What is Bid Strategy?
Bid Strategy is your plan for how much you're willing to pay per click or per conversion. A bid strategy doesn't simply mean "I'll set max CPC at 5 euros"—it's a comprehensive strategy for how you optimize your Google Ads budget over time to achieve specific business goals.
While many advertisers bid manually, professional B2B agencies today use automated bidding and smart bidding strategies. These are based on machine learning and automatically adjust bids to achieve maximum efficiency.
The Main Types of Bid Strategies
| Bid Strategy Type | Best For | Focus | Skill Level |
|---|---|---|---|
| Manual CPC | Beginners, small budgets | Maximum control | Low |
| Enhanced CPC (eCPC) | Hybrid approach | Manual + machine learning | Medium |
| Target CPA | Lead generation, fixed budget | Cost per acquisition | Medium-High |
| Target ROAS | E-commerce, known revenue | Return on ad spend | High |
| Maximize Conversions | Volume growth | Conversion volume | Medium |
| Maximize Clicks | Traffic/awareness | Click volume | Low |
| Maximize Value | Multi-tier revenue models | Revenue vs. conversions | High |
Bid Strategy in B2B Context
In B2B, the right bid strategy is critical because:
- A click can cost 10-50 euros (vs. 0.50-2 euros in e-commerce)
- Not all leads are equally valuable (some convert to five-figure deals, others to nothing)
- The sales cycle is long—you often don't know for weeks whether a lead was valuable
- Competition for keywords is intense and can drive up bids
A case study: A B2B company selling "marketing automation software" initially paid 15 euros per click with manual CPC. After switching to target CPA with a 120 euro CPA limit per lead, the cost-per-click dropped to 8 euros, but lead quality increased by 40% because the system bid more intelligently.
Smart Bidding Strategies—The Future
Target CPA (Cost-Per-Acquisition) is often the best choice for B2B. Google's machine learning looks at which keywords, devices, times of day and users lead to conversions, and adjusts bids to hit your CPA goal.
For example: You set target CPA at 150 euros. Google will:
- Bid on keywords that historically lead to conversions
- Bid higher for mobile (if mobile has more conversions)
- Bid lower for generic keywords without conversion history
- Automatically adjust bidding when competition changes
Target ROAS (Return on Ad Spend) is better if you know your revenue per lead. Instead of "I want to pay 150 euros per lead," you say "I want 300% ROAS" (i.e., 3 euros in revenue per 1 euro in ad spend). For B2B with known customer lifetime value, this is optimal.
Maximize Value is new and particularly powerful for B2B with variable deal sizes. Instead of counting conversions, Google considers the actual deal value and optimizes for revenue rather than just conversion volume.
How Do You Choose the Right Bid Strategy?
Phase 1: Is your conversion tracking clean?—Smart bidding doesn't work without good conversion tracking. Test manual CPC or enhanced CPC first until you have 100+ conversions per month.
Phase 2: Are your conversions meaningful?—A "whitepaper download" is not a real conversion. "SQLs" (sales-qualified leads) is better. "Customer" is ideal. The higher your conversion quality, the better smart bidding works.
Phase 3: Choose your KPI—Does a lead cost you an average of 150 euros? Target CPA = 150 euros. Does a customer average 5,000 euros in revenue and you want 3 euros in revenue per ad spend? Target ROAS = 3.
Phase 4: Test and optimize—Start with a strategy. After 4 weeks (at least 50 conversions), analyze whether your CPA goal was met. Adjust accordingly.
Best practices for Bid Strategy Optimization
- Set realistic CPA goals: If your current CPA is 200 euros, Google can't suddenly optimize to 80 euros. Start with minus 10% and increase gradually
- Use campaign-level bidding: Different campaigns have different economics. Enterprise campaign vs. SMB campaign should have different CPA limits
- Use portfolio bid strategies: Google can optimize across multiple campaigns. This is powerful, but use it only when you have traffic
- Consider seasonality: In November everyone wants to advertise, bids increase. Adjust your CPA goal to seasonality
- Build in competitive intelligence: If your competitor bids aggressive CPCs, you need an aggressive bid strategy too
- Understand conversion delay: B2B conversions (e.g., sales calls) often happen 3-7 days after the click. Give smart bidding at least 4 weeks to learn properly
Manual vs. Automated Bidding—When to Use Which?
Choose manual CPC if: You have low traffic (under 100 clicks per month), are testing new keywords, or have very specific control requirements.
Choose automated bidding (target CPA/ROAS) if: You have at least 50 conversions per month, clean conversion tracking, and your business model is stable.
The reality: 80% of successful B2B campaigns use smart bidding. Manual bidding is time-consuming and less effective. If you're not optimizing daily, Google's machine learning will outperform you.
Your bid strategy is not static. Review it monthly, analyze whether your CPA goal is being met, and adjust based on market changes and your business goals.
