How to choose a Google Ads agency: fees, questions to ask and red flags

Every Google Ads agency promises lower costs and more leads. Here's how to tell which ones will actually run your account well, before you've spent a quarter's budget finding out.

Most businesses that hire a Google Ads agency are not buying clicks. They are buying judgment: which searches are worth paying for, how much a customer is worth, and when to stop spending on something that isn't working. The problem is that every agency sells the same promise, and the difference between a good one and an expensive one only shows up three months and a lot of budget later.

This guide is for founders and marketing heads who want to tell them apart before signing. It covers what a Google PPC agency should actually do in your account, how fees work, the questions that expose weak operators, and the red flags worth walking away from.

What a Google Ads agency actually does

Strip away the pitch deck and the job has five parts. If an agency can't explain how it handles each one for your business, it is selling account maintenance, not growth.

• Measurement first. Conversion tracking that records the actions that make you money (a qualified lead, a purchase, a booked call, an app signup), with values attached where possible. Bidding is only as smart as the conversions you feed it.
• Account structure. Campaigns split by what actually behaves differently: brand vs non-brand, product lines, margins, geographies. Not one campaign per keyword idea.
• Bidding and budget allocation. Choosing between maximize conversions, target CPA and target ROAS, and moving budget weekly toward the campaigns that hit target.
• Search terms and negatives. With broad match and AI Max for Search campaigns expanding which queries trigger your ads, reviewing search terms and adding negatives is still one of the highest-value hours of the week.
• Creative and landing pages. Responsive search ad assets, Performance Max asset groups, and honest feedback on the page the click lands on. A landing page problem looks like a bidding problem in the reports.

What a Google Ads agency shouldn't do: report "impressions up 40%" as a win, change bid strategies every few days, or hide the search terms report from you.

How a good Google PPC agency runs your account: the first 90 days

The first quarter tells you most of what you need to know about an agency. Here is what a competent rollout looks like.

1. Week 1: audit and tracking. Review the existing account, conversion actions, Google Analytics links and offline conversion imports. Fix tracking before touching bids. You should get a written audit, not a slide of "opportunities".
2. Weeks 2–3: rebuild or restructure. Brand and non-brand separated, high-intent keywords in their own campaigns, negatives lists in place, Performance Max scoped so it doesn't simply absorb your brand traffic.
3. Weeks 3–6: learning and testing. Smart bidding needs conversion volume to stabilize, so the agency should hold strategies steady and test one thing at a time: ad assets, landing pages or audiences.
4. Weeks 6–10: reallocate. Move budget from campaigns above target cost per acquisition to those below it. Cut what isn't working, even if it was the agency's idea.
5. Weeks 10–13: scale or rethink. If unit economics work, raise budgets in steps. If they don't, the conversation should be about offer, pricing, landing page or targeting, not "give it more time".

Running Google Ads for an app instead of a website? The mechanics are different. App campaigns optimize toward in-app events through your attribution setup; see our guide to how Google App Campaigns work.

Google Ads agency fees: the common pricing models

Ad spend and agency fees should always be separate lines. You pay Google directly for media; you pay the agency for management. The fee models below are the ones you'll see most often. Exact amounts vary widely by country, account complexity and agency size, so treat them as structures to compare, not price lists.

Whatever the model, ask what the fee covers each month in hours or deliverables, how much notice either side must give, and whether there's a setup fee on top. For app-focused budgets, our breakdown of performance marketing KPIs and fees goes deeper.

Questions to ask before you hire a Google Ads agency

The best Google Ads agency for you is the one that gives specific answers to these. Vague answers are your answer.

• Who will actually work on my account, and how many other accounts do they handle? The senior person on the sales call is often not the person in the account.
• Which conversion actions will you optimize toward, and why? A good answer ties directly to revenue, not form fills of any quality.
• What will you change in the first 30 days? Expect a prioritized list after they've looked at the account, not before.
• How do you handle Performance Max and brand traffic? They should have a view on brand exclusions and on reading channel and search term insights.
• What does a weekly or monthly report contain? Cost per acquisition or ROAS by campaign, what changed, what they'll do next.
• Can I see a redacted example of an account you manage at a similar spend level? Screens of real account structure beat logo walls.
• What happens if we part ways? The account, its history and all assets must stay with you.

Red flags when comparing Google advertising agencies

• The agency wants to run ads in its own account. You lose the history, the learnings and sometimes the account itself when you leave.
• Promised results before they have seen your data. Nobody can honestly promise a cost per lead without knowing your market, offer and conversion rate.
• Reports built around impressions, clicks and CTR. Those are diagnostics. The scoreboard is cost per acquisition, revenue and margin.
• No access to search terms or change history. If they won't let you look, assume there's a reason.
• Long lock-in contracts with no performance exit. A reasonable notice period is normal. Twelve months with no way out is not.
• Constant restructuring. Rebuilding the account every month resets learning and makes it impossible to see what worked.

What the Google Partner badge does and doesn't tell you

Many agencies lead with the Google Partner badge. It's a useful baseline, not a quality guarantee. According to Google's own requirements, Partner status depends on a manager account keeping an optimization score of at least 70%, at least $10,000 USD in ad spend across managed accounts over 90 days, and at least half of account strategists holding Google Ads certifications.

That tells you the agency spends real money and is engaged with Google's tooling. It doesn't tell you whether they're good at your kind of business. Optimization score in particular rewards adopting Google's recommendations, and not every recommendation is right for every account. Ask how they decide which recommendations to accept and which to dismiss.

Who should own the account, and what access to give

Create the Google Ads account under your company, with your billing details, and invite the agency. Google Ads has five access levels: Email-only, Billing, Read-only, Standard and Admin. Admin users can add and remove other users, change payment settings and unlink manager accounts, so keep at least one Admin seat on your side permanently.

Agencies normally manage your account by linking it to their manager account (MCC). That's fine, as long as the link can be removed by you and the account itself stays yours. The same rule applies to Google Analytics, Google Tag Manager and Merchant Center.

Specialist Google PPC agency or full-service shop?

You'll still see some firms describe themselves as Google AdWords agencies. Google renamed AdWords to Google Ads in 2018, so the label itself doesn't matter. What matters is focus.

Frequently asked questions

How much does a Google Ads agency charge?

Most agencies charge a flat monthly retainer, a percentage of ad spend, or a hybrid of the two, and some add a one-off setup fee. Amounts vary widely by country, account size and complexity. Whatever the model, the fee should be separate from your ad spend, which you pay directly to Google, and the agency should state in writing what the fee covers each month.

Is it worth hiring a Google Ads agency?

It is usually worth it when you spend enough that small improvements in cost per acquisition pay for the fee, and you don't have an experienced in-house PPC specialist. For very small budgets, a one-off audit and setup followed by in-house management can be better value than a monthly retainer.

What is the difference between a Google Ads agency and a PPC agency?

A PPC agency manages pay-per-click advertising across several platforms, which can include Google Ads, Microsoft Advertising, Meta, LinkedIn and Amazon. A Google Ads agency focuses on Google's platform: Search, Performance Max, Shopping, YouTube, Display and App campaigns. In practice many agencies use the terms interchangeably, so ask which platforms they actively manage today.

Does a Google Partner badge mean an agency is good?

Not on its own. Google Partner status requires a minimum optimization score, a minimum level of ad spend across managed accounts, and certified staff. That shows the agency is active and engaged with Google's tools, but it doesn't prove they understand your market or that they will make the right calls for your account.

Who should own the Google Ads account when using an agency?

You should. Create the account under your company with your own billing, then invite the agency or accept a link to their manager account. Keep at least one Admin user on your side so you can remove access, change payment settings and keep your campaign history if you change agencies.

How long before a Google Ads agency shows results?

Tracking and structural fixes can improve efficiency within the first few weeks, but smart bidding needs time and conversion volume to settle. Most accounts need roughly one to three months before you can judge whether cost per acquisition is moving in the right direction. Be wary of agencies that promise immediate results or ask for six months before any review.
