Is Performance Max Wasting Money on Your Own Brand Searches?

Performance Max brand exclusions can help Shopify advertisers understand whether PMax is generating new sales or simply taking credit for customers already searching for their business.

Your Performance Max campaign is reporting a 500%, 700% or even 1,000% ROAS.

It looks fantastic.

But there is a question Shopify store owners often don’t ask:

How much of that revenue came from customers who were already searching for your business by name?

This matters because Performance Max can advertise to people searching for your brand.

Someone may already know your business. They might be a previous customer, have visited your website earlier, clicked an email, seen you on Instagram or simply be returning to buy something they already decided they wanted.

They search for your store by name.

A Performance Max ad appears.

They click it and buy.

Google Ads records the conversion and includes the revenue in your Performance Max results.

The sale is real.

But did Performance Max actually create that sale?

Or did Google Ads simply place itself in front of a customer who was already on their way to your website?

That’s the issue Shopify advertisers need to understand when assessing Performance Max.

A high reported ROAS doesn’t automatically mean Performance Max is generating the same amount of additional revenue for your business.

Quick answer: Should you exclude your brand from Performance Max?

Not automatically.

If your Performance Max campaign receives a significant amount of branded search traffic, you should investigate how much of its revenue comes from people already searching for your business.

For some Shopify stores, excluding their brand can provide a clearer picture of how effectively Performance Max is finding customers outside existing branded demand.

For others, branded Shopping ads remain valuable and should continue running.

The important thing isn’t simply to block your brand.

It’s to understand how much Performance Max relies on branded traffic and whether that traffic is making the campaign look more effective than it really is.

What is branded search traffic?

Branded search traffic comes from searches containing or clearly referring to your business, brand or branded products.

If your Shopify store was called Example Homewares, branded searches might include:

• example homewares

• example homewares sydney

• examplehomewares

• example homewares cushions

• example homewares lamps

• example homewares discount code

• example homewares delivery

• example homewares reviews

These searches are fundamentally different from searches such as:

• table lamps

• blue ceramic table lamp

• designer cushions australia

• linen throws

• homewares online

• decorative vases

• bedside lamps sydney

The second group represents people searching for products or solutions rather than specifically looking for Example Homewares.

That distinction matters.

Someone searching for your exact business name already has a level of awareness of your business.

Someone searching generically for a product may never have heard of you.

Winning the second customer can tell you much more about Google Ads’ ability to generate new demand for your store.

How Do Performance Max Brand Exclusions Work?

Yes, it can.

Performance Max uses Google’s advertising inventory across multiple channels and can serve ads against relevant Google searches.

That can include searches associated with your own brand.

This means a Shopify store can have Performance Max competing for traffic from people who were already actively trying to find the store.

That isn’t necessarily wrong.

There are situations where advertising on your brand makes commercial sense.

The problem starts when branded and non-branded results are mixed together and the advertiser assumes all reported Performance Max revenue represents customers generated by the campaign.

It doesn’t necessarily.

A simple example of how Performance Max can claim branded revenue

Imagine your Shopify store generates $100,000 per month.

You spend $10,000 on Performance Max.

Google Ads reports:

Advertising spend: $10,000

Conversion value: $60,000

ROAS: 600%

It would be tempting to conclude:

We spent $10,000 and Performance Max generated $60,000.

But suppose you investigate the campaign and discover that $25,000 of the reported conversion value involved customers searching for your brand.

Now the picture becomes more complicated.

You cannot simply assume the remaining $35,000 is incremental revenue either, but you now know that a substantial part of the headline 600% ROAS came from existing branded demand.

That’s useful information.

The question changes from:

“What ROAS did Performance Max report?”

to:

“How much additional profitable revenue did Performance Max help the business generate?”

That’s a much better question.

Attributed revenue and incremental revenue are not the same thing

This distinction is one of the most important concepts in Google Ads.

Attributed revenue

Attributed revenue is revenue that Google Ads assigns to an advertising interaction according to your conversion tracking and attribution settings.

Incremental revenue

Incremental revenue is revenue that would probably not have occurred without the advertising.

Those numbers are not automatically identical.

If someone discovers your Shopify store through a generic Google Shopping search, clicks an ad and buys, Google Ads may have played an important role in acquiring that customer.

If an existing customer searches your exact business name because they want to reorder, clicks your Performance Max ad and purchases, Google Ads can still receive attribution.

But the likelihood that advertising created that sale is very different.

This doesn’t mean the Google Ads reporting is false.

It means you need to understand what the reporting actually measures.

Why does branded traffic usually convert so well?

Brand searches often have extremely strong purchase intent.

The customer already knows something about you.

They may have:

• purchased previously

• visited your website

• seen your products on social media

• received an email from you

• been recommended by somebody

• seen your physical store

• compared your products previously

• added something to their cart earlier

• searched for you after seeing another marketing campaign

By the time they type your brand into Google, much of the marketing work may already have happened.

That’s why branded search traffic can produce:

• high conversion rates

• low cost per acquisition

• strong ROAS

• high revenue per click

Those metrics look great in Google Ads.

But easy-to-convert branded traffic can hide weaker performance elsewhere.

How branded traffic can inflate Performance Max ROAS

Imagine a Performance Max campaign generated:

$50,000 conversion value

from:

$10,000 advertising spend

The reported ROAS is:

500%

Now imagine $20,000 of the conversion value came from branded searches.

The remaining $30,000 came from everything else.

That doesn’t mean your “real ROAS” is automatically 300%.

Attribution isn’t that simple.

But it does tell us something important.

Performance Max is relying heavily on branded demand to achieve the headline 500% figure.

If you’re using that 500% ROAS to decide whether Performance Max is successfully acquiring new customers, you’re missing part of the picture.

Is Performance Max stealing sales from organic search?

“Stealing” is probably too strong.

A better description is that paid advertising can intercept demand that may otherwise have reached your website through another route.

For example, a customer searches your business name.

Without an ad, they might click:

• your organic Google listing

• your Google Business Profile

• a Shopping result

• another unpaid result

With Performance Max running, they might instead click the ad.

The eventual purchase can then be attributed to Google Ads.

That doesn’t prove the sale would definitely have happened without the ad.

Maybe a competitor was bidding aggressively on your brand.

Maybe your paid Shopping listing showed the exact product the customer wanted.

Maybe the ad genuinely increased the likelihood of conversion.

That’s why I don’t automatically remove branded traffic.

I investigate it.

Why Shopify store owners should care about this

Because you’re not trying to win a Google Ads reporting competition.

You’re trying to grow a profitable business.

Suppose your Performance Max ROAS increases from 400% to 600%.

That sounds excellent.

But what if:

• Google Ads spend increased

• branded traffic increased

• reported Google Ads revenue increased

• Shopify’s total revenue barely moved

I’d want to understand why.

One possibility is that Google Ads has become better at capturing and attributing existing demand rather than generating a comparable amount of additional demand.

This is why I always want Shopify data alongside Google Ads data.

What should you compare with Performance Max ROAS?

For an eCommerce account, I would normally look beyond Google Ads at:

Total Shopify revenue

Is store revenue actually increasing as advertising spend increases?

Total Shopify orders

Are you generating additional orders or simply seeing more existing orders attributed to Google Ads?

New customers

Are you attracting people who haven’t purchased previously?

Returning customers

How much revenue is coming from people who already know the business?

Conversion rate

Has website performance changed?

Average order value

Are campaign changes affecting the value of customers being acquired?

Gross margin

A high ROAS doesn’t necessarily mean a campaign is profitable if product margins are poor.

Advertising spend as a percentage of revenue

If ad spend rises much faster than total store revenue, I want to know why.

Branded versus non-branded search demand

How dependent is campaign performance on people already searching for your business?

Looking at these together gives you a much better picture than staring at the Performance Max ROAS column.

How do I find branded searches in Performance Max?

Google now provides substantially more Performance Max search-term visibility than it did when PMax first launched.

You can use the Performance Max search terms reporting and Search Terms Insights to investigate the searches generating traffic and conversions.

Start by looking for:

• your exact business name

• shortened versions

• common misspellings

• your website/domain

• business name plus product

• business name plus category

• business name plus location

• business name plus “reviews”

• business name plus “discount”

• business name plus “coupon”

• business name plus “sale”

• proprietary product or range names

Don’t simply ask:

“Is my brand appearing?”

Ask:

“How much of the campaign’s valuable traffic and conversion activity is associated with branded demand?”

That’s the commercially useful question.

Search Terms Insights vs the Performance Max search terms report

These shouldn’t be confused.

Search Terms Insights groups searches into categories and subcategories so you can understand broader customer demand.

The Performance Max search terms report provides more granular information about actual searches that triggered ads.

Google has also added additional Performance Max reporting that can help advertisers understand the relationship between search terms, landing pages and ad formats.

For investigating branded traffic, I would use these reports together rather than relying on one screen.

Check whether the traffic came through Shopping or text ads

This is particularly useful for Shopify advertisers.

A branded search isn’t automatically worthless just because it contains your business name.

Imagine somebody searches:

your brand + table lamp

A Shopping ad displaying the exact lamp, image and current price may provide genuine value.

That’s different from paying for a text ad when somebody simply searches:

your brand

Google’s Performance Max search-term reporting can provide ad-format information that helps distinguish between Shopping ads and text ads.

That gives you another level of information before deciding what to exclude.

What are Performance Max brand exclusions?

Brand exclusions allow you to tell Google that you don’t want a Performance Max campaign serving for searches associated with particular brands.

That can include:

• your own brand

• competitor brands

• partner brands

• other brands you don’t want the campaign targeting

Rather than trying to manually create every possible keyword variation, you create or use a Google Ads brand list and apply it to the campaign.

Google recommends brand exclusions when the objective is specifically to prevent Performance Max from serving against particular brands.

Brand exclusions vs negative keywords

This is an important distinction.

Brand exclusions

Best suited to controlling traffic associated with an identifiable brand.

They can cover variations that would be tedious to maintain manually.

Campaign-level negative keywords

Useful when you want a particular Performance Max campaign to stop appearing for irrelevant or unwanted searches.

Examples might include terms relating to:

• jobs

• careers

• free products

• manuals

• DIY

• second-hand products

The exact negatives obviously depend on the business.

Account-level negative keywords

These apply more broadly across eligible campaigns in the Google Ads account.

That means you need to be careful.

If you only want to control one Performance Max campaign, an account-level exclusion can be unnecessarily broad.

For your own brand, I would investigate Google’s brand-exclusion controls before simply throwing your business name into a large negative keyword list.

Do Performance Max brand exclusions include misspellings?

One of the major advantages of brand exclusions is that Google’s brand system can recognise brand variations more comprehensively than manually maintaining a list of negative keywords.

This can include common misspellings and other recognised versions of the brand.

That’s particularly useful for brands with names people frequently spell incorrectly.

Do brand exclusions work across different languages?

Google’s brand system can recognise brands across different languages and scripts.

That is another reason brand exclusions can be more appropriate than manually trying to build negative keyword lists for branded traffic.

For Australian Shopify stores selling internationally, this can become increasingly useful.

Can you exclude your brand from Performance Max Search but keep Shopping?

Yes.

This is one of the most useful options for eCommerce advertisers.

Retail advertisers using product feeds can apply brand exclusions to Performance Max Search text ads while allowing Shopping ads to continue appearing for those branded searches.

That gives you a middle ground.

Instead of:

Allow all branded traffic

or:

Block all branded traffic

you can potentially:

Restrict branded text ads while retaining branded Shopping ads.

For Shopify stores, that can make much more sense.

Why might you want branded Shopping ads?

Because Shopping behaves differently from a normal text advertisement.

A Shopping ad can immediately show:

• the product

• an image

• the price

• the retailer

• other relevant product information

For somebody searching specifically for one of your products, that can shorten the path to purchase.

It can also give you more control over the products displayed when somebody searches for your brand.

So I wouldn’t blindly remove branded Shopping traffic just because it contains your business name.

Again, look at the data first.

When would I consider excluding my own brand?

I’d investigate exclusion more seriously when:

• branded searches represent a large proportion of PMax conversions

• PMax ROAS looks exceptional but total Shopify growth is much weaker

• a dedicated Brand Search campaign already handles branded traffic

• the business has strong organic visibility for its own name

• you’re specifically trying to measure non-brand acquisition

• the campaign appears heavily dependent on returning customers

• you want cleaner separation between brand defence and customer acquisition

These are signals to investigate, not automatic rules.

When might I leave branded traffic in Performance Max?

I may leave it alone when:

• branded traffic is a small proportion of campaign performance

• branded Shopping ads are commercially valuable

• competitors are aggressively advertising against the brand

• the business wants maximum branded search visibility

• removing the traffic would create unnecessary complexity

• the account doesn’t have enough data to justify heavy segmentation

• testing indicates branded advertising contributes additional sales

There isn’t one correct campaign structure for every Shopify store.

Should you run a separate Brand Search campaign?

Often, yes, particularly once the account is large enough to justify clearer segmentation.

A dedicated Brand Search campaign can give you more control over:

• brand keywords

• bids

• budget

• ad messaging

• landing pages

• competitors

• impression share

• reporting

You can then analyse branded Search separately from campaigns designed to find customers searching for products rather than your business.

That makes the account easier to interpret.

But I wouldn’t create five campaigns where two would do the job just because a diagram on LinkedIn says that’s the “correct” structure.

Campaign complexity needs to earn its keep.

Will Performance Max ROAS fall if I exclude my brand?

Quite possibly.

That doesn’t automatically mean the change failed.

If you remove traffic that converts extremely easily, reported ROAS can decline.

Suppose:

Before brand exclusion

Spend: $10,000

Google Ads conversion value: $60,000

ROAS: 600%

After brand exclusion

Spend: $9,000

Google Ads conversion value: $38,000

ROAS: 422%

At first glance, performance looks considerably worse.

But now look at Shopify.

Suppose total monthly store revenue before the change was:

$100,000

And after the change it was:

$98,000

Google Ads reported $22,000 less conversion value, yet actual Shopify revenue only fell $2,000.

That would raise an obvious question:

Where did those other purchases go?

Some customers may have found the website through organic search, direct traffic or another route.

This simplified example doesn’t prove causation, but it shows why judging the test solely from Google Ads would be a mistake.

What if Shopify revenue falls sharply after excluding the brand?

That’s important too.

Don’t become so determined to prove Google Ads is taking too much credit that you ignore evidence going the other way.

If you exclude branded traffic and:

• total Shopify revenue falls materially

• branded sales decline

• competitors gain visibility

• conversion volume drops

• the decline persists beyond normal variation

then branded advertising may have been contributing more value than you assumed.

Restore or adjust the strategy and continue testing.

The objective isn’t to prove that branded advertising is bad.

The objective is to find out what actually works.

How long should you test a brand exclusion?

Don’t make the change on Monday and declare victory or failure on Tuesday.

Shopify sales fluctuate.

Weekends differ from weekdays.

Promotions affect conversion rates.

Pay cycles matter.

Seasonality matters.

Competitors change promotions.

Your product availability changes.

Google campaigns also need time to adapt after significant changes.

I would want enough data to compare meaningful periods, while checking that there wasn’t another major change happening simultaneously.

The larger the store and conversion volume, the faster you can usually learn.

For a smaller store with limited conversions, you need to be much more cautious about drawing conclusions from short periods.

Don’t change five things at once

This is one of the easiest ways to make Google Ads testing useless.

If you:

• exclude your brand

• increase the budget

• change tROAS

• restructure asset groups

• rewrite the feed

• start a sale

all in the same week, good luck working out what caused the result.

Make controlled changes where practical.

Then monitor both Google Ads and Shopify.

What happens if competitors bid on your brand?

This is one reason I don’t automatically tell clients to stop advertising on their own name.

If competitors appear above or around your organic listing, branded advertising may help protect valuable search-result visibility.

You should investigate:

• who is advertising

• how frequently they appear

• whether their offer is competitive

• your impression share

• your organic position

• whether branded paid traffic converts profitably

• whether Shopping visibility matters

Brand protection and customer acquisition are different jobs.

Ideally, your reporting should allow you to distinguish between them.

Is a 500% branded ROAS good?

Not enough information.

This is exactly the type of number that sounds useful but can be misleading without context.

A 500% ROAS means Google Ads recorded $5 of conversion value for every $1 of advertising spend.

It doesn’t tell you:

• your product margin

• fulfilment costs

• payment fees

• returns

• discounts

• customer lifetime value

• how much revenue was incremental

• whether the customer was new

• whether the customer would have purchased anyway

For one Shopify store, 500% might be excellent.

For another, it might barely cover the economics of the business.

Can a lower Performance Max ROAS actually be better?

Yes.

Suppose Campaign A produces:

700% ROAS

but mostly captures existing branded demand.

Campaign B produces:

400% ROAS

but brings in substantially more new customers searching generic product terms.

Depending on margins, repeat purchase behaviour and customer lifetime value, Campaign B could be more valuable to the business.

This is why blindly telling Google’s bidding system to maximise a headline ROAS number can sometimes work against the broader commercial objective.

Can a high target ROAS encourage this problem?

It can contribute to a campaign becoming conservative.

When you give an automated bidding system a demanding efficiency target, it needs to find conversion opportunities likely to achieve that target.

Existing high-intent demand can naturally be attractive.

That doesn’t mean setting a high target ROAS automatically causes branded traffic.

It means you should understand what types of conversions are helping the campaign achieve the target.

If the campaign only achieves your desired ROAS because it is heavily dependent on existing demand, scaling it may be much harder than the headline number suggests.

What should a Shopify business measure instead of ROAS alone?

ROAS is useful.

I use it every day.

I just don’t use it alone.

For a serious Shopify account, I want to understand:

• Google Ads spend

• Google Ads conversion value

• campaign ROAS

• total Shopify sales

• total orders

• new customer revenue

• returning customer revenue

• gross profit

• average order value

• conversion rate

• product-level performance

• branded search contribution

• non-branded search contribution

• overall marketing efficiency

Together, these tell a much more useful story.

A practical Performance Max branded traffic audit

If I suspected branded traffic was making a Shopify PMax campaign look better than it really was, I’d work through the account roughly like this.

Step 1: Check the search terms

Identify searches involving the business name and branded products.

Step 2: Look at conversion contribution

Don’t just count searches. Look at the conversions and value associated with branded demand.

Step 3: Separate Shopping and text-ad behaviour

Determine whether branded traffic is coming through Shopping ads, text ads or both.

Step 4: Compare Google Ads with Shopify

Look at total sales, orders, new customers and revenue trends.

Step 5: Check existing Brand Search

Determine whether another campaign is already designed to handle branded demand.

Step 6: Check competitors

Understand whether there is a genuine brand-defence reason to advertise.

Step 7: Review brand exclusions

Decide whether complete or format-specific brand control makes sense.

Step 8: Test carefully

Don’t simultaneously overhaul the rest of the account.

Step 9: Monitor total business results

Don’t judge success solely by whether Performance Max ROAS goes up or down.

Step 10: Keep reviewing it

Customer behaviour, competitors and campaign behaviour change over time.

The biggest mistake I see with Performance Max reporting

It’s treating attributed revenue as if it automatically equals revenue created by advertising.

It doesn’t.

Performance Max may be doing an excellent job.

It may be finding profitable new customers that your Shopify store would never have reached otherwise.

It may also be capturing some people who already know your business.

Both can happen inside the same campaign.

Your job is to understand the difference.
