Quick answer: A bidding strategy is the rule that determines how much Google Ads pays per click in your campaigns. Choosing the right one has a bigger impact on results than most settings combined: the same campaign can spend the same budget with completely different outcomes depending on whether it is bidding for clicks, conversions, conversion value, or top-of-page position.
What Is a Bidding Strategy?
A bidding strategy in Google Ads defines how your bids are set and optimised. You can control bids manually, let Google automate them towards a specific goal, or use a hybrid approach.
Think of it like driving. Manual bidding is driving yourself, you set every bid. Smart Bidding is cruise control with a destination set, Google manages the speed, but you define where you want to end up.
Main Bidding Strategies
- Manual CPC: You set individual bids for each keyword. Full control, but labour-intensive.
- Enhanced CPC: Manual bids adjusted automatically by Google to improve conversions.
- Target CPA: Google sets bids to get conversions at your target cost per acquisition.
- Target ROAS: Google sets bids to maximise conversion value at a target return on ad spend.
- Maximise Conversions: Google spends your full budget to get as many conversions as possible.
- Maximise Conversion Value: Optimises for total conversion value rather than volume.
- Maximise Clicks: Gets as many clicks as possible within your budget, useful for awareness, not lead generation.
Which Strategy Is Right?
Smart Bidding strategies need conversion data to work well, typically 30+ conversions per month per campaign. Below that threshold, Manual CPC or Maximise Conversions is often more reliable.
Our PPC management service selects and monitors the right bidding strategy for each campaign based on account maturity and conversion volume.
The Main Bidding Strategies in Google Ads
Manual CPC
You set the maximum cost-per-click for each keyword yourself. Maximum control, requires the most management time, and no longer recommended by Google for most use cases. Useful for accounts that need tight cost control on specific terms.
Maximise Clicks
Google automatically sets bids to get as many clicks as possible within your budget. Useful for traffic-driving campaigns or new accounts gathering data. Not appropriate when conversion volume matters more than raw clicks.
Maximise Conversions
Google sets bids to get the most conversions possible within budget. Best for accounts that have at least 30 conversions a month so the algorithm has data to learn from. Less effective in low-volume accounts where the algorithm cannot find a stable pattern.
Target CPA (Cost Per Acquisition)
You tell Google your target cost per conversion, and it bids to hit it. Powerful when you have steady conversion volume and a clear business sense of what a customer is worth. Underperforms when target CPA is set unrealistically low.
Target ROAS (Return on Ad Spend)
Best for ecommerce. You set the return on ad spend you want (e.g. 400 percent), and Google bids to hit it. Requires conversion value tracking, which most ecommerce accounts have, and stable conversion volume.
Maximise Conversion Value
Like Maximise Conversions but optimises for revenue rather than count. Best when individual conversions vary widely in value. Common in ecommerce and lead-gen with different lead types worth different amounts.
How to Choose
The right bidding strategy depends on what you have to work with:
- New campaign, no conversion data: Maximise Clicks for two to four weeks to gather data, then switch.
- Steady conversions, simple goal: Maximise Conversions or Target CPA.
- Ecommerce with stable revenue per click: Target ROAS.
- Brand campaigns with high CTR: Manual CPC if you want to keep CPC very low.
Switch deliberately, not impulsively. Each bidding strategy needs at least two to four weeks to stabilise before you can fairly evaluate it.
Frequently Asked Questions
Should I use manual or automated bidding?
For most accounts in 2026, automated bidding is now the default. Google’s Smart Bidding has improved enough that manual CPC is rarely the best choice. The exceptions are accounts with very low conversion volume, where Smart Bidding lacks data, or specialist cases where you need precise control over individual keyword spend.
How long does Smart Bidding take to learn?
About two to four weeks once you switch to a new strategy. During this period, performance can swing both ways as the algorithm explores. Avoid changing budgets, targeting, or settings during the learning period unless something is clearly broken.
Can I have different bidding strategies in the same account?
Yes. Each campaign has its own bidding strategy, so a brand campaign can use Manual CPC while an acquisition campaign uses Target CPA. This is recommended for most accounts because different campaign goals genuinely call for different strategies.
What is the best bidding strategy for small budgets?
Manual CPC or Maximise Clicks, depending on whether you want control or simplicity. Smart Bidding strategies struggle with small budgets because they need conversion volume to learn. Once you consistently get 30+ conversions a month, switching to Maximise Conversions usually outperforms manual.
