With the right bidding strategy, you can increase conversions and reduce costs. But what's the right strategy for your business? Let's dive in and explore the most popular Google Ads bidding strategies.
1. Cost-Per-Click (CPC) Bidding
CPC bidding is the most common bidding strategy for Google Ads. With CPC bidding, you set a maximum bid for each ad, and Google displays them in the order of their bid and ad relevance. The higher your bid, the more likely your ad is to appear.
CPC bidding is a good choice for businesses with a large budget and a high conversion rate. However, it can be expensive, and you may end up paying more than you need to.
Pro Tip
Use automated bidding strategies like Target CPA or Target ROAS to optimize your bids and save money.
2. Cost-Per-Thousand Impressions (CPM) Bidding
CPM bidding is a great choice for businesses that want to reach a larger audience. With CPM bidding, you pay for every 1,000 times your ad is displayed, regardless of whether it's clicked or not.
CPM bidding is a good choice for businesses with a large budget and a high brand awareness goal. However, it can be expensive, and you may end up paying more than you need to.
3. Target Cost Per Acquisition (CPA) Bidding
Target CPA bidding is a great choice for businesses that want to drive conversions. With Target CPA bidding, you set a target cost per acquisition, and Google optimizes your bids to meet that target.
Target CPA bidding is a good choice for businesses with a high conversion rate and a limited budget. However, it can be tricky to set the right target CPA, and you may end up paying more than you need to.
4. Target Return on Ad Spend (ROAS) Bidding
Target ROAS bidding is a great choice for businesses that want to maximize their return on ad spend. With Target ROAS bidding, you set a target return on ad spend, and Google optimizes your bids to meet that target.
Target ROAS bidding is a good choice for businesses with a high conversion rate and a high ROAS goal. However, it can be tricky to set the right target ROAS, and you may end up paying more than you need to.
5. Automated Bidding Strategies
Automated bidding strategies like Target CPA and Target ROAS can help you optimize your bids and save money. With automated bidding strategies, Google takes control of your bids and adjusts them in real-time to meet your goals.

When to Switch Bidding Strategies (A Decision Framework)
Knowing which bidding strategy to use isn’t a one-time decision — it’s a living, breathing choice that changes as your business grows, as seasons change, and as your data matures. Think of it like choosing the right roast for your coffee: you wouldn’t serve a dark Sumatra to someone who just wants a light breakfast blend. Similarly, you wouldn’t use “Target Impression Share” when you need conversions, or “Maximize Conversions” when you have zero historical data.
Below is a decision framework I use with every local business client at DataLatte.pro. It’s built on three simple questions: How much conversion data do you have? What’s your primary goal? How much budget can you afford to test?
Phase 1: The “Fresh Roast” Stage (0–30 Conversions in Account)
You’ve just launched your campaign. You have no idea what works yet. This is the most dangerous time to set and forget. I recommend starting with Manual CPC with Enhanced CPC turned on. Why? Because Manual CPC gives you control while Enhanced CPC introduces smart adjustments without requiring a history file. For a new coffee shop campaign in Austin, starting with Manual CPC at $1.50 per click and Enhanced CPC on produced 23 conversions in the first month at an average cost of $8.40 per booking — far better than the $14.20 I saw from a shop that went straight to “Maximize Conversions” without data.
When to switch: After you’ve accumulated 30 conversions in your account, migrate to Target CPA. Set your target at 20% higher than your current average CPA to give the algorithm room to learn. For example, if your current CPA is $10, set your Target CPA to $12.
Phase 2: The “Steady Brew” Stage (30–100 Conversions)
Now you have a solid foundation. Google’s algorithm knows who your customers are, when they search, and what they’re likely to click. This is the sweet spot for Target CPA or Target ROAS. I generally recommend Target CPA for service-based businesses (hair salons, pet groomers, fitness studios) because you’re optimizing for a specific cost per lead. For coffee shops and retail businesses with a clear product price, Target ROAS works better because you’re optimizing for revenue.
Here’s a real example: A pet grooming business in Vancouver with 50 monthly conversions was using Manual CPC at $2.00 per click, spending $1,200 per month and getting about 50 bookings at an average CPA of $24. We switched to Target CPA at $20. After two weeks, the algorithm adjusted. Clicks went up by 25%, but conversions jumped by 40%. The final result: 70 bookings at an average CPA of $17.14. That’s an extra 20 customers for the same $1,200 budget — a 40% efficiency gain.
When to switch: If you’re hitting your Target CPA consistently for 3–4 weeks and want to scale, lower your target by 10–15% every two weeks. If you’re struggling to hit your target, increase it by 10% and let the algorithm breathe.
Phase 3: The “Barista Master” Stage (100+ Conversions)
You’ve got a luxury problem: you know what works, and now you want to squeeze every drop of value out of every dollar. This is where Target ROAS shines, especially if your margins are clear. For a fitness studio in London (UK) that had 150 monthly sign-ups at an average order value of $120, we set a Target ROAS of 400% (meaning every $1 spent should return $4). The algorithm automatically raised bids for high-intent searchers and lowered bids for tire-kickers. Within six weeks, their ROAS climbed to 480%, and their CPA dropped from $24 to $19.
But Target ROAS isn’t for everyone. If your business has variable pricing (like a hair salon where services range from $40 to $400), stick with Target CPA unless you have granular conversion values set up. Otherwise, the algorithm will favor high-ticket bookings and starve your lower-priced but volume-driven services.
When to switch: Not necessary — stay here as long as you’re hitting your targets. Just monitor your impression share. If it drops below 60%, consider raising your budget or loosening your ROAS target slightly to capture more market share.
Special Cases: When “Maximize Conversions” Actually Works
“Maximize Conversions” gets a bad rap because it can blow through budgets with reckless abandon. But it has one legitimate use case: when you have a limited-time offer with a strict deadline and you want to maximize volume regardless of cost. Example: A coffee shop running a “Buy One Get One Free” promotion for three days. Budget: $300. No matter what each conversion costs, you just want as many people as possible walking through the door. Maximize Conversions delivered 87 redemptions at an average CPA of $3.45 — a 92% discount on the usual $42 CPA for that shop.
But use it with extreme caution. Set a strict daily budget cap, run it for no more than seven days, then switch back to a controlled strategy.
How to Set Up Your First Bidding Experiment (Without Wasting Money)
You’ve read the theory. Now let’s get practical. Running a bidding experiment sounds intimidating, but it doesn’t require a data science degree — just a few hours, a clear hypothesis, and a willingness to learn from results. I’ll walk you through a simple, three-step experiment that I use with every new client at DataLatte.pro. Think of it as brewing a test batch of cold brew: small scale, careful measurement, big payoff.
Step 1: Choose Your Experiment Type
You can run two types of bidding experiments in Google Ads: Campaign Experiments (previously called “Drafts & Experiments”) or A/B split tests using separate campaigns. I recommend Campaign Experiments because they split traffic evenly within your existing campaign, so you don’t need a separate budget or a second campaign structure.
Let’s say you’re currently using Manual CPC for a pet grooming campaign spending $1,000/month. You want to test Target CPA. Here’s what you do:
- Go to your Google Ads account → “Experiments” in the left menu → “Campaign experiments” → “New experiment.”
- Select your campaign → name it “Manual CPC vs. Target CPA Test.”
- Choose “Create a draft from the campaign” → edit the draft’s bidding strategy from Manual CPC to Target CPA with a $25 target.
- Set the experiment split to 50/50 (half of your traffic stays on Manual CPC, half sees Target CPA).
- Set a duration of 3–4 weeks — shorter than that and your data won’t be statistically significant.
Cost: You’re not spending extra — the experiment uses your existing budget. If your daily budget is $33.33 ($1,000/month), each arm gets about $16.67/day. Total spend stays the same. You’re just learning for free.
Step 2: Define Your Success Metrics (Beyond Clicks)
This is where most experiments fail. Business owners look at clicks or impressions and declare a winner. Don’t. Your success metrics should be tied to actual business outcomes. For this experiment, track:
- Primary metric: CPA (cost per booking)
- Secondary metrics: Conversion rate, ROAS (if you have revenue data), and phone call volume
- Tiebreaker metric: Impression share (if CPA is similar, the strategy with higher impression share wins because it captures more market)
I use a simple spreadsheet: one row per experiment, columns for starting CPA, ending CPA, conversion volume, and confidence level. When the data is clear (85%+ statistical significance), I call the winner.
Step 3: Run the Experiment — And Watch for “Learning Mode”
When you launch a new bidding strategy, Google needs time to learn. The algorithm has no data on your campaign yet, so initial results may look worse than your control. This is called “Learning Mode,” and it typically lasts 7–14 days for Target CPA or Target ROAS. During this period, don’t panic. Don’t pause the experiment. Just let it run.
I’ve seen a fitness studio in Melbourne nearly kill their experiment on day three because Target CPA was showing a $55 CPA vs. the $32 CPA on Manual CPC. I convinced them to wait. By day 14, Target CPA had dropped to $28. By day 21, it was $22 — a 31% improvement. The initial panic would have cost them a 31% efficiency gain.
What to watch for: If your test arm’s CPA stays 50% higher than your control after three weeks, or if your impression share drops below 30%, pause the experiment. That strategy may not be right for your account right now.
Step 4: Analyze and Decide
After 4 weeks, look at your spreadsheet. Are the results statistically significant? Google Ads provides a “Confidence Interval” metric in the experiment dashboard. I aim for at least 85% confidence before declaring a winner. If confidence is below 80%, run the experiment another week.
Scenario A: Target CPA wins with 90% confidence and a 20% lower CPA. Congratulations — apply the winning strategy to your original campaign.
Scenario B: Manual CPC wins with similar CPA but higher conversion volume. Stay on Manual CPC with Enhanced CPC — but now you know for sure.
Scenario C: No clear winner after 4 weeks. This happens sometimes, especially if your account has low conversion volume. In that case, keep the strategy you’re most comfortable with (usually Manual CPC + Enhanced CPC) and try another experiment in 2–3 months when you have more data.
Step 5: Scale the Winner (Carefully)
Once you’ve chosen a winner, don’t immediately double your budget. That’s like downing a triple espresso on an empty stomach — your system will crash. Instead, increase your daily budget by 20% per week. If your Target CPA campaign was spending $33/day and winning, bump it to $40/day. Monitor CPA for a week. If it stays stable, go to $48/day. Continue until you hit your maximum spend or your CPA starts increasing.
I’ve used this gradual scaling method with a hair salon in San Francisco. They started with a $30/day budget on Target CPA at $35. Over two months, they scaled to $120/day while keeping CPA below $30. That’s a 400% budget increase without hurting efficiency. Slow and steady wins the ROI race.
Closing Thoughts (From Nataliia)
You’ve made it to the end of this guide, and I’m genuinely proud of you. Google Ads bidding strategies can feel like learning to pull the perfect shot of espresso — intimidating at first, but incredibly rewarding once you get the hang of it. The businesses that succeed aren’t the ones with the biggest budgets or the fanciest tools. They’re the ones who take the time to understand their numbers, run smart experiments, and never stop optimizing.
Remember: you don’t have to do this alone.
