The 4 Pricing Models, and What Each One Incentivizes
Every Google Ads management quote you receive is a variation of 4 models. None of them is dishonest and none of them is neutral: each one pays the agency for a different behavior, and over 12 months that behavior shapes your account far more than any single optimization. We have run agency accounts since 2008, and the pattern holds across every market and language we work in.
1. Percentage of Ad Spend
The classic model: the fee is a share of your monthly media budget, commonly reported between 10% and 20%, often sliding downward as spend scales. It is simple to budget and scales with account size. The incentive problem is structural: the agency earns more when you spend more, whether or not the extra spend produces leads. A percentage-of-spend agency that recommends cutting your budget is acting against its own invoice, and few do it twice.
2. Flat Monthly Retainer
A fixed fee for a defined scope, commonly reported between $1,500 and $10,000 or more per month for mid-market B2B accounts depending on markets, languages and campaign volume. Predictable for both sides, and the fee is decoupled from spend, so advice about budgets stays clean. The risk sits in scope: a retainer with a vague deliverables list quietly decays into a monitoring service. The fix is contractual, not motivational, which is what the 10 questions below are for.
3. Hourly
Commonly reported between $100 and $300 per hour depending on seniority and market. Hourly pricing fits bounded work: audits, migrations, tracking rebuilds, a second opinion before a big budget decision. It fits continuous management poorly, because the agency is paid for time spent rather than outcomes reached, and because you cannot budget a number that depends on how messy your account turns out to be.
4. Performance-Based
A price per lead, or a share of attributed revenue, sometimes hybridized with a small base fee. It sounds like perfect alignment and occasionally is. The structural problem: the agency is paid for lead volume, and the cheapest leads to generate are rarely the ones your sales team accepts. Pure performance deals also push agencies toward short-term channels and away from the slow compounding work, brand protection, negatives discipline and tracking accuracy, that makes an account durable.
The Models Side by Side
| Model | Commonly reported range | Pays the agency for | Best fit | Watch out for |
|---|---|---|---|---|
| % of spend | 10% to 20% of monthly budget | Growing your spend | Large accounts with stable, proven economics | Budget advice that always points up |
| Flat retainer | $1,500 to $10,000+ per month | Delivering a defined scope | Mid-market B2B, multi-market accounts | Vague scope decaying into monitoring |
| Hourly | $100 to $300 per hour | Time spent | Audits, rebuilds, projects | Open-ended hours on continuous work |
| Performance | Per lead or % of revenue, varies widely | Lead volume | High-volume, fast-feedback offers | Cheap leads your sales team rejects |
All ranges are commonly reported market figures, not quotes; your market, languages and account complexity move them. The point of the table is not the numbers, it is the third column. Read any proposal by asking what behavior the fee structure pays for.
What a Management Fee Should Include
Whatever the model, the fee buys a scope, and the scope is where good and bad engagements diverge. A serious Google Ads management fee covers, at minimum:
- Strategy first. Keyword and audience strategy tied to your pipeline targets, revisited quarterly, not a launch plan from month one reheated forever.
- Search term reviews on a stated cadence. Weekly or biweekly, with documented actions and a shared negative list that grows.
- Ad copy and testing. Written natively for each market you sell in, with a testing calendar you can see. Machine-translated ads are a fee discount you did not agree to.
- Conversion tracking and consent ownership. Someone must own the bridge from click to CRM, including consent configuration. If nobody owns it, your bidding runs on fiction.
- Landing page recommendations. The agency does not need to build pages, but a manager who never mentions your landing pages is optimizing half the system.
- Reporting on lead quality, not clicks. Cost per qualified lead against target, in a report a CFO could read. Our view of what that reporting looks like is on the Google Ads management page.
- Your ownership of the account. The Google Ads account, its history and its data belong to you. An agency that holds your account hostage has priced in your exit.
The 10 Questions to Ask Any Agency, Including Us
The checklist we would want a prospect to run on us. The gated PDF version formats these as a one-page scoring sheet, but the questions themselves are right here:
- Who owns the Google Ads account and its data if we part ways, and is that in the contract?
- What exactly happens in the account in a normal week, and what would I see in the change history?
- On what cadence do you review search terms, and can I see the negative list you maintain?
- How many hours of senior specialist time does my fee buy, versus junior or offshore execution?
- How do you define a conversion in my account, and how does an unqualified lead get excluded?
- What does your reporting show about cost per qualified lead, and can I see an anonymized sample?
- What is the contract length, the notice period, and what do I take with me when I leave?
- Who writes the ad copy for each of my markets, and in what language do they think?
- How will you connect campaign data to my CRM so we optimize on accepted leads, not form fills?
- Describe an account you told to spend less. What happened to your fee when they did?
Question 10 does the most work. Every model except the flat retainer makes it financially uncomfortable, and the answer tells you how the agency behaves when your interest and its invoice point in different directions.
How to Normalize Quotes: Price per Accepted Lead
Three proposals with three different models cannot be compared on fee. Normalize them on one number: the total monthly cost, fee plus ad spend, divided by the number of leads your sales team would accept.
Ask each agency to estimate accepted-lead volume at your intended budget, in writing. Then compute total cost per accepted lead for each proposal. A $4,000 retainer that produces 40 accepted leads on $10,000 of spend costs $350 per accepted lead; a $2,000 fee that produces 15 costs $800. The cheap proposal is the expensive one, and you cannot see that on the fee line. Two useful side effects: agencies that refuse to estimate volume have told you something, and the estimates become the first thing you hold the winner to. This is the same lens we apply across every channel in a B2B lead generation program, and it is the number that should govern your whole PPC budget, the agency line included.
Where We Sit
For transparency: we work on flat monthly retainers scoped to your markets, languages and campaign volume, with account ownership always yours and no long lock-ins. We will tell you in one scoping call whether we are a fit and what the retainer would be, and if we are not the right size or shape for your account, we say so on that call.
Agency Pricing, Answered
How much does Google Ads management cost?
Commonly reported figures: 10% to 20% of ad spend under percentage models, $1,500 to $10,000 or more per month for mid-market flat retainers, and $100 to $300 per hour for project work. Your markets, languages and account complexity move every one of those numbers, which is why quotes should be normalized on total cost per accepted lead rather than compared on fee.
Is percentage-of-spend pricing bad?
Not inherently. It is simple and it scales, and for large accounts with proven economics it can be fair. Its structural weakness is that the agency earns more when you spend more, so budget advice carries a conflict of interest. If you choose it, put question 10 from the checklist to the agency and listen carefully.
Should I choose performance-based pricing?
Only if lead volume, not lead quality, is genuinely your constraint, and your feedback loop is fast enough to catch quality problems within weeks. For most B2B companies with considered sales cycles, performance pricing optimizes for the wrong number. Hybrid structures with a base fee plus a quality-gated bonus age better.
What ad budget do I need before hiring an agency?
There is no universal floor, but many agencies set minimums because management effort does not shrink with budget. A practical test: if the management fee exceeds roughly a third of your media spend, your money likely works harder going into spend with lighter-touch management until volume justifies the fee.
What is the single biggest red flag in a proposal?
An agency that cannot tell you, specifically, what happens in your account in a normal week. Pricing model debates matter less than whether the fee buys defined, inspectable work. The change history in your account does not lie, and you should have access to it from day one.
