Google Ads wasted spend for small business: 5 fixes
Five Google Ads settings send small business budgets to the wrong searches. See where each setting is, what to change, and a 20-minute check to run today.
Quick answer: Five settings cause most Google Ads wasted spend in a small business account. They are the location option, the networks on Search campaigns, broad match without negative keywords, auto-applied recommendations, and conversion goals that count the wrong actions. Each setting takes a few minutes to check. Fix all five before you add budget.

Google Ads wasted spend in a small business rarely comes from one bad keyword. It comes from settings that nobody changed after setup. Google defaults give wide reach. A small business with a fixed service area needs the opposite.
This guide names the five settings that we check first, with the place to find each one and the change to make. We checked each fact on Google’s Help Center on 21 October 2026.
Which Google Ads settings waste the most budget?
These are the five settings that we check first in any account. Each one sends spend to people who cannot buy, or trains the bidding system on the wrong result.
| Setting | Default or common state | What to change |
|---|---|---|
| Location options | Presence or interest | Presence |
| Networks on Search campaigns | Search partners on | Test, then keep or turn off. Leave Display off. |
| Keyword match type | Broad match | Phrase or exact match, plus negative keywords |
| Auto-apply recommendations | On in some accounts | Turn off the items that add reach or change bids |
| Conversion goals | Weak actions set as primary | Set only real leads and sales as primary |
Key takeaway: Five settings decide where your budget goes before any keyword or ad does.
Setting 1: Does your location option reach people outside your area?
Yes, if you kept the default. As of October 2026, Google’s default location option is “Presence or interest”. Google calls it the “default and recommended option”. It reaches people in your area, and also people who show interest in your area.
Google states that people show interest through the terms in their searches, recent visits, and content about the location. So a person in Perth who searches “bookkeeper Brisbane” can see the ad of a Brisbane firm that only serves local clients.
Where to find it: Google’s steps are to open Campaigns, select the Settings tab, expand Locations, and select Location options.
What to change: Select “Presence: People in or regularly in your targeted locations”, then save. Repeat for each campaign.
Key takeaway: If you only serve local customers, set every campaign to Presence.
Setting 2: Do your Search ads also run on partner sites and Display?
Partner sites, yes, unless someone turned them off. Google states that search partners are included by default when you create a Search campaign. Search partners are sites that partner with Google to show ads.
Display is a separate checkbox. Google’s Display Expansion page tells you to select “Include Google Display Network” in the Networks section to turn it on. When it is on, part of your Search budget goes to image and text ads on Display placements.
As of October 2026, Google changed how this works. The same page says that you can now set a High or Low priority tier for Display and an optional daily budget cap. From February 2027, Search campaigns with Display Expansion move to this model automatically.
Where to find it: Open the campaign Settings, then Networks.
What to change:
- Clear the Display Network box. If you want Display ads, run a separate Display campaign with its own budget.
- Keep Search partners on for now.
- In the campaign table, select the segment icon and choose “Network (with search partners)”.
- Compare cost per lead for Google Search and for search partners over 30 days or more.
- Turn search partners off if they spend money and bring no leads.
Key takeaway: Keep Display out of Search campaigns, and make search partners prove their value with data.
Setting 3: Are your keywords on broad match with no negative keywords?
If you kept the default, yes. Google states that broad match is the default match type that all your keywords are assigned. With broad match, ads can show on searches that are related to your keyword, not only searches with your words.
Google also states that Smart Bidding works best with broad match, because more searches give the system more data. In our view, that advice suits accounts with many conversions each month. A small account with a few leads gives the system little to learn from.
Where to find it: Open Campaigns, then Insights and reports, then Search terms. This report shows the real searches that triggered your ads.
What to change:
- Read the search terms report for the last 30 days. Sort by cost.
- Add each irrelevant term as a negative keyword. Google advises this step for any term that is not relevant enough to the products or services you offer.
- Add terms that are wrong for every campaign (for example “jobs”, “free”, or “course”) at account level. As of October 2026, account-level negative keywords apply to Search, Performance Max, Shopping, and other campaign types, up to 1,000 per account.
- Change your best keywords to phrase or exact match until you have steady conversion data.
Key takeaway: The search terms report shows where the money goes. Read it before you add any keyword.
Setting 4: Does Google apply recommendations without your approval?
Only if someone in the account turned on auto-apply. When it is on, Google applies the chosen recommendations regularly, without a review step.
The list of recommendations that Google can apply includes “Add broad match keywords” and “Remove redundant keywords”, and bid strategy changes such as Target CPA. Google also notes that auto-applying recommendations will not increase your budget. But it can change how the budget is spent.
Where to find it: Go to the Recommendations page in the Campaigns menu, then select “Auto-apply settings”. The History tab shows each recommendation that Google applied, and when.
What to change:
- Open the History tab. Note each change from the last 90 days.
- Uncheck each recommendation that adds keywords, changes match types, or changes bid strategies.
- Save.
Key takeaway: You approve each change that adds reach or changes bids. Do not give that decision to auto-apply.
Setting 5: Does your bidding count the right conversions?
Only if your primary conversion actions are real leads and sales. Bid strategies such as Maximize Conversions and Target CPA optimise your campaigns according to your business goals. They only know your goals from the conversions that you track.
Google uses two types of conversion action. A primary action can be used for bidding and reporting. A secondary action is excluded from the “Conversions” column used for bidding, and it shows in “All conversions”.
Waste starts when a weak action is primary, for example a page view or a click on a “Contact” button. The bidding system then finds more people who do that cheap action, not more customers.
Where to find it: Open the Goals menu, then Summary under Conversions.
What to change:
- Set only real leads and sales as primary: a submitted enquiry form, a call from an ad, or a booked appointment.
- Set page views and button clicks as secondary. You keep the data, but bidding ignores it.
- Make a test enquiry. Confirm that it shows as a conversion the next day.
Key takeaway: Smart Bidding chases the actions that you mark as primary. Mark only the actions that bring revenue.
How do you check all five settings in 20 minutes?
Do the checks in this order. For a small account, each step takes about four minutes.
- Goals: Confirm that only real leads and sales are primary.
- Auto-apply: Read the History tab. Uncheck the items that add reach.
- Locations: Select Presence in each campaign.
- Networks: Clear the Display Network box. Segment by network to test search partners.
- Search terms: Add the irrelevant terms as negative keywords.
Write down the date of each change. Then compare cost per lead for the 30 days before and after. Do not change the budget or bids in that period.
Key takeaway: One 20-minute check, done in the right order, gives you a clean account to measure.
Frequently asked questions
How much budget do small businesses waste on Google Ads?
No reliable public figure exists. Most published estimates come from agencies that sell audits, and the numbers vary widely. Measure your own waste. Open the search terms report for the last 90 days. Mark each term that could never become a customer, and add up its cost.
Should I turn off Google search partners?
Not without data. Google includes search partners by default in new Search campaigns. Segment your campaign table by “Network (with search partners)” and compare cost per lead for Google Search and search partners. If search partners spend money for 30 days or more and bring no leads, turn them off in the campaign Networks settings.
Is broad match always a waste for a small business?
No. Broad match can find good searches that you did not think of. The risk is broad match with weak conversion data and no negative keywords. If your account gets few conversions each month, start with phrase and exact match. Test broad match later, in one campaign, when your conversion tracking is correct.
What is the difference between primary and secondary conversions?
A primary conversion action shows in the “Conversions” column, and Google uses it for bidding. A secondary action shows only in “All conversions”, and bidding ignores it. Set real leads and sales as primary. Set softer actions, such as page views, as secondary so you keep the data without training the bidding system on it.
Do negative keywords work on Performance Max campaigns?
Yes, at account level. As of October 2026, Google states that account-level negative keywords apply to Search and Shopping inventory. This includes Performance Max, Shopping, Smart, Local, and App campaigns. You add them in Admin, then Account settings, then Negative keywords. Each account can have up to 1,000 account-level negative keywords.
Should my ads run 24 hours a day?
Not if nobody answers the phone at night. Google’s default ad schedule is “All day”, so ads can show at any hour. If your leads need a fast reply, set an ad schedule for the hours when your team can respond. Keep evening hours if your enquiry form works well after hours.
