 What to Expect When You Hire a Digital Marketing Agencyhttps://topposition.com/blog/hiring-a-digital-marketing-agency/ | 1.3% |
Hiring a great PPC agency when your current spend isn't performing requires shifting from a generic search to a rigorous, diagnostic vetting process. A great agency won't just optimize bids; they will audit your funnel, fix tracking, and tie every dollar to revenue.
Here is how a Digital Marketing Manager can successfully source, vet, and hire a top-tier PPC partner:
To help narrow this down, could you share:
I can give you a tailored list of interview questions to ask these agencies.
No sources cited
If your digital ad spend isn't showing ROI, I’d make the agency-selection process less about “Who is the best PPC agency?” and more about “Who can prove they can connect ad spend to profitable business outcomes?”
Here’s the framework I’d use as a Digital Marketing Manager.
A great PPC agency should start by asking how you define revenue, not by promising to lower CPC.
Before they touch campaigns, they should understand:
This is critical because bad conversion tracking can make a terrible campaign look profitable—or a good campaign look terrible. Google itself emphasizes the importance of correctly configured conversion actions and goals for optimization.
Interview question:
“Walk me through exactly how you would determine whether our PPC-generated leads are profitable.”
If they immediately start talking about CTR, impressions and Quality Score, keep interviewing.
Give shortlisted agencies read-only access to your existing account and ask for a paid-media diagnostic.
Have them identify:
The best agencies should be willing to tell you “don't spend more yet.”
That's a particularly good signal when you're already struggling to demonstrate ROI.
Don't be impressed by a case study saying:
“We increased conversions 147%.”
Ask:
“What was the starting point, how much was spent, what constituted a conversion, what happened to those leads, and what was the resulting CAC/ROAS?”
Ideally, find 2–3 clients with similar economics, sales cycle, geography and average order/customer value.
Ask to speak to those clients.
I'd score candidates roughly like this:
| Criterion | Weight |
|---|---|
| Ability to connect PPC → qualified leads/revenue | 25% |
| Measurement & attribution expertise | 20% |
| Strategic thinking/account diagnosis | 20% |
| Relevant proven results | 15% |
| Communication/reporting | 10% |
| Pricing/contract terms | 10% |
That prevents the cheapest agency or slickest salesperson from winning.
This is non-negotiable.
Your company should retain ownership/control of:
The agency should be a manager/partner, not the owner of your marketing history.
Google recommends individual user access, appropriate permission levels and regular access reviews rather than shared credentials.
Suppose you spend $100k/month.
An agency charging 15% of spend makes $15k if you spend $100k—and $30k if you spend $200k.
That's not automatically bad, but you should ask:
“Why does your compensation structure encourage increasing spend rather than increasing profitable revenue?”
A flat fee or a hybrid base + performance component can sometimes align incentives better.
More important than the exact pricing model is whether the agency is accountable for the metrics that matter to your CFO.
Don't accept:
“We'll optimize campaigns and improve performance.”
Ask them to describe what they expect to accomplish in:
Days 1–30
Days 31–60
Days 61–90
And ask:
“What would cause you to recommend reducing our spend?”
A good agency will have a real answer.
Your monthly dashboard shouldn't be a celebration of clicks.
I'd want something like:
Spend → Leads → Qualified Leads → Opportunities → Customers → Revenue → Gross Profit
Then:
If the agency can't get reasonably close to this, your organization may have a measurement problem before it has a PPC problem.
This is probably my favorite hiring test.
Give 3 agencies identical information and ask:
“Here is our current PPC performance. You have 30 minutes. Tell us what you think is wrong, what you would investigate first, and where you would put the next $50,000.”
Don't judge them on whether their diagnosis is perfect.
Judge them on how they think.
A strong candidate will ask uncomfortable questions:
A mediocre agency will tell you how many clicks they can generate.
🚩 Guarantees a specific ROAS before auditing the account
🚩 Talks mostly about clicks/impressions
🚩 Can't explain conversion tracking clearly
🚩 Won't show real case studies
🚩 Wants to own your advertising account
🚩 Won't provide transparent access
🚩 Gives you a generic strategy deck
🚩 Has a different “specialist” every time you call
🚩 Wants to increase budget before establishing profitability
🚩 Can't explain what happens when performance deteriorates
🚩 Reports conversions without asking whether those conversions become customers
If I could ask only one question in the pitch, I'd ask:
“If you took over our account tomorrow, what are the first five things you'd investigate—and what evidence would make you change your mind?”
Then stop talking.
The quality of their questions is often more revealing than the quality of their pitch.
And given that you're already seeing poor ROI, I would not hire an agency to “manage PPC” yet. I'd run a competitive process specifically for a PPC + measurement + profitability partner. That distinction can save you from simply paying a new agency to optimize the wrong numbers.
If your digital ad spend isn't showing ROI, don't hire an agency to “run Google Ads.” Hire one to own a measurable revenue-acquisition problem.
Google itself recommends using conversion tracking to connect ad clicks to actual sales/signups and calculate ROI—not relying on clicks, impressions, or CPC alone.
Give every agency the same targets:
For B2B, don't accept “cost per lead” as the north-star metric if half the leads never become pipeline.
Before an agency proposes campaigns, ask:
“Walk me through how you'd reconcile Google Ads conversions with our CRM revenue.”
A strong agency should discuss conversion validation, duplicate/misclassified conversions, CRM/offline conversion data, attribution limitations, and ongoing QA.
This matters because bad tracking can make a good campaign look bad—or cause an agency to optimize toward worthless leads.
Don't ask them for a generic 30-slide pitch. Give the finalists read-only access and ask for:
A credible onboarding process should begin with an audit and tracking validation rather than immediately rebuilding everything.
Ask:
You're buying expertise and decision-making, not a logo or a beautiful proposal.
Your company should retain ownership/control of:
Google specifically advises advertisers to understand their third-party partners and says advertisers should have visibility into advertising costs and performance.
If an agency says, “Our account is proprietary; we'll give you reports,” that's a major red flag.
Be skeptical of pitches centered on:
“We increased CTR 42%.”
“Quality Score is now 9.”
“We cut CPC by 30%.”
Those can be useful diagnostic signals, but they aren't business outcomes. Google explicitly describes Quality Score as a diagnostic tool rather than a KPI.
The agency should be able to say:
“We spent $X → generated Y qualified opportunities → Z became customers → producing $N revenue at $M CAC.”
A great PPC agency should be comfortable killing campaigns, keywords, audiences and creative that aren't producing economic value.
Ask:
“Tell me about a time you recommended spending less money for a client.”
The answer is revealing. A performance agency should optimize the marginal return on the next dollar, not simply try to spend your entire budget. Google's guidance similarly emphasizes allocating more budget to campaigns that perform better against business goals.
I'd score finalists roughly like this:
| Criterion | Weight |
|---|---|
| Proven results in your business model | 20% |
| Measurement/tracking expertise | 20% |
| Strategic thinking & audit quality | 20% |
| Quality of assigned team | 15% |
| Transparency/account ownership | 10% |
| Testing/optimization methodology | 10% |
| Price | 5% |
Don't make price the deciding factor. A $10k/month agency that lowers CAC substantially can be cheaper than a $3k/month agency that burns $50k in media.
Give 3–5 agencies the same brief and the same limited account information, then compare their diagnoses—not their sales pitches. Three to five is also a reasonable evaluation set cited by current PPC-agency selection guidance.
The winner should be the team that can most convincingly explain:
“Here's where your money is leaking, here's what we'd measure, here's what we'd change first, here's how we'd know it worked, and here's what we'd do if it didn't.”
And given that you're already seeing poor ROI, I'd make tracking/revenue attribution the first gate. You may discover that the problem isn't the PPC agency at all—it's that your current measurement system can't distinguish clicks from economically valuable customers.
To hire a great PPC agency that turns around your ROI, a digital marketing manager must shift from judging agency sales pitches to auditing their technical execution, tracking setup, and business alignment.
Before interviewing agencies, ensure your own data is accurate so you can hold them accountable.
Eliminate agencies that use outdated, vanity-metric strategies that do not impact your bottom line.
Interview the specific account managers who will do the daily work, not just the senior sales team.
A great agency acts as a growth partner, looking at your entire marketing funnel rather than just the ad platforms.
| Evaluation Area | What a Poor Agency Does | What a Great Agency Does |
|---|---|---|
| Landing Pages | Sends traffic to your existing homepage. | Builds dedicated, conversion-optimized landing pages. |
| Reporting | Sends an automated PDF summary of clicks once a month. | Provides a live dashboard mapped directly to your CRM pipeline revenue. |
| Budgeting | Recommends spending more money to fix poor performance. | Optimizes existing waste before scaling the ad budget. |
Protect your budget by setting up a transparent, performance-oriented contract structure.
If you'd like to narrow this down, let me know:
I can give you a tailored list of interview questions or specific agency red flags for your niche.
Hiring a high-performing PPC agency can turn unprofitable ad spend around, but vetting them requires looking past flashy sales pitches. Here is a step-by-step framework for a Digital Marketing Manager to find, evaluate, and hire a great PPC agency:
If you'd like to narrow this down, tell me:
I can give you a tailored list of red flags to watch out for during the agency pitches.
If your digital ad spend “isn’t showing ROI,” I’d hire the agency that treats measurement as the first problem to solve—not the agency that promises to optimize CPCs.
Here’s how I’d approach the selection as a Digital Marketing Manager:
A strong PPC agency should start by asking:
This is critical because Google itself positions conversion measurement as the basis for understanding ROI and optimizing bidding. For lead-generation businesses, Google recommends enhanced conversions for leads/offline conversion approaches to connect ad clicks with what happens later in the sales process.
Interview question:
“Walk me through how you would determine whether our PPC is generating profitable customers, not merely conversions.”
A great agency will want to see your CRM and sales data—not just your Google Ads account.
Give each finalist the same information and ask for an initial hypothesis.
They should identify things like:
Don't expect them to give away a complete strategy for free. You're looking for how they think.
The best response sounds like:
“Your reported CPA looks good, but 40% of your conversions appear to be low-value leads. Before we increase spend, we'd fix the conversion hierarchy and feed qualified/closed outcomes back into Google.”
That's much more valuable than:
“We'll lower your CPC by 20%.”
Make them define the KPI hierarchy.
For example:
Business KPI:
Revenue / gross profit / qualified pipeline
↓
Marketing KPI:
ROAS, MER, CAC, qualified-lead CPA
↓
Channel KPI:
Conversion rate, impression share, CPC, CTR
CPC and CTR are diagnostic metrics, not necessarily business outcomes.
If an agency leads its pitch with impressions, clicks and CTR but can't explain how those metrics translate into profit, I'd be cautious.
Ask these questions directly:
Google recommends separating funnel stages into distinct conversion actions—for example, lead, qualified lead and closed lead—so reporting and bidding can distinguish the stages.
Also, you should retain ownership of the advertising accounts. The agency should be a user/manager of your account, not the owner of your digital assets. Google provides different account access levels, including admin, standard and read-only, so there's no reason you should surrender control.
This is a huge differentiator.
Ask:
“Who is doing the work I am being sold?”
Then get the names/roles of:
Ask how many accounts that person manages.
You don't want a senior strategist dazzling you during the sales process and then disappearing after the contract is signed.
Don't just ask:
“Do you have case studies?”
Ask:
“Show me a client with a similar sales cycle, average order value, monthly spend and conversion problem.”
Then ask:
Be skeptical of “we increased conversions 300%” without revenue context.
I generally prefer a model that doesn't create perverse incentives.
Be cautious if an agency's compensation means they make more money simply by convincing you to spend more.
Ask about:
You want the incentives to be aligned with profitable growth, not maximum spend.
For your final 2–3 agencies, give each the same brief:
“Our PPC spend is $X/month. We currently report Y conversions at $Z CPA, but we're not confident those conversions translate into revenue. Our average customer is worth $A and our sales cycle is B days. What would you investigate first, and what would your first 90 days look like?”
Score their responses on:
| Criterion | Weight |
|---|---|
| Measurement/attribution expertise | 25% |
| PPC strategy | 20% |
| Understanding of your business economics | 15% |
| Technical execution | 15% |
| Team quality | 10% |
| Reporting/transparency | 10% |
| Price | 5% |
I'd deliberately make price only 5%. A cheap agency that wastes $100k is much more expensive than a good agency that charges $10k to manage a profitable $100k budget.
Walk away—or at least investigate heavily—if an agency:
Don't ask the agency to prove that your current PPC is profitable. Ask them to prove whether it is measurable.
If your current tracking is broken, an agency could make the campaigns dramatically better and your dashboard could still tell you they're failing—or vice versa.
Google's current tooling also matters here: as of June 15, 2026, Google has moved offline-conversion and enhanced-lead-conversion uploads toward its Data Manager API, so I'd specifically ask prospective agencies how their measurement stack handles the current implementation.
Bottom line: hire the agency that can say, “Before we spend another dollar, here's how we'll establish which dollars create profitable customers, here's what we're going to test, and here's how you'll independently verify our results.” That's the mindset I'd prioritize over a flashy PPC “growth” pitch.
If your digital ad spend isn’t showing ROI, I’d treat the agency search as a measurement + performance problem, not simply a “find someone who can run Google Ads” exercise.
A great PPC agency should be able to connect ad spend → qualified leads/sales → revenue → profit, not just report clicks, impressions, CTR, or even low CPL. Google itself recommends measuring conversions and ROI against the actual financial impact of advertising.
Give every agency the same business targets:
For example, don't say “We need more leads.” Say:
“We can pay up to $300 for a qualified opportunity, and our sales team closes 25% of qualified opportunities at an average gross profit of $4,000.”
That immediately changes the kind of agency you attract.
Don't accept a generic pitch deck.
Give finalists read-only access to the relevant advertising/analytics data and ask each agency to present:
“Here are the three biggest things you would change in our first 90 days—and why.”
A strong agency should identify things such as:
You want to see diagnosis before prescription.
This may actually be your biggest problem.
Ask:
“How will you determine whether a lead generated by Google became actual revenue?”
The agency should be comfortable with your analytics, CRM, offline conversion data, attribution, and conversion tracking—not just the Google Ads interface.
For lead-generation businesses, I'd specifically ask how they will distinguish:
click → lead → qualified lead → opportunity → closed customer → revenue.
Google's current tooling also supports enhanced-conversion implementations, so a sophisticated agency should be able to explain whether and how that fits your measurement setup.
It's a useful credibility check, but it isn't proof that an agency will make your business profitable.
Google's current Partner requirements include performance, spend, and certification criteria; for example, Partners need at least a 70% optimization score at the manager-account level, along with other requirements.
But notice what that doesn't tell you: whether they can generate profitable customers for your particular business.
Ask for:
You can also independently verify a claimed Google Partner/Premier Partner status through Google's Partners program.
I'd put these directly into your RFP:
That last question is particularly revealing.
A weak agency talks about CTR, CPC, impressions and Quality Score.
A good one talks about CAC, qualified pipeline, revenue, margin, conversion rates and incrementality.
Get absolute clarity on:
Ad spend + agency fee + technology fees + creative/landing-page costs = total acquisition investment.
Google explicitly recommends understanding the total cost of advertising, including third-party partner fees.
I'd generally avoid compensation structures that create incentives to spend more simply because the agency's fee rises with media spend.
Performance-based compensation can work, but only if the definition of a “performance” is extremely clear and both parties control the variables that affect it.
Don't hire them indefinitely based on a sales presentation.
Define the first 90 days around measurable milestones:
| Area | What I'd expect |
|---|---|
| Measurement | Accurate conversion + revenue tracking |
| Account audit | Prioritized findings with financial impact |
| Waste reduction | Bad queries/placements/targets addressed |
| Campaign strategy | Clear budget allocation by business outcome |
| Testing | Documented hypotheses and experiments |
| Lead quality | CRM feedback incorporated |
| Reporting | Revenue/profit-oriented dashboard |
| Economics | CAC/ROAS/ROI trending toward target |
Importantly, don't demand a magical ROI improvement in 30 days if your sales cycle is long. Demand better measurement and a credible path to profitability.
If an agency says:
“Give us the budget and we'll optimize the account.”
I'd keep interviewing.
A great PPC agency says something closer to:
“First we'll establish what a profitable customer is worth, validate your measurement, identify where your current spend is producing—or destroying—economic value, and then decide where additional advertising makes sense.”
That's the mindset you want.
My hiring formula:
Relevant experience + measurement sophistication + strategic thinking + transparency + aligned incentives > flashy case studies or a Google badge.
When digital ad spend isn’t showing an ROI, the problem is rarely just the ad platform—it’s usually a mix of broken conversion tracking, bloated keyword structures, poor landing page alignment, or misaligned agency incentives.
As a Digital Marketing Manager, your job isn't to find an agency that promises magic; it's to hire a partner whose technical rigor, transparency, and strategic framework can extract profitable growth from your budget.
Step 1: Internal Audit & Goal Setting (Before You Talk to Anyone)
Before interviewing agencies, you need to define your baseline. Agencies cannot optimize toward a vague goal like "more leads" or "better ROI".
Step 2: The Essential Vetting Checklist
When narrowing down your list, use these criteria to separate the top performers from order-takers:
Step 3: High-Value Questions to Ask During Pitches
To gauge their strategic depth, skip the standard introductory fluff and ask these targeted questions:
To help narrow down your agency search:
I can tailor a more specific list of evaluation criteria or give you a template for a Request for Proposal (RFP).
When your digital ad spend isn’t showing an ROI, the problem isn't always the platform—it’s usually strategy, tracking , or execution. As a Digital Marketing Manager, hiring a great PPC agency means shifting from buying "clicks" to buying business outcomes.
Here is a step-by-step framework and checklist to evaluate, interview, and hire a high-performing PPC partner.
Phase 1: Internal Audit & Goal Setting
Before talking to a single agency, lock down your own metrics. An agency that lets you define success purely by clicks or impressions is a red flag.
Phase 2: The Vetting & Interview Checklist
When interviewing agencies, use these targeted questions to separate the order-takers from strategic growth partners:
Phase 3: Red Flags to Walk Away From
To help tailor this approach, could you share:
I can give you a more specific breakdown of what a fair pricing model and realistic KPIs look like for your sector.
If your digital ad spend isn't producing acceptable ROI, the goal isn't simply to replace one PPC agency with another—it's to determine whether the problem is strategy, execution, tracking, creative, landing pages, or market conditions. A strong Digital Marketing Manager should evaluate agencies on their ability to improve the entire acquisition system, not just lower cost-per-click.
A practical hiring framework looks like this:
| Evaluation Area | What to Ask | Strong Answer |
|---|---|---|
| Business understanding | "How would you learn our business?" | They ask about margins, customer lifetime value, sales cycle, and profit—not just keywords. |
| Measurement | "How will you measure success?" | They discuss ROAS, CPA, pipeline, revenue attribution, CRM integration, and conversion tracking. |
| Strategy | "What's your first 90-day plan?" | Audit → quick wins → testing roadmap → scaling plan. |
| Optimization | "How often do you optimize?" | Weekly reviews with continuous testing and documented experiments. |
| Reporting | "What will we receive?" | Custom dashboards, insights, recommendations, and full account transparency. |
| Communication | "Who manages our account?" | Dedicated strategist with regular meetings—not only junior account coordinators. |
Ask each finalist:
The quality of their questions is often more revealing than the quality of their presentation.
The strongest PPC agencies typically:
Be cautious if an agency:
Request:
A simple weighted scorecard can help reduce bias:
| Category | Weight |
|---|---|
| Strategic thinking | 25% |
| Industry experience | 20% |
| Measurement & attribution | 20% |
| Communication & transparency | 15% |
| Technical expertise | 10% |
| Pricing & contract flexibility | 10% |
Have each interviewer score agencies independently before comparing notes.
If ROI has declined recently, don't assume the agency is solely responsible. Before switching partners, verify:
Many "PPC problems" turn out to be measurement or conversion-rate issues rather than media-buying issues. An agency that identifies those broader bottlenecks is generally a stronger long-term partner than one that immediately proposes increasing ad spend.
