When should I switch from Manual CPC to Maximize Conversions?

Switch after verifying that conversion tracking is reliable and the campaign has enough recent, representative data for its goal. Compare volatility and outcome quality before and after the change. Switching before the signal is reliable can create volatile results; monitor the account rather than assuming one failure pattern.

Is Target ROAS the right strategy for ecommerce?

Only when conversion-value tracking is reliable and the campaign has enough recent, representative data for its goal. Evaluate value quality and volatility before accepting the strategy. A Shopify account that passes revenue without margin context may optimize toward orders that do not match the profit goal; verify the value model before accepting Target ROAS.

What is the most common bid-strategy mistake I will find in my account?

A strategy can be misaligned with the campaign's goal, data quality, or conversion volume. Review auction behavior, spend, conversion quality, and CAC, then choose the appropriate controls; Manual CPC is one possible option.

Should I run different bid strategies on different campaigns in the same account?

Yes. Bid strategy is configured per campaign. Choose each strategy from that campaign's goal, signal quality, budget, controls, and measured results.

How long should I wait before changing a bid strategy?

After a bid-strategy change, use the campaign's status, conversion cycle, data volume, and volatility to set the evaluation window. Avoid reacting to an incomplete learning period, but do not assume one universal number of days.

The 20-Minute Google Ads Bid-Strategy Audit

Why bid strategy belongs in the audit

Bid strategy can remain unchanged while an account's goals, tracking, budget, and conversion data change. That makes strategy fit worth checking against the campaign's current evidence.

Bid strategy changes auction behavior and the controls available to the operator. Compare spend, conversion quality, CAC, value accuracy, and volatility before deciding whether the present strategy fits.

The 20-minute audit flags strategy-fit questions. It does not prescribe a universal strategy; it identifies the campaigns that need a deeper decision.

The audit, step by step

Open Google Ads. Go to Campaigns view. Filter for active campaigns only. For each campaign, do the following.

20-minute path The audit is a sequence, not a dashboard stare.

1StrategyOpen the active bid strategy on every campaign.

2VolumeCompare it to trailing 30-day conversions.

3ValueConfirm revenue or margin values are real.

4Auto-applyCheck whether Google changed strategy settings.

5DecisionSwitch, wait, or run the deeper marketing services.

Use this order. If you evaluate ROAS before checking strategy fit, you are scanning symptoms before the cause.

Step 1. Open the bid strategy column

Add the Bid Strategy column to your campaign view if it is not already there (Columns → Modify columns → Attributes → Bid strategy type). The strategy will be one of: Manual CPC, Enhanced CPC, Maximize Clicks, Maximize Conversions, Target CPA, Target ROAS, Target Impression Share, or Maximize Conversion Value.

Note the strategy for each campaign. Then move to step 2 and check the conversion volume.

Step 2. Check trailing 30-day conversions per campaign

Set a date range that covers the campaign's conversion cycle. Review conversions, conversion quality, value accuracy, budget, and volatility together.

Manual controls: review bid ceilings, auction coverage, and the operator time required to maintain them.
Maximize Conversions: review whether recent conversion data is representative, correctly tracked, and aligned with the campaign goal.
Target CPA: review conversion quality, target realism, budget constraints, and performance volatility.
Target ROAS: review whether purchase values reflect the business goal and whether recent data represents the products being sold.
Maximize Conversion Value: review value accuracy, product mix, budget, and outcome quality.

Flag campaigns where the current strategy does not match the available signal, controls, or business goal. Those are candidates for deeper review.

Use account evidence. The appropriate strategy depends on goal, signal quality, budget, controls, and observed results.

Step 3. Check whether conversion values are real

If any campaign is on Target ROAS or Maximize Conversion Value, ask one more question: are the conversion values you are passing to Google reliable?

Open Tools → Conversions. Look at each conversion action that the campaign optimizes against. Check the value column. If the value is "Use the same value for each conversion" set to a flat amount that does not reflect actual purchase value, the algorithm is optimizing against a fiction.

The Shopify default purchase event passes the order total. That is acceptable for revenue ROAS targeting if your gross margin is consistent across products. If margin varies materially by product, revenue-only values can reward high-revenue, low-margin orders. Consider whether margin-adjusted value better represents the business goal. That is its own setup project; the audit just tells you whether you are running on real values or guesses.

Step 4. Check the Recommendation tab for forced changes

Google Ads frequently recommends switching campaigns to Maximize Conversions or Target ROAS. Some of these recommendations get auto-applied if you have auto-apply enabled. Check Tools → Recommendations and the auto-apply settings on each campaign.

If recommendations are auto-applied, the bid strategy on a campaign may have changed without your team noticing. The 20-minute audit catches this. Turn off auto-apply for bid-strategy recommendations specifically; they should be a deliberate decision, not a default.

Step 5. Make the switch (or do not)

For each flagged campaign, compare the current strategy with the goal, available signal, controls, and observed results before deciding whether to switch, test, or wait.

There is no universal fallback. Choose bidding controls from the campaign goal, data quality, budget, and observed auction behavior. Manual CPC provides direct bid ceilings, but it still requires active management and may or may not fit the campaign.

After a change, set the evaluation window from the campaign status, conversion cycle, data volume, and volatility. Record the before-and-after evidence before accepting or reversing the strategy.

Decision logic What to do with a flagged campaign.

Limited signal, clean trackingCompare available controls and test the strategy that best fits the campaign goal.

Low volume, broken trackingFix the conversion action before changing the bid strategy. The algorithm cannot optimize against bad signal.

Enough volume, fake valuePause Target ROAS logic until purchase value or margin-adjusted value is reliable.

Enough volume, clean valueKeep the strategy and evaluate structure, landing page, and keyword intent before changing bids.

The mistake to avoid: switching strategies before verifying the signal the strategy is using.

What this audit does not tell you

The 20-minute audit is a stage-fit check, not a full account marketing services. It does not tell you whether your keywords are right, whether your ad copy is converting, whether your landing page is the failure point, whether your conversion tracking is firing accurately, or whether the campaigns are structured correctly to begin with.

If the bid-strategy audit surfaces multiple flagged campaigns, that is usually a downstream signal that the account was set up without a stage-aware strategy in the first place, and the deeper structural issues compound from there. The full audit, the one that produces the prioritized fix list, is what the Conversion Marketing Plan exists to deliver. The 20-minute version is the entry; the 72-hour version is the audit.
