Google Ads campaign settings can waste budget before anyone touches a bid, keyword, or ad. The costly problems are usually quiet: automatic recommendations, expanded networks, broad audience reach, or a conversion goal that rewards the wrong outcome. Audit these six settings first, then judge performance using qualified pipeline rather than the platform conversion count.
Google Ads campaign settings to audit first
The first Google Ads campaign settings to inspect are the ones that change account behavior without changing the campaign’s visible strategy. They decide whether Google can apply recommendations, reach beyond selected audiences, serve outside core Search inventory, or optimize toward a shallow event. A campaign can look stable in the interface while lead quality weakens in the CRM.
Here is the six-point audit at a glance:
| Setting or signal | What can change | What to verify | Decision rule |
|---|---|---|---|
| Auto-apply recommendations | Keywords, targeting, assets, bidding, and expansion options | Enabled recommendation types and change history | Disable any type that should require operator review |
| Optimized targeting | Reach beyond manually selected audience signals | Qualified CPA and downstream quality by campaign | Test only after the conversion signal is clean |
| Search Partners | Search ads can serve on partner inventory | Network-segmented qualified conversion performance | Opt out when downstream economics are consistently weaker |
| Display Expansion | Search budget can also reach Display inventory | Network setting, spare budget, and conversion quality | Keep Search-only when intent purity matters |
| Primary conversion goal | Smart Bidding chases the selected outcome | CRM stage, primary status, and campaign goal | Use the deepest reliable event with enough volume |
| Signal density | Sparse events make performance volatile | Monthly volume and conversion delay | Move one step up-funnel when the event is too rare |
These checks complement a full Google Ads audit and the broader 50-point Google Ads audit checklist. The difference is scope. A full audit diagnoses targeting, bidding, creative, structure, and measurement. This settings review is the preflight that confirms the account is still behaving the way the operator thinks it is. For subscription businesses, the Google Ads for SaaS guide connects that preflight to landing-page tests, CRM outcomes, and ongoing campaign operations.
1. Review auto-apply recommendations
Auto-apply recommendations let Google regularly implement selected recommendation types. That is not a hidden feature. Google documents how advertisers opt in, see which recommendations are active, inspect history, and turn individual types off in auto-apply settings.
The risk is not that every recommendation is wrong. The risk is that an approved category keeps making future changes without the person diagnosing performance realizing it. Google’s published list includes recommendations related to bidding, broad match, Search Partners, Display Expansion, targeting expansion, ads, and assets. Those are strategic decisions in a high-spend account.
Run this check:
- Open Recommendations and review Auto-apply settings.
- Record every enabled recommendation type.
- Open the History tab and compare recent applications with the account’s change log.
- Disable categories that should require an operator to review the evidence first.
- Keep a recurring review on the account checklist.
2. Control optimized targeting
Optimized targeting looks beyond selected audience segments to find people Google believes are likely to convert. Google says it is automatically enabled for supported campaigns and can be turned off in ad group settings. The selected audiences act as signals, not hard boundaries, according to Google’s optimized targeting documentation.
That expansion can help when the campaign has a reliable definition of a good customer. It is dangerous when the primary conversion is a form fill, raw call, or other shallow event. In that case, Google can find more people likely to complete the easy action while the sales team receives more weak leads.
TNT’s operating sequence is simple:
- Confirm the account sends qualified outcomes back from the CRM.
- Exclude existing customers or irrelevant groups when acquisition is the goal.
- Establish a qualified CPA baseline with tighter controls.
- Test optimized targeting on a defined budget.
- Compare qualified leads, SQLs, customers, and revenue with the control.
3. Segment Google Search Partners performance
Google Search Partners are sites and placements where Search ads can appear beyond Google Search. Google says partners are included by default in new Search campaigns and can be disabled in campaign network settings. Its own Search Network documentation also warns that clicks from partner sites may not always reflect highly targeted traffic.
This does not mean every account should turn partners off. It means every account should isolate the result. Segment campaign performance by network, then compare:
- Cost per qualified lead
- SQL or opportunity rate
- New-customer rate
- Revenue per conversion
- Spam, duplicate, and disqualification rate
A cheap form fill is not proof that the network works. If Search Partners generate lower reported CPA but weaker sales outcomes, remove the setting and push the budget toward inventory with clearer intent. If partner traffic produces qualified customers at target economics, keep it. The answer belongs in the downstream data.
4. Keep Display Expansion intentional
Display Expansion allows a Search campaign to use Display inventory. Google says it aims to use spare Search budget and can produce additional conversions at similar CPA, although behavior varies by bid strategy and budget conditions. The feature is enabled through the Display Network option described in Google’s Display Expansion guide.
The core issue is intent. Search responds to an active query. Display reaches people while they browse sites or apps. Those are different contexts, even if both appear under one campaign.
Use Display Expansion when the account has clean measurement, enough conversion history, and a specific reason to extend beyond Search. Leave it off when you need Search-only economics, strict message-to-query control, or clean incrementality analysis. If you test it, segment by network and compare qualified outcomes.
5. Fix the primary conversion signal
The primary conversion action tells Smart Bidding what outcome to pursue. Google defines primary actions as events that can be used for bidding when the related goal is selected. Secondary actions normally remain observational, as explained in Google’s primary and secondary conversion documentation.
If the account makes form fills primary, Google looks for more form fillers. It cannot infer which leads became qualified unless that data is passed back. A low cost per lead can therefore hide a rising cost per customer.
Choose the signal in this order:
- Map every event from form fill through revenue.
- Verify which events reconcile with the CRM.
- Remove duplicated, inconsistent, or easily gamed actions.
- Find the deepest event with enough monthly volume.
- Make that event primary for the campaigns that should optimize toward it.
- Keep deeper, lower-volume events available for reporting, values, or additional signal.
Our Google Ads conversion action framework covers this decision by campaign type. If the CRM and ad platform are not connected, start with server-side conversion tracking so the account can learn from business outcomes rather than browser events.
6. Protect signal density
A conversion event can be commercially perfect and operationally unusable if it happens too rarely. Three closed deals per month may be the outcome the company cares about, but one delayed deal can make the monthly signal swing sharply. Smart Bidding then has too little consistent feedback to separate a real pattern from noise.
Google does not publish one universal minimum that fits every campaign. TNT Growth uses 30 primary conversions in 30 days as a practical operating floor before trusting broader automated campaign behavior. Search can sometimes work with less because the query supplies explicit intent. PMax and Demand Gen usually need more signal because they reach across broader inventory.
When the deepest event falls below the workable floor, move one step up the funnel. For example, optimize toward showed-up calls instead of closed deals while keeping closed revenue in the reporting layer. As volume grows, test moving the primary signal deeper.
After a material goal change, hold unrelated bid and budget changes steady. Google says Smart Bidding may need one to two conversion cycles after conversion-goal changes. If you change the goal, budget, target, ads, and structure together, you cannot tell whether the signal improved performance.
How to run this settings audit yourself
A useful settings audit takes less time than rebuilding a campaign and prevents far more confusion. Run it at account takeover, before a major budget increase, after an unexplained quality drop, and at least quarterly on established accounts.
- Export the last 90 days of campaign, network, and conversion-action data.
- Reconcile Google Ads conversions with CRM stages and revenue.
- Check auto-apply settings and history.
- Review campaign network selections for Search Partners and Display Expansion.
- Check optimized targeting in each eligible ad group.
- Confirm campaign goals and primary conversion actions.
- Calculate monthly volume for each primary action.
- Write one decision per setting: keep, disable, or test.
- Make one material change at a time.
- Wait through the relevant conversion cycle before judging it.
Use our 3×3 Google Ads optimization matrix after this preflight. The matrix helps diagnose whether the remaining constraint is visibility, engagement, or conversion, so the next change addresses the real problem. Before merging campaigns to chase a conversion threshold, review how Google Ads Smart Bidding shares query-level learning across campaigns.
When not to change a Google Ads setting
Do not turn off an expansion feature only because one lead was poor. Do not move to a deeper conversion event when the CRM field is incomplete. Do not disable automation in a mature campaign when qualified results are stable and the setting has passed a controlled test.
Keep a setting when it produces qualified business outcomes. Change it when downstream evidence shows that it is widening reach, changing inventory, or steering bids toward the wrong outcome.
Also pause the audit when measurement is broken. If GCLIDs are missing, offline imports are delayed, or sales stages are inconsistent, fix the data layer before declaring any campaign setting good or bad.
The takeaway
Profitable Google Ads management often comes from the absence of quiet mistakes. Auto-apply recommendations, optimized targeting, Search Partners, Display Expansion, conversion goals, and signal density can all change account economics before a headline or bid is touched. Audit them first, verify them against qualified pipeline, and make each change deliberately.

Frequently asked questions
Which Google Ads campaign settings should you check first?
Start with auto-apply recommendations, campaign networks, optimized targeting, conversion goals, and the volume behind the primary conversion action. These settings can change where ads serve and what Smart Bidding treats as success. Check them before rewriting ads or changing bids because a weak signal or expanded network can make every later optimization harder to interpret.
Should you turn off Google Search Partners?
Do not treat Search Partners as automatically good or bad. Google includes partners by default and lets advertisers opt out at the campaign level. Segment performance by network and compare qualified conversion cost, not only platform CPA. Turn it off when partner traffic consistently produces weaker downstream outcomes after enough data has accumulated.
Should optimized targeting be turned off?
Optimized targeting can help mature campaigns find additional converters beyond selected audience signals, but it can also widen reach before the conversion data represents qualified customers. TNT Growth starts with it off when signal quality is uncertain, then tests it after qualified lead tracking, exclusions, and downstream reporting are working.
How many conversions do you need for Google Ads Smart Bidding?
Google does not publish one universal minimum for every campaign and bid strategy. TNT Growth uses 30 primary conversions in 30 days as a practical signal-density check for broader automated campaigns. If the deepest business event is too rare, move one step up the funnel while keeping deeper events visible for reporting and value.
Can Google Ads apply recommendations automatically?
Yes. Google Ads lets advertisers opt into auto-applying selected recommendations, including changes related to bidding, targeting, keywords, and expansion. Google says these can be reviewed and disabled in the Recommendations and Account Settings areas. Operators should confirm exactly which recommendation types are enabled and review the change history regularly.
