monthly deep dive is common.
- What is included in the report? Require: top content, bottom content, why it happened, and what changes next.
- How do you set benchmarks? Ask whether they use your historical data, industry ranges, or both.
- How do you document tests? Look for a test log with hypothesis, variables, and outcomes.
- Who owns results? Clarify what the agency controls (creative, posting, moderation) vs what you control (offer, pricing, site conversion).
| Report section | What you should see | Decision it enables |
|---|---|---|
| Content leaderboard | Top 10 posts with reach, watch time, saves, shares, CTR | Double down on formats and topics that drive intent |
| Creative diagnostics | Hook retention, drop off points, caption and CTA notes | Rewrite scripts and tighten first 3 seconds |
| Audience insights | Follower growth sources, active hours, geo, interests | Adjust posting schedule and targeting |
| Experiment log | Hypothesis, variant A/B, sample size, outcome | Scale winners and stop losers quickly |
| Business outcomes | Leads, sales, CPA, assisted conversions (if available) | Budget allocation and forecasting |
Takeaway: If the report does not tell you what to do next week, it is not a performance report.
Pricing, contracts, and what you really pay for
Agency pricing is often a mix of retainers, production fees, and paid media management. To compare proposals, you need to separate labor from pass-through costs and understand what triggers extra charges. Ask for a line item breakdown and a sample invoice. Also confirm contract length, termination terms, and whether you own the creative files. If the agency works with creators, you must clarify usage rights and exclusivity because those can change costs dramatically.
- Is your fee a retainer, project fee, or performance based? Performance based sounds attractive, but define the metric and attribution rules.
- What is included in the retainer? Strategy, posting, editing, community management, reporting, and meetings should be explicit.
- What are pass-through costs? Paid spend, creator fees, music licensing, and tools should be billed transparently.
- What are the contract terms? Length, renewal, termination notice, and kill fees.
- Who owns assets and usage rights? Confirm whether you can repurpose content into ads and for how long.
| Cost component | Typical pricing model | Questions to ask |
|---|---|---|
| Strategy and account management | Monthly retainer | How many hours and who is assigned (senior vs junior)? |
| Content production | Included up to a cap or priced per asset | How many videos per month, and what counts as a revision? |
| Community management | Hourly or tiered packages | Response time SLA, escalation process, weekend coverage? |
| Paid social management | % of spend or flat fee | What is the testing plan, and do we get ad account access? |
| Creator partnerships | Per creator fee plus agency sourcing fee | How do you price usage rights, whitelisting, and exclusivity? |
For disclosure and endorsement risk, insist that the agency follows clear rules for sponsored content. The FTC’s endorsement guidance is a solid baseline – review it and ask how they operationalize it in briefs and approvals: FTC Endorsements, Influencers, and Reviews.
Takeaway: Compare agencies using an “all in monthly cost” view that includes retainers, estimated production overages, and paid management fees.
Influencer and paid amplification questions (if they offer it)
Many social agencies now bundle influencer marketing and paid amplification. That can work well, but only if they have a clear sourcing method, fraud checks, and a plan for turning creator content into performance creative. Ask how they choose creators, how they negotiate usage rights, and how they track results across posts and ads. You should also confirm whether they run ads from your brand handle or via whitelisting, because that affects creative approvals and reporting. Finally, ask how they prevent overexposure and audience fatigue when boosting the same assets.
- How do you source and vet creators? Require checks for audience fit, past brand work, and suspicious engagement patterns.
- What is your creator brief template? It should include do and do not, claims guidance, and deliverables.
- How do you handle whitelisting? Ask who owns the ad account, who sets targeting, and how long access lasts.
- How do you price usage rights and exclusivity? Get it in writing: channels, duration, and territories.
- How do you measure incrementality? Even a simple holdout test beats guessing.
If they manage Meta ads, ask them to show how they structure campaigns and naming conventions, and how they handle pixel and Conversions API setup. Meta’s own documentation can help you sanity check what you hear: Meta Business Help Center.
Takeaway: Do not accept “we have creators” as a plan – require a repeatable vetting and measurement workflow.
Common mistakes when hiring an agency (and how to avoid them)
Even experienced teams fall into predictable traps. The first is hiring based on aesthetics alone, which often leads to content that looks nice but does not earn attention. Another common mistake is accepting a report full of screenshots instead of a narrative with decisions and next steps. Teams also underestimate the time needed from internal stakeholders, so approvals drag and momentum dies. Finally, many contracts fail to define ownership and usage rights, which becomes expensive when you want to turn organic winners into ads.
- Mistake: Optimizing for follower growth only. Fix: Tie goals to reach, clicks, leads, or sales depending on your funnel.
- Mistake: Vague deliverables. Fix: List counts, formats, and revision limits in the SOW.
- Mistake: No experiment plan. Fix: Require a monthly test roadmap with 3 to 5 hypotheses.
- Mistake: No data access. Fix: Ensure you retain admin access to ad accounts and analytics.
- Mistake: Ignoring compliance. Fix: Build disclosure checks into the approval workflow.
Takeaway: If you cannot explain how the agency will learn and improve, you are buying output, not outcomes.
Best practices: a simple evaluation scorecard you can use today
To finish, turn the conversation into a decision. A scorecard keeps you from choosing the best storyteller instead of the best operator. Use the categories below, score each 1 to 5, and require evidence for every score. In addition, ask for two client references where the agency handled a similar budget and similar constraints. When you do reference checks, ask what went wrong and how the agency responded.
- Strategy clarity: Can they articulate a 90 day plan with priorities and tradeoffs?
- Creative system: Do they have a repeatable process for testing hooks and formats?
- Measurement rigor: Are definitions, formulas, and data sources clear?
- Operational fit: Do timelines, approvals, and communication match your team?
- Commercial fairness: Are fees transparent, and are usage rights and exclusivity defined?
Decision rule: If an agency scores under 4 on measurement rigor or operational fit, do not sign a long contract. Start with a short pilot, define success criteria, and renegotiate only after you see their learning loop in action.
Takeaway: The best hire is the agency that can show its work – strategy, creative, and reporting – in a way your team can audit.
