Every new Google Ads account ships with the same configuration. Google will tell you it is optimized. It is — just not for you.
I have audited hundreds of accounts over the years. The pattern never changes: a business launches Google Ads, leaves the default settings in place, and bleeds money on traffic that will never convert. Broad match keywords, Display Network opt-in, 24/7 scheduling, Maximize Clicks bidding. Every one of these defaults expands your reach, inflates your click volume, and fattens Google's revenue.
Ryder Meehan of Upgrow, a 15-year Google Ads veteran, says it plainly: "You lose a lot of control over your ads and account and give it over to Google, who definitely does not have you saving money as a goal."
This article is the tactical companion to Google's $264 Billion Conflict of Interest, which explains the structural incentives behind these defaults. Here, the focus is purely practical: what each setting does, what it costs you, and how to change it.
Before You Start: Expert Mode
Before we get to the 10 defaults, there is a prerequisite that determines whether you even have access to fix them.
When you create a new Google Ads account, Google pushes you toward Smart Campaigns — a simplified interface that hides most of the controls covered in this article. Smart Campaigns provide minimal control, no keyword bid limits, and limited visibility into where your budget is spent.
Fix: During account creation, look for the option to "Create an account without a campaign" or "Switch to Expert Mode." Choose Expert Mode.
As Ryder Meehan notes: "If Google Ads is warning you that something is difficult or not advised, it is probably better."
If you already have a Smart Campaigns account, you can switch to Expert Mode in your account settings. Do this before anything else.
Default #1: Broad Match Keywords
The Problem
When you add keywords to your campaign, Google defaults to broad match — the loosest match type. Broad match allows Google's algorithm to show your ads for any search Google considers semantically related to your keyword.
In practice, this means:
- A plumbing service targeting "plumber" appears for "plumber meme," "plumber salary," and "how to do your own plumbing"
- A luxury watch store targeting "luxury watches" triggers ads for "watch repair" and "watch parts"
- A dental veneer company receives recommended keywords like "smile teeth" — misaligned with specific service targeting
As TG Digital explains: "Broad Match is a classic example of false efficiency. It feels like it's working because your cost-per-click drops, but your cost-per-acquisition skyrockets."
The Data
- 23-34% of traffic from broad match is irrelevant (GROAS.ai negative keyword analysis)
- Between June 2023 and June 2025, broad match CPCs rose 29% while phrase match surged 43% (TG Digital)
- A broad match keyword like "plumber near me" at $2/click on a low-intent search will not convert, while the same keyword on a high-intent search at $12/click converts well — broad match treats both equally
How to Fix It
Step 1: Navigate to your campaign's keyword list.
Step 2: For each keyword, change the match type:
- Exact match: Wrap in brackets —
[emergency plumber downtown] - Phrase match: Wrap in quotes —
"emergency plumber"
Step 3: Start with exact match for your highest-converting keywords. Add phrase match for coverage on variations.
Step 4: Only add broad match after you have 30-50+ monthly conversions and can pair it with Smart Bidding (Target CPA or Target ROAS) to let the algorithm adjust bids by query quality.
The recommended approach:
- Phase 1 (Foundation): Exact and phrase match only. Build conversion data.
- Phase 2 (Expansion): Layer in broad match on proven campaigns with Smart Bidding.

Default #2: Google Display Network Enabled
When you create a Search campaign, Google automatically opts you into the Google Display Network — over 2 million websites and apps where your text ads appear as banner-style placements. Search ads reach people actively looking for your service. Display ads reach people scrolling through random websites. The intent gap is massive.
Michelle Morgan, Co-Founder of Paid Media Pros, is unequivocal: In "99 out of 100 cases," Display Network performance in Search campaigns is "pretty terrible."
| Metric | Search Network | Display Network |
|---|---|---|
| Average CVR | 7.52% | 0.77% |
| Median ROAS | 5.17 | 0.12 |
| User Intent | Active search | Passive browsing |
| Click Quality | High | Low (bot activity common) |
That is a 43x difference in ROAS. Display traffic dilutes your data, inflates your impressions, and consumes budget that could have driven actual conversions. Marlin SEM adds that Display ads in Search campaigns are "prone to bot activity producing spam leads."
Fix: Campaign settings > Networks > uncheck "Google Display Network." If you want Display ads, run them as a separate campaign with their own budget. Never mix Display with Search.
Default #3: Search Partners Network Enabled
Google Search Partners includes sites like Amazon, Walmart.com, and hundreds of smaller search engines and directories. Unlike Display Network, Search Partners are not universally terrible. But performance varies wildly by industry, and Google enables them without telling you what quality of traffic to expect.
Upgrow describes the traffic source as "lower-end search engines." Some campaigns see reasonable results. Others see pure waste. You will not know which category yours falls into until you isolate the data.
Fix: Campaign settings > Networks > uncheck "Include Google search partners." Run for 30-60 days without them. Then, if you want to test: Campaigns > Segment > Network. Compare Search Partner metrics against Google Search side by side. If the numbers hold up, re-enable. The point is making an informed decision, not accepting a default one.
Default #4: Location Targeting — "Presence or Interest"
This one might be the most expensive default on the list. I have seen a single mislocated click in the legal industry burn through more budget than an entire day of legitimate traffic.
Google's default geo-targeting is "Presence or Interest." That means your ads show to people in your target location AND people who have merely shown interest in it. Someone in another country who searched for hotels in your city? They could see your ad for emergency plumbing. They will never become a customer, but you pay for the click anyway.
Michael Marlin Jr. of Marlin SEM puts a number on it: "Your ad could appear to someone searching for an attorney in New York simply because they recently researched hotels in Philly." Attorney CPCs exceed $100 per click.
Fix: Campaign settings > Locations > Location options > switch to "Presence: People in or regularly in your targeted locations."
For local service businesses, also set specific geographic targeting:
- Enter specific cities, zip codes, or set a radius around your business
- Start with a 5-mile radius and expand based on data
- Consider a layered radius approach: 3 miles (+75% bid), 5 miles (+50% bid), wider radius (standard bid)
Fix this on every campaign you create. No exceptions.
Default #5: Ad Schedule — 24/7
The Problem
Google runs your ads 24 hours a day, 7 days a week by default. For businesses that depend on phone calls, appointments, or real-time response, this means paying for clicks at 2 AM when no one can answer the phone or respond to a lead.
The Data
GrowthSpree's audit of 43 enterprise B2B accounts found:
- Off-hours waste rate: 67.8% — the vast majority of late-night and early morning clicks never convert
- 2-6 AM conversion rate: 0.01% — effectively zero
- Weekend overspending: $2.97 million annually across 43 accounts
- Sunday conversion rate: 0.8% vs. weekday average of 2.7% — a 3.4x difference
For phone-dependent service businesses, the math is even more stark. If your business closes at 6 PM and a potential customer clicks your ad at 11 PM, they hit a closed office, get no response, and you pay full CPC for nothing.
As Marlin SEM puts it: "Why waste money on people who click at 11pm and can't call you?"
How to Fix It
Step 1: Go to campaign settings.
Step 2: Under "Ad schedule," click "Edit ad schedule."
Step 3: Set your ads to run only during business hours. For most service businesses, this means Monday-Friday, with adjusted hours for Saturday if you operate on weekends.
Step 4: After accumulating 3-6 months of data, refine further with dayparting:
- Review conversion data by hour and day of week
- Increase bids during peak conversion hours
- Decrease bids (or pause) during low-conversion periods
For B2B service businesses: Data consistently shows Monday-Friday, 7 AM-4 PM as the highest-converting window.
For B2C businesses: Performance tends to be flatter across hours, so 24/7 scheduling may be less wasteful. But still review your data — few businesses convert equally at 3 AM and 3 PM.
Budget note: Google allows up to 6 ad schedule segments per day per campaign. This gives you granular control over when your ads run and at what bid adjustments.
Default #6: Optimize Ad Rotation
The Problem
Google's default ad rotation setting is "Optimize: Prefer best-performing ads." This sounds logical — why wouldn't you want Google to show your best ad? The problem is in how Google defines "best-performing."
Google optimizes for clicks (CTR), not conversions. And it makes this determination quickly, often sending 80% of traffic to one ad based on early data, preventing any meaningful A/B testing.
The Data
Upgrow documented the effect: one ad gets "80% of traffic purely because Google thinks it might perform better," preventing fair testing of alternative ads.
This matters because the ad with the highest CTR is not always the ad with the highest conversion rate. An ad promising "Free Quote — No Obligation" may get more clicks than "Professional Service Starting at $200" — but the second ad pre-qualifies prospects and generates higher-quality leads.
With optimized rotation, you'll never know. Google shows the clickier ad and moves on.
How to Fix It
Step 1: Go to campaign settings.
Step 2: Under "Ad rotation," change from "Optimize" to "Do not optimize: Rotate ads indefinitely."
Step 3: Run each ad for a statistically significant period — a minimum of a few hundred clicks or 1,000 impressions per ad — before making performance decisions.
Step 4: Use the Ad Variations feature (Campaigns > Experiments > Ad Variations) for structured testing. This hidden feature enables controlled A/B testing of specific ad elements.
Testing framework: Test one element at a time (headline, description, CTA). Weekly testing cadence is recommended, with a review session on Friday mornings (1-1.5 hours).
Default #7: Mobile App Placements Enabled
The industry calls them "fat-finger clicks." Your ads appear inside mobile games, utility apps, even children's apps — and users accidentally tap them while trying to play or navigate. Zero purchase intent. Near-zero conversions. Pure waste.
This affects Display campaigns and any campaign where the Display Network is still enabled (which, if you skipped Default #2, means your Search campaign too).
Fix: Content > Placements > Exclusions > add adsenseformobileapps.com as a blanket exclusion, or exclude specific app categories. Check placement reports regularly — some app placements will slip through.
Default #8: Automated Ad Extensions
Google can auto-generate sitelinks, callouts, and structured snippets by pulling text from your website. Upgrow describes the results as "weird and clunky-looking." Marlin SEM found that "Dynamic Sitelinks may redirect to irrelevant pages" — blog posts, about pages, terms of service. Not conversion pages.
| What Google Auto-Creates | What You Should Create Instead |
|---|---|
| Random sitelinks from website crawl | Links to your 4 best conversion pages (+10-15% CTR per PPC Chief) |
| Generic callouts | Specific value props: "24/7 Emergency Service," "Licensed & Insured" |
| Auto-generated snippets | Curated service categories |
| Nothing for calls | Call extensions showing your phone number (70% of mobile searchers use click-to-call) |
Fix: Ads & Extensions > Extensions > Automated Extensions > Advanced options > turn off all automated types. Then create manual versions of each extension that serve your conversion strategy.
Default #9: Google's Recommended Budget
The Problem
When you set a campaign budget, Google frequently recommends a higher amount. These recommendations appear as persistent notifications in your account and contribute to your Optimization Score.
Google's recommended budget is aligned with Google's revenue targets, not your ROI targets.
The Data
Marlin SEM states clearly: "Recommendations are just general guidelines; Google does not have you saving money as a goal."
The Optimization Score system amplifies this. Budget increase recommendations can add significant percentage points to your score, creating psychological pressure to spend more. But as we documented in Google's $264 Billion Conflict of Interest, dismissing these recommendations increases your score just as effectively as accepting them.
Google can also spend up to 2x your daily budget on high-traffic days (with the promise of averaging out over the month). This means a $50/day budget could see $100 days — and if you pause the campaign mid-month, the averaging never happens.
How to Fix It
Step 1: Set your budget based on your business economics, not Google's suggestions.
Step 2: Use this formula: Monthly Budget / 30.4 = Daily Budget
Step 3: For Target CPA campaigns, ensure your daily budget is 3-5x your target CPA. Below this, Smart Bidding doesn't have enough room to optimize.
Step 4: Dismiss budget recommendations in the Optimization Score without implementing them. Your score will still improve from the dismissal.
Budget framework based on monthly spend:
| Monthly Budget | Recommended Approach |
|---|---|
| $200-$600 | Single campaign, single service, single geo, exact match |
| $600-$1,500 | 1-2 campaigns, focused geo, aggressive negative keywords |
| $1,500-$3,000 | 2-3 campaigns, 70-20-10 rule, start testing automation |
| $3,000-$7,500 | Multiple campaigns, automated bidding (with sufficient data), broader testing |
| $7,500+ | Full portfolio strategy, Target ROAS/CPA, geographic expansion |
Default #10: Maximize Clicks Bidding
The Problem
When you create a new campaign, Google's default bidding strategy is often Maximize Clicks — which tells Google to get as many clicks as possible within your budget.
The problem: clicks are not conversions. Maximize Clicks optimizes for click volume without any consideration of whether those clicks will convert into leads, calls, or sales.
The Data
Upgrow found that Maximize Clicks results in "so few conversions that it is not worth it" despite driving high click volume.
The math makes this clear:
Maximize Clicks scenario:
- Budget: $3,000/month
- Strategy: Maximize Clicks
- Average CPC: $3.00 (Google finds cheap clicks)
- Clicks: 1,000
- Conversion rate: 2% (low-quality traffic)
- Conversions: 20
- Cost per conversion: $150
Manual CPC scenario:
- Budget: $3,000/month
- Strategy: Manual CPC, focused on high-intent keywords
- Average CPC: $6.00 (higher-quality traffic)
- Clicks: 500
- Conversion rate: 8% (higher-intent traffic)
- Conversions: 40
- Cost per conversion: $75
Half the clicks, double the conversions, half the cost per conversion.
How to Fix It
Step 1: Go to campaign settings.
Step 2: Under "Bidding," change from "Maximize clicks" to "Manual CPC."
Step 3: Set individual keyword bids based on the value of each keyword to your business. High-intent keywords (like "emergency plumber near me") deserve higher bids than informational keywords.
Step 4: Graduate to automated bidding only when you have sufficient conversion data:
| Monthly Conversions | Recommended Strategy |
|---|---|
| Less than 15 | Manual CPC (build data) |
| 15-30 | Maximize Conversions (no target) |
| 30-50 | Add Target CPA (set 5-10% above current average) |
| 50+ | Target CPA or Target ROAS |
Critical rule: Never switch bidding strategy and increase budget simultaneously. Make one change at a time and wait 2-4 weeks for the learning phase to complete.
The Complete Settings Audit Checklist
Use this checklist whenever you create a new campaign or audit an existing one:
Campaign Creation (Fix Before Launch)
- Expert Mode enabled (not Smart Campaigns)
- Keywords set to exact or phrase match (not broad)
- Display Network unchecked in Networks
- Search Partners unchecked in Networks

- Ad rotation set to "Do not optimize"
- Bidding set to Manual CPC (not Maximize Clicks)
- Budget set based on your economics, not Google's recommendation
Account-Level Settings (Fix Once)
- Auto-apply recommendations all disabled (see our auto-apply guide)
- Automated extensions turned off
- Mobile app placements excluded
- Conversion tracking properly configured before spending
Post-Launch Verification (First 7 Days)
- Search Terms Report reviewed — irrelevant queries identified and added as negatives

The Cumulative Impact of Default Settings
Each default setting individually drains budget. Together, their impact compounds.
Consider a service business spending $5,000/month with all defaults left in place:
| Default Setting | Estimated Waste | Monthly Cost |
|---|---|---|
| Broad match keywords | 23-34% irrelevant traffic | $1,150-$1,700 |
| Display Network enabled | Near-zero conversions on Display spend | $200-$500 |
| Search Partners | Variable, potentially 5-15% waste | $250-$750 |
| Presence or Interest geo | Out-of-area clicks | $100-$300 |
| 24/7 scheduling | Off-hours zero conversion clicks | $250-$500 |
| Maximize Clicks bidding | Low-quality traffic focus | $500-$1,000 |
| Missing negative keywords | Irrelevant search triggers | $300-$600 |
| Total estimated waste | $2,750-$5,350 |
These estimates align with industry data. PPC Land found the average account wastes $1,127.54/month (33%+ of budget) across their analysis of 15,000 accounts. GrowthSpree found a 36.1% average waste rate across 43 enterprise B2B accounts.
The waste is real, it is quantifiable, and it is fixable.
The Missing Protection: Negative Keywords
The 10 defaults above are settings Google configures incorrectly. But there is one critical protection Google does not configure at all: negative keywords.
Negative keywords tell Google which searches should NOT trigger your ads. Without them, your campaigns are defenseless against irrelevant traffic.
The Scale of the Problem
- 25% of accounts have zero negative keywords (PPC Land, 15,000 account analysis)
- Accounts with negative keywords convert at 13% vs. 4.6% without them — a 3x improvement with zero additional ad spend
- 84% of advertisers use fewer than 50 negative keywords, missing the opportunity to eliminate 23-34% of irrelevant traffic (GROAS.ai)
- Businesses with 200+ negative keyword strategies see 67% lower cost-per-acquisition
What to Exclude
Build your negative keyword list from these universal categories:
Free/Cheap Seekers: free, cheap, discount, budget, affordable, DIY, how-to, tutorial
Job Seekers: job, jobs, career, employment, hiring, salary, resume, freelance
Students/Researchers: school, university, student, research, thesis, homework, course, degree
Geographic Mismatches: international, worldwide, overseas, foreign (for local businesses)
Informational Intent: what is, how does, definition, meaning, example, history
How to Build and Maintain
Week 1-2: Deploy universal negative keywords across all campaigns (the categories above).
Week 3-4: Add industry-specific exclusions based on your Search Terms Report.
Ongoing: Review the Search Terms Report weekly. Every irrelevant query you find should become a negative keyword. Monthly search term reviews identify 15-25 new negative keyword opportunities on average.
Match type strategy for negatives:
- Broad match negative: For obviously irrelevant terms (e.g., "free" for a paid service)
- Phrase match negative: For specific irrelevant phrases (e.g., "how to" for a professional service)
- Exact match negative: For precise exclusions where you want to keep valuable variations
The ROI of Negative Keywords
GROAS.ai's analysis across their client base found that comprehensive negative keyword management generates 400-800% ROI and reduces wasted spend by 23% overall. For medium-sized businesses, this translates to $8,400-$23,700 in monthly savings.
This is the highest-impact, lowest-cost optimization available in Google Ads. It costs nothing to implement and delivers immediate results.
The Device Trap: An 11th Hidden Default
This is not technically a "default setting." But most advertisers never touch it, and the waste can be brutal.
The Problem
Google distributes your ads across all devices by default: desktop, mobile, and tablet. For many service businesses, not all devices convert equally.
The Data
GrowthSpree's analysis of 43 enterprise B2B accounts found:
- Mobile waste rate in enterprise B2B: 96.7% — nearly all mobile clicks failed to convert
- Desktop conversion rate vs. mobile: 4.31% vs. 3.48% (PPC Chief)
- Tablets often generate volume with zero conversions (WordStream)
For B2B service businesses, the pattern is consistent: desktop converts best, mobile is moderate, and tablets are often pure waste.
How to Fix It
Step 1: Go to Campaigns > Devices to view performance by device.
Step 2: Compare conversion rate, CPA, and ROAS across desktop, mobile, and tablet.
Step 3: Apply bid adjustments:
- If tablets show zero conversions over 30+ days: set -100% bid adjustment (effectively pausing tablet ads)
- If mobile converts significantly worse than desktop: reduce mobile bids by 20-50% based on the conversion rate differential
- If mobile converts well (especially for click-to-call campaigns): maintain or increase mobile bids
Step 4: Reassess monthly. Device performance can shift seasonally or as you optimize landing pages for different devices.
Note for service businesses: If phone calls are your primary conversion action, mobile may actually outperform desktop. 76% of Google Ads spending came from mobile devices in 2024, and 70% of mobile searchers use click-to-call. Test before reducing mobile bids.
Why Google Defaults to These Settings
Why does Google set things up this way? The answer is consistent across every single default.
As the Define Digital Academy explains: "Google's default recommendations suit high-spending advertisers with six-figure budgets, where individual setting miscalculations have minimal impact due to large data volumes. For small and medium-sized businesses, these same defaults can mean the difference between a profitable campaign and throwing money down the drain."
Each default serves a consistent purpose:
| Default | Google's Benefit | Your Cost |
|---|---|---|
| Broad match | More auctions entered = more clicks = more revenue | Irrelevant traffic |
| Display Network | Monetizes Display inventory with Search budgets | Near-zero conversions |
| Search Partners | Monetizes partner network with your budget | Variable-quality traffic |
| Presence or Interest | Larger audience = more impressions/clicks | Out-of-area clicks |
| 24/7 scheduling | Maximum impression/click opportunity | Off-hours waste |
| Optimize rotation | Higher CTR = more clicks | Less testing, potentially lower conversion rates |
| App placements | Monetizes app inventory | Accidental clicks |
| Automated extensions | More ad real estate = more clicks | Irrelevant link destinations |
| Recommended budget | Higher budgets = more Google revenue | Overspending beyond ROI |
| Maximize Clicks | Maximum click volume = maximum Google revenue | Low conversion rates |
The pattern is consistent: every default expands reach and increases click volume. Google charges per click. More clicks = more Google revenue.
