A client came to me last year completely demoralized. He'd been with the same Google Ads agency for 14 months. Monthly management fee was $4,500. His ad spend was around $18,000 a month. He had no idea what his cost per acquisition was. His account manager had changed three times. The reports he got every month were full of graphs showing things trending up, but his actual sales hadn't moved.
When I got into his account, I found campaigns that hadn't been touched in months. Negative keyword lists with maybe 40 terms in them despite running broad match keywords. Conversion tracking pointed at a thank you page that hadn't existed since a website redesign eight months prior. The agency had been reporting on form submissions that weren't happening.
That's not bad luck. That's what a lot of agencies actually look like under the hood. I've documented what real results look like in our case studies.
I've managed over $550 million in Google Ads spend. I've worked with more than 400 clients across industries that span everything from luxury brands like Patrón and Godiva to live entertainment with Live Nation. And I can tell you honestly, the number of businesses getting taken advantage of by their Google Ads agencies is genuinely staggering.
This post isn't a hit piece. It's a resource. Because if you know what to look for, you can spot a bad agency before they drain your budget, or audit the one you have right now and hold them to a higher standard.
What You're Actually Paying For (The Math Nobody Wants to Show You)
Let's get into the money first, because this is where a lot of businesses get blindsided.
Most Google Ads agencies in 2026 charge somewhere between $1,500 and $5,000 a month for management on smaller accounts. Sounds manageable. But the bigger agencies often charge a percentage of your total ad spend on top of that, typically 15% to 20%.
Run that math on a real scenario. Say you're putting $20,000 a month into Google Ads.
At 15%, the agency takes $3,000 a month. That's $36,000 a year. For management. Then they add a setup fee somewhere between $500 and $5,000 when you sign. Some charge separately for landing page work, which can run another $1,000 to $5,000 per page. Creative fees on top of that. Exit penalties if you want to leave before your contract is up.
You're looking at a real total cost that can push past $70,000 a year on a $20K monthly ad budget.
The question you have to ask yourself: are you getting $70,000 a year in actual value? Not in "brand awareness" or "impressions" but in customers, revenue, and measurable ROI? Most businesses I talk to aren't. And here's why.
Red Flag #1: They Charge You a Percentage of What You Spend
🚩 Red FlagThis one I genuinely can't understand how it became the industry standard, because it's a straight-up conflict of interest.
When an agency makes more money the more you spend, their incentive isn't to make your campaigns efficient. Their incentive is to get you spending more. Every time they push you to increase your budget without first optimizing what's already running, they're doing it for their wallet, not yours.
I've watched this happen in real time. Agency tells a client they need to increase spend by $10,000 a month to "see results at scale." The campaigns were garbage. Broad match keywords everywhere, no negative keywords, landing pages with 4-second load times. But hey, more spend meant more management fees.
If an agency charges you a percentage of ad spend, that's the first question I'd want answered. What exactly changes in your work when my budget goes from $15,000 to $30,000? Because if the workload doesn't double, why does the fee?
The better model is a flat monthly rate — which is exactly how we structure our pricing. Your incentive and the agency's incentive are now the same thing: get better results within the budget you have.
Red Flag #2: You Don't Have Full Access to Your Own Account
🚩 Red FlagThis should be a dealbreaker. Full stop.
Your Google Ads account, your data, your campaigns. Not theirs. If an agency won't give you admin-level access to the account from day one, there is no legitimate reason for that. The only reason to keep a client out of their own account is because there's something in there they don't want you to see.
The sneakier version of this is agencies that set everything up under their own Manager Client Center, or MCC. You technically have access, but if you leave, they control what gets transferred. According to a 2025 industry survey, about 1 in 5 agency relationships involve some kind of dispute over account ownership when the contract ends. You can lose years of conversion history, audience lists, and campaign data if you're not careful.
You should own the account. Your business email should be the admin. The agency gets manager access and works within your account, not the other way around.
Ask about this before you sign anything. If they hesitate or get weird about it, you have your answer.
Red Flag #3: Their Reports Are Full of Numbers That Don't Mean Anything
🚩 Red FlagI call it the "impressions and vibes" report.
You open the PDF and it's full of bar charts going up and to the right. Impressions up 40%. Click-through rate above industry average. Reach expanded significantly this quarter.
And you sit there nodding because it looks like progress. Meanwhile you're thinking, why aren't my phones ringing more?
Here's what those metrics actually tell you: nothing about whether your business is growing. Impressions just mean people scrolled past your ad. A high CTR is only good if the people clicking are people who actually want what you're selling. Industry average is a meaningless benchmark if your industry average is garbage.
The metrics that matter are cost per click, cost per conversion, conversion rate, return on ad spend, and ultimately cost per new customer. We break down why agencies hide these numbers in another post. WordStream's 2025 data puts the average cost per lead across Google Ads at $70.11 and average conversion rates between 3% and 5% for most industries. If your agency can't tell you where your account stands against those benchmarks, they're not managing your campaigns. They're managing your perception of your campaigns.
Those are very different things.
Red Flag #4: Conversion Tracking Is Broken or Missing Entirely
🚩 Red FlagThis one still gets me every time I see it, because I see it way too often.
I've audited accounts where a business has been spending $15,000, $20,000 a month for six, eight, twelve months. The agency has been sending reports this whole time. And when I dig into the conversion tracking, it's pointing at the wrong page, or it's firing on every page load, or it got broken during a website update and nobody caught it.
The agency had no idea how many leads were actually coming from Google Ads. They were reporting made-up numbers.
Without proper conversion tracking, everything downstream breaks. Google's machine learning can't optimize bidding for conversions it can't see. You can't figure out which campaigns or keywords are actually working. And you definitely can't calculate ROI.
There's also the privacy angle now. GDPR and CCPA have real teeth, and agencies that haven't implemented Enhanced Conversions or first-party data strategies are leaving money on the table and potentially creating compliance headaches.
A good Google Ads agency sets up conversion tracking before the first dollar gets spent. Phone calls, form submissions, purchases, email signups. All of it. And they audit it regularly to make sure it's still working.
Red Flag #5: Your Campaigns Are Running on Mostly Broad Match Keywords
🚩 Red FlagBroad match isn't evil. But it requires real management, and most agencies don't put in that work.
When you use broad match keywords without aggressive negative keyword management, Google decides what searches are "close enough" to your keyword. And Google's definition of close enough is famously loose. I've seen campaigns where someone advertising for "commercial roofing contractors" was getting clicks from people searching "diy roof repair" and "roof cost estimator." Not the same customer. Not even close.
Every one of those clicks costs money. Real money from your real budget.
The fix isn't complicated. Use a smart mix of phrase match and exact match keywords. Build a negative keyword list that actually covers your bases, not just 15 obvious terms but hundreds. Check your search terms report every single week and add new negatives constantly.
Most agencies don't do this because it's unglamorous work that takes time. It's a lot easier to set up broad match campaigns, let them run, and spend your 40-minute weekly "account review" looking at the dashboard.
Red Flag #6: Cookie-Cutter Campaigns With No Real Strategy
🚩 Red FlagYou can always tell when an agency is running templates.
The campaign structures look the same across clients. The ad copy follows the same formula. The bidding strategy never changes. You get the sense that your "dedicated account manager" set up your campaigns on a Tuesday afternoon in two hours and hasn't really thought about your business since.
I get it from a business model standpoint. If you're managing 60 clients and charging each one $2,000 a month, you can't give everyone real strategic attention. The math doesn't work. So you systemize everything, use templates, and hope nobody looks too closely.
But your business isn't a template. Your customers, your margins, your competitive situation, your seasonal patterns, what converts and what doesn't. That's all specific to you. A Google Ads strategy that works for a SaaS company doesn't work for an HVAC company. Anyone telling you otherwise is saving themselves time at your expense.
A real agency asks a lot of questions before building anything. They want to know your best customers, your worst customers, what makes you different from competitors, what your margins look like, what success actually means for your business. If they skipped all that and went straight to pitching a package, that's your answer.
Red Flag #7: Long Contracts With Painful Exit Clauses
🚩 Red FlagIf an agency needs a 12-month contract with early termination fees to keep your business, they know they can't keep it on the results alone.
That's just the truth of it.
Good agencies work month-to-month or with short notice periods because they're confident that the results they deliver will make you want to stay. Locking you into a year-long commitment is a hedge against their own underperformance.
Read the contract carefully before you sign. Look for automatic renewal clauses, minimum spend commitments, and data ownership language specifically. Some agencies bury language saying that the campaigns, ad copy, and account structure they created are their intellectual property. Which means if you leave, you're starting from scratch.
Red Flag #8: They Promise Specific Results Before They Know Anything About Your Business
🚩 Red Flag"We guarantee 300% ROI in 90 days."
No. They don't. They can't. And any agency saying that is either lying to close the deal or planning to do things to your account that might produce short-term numbers but will hurt you long-term.
Google Ads performance depends on your product, your pricing, your website, your competition, the time of year, the economic climate, and about a hundred other variables the agency doesn't control. A good agency sets realistic expectations based on industry benchmarks and a proper discovery process.
The honest answer to "how long until we see results" is usually two to four weeks to get enough data for real optimization decisions, followed by a few months of steady improvement as machine learning algorithms learn your account. Anyone promising instant results or guaranteed outcomes is telling you what you want to hear.
Red Flag #9: You Can't Get a Straight Answer Out of Anyone
🚩 Red FlagThis one's harder to quantify but it matters a lot.
When you send an email, how long does it take to hear back? When something breaks or performance drops, do they reach out to you proactively or wait until you notice? When you ask a direct question about what they're doing and why, do you get a real answer or a wall of jargon?
A lot of agencies have a sales team that's incredible and an account management team that's overwhelmed and undertrained. You get treated like a priority during the pitch and like an afterthought once the contract is signed.
Some agencies assign "account managers" who are genuinely managing 50 or 60 clients simultaneously. They don't have time to actually understand your business, let alone think strategically about your campaigns. You're getting reactive management at best, meaning they fix things after they break rather than preventing problems in the first place.
Regular check-ins, proactive communication about performance changes, quick turnaround on questions. These aren't perks. They're the job.
What a Good Google Ads Agency Actually Looks Like
I want to be clear about something. There are excellent agencies out there. Not many, but they exist.
The ones that are actually worth hiring share a few things in common.
They're upfront about pricing and what's included. No hidden fees, no surprise charges, no percentage-based model that rewards them for spending more of your money.
They give you full access to everything. Your account, your data, your reports. You can look at anything you want, any time you want.
They report on business outcomes, not just ad metrics. Leads, cost per lead, revenue from ads, ROI. Not impressions and click-through rate graphs.
They set up conversion tracking correctly from the start and check it regularly because they know that everything else depends on that data being accurate.
They tell you what's not working and why. A good agency doesn't hide bad news in their reports. They show you the ugly numbers, explain what happened, and tell you what they're doing about it.
They earn your business every month and act like it.
The Bottom Line
I built Market Correct because I was tired of watching businesses get taken advantage of by agencies that are better at selling their services than actually delivering results. I've managed $550 million in ad spend. I know what these campaigns should look like when someone's actually paying attention.
You deserve transparency. You deserve to know where every dollar is going and what it's producing. You deserve an agency that works for you, not for the percentage of your budget they can capture.
