Google Ads gives you roughly half a dozen ways to bid, and choosing the wrong one is one of the most common reasons accounts underperform. The strategies aren't better or worse in the abstract; each fits a specific goal and a specific amount of data. Here's every major bidding strategy, plainly, and when each one actually makes sense.
The two questions that decide your strategy
Before the list, the two things that determine the right choice:
- What's your goal? Clicks, conversions, a cost-per-conversion target, or a revenue/ROAS target.
- How much conversion data do you have? Automated (Smart Bidding) strategies need volume to learn; without it, they guess.
Match the strategy to those two answers and the decision is usually obvious.
The bidding strategies, explained
Manual CPC. You set the maximum bid for each keyword yourself. Maximum control, no automation. Best for brand-new accounts with no conversion data, very low-volume accounts, or situations needing tight per-keyword control. Most accounts outgrow it.
Maximize Clicks. Google gets you the most clicks possible within your budget. Useful early for gathering traffic and data, or for top-of-funnel awareness, but it optimizes for clicks, not outcomes, so it's a stepping stone, not a destination.
Maximize Conversions. Google spends your full budget to get the most conversions it can. A good first Smart Bidding step once you have conversion tracking but no firm cost target yet. Caveat: it will spend the whole budget, so set the budget deliberately.
Target CPA (tCPA). You set the average cost-per-conversion you're willing to pay; Google bids to hit it. The workhorse for lead generation. Needs ~30+ conversions in 30 days to optimize reliably.
Maximize Conversion Value. Like Maximize Conversions, but optimizing for total revenue/value rather than conversion count. For ecommerce or any account with per-conversion values, when you want volume of value without a fixed ROAS target.
Target ROAS (tROAS). You set a return-on-ad-spend goal; Google bids to hit it. The ecommerce standard once you have conversion values flowing. Needs more data than tCPA (~50+ conversions/30 days).
Which one to use
| Your situation | Strategy |
|---|---|
| Brand-new account, no conversions | Manual CPC or Maximize Clicks (gather data) |
| Conversions tracked, no cost target yet | Maximize Conversions |
| Lead-gen with a cost-per-lead target | Target CPA |
| Ecommerce, no fixed ROAS target | Maximize Conversion Value |
| Ecommerce/revenue with a ROAS goal | Target ROAS |
| Very low volume, need control | Manual CPC |
The mistakes that wreck Smart Bidding
- Switching too early. Smart Bidding needs data. Putting a 5-conversion-per-month account on Target ROAS gives the algorithm nothing to learn from.
- Setting an unrealistic target. A Target CPA far below your real CPA makes Smart Bidding bid timidly and starve volume. Start near your actual CPA and move ~10-15% per week.
- Changing strategies constantly. Every change triggers a learning phase (one to two weeks of recalibration). Frequent switching means the account never stabilizes. Pick one, give it two weeks, then judge.
- Optimizing toward bad conversion data. Smart Bidding is only as good as the conversions it learns from. If you count junk form fills, it optimizes for junk. Clean conversion tracking first.
The honest summary
For most lead-gen businesses, the path is: start on Maximize Conversions, accumulate 30+ conversions, graduate to Target CPA, and tune the target gradually. For ecommerce, the same path ends at Target ROAS. The strategy matters far less than matching it to a real goal and feeding it clean data, which is exactly what an account audit checks first.
