Ask five agencies what Google Ads management costs and you will get five different structures, which is most of why the question is hard to answer. The fee itself is only half of it. The other half is what the fee is attached to, and whether your ad spend is passing through someone else’s hands on the way to Google.
How much does Google Ads management cost?
There are four common models: a flat monthly fee, a percentage of ad spend, an hourly rate, and a hybrid of flat fee plus percentage. Across agencies, WordStream puts the average management fee at around 10% to 20% of ad spend. Performance-based pricing exists but is rare.
The split between models is less lopsided than you might expect. In WordStream’s survey, roughly a third of agencies used a flat rate and roughly a third used the flat-fee-plus-percentage hybrid. About 15% billed hourly, and 13% charged a straight percentage of spend.
We are not going to quote dollar ranges for other agencies, because the honest ones vary enormously by scope and the published numbers are mostly marketing. What we can say is what our own pricing is, further down, and what the fee should buy regardless of who charges it.
One thing to be clear about before comparing quotes: the management fee and the ad spend are two separate costs. A $1,500 quote means nothing until you know whether that is the fee, the spend, or both bundled together.
What does a management fee actually include?
At minimum: account structure, keyword and negative keyword work, ad copy and testing, bid strategy management, conversion tracking, and reporting that ties spend to leads. Anything less is account babysitting. Anything billed as management that produces only a monthly PDF is not management.
Here is the more useful way to read a proposal. Ask what happens in a normal week. A well-run account has a search terms report reviewed regularly, negatives added, budget shifted between campaigns that are working and campaigns that are not, and ad variants tested against each other. None of that is exotic. It just requires someone to be doing it.
Then ask what happens outside the ad account. Conversion tracking is the single most common thing we find broken when we take over an account, and an account without working tracking is being optimized against the wrong signal. Call tracking, form tracking, and offline conversion imports where the sale happens on the phone are all part of the job even though none of them live inside Google Ads.
Finally, ask about the landing page. Google will happily charge you full price to send traffic to a page that cannot convert. If the fee does not include either landing page work or an honest conversation about the page, half the money is being spent upstream of the problem.
Should ad spend be marked up?
No. Ad spend should be billed directly by Google to your own card, in an account you own, with the management fee invoiced separately. That is our published position and we do not make exceptions to it. A marked-up spend line is impossible for you to audit and gives your agency a reason to prefer bigger budgets over better ones.
The mechanics matter here. Google Ads charges you per click, and the actual cost per click is usually lower than your maximum bid because the auction only charges enough to hold your position (Google Ads Help). Those figures are visible to you in your own account, down to the individual keyword. If your spend runs through an agency’s account instead, that visibility disappears and you are trusting a summary.
Ownership is the other half of the same point. If you leave, an account in your name goes with you, along with its conversion history and machine learning. An account in the agency’s name does not, and rebuilding that history costs real money. Ask the ownership question during the sales conversation, not after.
Percentage of spend vs flat fee: which is fairer for a small business?
At small budgets, a flat fee is usually fairer. Percentage pricing ties your fee to your spend rather than to the work, so the fee climbs when you scale even if the account got simpler. It also breaks in the other direction: 10% of a small budget rarely funds enough hours to manage anything properly.
Percentage pricing has a defensible logic at scale. Bigger budgets usually mean more campaigns, more geographies, more product lines, and genuinely more work, so the fee tracking spend is roughly reasonable. The trouble is that the correlation is loose. A $20,000 single-service local account can be simpler to run than a $4,000 account with eleven service lines and four locations.
There is also an incentive problem that nobody likes to say out loud. If the fee is a percentage of spend, every recommendation to spend more is also a recommendation to pay the agency more. That does not make the recommendation wrong, but it does mean you should ask for the reasoning rather than the conclusion.
The hybrid model splits the difference: a base fee that funds the actual work, plus a smaller percentage that scales with the account. It is the most common structure in WordStream’s numbers for a reason.
What should you expect in the first 90 days?
Month one is setup, tracking, and data collection. Month two is pruning — negatives, wasted spend, restructuring what the first month exposed. Month three is where a trend in cost per lead should start to be visible. Faster results happen, but they are usually a sign that the previous setup was badly broken rather than that the new one is brilliant.
What you should expect immediately is transparency. Access to your own account in week one. Conversion tracking verified and tested, not assumed. A written statement of what is being measured as a conversion, because “form submission” and “qualified lead” are very different things and half the arguments about ad performance come from confusing them.
What you should not expect is a promise of a specific cost per lead in month one. Anyone confident enough to give you a number before seeing your search terms report is guessing, and the guess is a sales tactic.
How do you know if you’re overpaying?
Three tests. Can you log into the Google Ads account yourself and see the real spend? Does the fee correspond to identifiable work rather than a report? And is the fee sized against the account’s complexity rather than a percentage plucked from the spend? Fail any one of those and the fee is buying access, not management.
A fourth, softer test: what happens when the numbers are bad. A good manager tells you before you notice, explains the cause, and says what they are changing. If bad months arrive as silence and good months arrive as a slide deck, you are paying for account management and receiving account narration.
And be suspicious of the fee that never changes as the account changes. Accounts get simpler as well as more complex. If the account has consolidated from six campaigns to two and the fee never moved, ask why.
What Site Altitude charges
Our ads management starts at $599/mo, and full programs start at $1,000/mo. Ad spend is separate, goes straight to Google, and is never marked up. You own the Google Ads account, so you keep it and its history if you ever leave. All of that is published on our pricing page rather than saved for the sales call.
The reason we publish it is the same reason we do not mark up spend. Published pricing means you can rule us out in thirty seconds if the number is wrong for you, which is better for both of us than a discovery call that exists to find out what you can afford. What the fee covers on the ads side is set out on our Google Ads page.
If you are comparing quotes right now, the most useful thing you can do is normalize them. Strip out the ad spend, confirm who owns the account, and ask each one what work happens in a typical week. Most of the price difference you are looking at will turn out to be a scope difference, and a few of the cheap ones will turn out not to include the work at all.
