Is My Google Ads Agency Wasting My Money? 15 Warning Signs

Quick Answer

If you’re worried about a Google Ads agency wasting money in your account, there are several warning signs worth checking. The problem is that poor Google Ads management does not always look like a disastrous account.

You can still see conversions, traffic and a reasonable ROAS while tracking errors, irrelevant searches or weak campaign decisions quietly burn through budget.

Poor Google Ads management does not always look like a disastrous account.

Sometimes the account appears healthy.

Conversions are being reported. Performance Max has a reasonable ROAS. Traffic is increasing. Your monthly report has plenty of graphs.

But underneath those numbers, Google may be counting the wrong conversions, Performance Max may be taking credit for sales that would have happened anyway, irrelevant searches may be consuming budget, weak products may be getting too much spend, or nobody may be checking what happens after the click.

The real question is not:

“Is my Google Ads account getting conversions?”

It is:

Google Ads Agency Wasting Money: What Should You Check First?

The clearest signs of a Google Ads agency wasting money are unreliable conversion tracking, irrelevant search terms, poor product-level performance, misleading Performance Max results and an inability to explain where the budget is going.

I spend a lot of time reviewing existing Google Ads accounts, and the biggest problems are often not obvious from the top-line numbers.

One of the strongest signs of a Google Ads agency wasting money is when reported performance looks good but actual business revenue tells a different story.

Here are the warning signs I would look for.

1. You Cannot Explain What Google Ads Is Actually Counting as a Conversion

This is one of the first things I would check in any Google Ads account.

Ask your agency a simple question:

What exactly counts as a conversion in my account?

For an eCommerce store, the obvious primary conversion will usually be a completed purchase.

For a lead-generation business, it might be a genuine enquiry form, qualified phone call or another meaningful business action.

Problems begin when less valuable actions are treated as if they have the same importance.

An add to cart is not a sale.

A visitor beginning checkout is not a sale.

Someone looking at your contact page is not a lead.

A five-second phone call is probably not a qualified enquiry.

Yet I see accounts where these types of actions are included in the headline conversion numbers.

That can make performance look significantly better than it really is.

It can also cause a bigger problem.

Google’s automated bidding systems use primary conversion actions to help decide what behaviour to optimise towards. Google distinguishes between primary conversion actions, which can be used for bidding, and secondary actions that are generally there for observation.

If an add to cart, page view or low-quality action has accidentally been made a primary conversion, Google can start finding more people likely to perform that action.

That does not necessarily mean it will find more customers.

Before trusting CPA, conversion volume or ROAS, make sure you understand exactly what is being counted.

2. Google Ads Reports Far More Sales Than Your Business Is Actually Receiving

Some difference between Google Ads, Shopify, GA4 and your accounting figures is completely normal.

They use different attribution models and reporting methods.

But large unexplained discrepancies deserve investigation.

Imagine Google Ads is reporting excellent results while your actual business revenue is flat or falling.

That is not something an agency should simply dismiss by saying:

“Google uses a different attribution model.”

That might be part of the explanation, but it is not enough.

You need to understand where the gap comes from.

Possible causes include duplicate purchase tracking, imported GA4 conversions sitting alongside native Google Ads conversions, incorrect revenue values, multiple purchase actions being included, attribution differences, branded searches, or Google receiving credit for customers who were already on their way to buying.

For Shopify stores, compare Google Ads performance with actual Shopify orders and revenue.

They will never match perfectly.

They should still make commercial sense.

If Google Ads says advertising performance is fantastic but the bank account tells a different story, investigate the tracking before increasing the budget.

3. Your Agency Talks About Conversions But Not Profitability

Conversions are not the same as profitable conversions.

This is particularly important for eCommerce.

Suppose you spend $10,000 on Google Ads and generate $30,000 in tracked revenue.

A ROAS of 300% might sound good.

But is it?

That depends on your margins.

If your gross margin is 70%, you may have plenty of room.

If it is 25%, you may be losing money after advertising costs, shipping, payment fees, discounts, returns and operating expenses.

The same applies to lead generation.

A $100 lead might be excellent if one in three leads becomes a $10,000 customer.

It might be terrible if one in 30 leads becomes a $300 customer.

A good Google Ads manager should want to understand the economics of your business.

What is an acceptable cost per lead?

What percentage of leads become customers?

What is an average customer worth?

What is the gross margin?

What is your break-even ROAS?

Which product categories are most profitable?

Are new customers worth more than the first transaction suggests?

Without those answers, Google Ads can be optimised towards attractive dashboard numbers rather than profitable growth.

4. Nobody Is Regularly Looking at the Actual Search Terms

Keywords are not the same as search terms.

Your keyword is what you ask Google to target.

The search term is what the person actually typed.

That distinction matters enormously.

A campaign can contain sensible-looking keywords while still matching to terrible searches.

Google’s search terms report exists specifically so advertisers can see searches that triggered ads and identify irrelevant terms that should potentially be excluded.

For me, this is basic account hygiene.

If I am managing a Search campaign, I want to know what people are actually typing.

Not just once when the campaign launches.

Regularly.

Search behaviour changes. Google’s matching changes. New irrelevant terms appear. Broad match can uncover valuable searches, but it can also find traffic you would never knowingly pay for.

The agency should not blindly add hundreds of negative keywords either. Over-restricting a campaign can choke off useful traffic.

The point is that somebody should be looking.

If thousands of dollars are being spent each month and nobody can tell you what people are actually searching for, that is a warning sign.

5. Performance Max Is Being Treated Like a Set-and-Forget Campaign

Performance Max can work extremely well.

I use it extensively for eCommerce.

But the fact that Google automates much of the bidding and placement does not mean the manager has nothing to do.

Quite the opposite.

Automation increases the importance of the inputs, tracking and ongoing analysis.

A manager should still be thinking about campaign structure, conversion goals, product selection, product feeds, Merchant Centre, asset groups, brand traffic, search terms, budgets, bidding targets, landing pages and which products are actually producing profitable sales.

Google now provides detailed Performance Max search term reporting and recommends using it to understand what searches are triggering ads and which searches are generating conversions.

Performance Max also supports campaign-level negative keywords for Search and Shopping inventory.

So the old excuse that “Performance Max is a black box and there is nothing we can do” is becoming increasingly weak.

There is more visibility than there used to be.

A good manager should be using it.

6. Performance Max Is Taking Credit for Your Own Brand Searches

This deserves particular attention.

Imagine somebody already knows your business.

They search Google for your company name.

A Performance Max ad appears.

They click it and buy.

Google may report that as a Performance Max conversion.

Technically, the ad generated the click.

But did the advertising create the customer?

Probably not.

The customer already knew who you were.

This does not mean branded advertising is always bad. There are legitimate reasons to advertise on your own brand, particularly where competitors are bidding against you or you want greater control over the search results.

The problem is when branded sales are mixed into Performance Max results and used to prove that the campaign is generating strong incremental growth.

Google recommends using brand exclusions rather than simply negative keywords when the objective is to prevent Performance Max from serving against your own brand searches.

If your Performance Max ROAS looks spectacular, one of the first questions I would ask is:

How much of this revenue is coming from people searching for us by name?

Your agency should be able to discuss that.

7. Your Agency Never Talks About Google Merchant Centre

If you run an eCommerce business, Google Ads management does not stop inside Google Ads.

Google Merchant Centre matters enormously.

It controls critical product information Google relies on for Shopping and Performance Max.

That includes product titles, descriptions, prices, availability, identifiers, images, shipping information and other attributes.

Products can also become disapproved or limited.

If nobody is monitoring Merchant Centre, problems can quietly hurt performance.

A top-selling product might stop serving.

A price mismatch could create an issue.

Stock information might be wrong.

Shipping settings may be causing warnings.

Product identifiers might be missing.

Your feed might technically work but still be poorly optimised.

A manager who specialises in eCommerce Google Ads should understand Merchant Centre.

If every conversation with your agency starts and ends inside the Google Ads interface, they may be missing a substantial part of the job.

For more detail, see my guide to Google Merchant Centre problems that hurt Shopping Ads.

8. Nobody Is Looking at Which Individual Products Are Spending the Money

This is another common Performance Max and Shopping problem.

Your overall campaign might show:

Spend: $10,000
Revenue: $30,000
ROAS: 300%

Again, that looks reasonable.

But what happens when you break it down by product?

You might find that a small number of strong products are carrying the entire campaign.

Some products might be generating a 700% return.

Others might have spent hundreds of dollars without producing a single sale.

That distinction matters.

Not every product deserves equal advertising budget.

Some have stronger margins.

Some convert better.

Some are more competitively priced.

Some have better stock depth.

Some are excellent first purchases.

Some work well as organic or repeat-purchase products but make little sense for paid acquisition.

Good eCommerce Google Ads management should eventually get down to product-level performance.

Looking only at the campaign total hides too much.

9. Your Agency Keeps Increasing the Budget Without Fixing the Problems

Scaling a bad campaign does not fix it.

It makes the problem more expensive.

If an account is underperforming, increasing the budget can sometimes be appropriate, particularly if the campaign is constrained and already profitable.

But “Google needs more budget” should not be the automatic answer to every performance problem.

Before spending more, I would want to know:

Is conversion tracking reliable?

Are the right conversion actions being used?

Are search terms relevant?

Are the best products getting budget?

Are poor performers being identified?

Is the product feed competitive?

Are landing pages converting?

Is the bidding target realistic?

Are there stock or Merchant Centre issues?

Are brand conversions inflating results?

If those fundamentals are broken, more budget often means more waste.

You should scale what is working.

You should not use scaling as a substitute for diagnosis.

10. Your Reports Are Full of Numbers But Tell You Almost Nothing

A monthly report should help you understand the account.

It should not require a Google Ads certification to decipher it.

I am not impressed by reports with 25 charts if none of them answers the basic business questions.

What happened?

Why did it happen?

What changed?

Where is money being wasted?

What is improving?

What needs attention?

What did the manager actually do?

What happens next?

Clicks, impressions, CTR and average CPC can all be useful metrics.

They are not a strategy.

A business owner should finish reading a monthly report with a better understanding of the account than they had before opening it.

If the report looks impressive but you still have no idea whether the advertising is commercially healthy, it is not doing its job.

11. Nothing Ever Seems to Change in the Account

This one needs some nuance.

A good Google Ads manager does not need to constantly change campaigns just to prove they are working.

That can be just as damaging as doing nothing.

Automated bidding systems need enough stability to learn.

Google itself recommends giving certain automated features time to gather data rather than constantly interfering with them. For example, Google advises a learning period when evaluating AI Max changes before making further adjustments.

But stability is different from neglect.

Even when major campaign settings stay the same, there should still be monitoring, analysis and decision-making happening.

Search terms can be reviewed.

Budgets can be assessed.

Product performance can be checked.

Merchant Centre can be monitored.

Landing pages can be reviewed.

Conversion tracking can be checked.

Creative can be tested.

New opportunities can be investigated.

Seasonality can be planned for.

Poor products can be identified.

A manager does not need to fiddle with the account every day.

They do need to know what is happening.

12. Your Agency Blames Google Every Time Performance Drops

Google Ads performance fluctuates.

Sometimes Google changes.

Competition changes too.

Search demand changes.

Consumer confidence changes.

Competitors change prices.

Products go out of stock.

Seasonality changes.

Conversion rates move.

Websites break.

Tracking breaks.

Feeds break.

Offers become less competitive.

There are dozens of reasons performance can fall.

That is why “Google changed the algorithm” is rarely a satisfactory diagnosis on its own.

If performance suddenly drops, I want to investigate.

Did impressions fall?

Did CPC increase?

Did search demand change?

Did conversion rate decline?

Did Merchant Centre develop an issue?

Did products become unavailable?

Did the website change?

Did tracking change?

Did a competitor start discounting heavily?

Did the product mix change?

Did the campaign enter a learning phase?

Did the target ROAS become too aggressive?

A strong manager should be curious when performance changes.

Not defensive.

13. Nobody Looks at Your Website or Landing Pages

Google Ads does not end when somebody clicks the ad.

That is where half the battle starts.

You can have excellent targeting and still lose money because the landing page does not convert.

This is especially obvious with eCommerce.

Imagine paying for high-intent Shopping traffic, then sending customers to a product page with weak images, a vague description, unclear delivery costs, no reviews, poor mobile usability and an Add to Cart button buried halfway down the page.

Google Ads did its job.

The page did not.

The same problem exists in lead generation.

A visitor clicks an ad for a high-value service and lands on a page with no strong reason to contact the business, no proof, no useful information and a generic enquiry form.

Changing bids will not fix that.

Your Google Ads manager may not be your web developer.

That is fine.

But they should still recognise obvious conversion problems.

Campaign management and landing-page performance cannot be treated as completely separate worlds.

14. Your Agency Cannot Clearly Explain What They Are Doing

Google Ads is complicated.

Your explanation of Google Ads does not need to be.

A good manager should be able to explain why they are making a change in normal language.

For example:

“We are separating these products because this category has much stronger margins.”

“We reduced the target ROAS because it was restricting volume too aggressively.”

“We have excluded your brand from this Performance Max campaign so we can see how well it performs without relying on branded searches.”

“We found irrelevant searches consuming budget and added appropriate negatives.”

“The campaign is reporting more purchases than Shopify, so I want to check whether purchase tracking is duplicated before we make further bidding decisions.”

That is understandable.

Be cautious if every answer sounds like:

“The machine learning needs more data.”

“The algorithm is optimising.”

“The campaign is still learning.”

“Google recommends this.”

“We need to increase the budget.”

Those things can sometimes be true.

They are not explanations by themselves.

Your manager should understand the account well enough to explain what is happening and why.

15. Your Agency Follows Every Google Recommendation Automatically

Google Ads recommendations can be useful.

They can highlight issues worth investigating.

But recommendations are not instructions.

Google is an advertising platform.

Its incentives and yours overlap, but they are not identical.

Google wants advertisers to achieve results because unsuccessful advertisers eventually stop spending.

Google also benefits when advertisers spend more money.

That means every recommendation should be judged against your commercial goals.

A recommendation to increase budget may be excellent if the campaign is profitable and limited by budget.

It may be a terrible idea if tracking is unreliable and the campaign is already wasting spend.

Broad match can work extremely well in the right account.

That does not mean every keyword should automatically become broad match.

Performance Max can be excellent for eCommerce.

That does not mean every business should move everything into Performance Max.

Automation is a tool.

It is not a strategy.

How Can I Tell If My Google Ads Agency Is Doing a Good Job?

Do not judge your agency by how busy they appear.

Judge them by whether they understand the account and can connect advertising performance with real business results.

A good Google Ads manager should know what you are trying to achieve, understand the important conversion actions, monitor where money is being spent, investigate problems and explain their decisions clearly.

They should also be willing to tell you when the problem is not Google Ads.

Sometimes the website is weak.

Sometimes the offer is weak.

Sometimes pricing is uncompetitive.

Sometimes your budget is too small for the market.

Sometimes demand has dropped.

Sometimes your expectations are unrealistic.

I would rather tell a client that than hide behind another campaign restructure.

How Often Should a Google Ads Agency Optimise My Account?

There is no sensible universal answer such as “every day” or “every Tuesday”.

The right frequency depends on account size, spend, campaign type, conversion volume and how quickly conditions are changing.

An account spending $100 a day does not necessarily need the same attention as one spending $2,000 a day.

A stable Search campaign might require fewer major changes than a large eCommerce account with hundreds of products, changing stock and active promotions.

The important distinction is between monitoring and changing.

An account may be monitored frequently without settings constantly being altered.

That is often exactly what should happen.

The goal is not activity.

It is better decisions.

Should My Google Ads Agency Be Checking Search Terms?

Yes.

For Search campaigns, actual search terms are one of the clearest ways to understand the traffic you are buying.

They can uncover irrelevant queries, new keyword opportunities and changes in customer behaviour.

Performance Max now provides greater search-term visibility as well, including search terms and associated landing-page information.

That does not mean every unusual search should immediately become a negative keyword.

Overusing negatives can restrict campaigns unnecessarily.

But somebody should be reviewing the information.

Can Performance Max Make My Results Look Better Than They Really Are?

Yes.

Performance Max can generate legitimate incremental sales and can perform extremely well.

But its headline figures can sometimes make performance look stronger than the underlying commercial impact.

One common reason is branded traffic.

Another is conversion tracking.

If Performance Max is receiving credit for existing customers, branded searches or low-value conversion actions, the reported ROAS may not tell the full story.

That is why I prefer to look beyond the campaign total.

Which products generated the revenue?

How much came from new customers?

How much came from branded searches?

Does tracked revenue make sense compared with actual store revenue?

Which products consumed spend without selling?

What happened to overall business sales when ad spend changed?

Those questions give you a much better picture.

Should I Fire My Google Ads Agency If Performance Is Bad?

Not automatically.

Bad performance and bad management are not the same thing.

Even a well-managed account can go through difficult periods.

Demand falls.

Competitors become more aggressive.

Prices change.

Products go out of stock.

The website conversion rate falls.

Seasonality shifts.

What matters is how your agency responds.

If they identify the problem, explain it clearly, make sensible changes and keep you informed, that is very different from an agency that ignores the problem or hides behind vague explanations.

I would be more concerned about poor diagnosis than one bad month.

If you have lost confidence, an independent Google Ads audit can also make sense before you replace anyone.

You may discover the account needs a few specific fixes.

Or you may discover much bigger problems.

Either way, you are making the decision with evidence rather than frustration.

Should I Get an Independent Google Ads Audit?

If you are spending meaningful money and no longer trust the numbers, yes.

An independent audit can be particularly useful when performance has fallen, reported conversions do not match actual business results, you are unsure what your agency is doing, Performance Max results look suspiciously strong, lead quality has deteriorated, or you are considering moving to another manager.

The point of an audit should not be to criticise everything the existing agency has done.

Every account contains decisions that made sense at the time.

The goal should be to answer a more useful question:

What are the biggest opportunities or risks in the account right now?

That might involve conversion tracking.

It might involve campaign structure.

It might involve search terms.

It might involve Performance Max.

It might involve Merchant Centre.

It might involve product feeds.

It might involve the website.

Sometimes the audit confirms the account is actually being managed reasonably well.

That is useful information too.

What Should I Ask My Google Ads Agency?

If you are unsure about the quality of your management, you do not need to interrogate your agency with 50 technical questions.

Start with a few simple ones.

Ask them what Google Ads is currently optimising towards.

Ask which campaigns or products are generating the strongest results.

Ask where they believe budget is currently being wasted.

Ask what they changed in the last month and why.

Ask what they plan to test next.

Ask whether your conversion tracking has been checked recently.

Ask how much brand traffic is included in your Performance Max results.

Ask whether there are any issues in Google Merchant Centre.

Ask whether anything on your website is hurting conversion rates.

The quality of the answers will tell you a lot.

What Does Good Google Ads Management Actually Look Like?

Good management is not about constantly changing things.

It is about knowing what deserves attention.

Sometimes the right decision is to restructure a campaign.

Sometimes it is to leave the campaign alone.

Sometimes it is to exclude poor traffic.

Sometimes it is to lower the budget.

Sometimes it is to increase it.

Sometimes it is to fix Merchant Centre before touching the campaigns.

Sometimes it is to tell the client their website is the real problem.

Sometimes it is to admit that the advertising channel is not producing an acceptable return.

Google Ads management should involve judgement.

Automation can make thousands of bidding decisions.

It cannot understand your business as well as someone who knows your margins, priorities, customers, stock position and commercial goals.

That human layer still matters.
