Quick Definition #
PPC bidding strategies determine how bids are set to compete for ad opportunities. Google Ads offers manual and automated approaches; the suitable option depends on the campaign goal, data quality and level of control needed.
Common Strategy Types #
- Manual CPC: The advertiser sets bids at supported levels, retaining direct control over bids.
- Maximize Clicks: Automated bidding aims to obtain clicks within the configured budget and limits.
- Maximize Conversions: Aims to obtain as many tracked conversions as possible within the budget.
- Target CPA: Aims to generate conversions around a chosen average cost per acquisition, where supported and suitable.
- Maximize Conversion Value: Aims to obtain conversion value within the budget.
- Target ROAS: Aims to achieve a selected conversion-value-to-ad-spend ratio, where supported and appropriate.
- Target Impression Share: Aims for a chosen level of search impression visibility within its settings.
Names, availability and controls can change by campaign type. Check current Google Ads options before implementation.
How to Choose #
- Define the primary objective and success metric.
- Ensure conversion tracking measures meaningful actions accurately.
- Assess whether enough reliable data exists for automated conversion-based bidding.
- Set a realistic budget and any suitable bid limits or targets.
- Allow a reasonable learning period and avoid frequent disruptive changes.
- Evaluate results by conversion quality and value, not only click volume.
Example #
A campaign designed to generate qualified enquiries may test conversion-focused bidding after its form submissions and lead quality are tracked reliably. A new campaign without meaningful conversion data may need a cautious initial approach and close monitoring.
Important Trade-Offs #
More automation can use auction-time signals but reduces direct control over each individual bid. A target set too aggressively may restrict delivery; a target set too loosely may spend budget without achieving the desired efficiency. Results are not guaranteed.
Common Mistakes #
- Choosing a bidding strategy before defining the goal.
- Optimising toward inaccurate or low-value conversion actions.
- Setting unrealistic CPA or ROAS targets.
- Changing strategy and budget repeatedly during learning.
- Comparing campaigns without accounting for differences in intent or conversion value.
Key Takeaway #
Match the bidding strategy to the business objective and the quality of measurement. Reliable conversion data is essential for meaningful automated optimisation.
