How to Choose a Paid Ads Agency: Ecommerce Scorecard

Choosing a paid ads agency should not depend on the most confident pitch, the largest claimed ROAS or the longest service list.

The right agency should understand the business model, protect account ownership, verify tracking, connect advertising to contribution profit and explain how decisions will be made when performance changes.

Use this scorecard to compare Meta Ads and Google Ads agencies consistently.

Define the business problem first

Before interviewing an agency, document what must improve.

Examples:

1. Acquisition is unprofitable
2. Meta creative testing is inconsistent
3. Google Shopping spends on weak products
4. Conversion tracking is unreliable
5. Brand revenue hides weak nonbrand performance
6. Reporting does not explain decisions
7. The team cannot scale without losing margin
8. Landing pages do not convert paid traffic
9. The current agency lacks ecommerce experience
10. The owner has no access to the advertising systems

A clear problem makes agency comparison more useful. A specialist in creative-led Meta acquisition may not be the best fit for a feed-heavy Google Shopping problem.

Share the correct business context

A serious agency should ask for more than platform screenshots.

Prepare:

1. Product margins
2. Average order value
3. Refund rate
4. New versus returning customer revenue
5. Bestselling products
6. Inventory constraints
7. Customer acquisition target
8. Repeat purchase behavior
9. Promotion calendar
10. Historic account changes
11. Website conversion rate
12. Creative production capacity

Use the agency handoff checklist to prepare access and data.

Score the initial audit

Ask each agency what it would review before changing the account.

A strong audit should include:

1. Conversion tracking
2. Platform and store reconciliation
3. Product-level profitability
4. Campaign roles
5. Search terms
6. Product feed
7. Creative concepts
8. Audience structure
9. Landing pages
10. Inventory
11. Budget and bidding history
12. New customer quality

Weak answer:

“We will optimize campaigns and scale winners.”

Stronger answer:

“We will first verify purchase tracking, calculate product-level targets, separate brand from nonbrand demand, review search terms and item-level spend, then prioritize the largest supported profit opportunity.”

Ask how success will be measured

Platform ROAS alone is not enough.

A useful measurement plan may include:

1. Contribution profit
2. New customer CPA
3. New customer ROAS
4. Blended marketing efficiency
5. Product-level ROAS
6. Conversion rate
7. Average order value
8. Repeat customer value
9. Refund rate
10. Revenue and profit against plan

The exact metrics should match the business model.

Use the weekly paid ads reporting framework as a reporting reference.

Ask for decision examples

Request examples of how the agency decides to:

1. Scale a campaign
2. Hold a campaign
3. Reduce budget
4. Pause an ad
5. Exclude a product
6. Add a negative keyword
7. Change Target ROAS
8. Replace creative
9. Test a new market
10. Fix tracking

The answer should include thresholds, time windows and business context. Avoid agencies that present every decision as a secret method.

Evaluate Meta Ads capability

For Meta Ads, ask how the agency handles:

1. Creative research
2. Customer angles
3. Hooks and concepts
4. Creator briefs
5. Static, video and catalogue formats
6. Creative testing budget
7. New customer reporting
8. Broad, interest and lookalike decisions
9. Creative fatigue
10. Landing page alignment
11. Scale decisions
12. Pixel and Conversions API health

The agency should treat creative as a repeatable system, not wait for the client to send random assets.

Ask who is responsible for production. A strategy without creative capacity may not improve performance.

Evaluate Google Ads capability

For Google Ads, ask how the agency handles:

1. Brand and nonbrand separation
2. Search term reviews
3. Negative keywords
4. Match types
5. Product feed optimization
6. Merchant Center diagnostics
7. Product-level profitability
8. Performance Max and Shopping structure
9. Target ROAS decisions
10. Budget and auction analysis
11. Conversion goals
12. Enhanced conversions

A strong ecommerce Google Ads agency should be able to discuss item IDs, margin tiers and feed quality, not only campaign totals.

Evaluate tracking capability

Ask who owns measurement when numbers disagree.

The agency should be able to investigate:

1. Meta Pixel
2. Conversions API
3. Google Ads purchase tracking
4. GA4 ecommerce events
5. Enhanced conversions
6. Tag Manager when used
7. Shopify order data
8. Duplicate purchases
9. Currency and value errors
10. Attribution differences

The answer should not be “the platforms never match” without a reconciliation process.

Read the Meta versus Google attribution guide for the questions the agency should address.

Review account ownership

The business should own or control:

1. Meta Business Portfolio
2. Meta ad account
3. Facebook Page and Instagram account
4. Pixel and dataset
5. Google Ads account
6. Merchant Center
7. GA4 property
8. Tag Manager container
9. Search Console
10. Shopify or ecommerce platform access
11. Creative source files
12. Reporting dashboards

The agency should receive partner or user access. It should not require the client to build the business inside an account the agency owns.

Ask what happens to campaigns, tracking and creative files when the relationship ends.

Review communication

Clarify:

1. Main contact
2. Actual account operator
3. Reporting schedule
4. Meeting schedule
5. Response expectations
6. Emergency process
7. Change approval process
8. Creative feedback process
9. Access to change logs
10. How bad news is communicated

A polished salesperson may not be the person managing the account. Ask to meet the strategist or buyer responsible for decisions.

Review reporting quality

A useful report should answer:

1. What happened?
2. Why did it happen?
3. Is tracking reliable?
4. Which products or campaigns caused the result?
5. How did profit compare with target?
6. What changed?
7. What will happen next?
8. What does the client need to provide?

A dashboard without interpretation is not strategy.

Review pricing and contract terms

Compare:

1. Monthly retainer
2. Percentage of spend
3. Setup fee
4. Creative production cost
5. Landing page cost
6. Tracking cost
7. Minimum term
8. Notice period
9. Scope limits
10. Additional account fees

The cheapest fee can become expensive when weak decisions waste media spend. The most expensive agency is not automatically the strongest.

Pricing should be clear enough to compare total expected cost.

Ask about conflicts and capacity

Ask:

1. How many accounts does each strategist manage?
2. Does the agency work with direct competitors?
3. Who covers holidays or absences?
4. Is work outsourced?
5. Who creates ads and landing pages?
6. How quickly can tracking problems be investigated?
7. How many active tests can the team support?

Capacity affects attention and execution speed.

Red flags

Be cautious when an agency:

1. Guarantees a specific ROAS
2. Avoids discussing margins
3. Refuses account ownership
4. Uses one target for every product
5. Reports only platform revenue
6. Cannot explain attribution differences
7. Rebuilds accounts before auditing tracking
8. Uses the same structure for every client
9. Hides the actual account manager
10. Has no creative process for Meta
11. Has no feed process for Google Shopping
12. Cannot explain when it would pause spending
13. Requires a long contract before sharing the plan
14. Uses competitor logos or results without context
15. Treats every weak result as a need for more budget

Positive signals

Look for an agency that:

1. Asks for contribution margin
2. Verifies tracking first
3. Separates brand and nonbrand
4. Reviews products individually
5. Documents decisions
6. Uses several reporting windows
7. Explains risk clearly
8. Connects creative with landing pages
9. Protects client ownership
10. Admits uncertainty
11. Sets test budgets and stop-loss rules
12. Reports what did not work
13. Understands inventory and cash flow
14. Gives the client clear responsibilities
15. Builds a plan around the actual business

Weighted scorecard

Score each area from 1 to 5.

Multiply each score by the weight. Do not let a strong sales presentation outweigh weak tracking, ownership or profit understanding.

Final decision process

1. Define the business problem
2. Share accurate context
3. Compare initial audit approaches
4. Score measurement quality
5. Review Meta and Google capabilities separately
6. Confirm tracking ownership
7. Confirm account ownership
8. Review communication and capacity
9. Compare full cost and contract terms
10. Use the weighted scorecard
11. Check references with similar business models
12. Choose the strongest operating fit, not the strongest pitch

Final principle

A paid ads agency should improve the quality of decisions, not only operate the platforms.

Choose the team that understands profit, tracking, products, creative and customer acquisition as one system. Clear ownership, honest reporting and documented decision rules are more valuable than guaranteed outcomes.
