Key takeaways
- A percentage-of-spend fee rises automatically as your budget grows. At 10%, $10,000 a month in ads costs you $1,000 in fees, whether performance improves or not.
- Hourly billing pays for time spent, not results delivered. It gives the agency no reason to automate reporting or cut wasted spend.
- A flat monthly retainer costs the same whatever you spend on ads. Meant charges a flat $2,000 a month for performance marketing.
- Your ad accounts should be opened and owned in your business's name, not the agency's, so the data and history stay with you if you change partner.
- Ads work best once the product and site are right. Shordex, a DeFi platform Meant built, ran growth ads after launch. The ads were not standing in for a weak product, and that is the order that tends to work.
If you are working out how to choose a Google Ads partner, start with two questions: how do they charge, and whose name is on the account? Get those two right and most of the overpaying disappears. We are Meant, a studio that builds websites and then runs the Google and Meta ads that send traffic to them. We charge a fixed monthly fee, never a percentage of spend. Below are the three pricing models with the maths, the ownership rules, and what to ask on the first call.
The Three Ways Agencies Charge for Google Ads
Almost every agency bills for Google Ads management in one of three ways. Some mix them. Know which one you are being offered before you compare numbers, because the same headline fee can mean very different things a year later.
Percentage of ad spend
The agency takes a share of whatever you spend on ads each month. Spend more, pay more. The fee is tied to your budget, not to your results.
Hourly billing
The agency logs hours against your account and invoices for them. Setup, optimisation, reporting and calls all go on the clock.
Flat monthly retainer
You pay a fixed fee each month for an agreed scope of work. Your ad budget can double and the fee does not move. This is how we price performance marketing at Meant, and it is the model we would choose if we were the client.
Percentage of Spend: The Maths That Breaks at Scale
Percentage pricing looks reasonable on a small account. The problem shows up as you grow.
What a 10% to 15% fee looks like at different budgets
Here is the fee at 10% and 15% of monthly spend, set against a flat $2,000 retainer.
| Monthly ad spend | 10% fee | 15% fee | Flat retainer |
|---|---|---|---|
| $5,000 | $500 | $750 | $2,000 |
| $10,000 | $1,000 | $1,500 | $2,000 |
| $25,000 | $2,500 | $3,750 | $2,000 |
| $50,000 | $5,000 | $7,500 | $2,000 |
| $100,000 | $10,000 | $15,000 | $2,000 |
To be fair to the model: on a $5,000 budget, a percentage fee is cheaper. Once spend passes about $13,000 to $20,000 a month, the flat fee wins, and the gap keeps widening. At $50,000 a month, a 15% fee comes to $90,000 a year. A flat $2,000 retainer comes to $24,000. The campaigns may be no different.
Why the incentive misaligns as spend grows
A percentage fee pays the agency more when you spend more. It does not pay them more when you earn more. Cutting a wasted keyword lowers their invoice. Recommending a bigger budget raises it.
Most agencies do not act on that incentive. You still should not have to rely on that. When you choose a Google Ads partner, pick a fee structure where the agency's income does not depend on your spend going up.
Hourly Billing: Who the Clock Actually Benefits
Hourly billing feels transparent. You see the hours, you see the rate. The trouble is that good ads management should take fewer hours over time, not more.
What gets billed by the hour
Typically: account audits, campaign builds, keyword research, ad copy, bid changes, reporting, meetings and email. Some of that is skilled work. A lot of it, such as weekly reports and routine checks, is work a well-built system should do with little human time.
Why automation and efficiency work against the agency's income
If an agency automates your reporting, it bills fewer hours. If it builds a cleaner account structure that needs less babysitting, it bills fewer hours. Every efficiency it finds cuts its own income.
Hourly billing also makes your costs hard to predict. A busy month for the agency can mean a bigger invoice for you, with no change in results. The meter measures effort. You are paying for outcomes.
Flat Monthly Retainer: What It Buys and What to Check
A flat retainer separates what you pay the agency from what you pay Google. At Meant, performance marketing runs as a fixed $2,000 monthly retainer. It is month to month, you can stop it, and it is never a percentage of ad spend. Your ad accounts are opened in your name.
A flat fee is only as good as what it covers, wherever you are based. Get that in writing.
What a fixed fee should cover
- Which channels: Google Ads only, or Google and Meta.
- Campaign setup and ongoing management, with what that means in practice.
- Conversion tracking: who sets it up and who checks that it works.
- Reporting: how often, in what format, and against which numbers.
- Landing page changes: included, quoted separately, or not offered.
- Who does the work, by name.
Questions to ask before signing a retainer
- Does the fee change if my ad budget changes?
- What is the notice period, and is there a minimum term?
- Whose name will the ad accounts be opened in?
- Who will I talk to each month, and are they the person doing the work?
- What is not included, and what does it cost if I need it?
If an agency hesitates on any of these, that tells you something. A fixed fee with a vague scope is just hourly billing under a different name.
Why the Ad Account Must Be in Your Name
This is the clause people skip and regret later. Your ad account holds your conversion history, audience data and years of testing. It belongs to the business, not the agency.
What happens if the agency owns the account
Google is clear that a Google Ads client account can only have one owner. If that owner is the agency, leaving becomes their decision as much as yours.
Moving an account between agencies is possible, but it takes care. Google's "Change Who Pays" process exists for exactly when an advertiser changes or leaves agencies. Once a transfer request goes in, the new agency has 7 days to approve or deny it. If no one acts, the request is cancelled and has to be started again. After the transfer takes effect, the account has to be linked to the new manager account within 7 days, or the ads stop running.
If an outgoing agency refuses to cooperate, there is a fallback. You can ask for an export. Google Ads Editor can export the full account to CSV, images included, so you can rebuild it in a new account in your own name. You lose the performance history. That history is what you were paying to build.
The same principle applies on Meta. The business manager and ad accounts should sit under your company. The agency gets access. You keep ownership.
How to check who holds access
In Google Ads, go to Admin, then Access and security. Check that your own company email has Administrative access. Before signing with an agency, and before leaving one, this is the single most important step.
If you are switching partners, plan for an overlap of two to four weeks with both agencies. It prevents downtime and gives the new team time to audit the account before they change anything.
Ads Without a Website That Converts Is Money Burned
The agency fee is usually the smaller cost. The bigger one is ad spend sent to a page that does not convert.
Why traffic without conversion is the usual complaint
Founders tell us that traffic is arriving but customers are not. Ads can be working perfectly and still lose money if the landing page is slow, generic or unclear about what you sell. No bid strategy fixes a page that cannot explain the product in one sentence.
This is where the gap between a dev shop and an ad agency costs real money. The agency spots the problem but cannot change the site. The developer has moved on. At Meant, the same team builds the site and runs the ads, so the fix lands the same week the problem shows up. It also helps to understand how Google Ads and Meta Ads actually differ for ecommerce before you split a budget between them.
How Shordex paired growth ads with the product story after launch
Shordex, a DeFi platform where growth ads carried the launch, is an institutional-grade platform for decentralised hedging. Our job was translation: a digital architecture and brand narrative that turns deep protocol mechanics into a clear story and funnels users towards the dApp. Growth ads carried it after launch.
The order matters. First the product story was made clear, then the ads amplified it. Paid traffic used to cover for a weak product or a confusing site gets expensive fast.
How to Choose a Google Ads Partner: Shortlist in One Call
You can rule most agencies in or out in thirty minutes. Bring these questions.
What to ask about pricing
- Is the fee flat, hourly, or a percentage of spend?
- If my budget doubles next quarter, what happens to your fee?
- Is there a setup fee, a minimum term or a notice period?
- Will you put the price and scope in writing before any work starts?
What to ask about account ownership
- Will the Google Ads and Meta accounts be opened in my company's name?
- Will I hold Administrative access from day one?
- If we part ways, what is your handover process?
What a fixed scope should look like in writing
A proper scope names the channels, the deliverables, the reporting cadence and the person doing the work. It states the monthly fee as a number, separate from ad spend. It lists what is excluded. If the proposal says "ongoing optimisation" and nothing more, ask what that means in hours of attention and in actions taken.

Frequently asked questions
How much should Google Ads management cost per month?
It depends on the pricing model and the scope, so compare the fee alongside what it covers. A flat retainer gives you a predictable number. Meant's performance marketing retainer is $2,000 a month, whatever your ad budget.
Is 10% of ad spend a fair fee for a Google Ads agency?
On a small budget it can be cheaper than a flat fee. As spend grows, the fee grows with it whether or not results improve. At $50,000 a month in ads, 10% is $5,000 a month in fees, which is why percentage pricing tends to stop making sense at scale.
Can I keep my Google Ads account if I switch agencies?
Yes, if it was opened in your name, and Google's "Change Who Pays" process is built for moving between agencies. The new link has to be in place within 7 days of the transfer or the ads stop. If an agency owns the account and will not cooperate, you can request a Google Ads Editor export, but you lose the performance history.
How long does it take to see results from Google Ads?
New ads are usually reviewed within one business day, often in under an hour, but approval is not the same as performance. Smart Bidding needs up to 50 conversion events or 3 conversion cycles to calibrate. A common rule of thumb is 2 to 4 weeks to learn, about 3 months to mature and 4 to 12 months to peak.
Should I run Google Ads or Meta Ads first?
Google Ads catches people already searching for what you sell. Meta Ads puts you in front of people who are not yet looking. Which comes first depends on whether demand for your product already exists. Either way, fix the landing page before you scale the budget.
