Your bidding strategy is the engine that drives your Google Ads performance. Choose the wrong one, and even perfectly crafted ads with ideal targeting will underperform. Choose the right one, and you’ll unlock the full potential of Google’s AI to find the most valuable clicks at the lowest cost.
After managing over ₹50 lakh in monthly Google Ads spend, Balistro’s team has tested every bidding strategy extensively across D2C e-commerce, B2B lead generation, and local service businesses. Here are all 8 Google Ads bidding strategies ranked by real-world performance, with clear guidance on when to use each one.
1. Target ROAS (tROAS) — Best Overall for E-commerce
Performance Rating: ★★★★★ | Best for: E-commerce with 30+ monthly conversions
How it works: You set a target return on ad spend (e.g., 400%), and Google’s AI automatically adjusts bids in each auction to achieve that target. It uses real-time signals including device, location, time of day, audience, and search query to predict conversion value and bid accordingly.
When to use: When you have at least 30 conversions per month with varying order values. Target ROAS is the gold standard for e-commerce because it optimizes for revenue, not just conversion count. Brands using tROAS typically see 15-25% improvement in ROAS compared to manual bidding.
Warning: Setting your target too aggressively (too high) will restrict volume. Start 10-20% below your actual ROAS and gradually tighten as the algorithm learns.
2. Maximize Conversion Value — Best for Scaling Revenue
Performance Rating: ★★★★★ | Best for: E-commerce brands focused on top-line revenue growth
How it works: Google spends your entire daily budget to generate the maximum total conversion value (revenue). No ROAS target constrains the algorithm — it simply maximizes revenue within your budget.
When to use: When scaling is your priority over efficiency. Maximize Conversion Value paired with a budget cap is excellent for discovering new profitable audience segments that tROAS might miss due to its efficiency constraints. Use this when you have a clear daily budget and want Google to find every possible dollar of revenue within it.
Pro tip: Use Conversion Value Rules to adjust values by audience segment, ensuring the algorithm prioritizes high-LTV customers.
3. Target CPA (tCPA) — Best for Lead Generation
Performance Rating: ★★★★☆ | Best for: B2B lead generation, SaaS, service businesses
How it works: You set a target cost per acquisition, and Google adjusts bids to hit that target on average. The algorithm may bid higher for searches more likely to convert and lower for less likely ones.
When to use: When all conversions have roughly equal value (like form submissions or phone calls). Target CPA is the go-to strategy for B2B brands because lead values are often uniform. Requires at least 30 conversions per month for reliable optimization. Brands switching from manual CPC to Target CPA typically see 20-30% reduction in CPA within 60 days.
Warning: Don’t set target CPA below your actual CPA — start at your current CPA and reduce by 10-15% as performance improves.
4. Maximize Conversions — Best for New Campaigns
Performance Rating: ★★★★☆ | Best for: New campaigns needing conversion data quickly
How it works: Google spends your daily budget to generate the maximum number of conversions, regardless of cost per conversion. The algorithm learns which clicks are most likely to convert and prioritizes those.
When to use: When launching new campaigns that don’t yet have 30+ conversions per month. Maximize Conversions gathers data fast, building the conversion history needed to switch to more sophisticated strategies like tCPA or tROAS later. Also useful for campaigns with strict daily budgets where you want every rupee working toward conversions.
Transition plan: Run Maximize Conversions for 4-6 weeks to build data, then switch to Target CPA or Target ROAS once you have 30+ monthly conversions.
5. Enhanced CPC (eCPC) — Best Hybrid Approach
Performance Rating: ★★★☆☆ | Best for: Advertisers who want some automation but not full control surrender
How it works: You set manual bids for each keyword, and Google can adjust them up or down (by up to 100%) based on the likelihood of conversion. It’s a middle ground between manual and fully automated bidding.
When to use: When you have specific keywords where you know the ideal bid but want Google to make micro-adjustments. eCPC works well for accounts with low conversion volume (under 30/month) where Smart Bidding strategies don’t have enough data. It’s also useful for highly competitive keywords where you want to maintain a bid floor while allowing upward flexibility.
Note: Google has been de-emphasizing eCPC in favor of fully automated strategies. It’s being phased out for Shopping campaigns.
6. Manual CPC — Best for Testing and Control
Performance Rating: ★★★☆☆ | Best for: Small budgets, new accounts, granular control needs
How it works: You set exact maximum bids for each keyword. Google never exceeds your bid. You have complete control over spending at the keyword level.
When to use: When starting with very small budgets (under ₹15,000/month), when testing new keywords where you don’t want unpredictable spending, or when you need absolute cost control for specific high-competition terms. Manual CPC is also useful for brand campaigns where you want to ensure you always appear at position 1 for your brand name at a controlled cost.
Downside: You miss Google’s real-time auction signals. Manual bidding is like driving with your eyes on the road but not using GPS — you can get there, but the automated route is usually faster.
7. Maximize Clicks — Best for Traffic Goals Only
Performance Rating: ★★☆☆☆ | Best for: Brand awareness, content promotion, gathering initial data
How it works: Google automatically sets bids to get the most clicks within your daily budget. You can set a maximum CPC bid cap to control costs.
When to use: Only when your goal is traffic volume (not conversions). Useful for brand awareness campaigns, content marketing promotion, or gathering initial traffic data for a new website. Always set a CPC bid cap to prevent overpaying for low-value clicks.
Warning: Maximize Clicks optimizes for click quantity, not quality. The traffic it generates often has lower conversion rates than intent-optimized strategies. Do not use for campaigns with conversion goals.
8. Portfolio Bidding — Best for Account-Level Optimization
Performance Rating: ★★★★☆ | Best for: Large accounts with multiple campaigns sharing goals
How it works: Portfolio bid strategies apply a single bidding strategy across multiple campaigns, allowing Google to balance performance across them. If one campaign is over-performing, the algorithm can shift budget and bids to help under-performing campaigns catch up.
When to use: When you have 5+ campaigns targeting similar goals (e.g., all aiming for ₹500 CPA). Portfolio strategies are especially powerful for accounts with campaigns that individually have low conversion volume but collectively hit the 30+ threshold. This gives Smart Bidding the data it needs to optimize effectively across the whole account.
