If your Google Ads agency is underperforming, the signs are almost always hiding in plain sight. A bad Google Ads agency wastes your budget through neglect, misaligned incentives, and a lack of proactive optimization. The problem is that most businesses do not know what to look for, so underperformance goes undetected for months or even years. This guide covers 10 specific warning signs that your Google Ads agency is wasting your budget, explains why each one happens, and tells you exactly what to do about it.
A Google Ads agency not performing is one of the most expensive problems a growth team can have, because the damage is not just the management fee. It is the wasted ad spend, the missed revenue, and the opportunity cost of campaigns that should have been working harder. If you are searching "should I fire my PPC agency" or "is my Google Ads agency doing a good job," this article will give you a clear framework to answer that question.
The Real Question: Is Your Google Ads Agency Actually Working?
Most businesses paying for Google Ads management cannot definitively say whether their agency is doing a good job. They see reports, hear jargon on calls, and watch spend go out the door. But the connection between what the agency does and what the business gets back remains frustratingly opaque.
Why Most Businesses Can't Answer This Question
The core issue is information asymmetry. Your agency knows Google Ads. You know your business. But the overlap between those two areas of expertise is often thin enough that agencies can control the narrative. They pick the metrics that look favorable. They frame results in the context that suits them. And unless you have deep PPC knowledge yourself, you are trusting their interpretation entirely.
This is not always malicious. Many agencies genuinely believe they are doing good work. But "good" is relative. An agency that was performing well two years ago might be coasting on outdated structures today. Google Ads changes rapidly, and what worked in 2024 often underperforms in 2026. If your agency is not actively evolving your account, they are falling behind, and your budget is paying for it.
The Conflict Of Interest Built Into Agency Relationships
Here is the structural problem that most businesses overlook: traditional agencies are incentivized to maintain the status quo, not to maximize your results. The percentage-of-spend pricing model rewards agencies for keeping budgets high. The retainer model rewards them for keeping you as a client, regardless of performance. And the hourly model rewards them for taking longer, not for being more efficient.
None of these models align the agency's financial interest with yours. That misalignment does not mean every agency acts in bad faith. But it does mean that when performance slips, the agency's incentive is to explain it away rather than fix it urgently. This is one of the reasons why businesses increasingly look for alternatives to the traditional agency model, and why services like groas, which pair AI agents running campaigns 24/7 with a dedicated human account manager, have gained traction as a replacement that eliminates these structural conflicts.
10 Signs Your Google Ads Agency Is Underperforming
1. They Can't Explain What Changed Or Why
If you ask your agency "what did you do this month and why?" and get vague answers, that is a red flag. A competent agency should be able to articulate specific actions taken, the reasoning behind them, and the expected impact. Phrases like "we optimized your campaigns" or "we made some bid adjustments" without specifics usually mean very little was done.
Why this happens: many agencies manage too many accounts per person. When an account manager is juggling 30 to 50 accounts, the honest answer to "what changed?" is often "not much." The work becomes reactive rather than proactive.
2. Your Reports Look Great But Revenue Hasn't Moved
Vanity metrics are the easiest way for an underperforming agency to buy time. If your reports highlight impressions, click-through rate, and Quality Score improvements but your actual revenue, pipeline, or qualified leads have not improved, there is a disconnect. The metrics that matter are the ones tied to business outcomes, not platform activity.
Why this happens: agencies control which metrics they report on. If CPA is rising or conversion volume is dropping, you will often see the reporting emphasis shift to engagement metrics that tell a more flattering story.
3. They Haven't Touched Your Negative Keywords In Months
Negative keyword management is one of the most important ongoing tasks in Google Ads. If your agency is not regularly reviewing search terms and adding negatives, you are almost certainly paying for irrelevant clicks. This is one of the simplest things to check and one of the most commonly neglected.
Why this happens: negative keyword work is tedious and unglamorous. It does not look impressive on a report. But it directly impacts your cost per acquisition and budget efficiency. An agency that neglects it is prioritizing their own convenience over your results.
4. Account Access Is Restricted Or Shared Reluctantly
You should have full admin or owner access to your Google Ads account at all times. If your agency resists giving you access, insists on running everything through their MCC without transparency, or makes you feel uncomfortable for asking, that is a significant warning sign. Your account is your asset. You are paying for it.
Why this happens: some agencies restrict access because they do not want you to see what is (or is not) happening inside the account. Others do it because they worry you will leave and take the account with you. Neither reason is acceptable.
5. Your CPA Has Crept Up While They Claim 'Optimization'
If your cost per acquisition has been gradually increasing over a period of months and your agency describes the account as "optimized," something is wrong. True optimization should hold or improve CPA over time, not let it drift upward. Auction dynamics do change, but a good manager adapts to those changes rather than accepting them as inevitable.
Why this happens: CPA creep is common in accounts that are not being actively managed. Bids go stale, ad fatigue sets in, competitors adjust their strategies, and an account that is on autopilot slowly degrades. This is exactly the kind of decay that continuous, around-the-clock management prevents. It is why groas uses AI agents that monitor and adjust campaigns 24/7, with a dedicated human account manager catching the strategic shifts that require human judgment.
6. They're Still Running The Same Ads From Six Months Ago
Ad creative should be tested and refreshed regularly. If your agency has not introduced new ad variations, tested different messaging angles, or updated responsive search ad assets in six months, your campaigns are almost certainly suffering from ad fatigue. Stale creative leads to declining click-through rates, which increases your cost per click and degrades overall performance.
Why this happens: writing new ad copy, developing test hypotheses, and analyzing results takes real effort. Agencies that are stretched thin tend to deprioritize creative testing because the short-term impact is less visible than, say, a budget reallocation.
7. Broad Match Is Eating Your Budget With No Monitoring
Broad match keywords can be powerful when combined with Smart Bidding and tight negative keyword lists. But when an agency deploys broad match without monitoring the search terms it triggers, your budget can hemorrhage on irrelevant queries. Check your search terms report. If you see queries that have nothing to do with your business, and they have been running for weeks, your agency is not watching.
Why this happens: broad match is the default match type Google recommends, and it can simplify campaign structure. But it requires diligent ongoing oversight. Agencies that set and forget broad match keywords are not managing your account; they are hoping Google's AI does the work for them.
8. They're Billing A Percentage Of Spend (Incentivized To Waste It)
The percentage-of-spend model is the most common agency pricing structure, and it is fundamentally misaligned with your interests. If your agency earns 15% to 20% of your ad spend, they make more money when you spend more, regardless of whether that additional spend is profitable. This does not mean every agency on this model is overspending your budget. But the incentive structure makes it possible, and you should be aware of it.

9. The 'Strategy Call' Is Actually A Report Readout
Your bi-weekly or monthly call with your agency should be a strategic conversation. If instead it consists of someone reading numbers off a dashboard and asking if you have questions, that is not strategy. A real strategy call involves forward-looking plans, test proposals, competitive observations, and discussions about business context that should influence campaign decisions.
Why this happens: agencies often assign junior account managers to handle client calls while senior strategists are busy with new business pitches. The person on your call may not have the experience or authority to make strategic recommendations.
10. You Feel Like You Need To Chase Them For Answers
If getting a response from your agency feels like pulling teeth, the relationship is already broken. Slow communication is not just frustrating; it is a symptom of deprioritization. When an agency is not responsive, it usually means your account is not receiving much active attention either.
Why this happens: agencies have limited human bandwidth, and their attention goes to squeaky wheels, new clients, and big spenders. If your account is mid-tier in their portfolio, you may be getting mid-tier attention.
How To Audit Your Own Account Before Firing Your Agency
Before making any changes, gather evidence. A quick self-audit will tell you whether your concerns are justified or whether there are factors you might be missing.
The 30-Minute Account Health Check Anyone Can Do
Log into your Google Ads account and check these things. Change history: look at the last 90 days. How many changes were made, and by whom? If the change history is sparse, your account is not being actively managed. Recommendations tab: are there dozens of unaddressed recommendations? While not every Google recommendation should be applied, a completely ignored recommendations tab suggests nobody is looking. Campaign structure: do your campaigns have a logical structure, or does it look like things have been bolted on over time without a clear plan?
Red Flags In Search Terms Reports
Pull the search terms report for the last 30 days. Look for queries that are clearly irrelevant to your business. Calculate what percentage of your spend went to these irrelevant terms. Even 10% to 15% irrelevant spend adds up to serious waste over a quarter. If you find significant irrelevant traffic, your agency has not been managing negative keywords.
How To Calculate What You're Actually Paying Per Lead
Take your total Google Ads spend for the last 90 days. Add your agency management fee. Divide by the number of qualified leads or customers acquired. This is your true cost per acquisition, and it is often significantly higher than the CPA your agency reports because they typically exclude their own fee from the calculation. If this number is higher than you expected, that is the real cost of underperformance.
What To Do When You Confirm The Problem
Transitioning Away From An Agency Without Losing Campaign History
First, make sure you own your Google Ads account. If the account was created under your agency's MCC and you do not have direct ownership, you need to resolve that before making any move. Request admin access immediately. Your campaign history, conversion data, and Quality Score history all live in the account, and losing them means starting from a weaker position.
Once you have confirmed ownership, document the current account state. Take screenshots of campaign structures, note the current bid strategies, and export your keyword lists, negative keyword lists, and audience segments. This documentation ensures that whoever takes over can understand what was in place and make informed decisions about what to keep and what to change.

What Autonomous Management Looks Like As A Replacement
The alternative to a traditional agency is not necessarily another agency with the same structural problems. Autonomous Google Ads management, where AI handles the continuous daily optimization and a human strategist handles the thinking, eliminates most of the failure modes described in this article.
With a service like groas, your account gets a dedicated human account manager from day one. That manager audits your account, builds a custom roadmap within 24 hours, and implements the full plan. From there, AI agents manage your campaigns around the clock, making the kind of continuous adjustments that no human team can sustain. Your account manager oversees everything, runs bi-weekly strategy calls, and is available via private Slack channel or email whenever you need them.
This model directly addresses the problems listed above. Negative keywords get managed continuously, not when someone remembers. Ad creative gets tested based on data, not on a quarterly schedule. CPA drift gets caught and corrected in real time, not at the next monthly review. And communication is always on, because the service is built around availability rather than billable hours.
Why groas Exists: The Alternative To The Agency Model
groas was built specifically for businesses that have experienced the frustrations described in this article. It is a full-service Google Ads management service that replaces your agency, freelancer, or in-house team entirely. AI agents run campaigns 24/7, and a dedicated human account manager oversees your strategy, answers your questions, and makes the cross-campaign decisions that no automated system can make on its own.
The difference between groas and a traditional agency comes down to coverage, cost, and incentive alignment. An agency gives you a human who checks your account during business hours, probably alongside dozens of other accounts. groas gives you AI that never stops optimizing, backed by a human strategist who knows your business. You get better results at a fraction of the cost, with zero work required on your side.
If you recognize multiple signs from this list in your own agency relationship, the most expensive thing you can do is wait. Every month of underperformance is budget that could have driven real results. groas offers a full hands-on account audit as part of its onboarding process, so you get a clear picture of what is working, what is broken, and what needs to change before any optimization begins. That audit alone is often more valuable than months of agency management.
The best time to fix a broken agency relationship was six months ago. The second best time is now.
Frequently Asked Questions
How Do I Know If My Google Ads Agency Is Doing A Good Job?
Check your account's change history for the last 90 days, review search terms reports for irrelevant traffic, and compare your actual revenue growth to the metrics your agency highlights in reports. If the change history is sparse, irrelevant search terms are burning budget, and revenue has not moved despite positive-sounding reports, your agency is likely underperforming. A good agency makes frequent, documented changes, proactively manages negative keywords, and ties their reporting to business outcomes rather than vanity metrics.
Should I Fire My PPC Agency?
If you recognize three or more of the warning signs outlined in this article, it is worth having a serious conversation with your agency and setting a clear performance timeline. If you recognize five or more, the relationship is almost certainly costing you more than it is delivering, and you should begin planning a transition. Before firing your agency, make sure you have full ownership of your Google Ads account and have documented your current campaign structures, keyword lists, and conversion data.
What Should I Do Before Switching Google Ads Agencies?
Confirm that you have admin or owner-level access to your Google Ads account. Export your keyword lists, negative keyword lists, audience segments, and conversion actions. Document your current campaign structure and bid strategies. Calculate your true cost per acquisition by including the agency management fee in your total spend. This ensures that whoever takes over your account can make informed decisions without losing valuable historical data.
Is There A Better Alternative To A Traditional Google Ads Agency?
Yes. Autonomous Google Ads management services like groas replace traditional agencies entirely by combining AI agents that optimize campaigns 24/7 with a dedicated human account manager who handles strategy, communication, and cross-campaign decisions. This eliminates the core problems with traditional agencies: limited human bandwidth, misaligned incentive structures, and inconsistent account attention. With groas, you get continuous optimization at a fraction of the cost of an agency, with always-on support via Slack or email and bi-weekly strategy calls.
How Much Should Google Ads Management Actually Cost?
Pricing varies widely. Traditional agencies typically charge 15% to 20% of your ad spend or flat retainers ranging from a few thousand dollars per month to well over ten thousand. Freelancers are generally cheaper but offer limited availability and no backup coverage. A service like groas delivers senior-level strategic oversight plus 24/7 AI execution for a fraction of what most agencies charge, without the misaligned percentage-of-spend incentive. The right question is not just what management costs, but what your total cost per acquisition looks like once you include the management fee.
What Is The Difference Between Google's Built-In AI And An Autonomous Management Service?
Google's native AI features like Smart Bidding, Performance Max, and AI Max optimize tactics within individual campaigns based on Google's own signals. They are powerful but limited to campaign-level decisions. An autonomous management service like groas operates at the account level, making cross-campaign budget allocation decisions, managing negative keywords, testing creative, and adjusting strategy based on business context. groas pairs that AI execution with a dedicated human account manager who provides the strategic oversight Google's algorithms cannot.
Can I Audit My Google Ads Account Myself Without PPC Experience?
Yes. You can perform a basic health check in about 30 minutes. Log into your Google Ads account, review the change history for the last 90 days to see how active management has been, pull a search terms report to look for irrelevant queries eating your budget, and calculate your true CPA by dividing total spend plus management fees by qualified leads. These three checks will tell you a lot about whether your account is being actively and competently managed.
