Bidding strategies in Google Ads: A practical guide

Author:

The bidding strategy in Google Ads determines which searches your ads will appear for, based on your traffic objective.


Depending on your strategy, Google will show your ads in some searches and not in others — especially if your budget is limited. Choosing the best bidding strategy in each case is key to maximizing your available budget.
Each campaign can use a different strategy, and you can also apply portfolio bidding strategies for campaigns with shared goals.

Two main types of bidding strategies:

a) Manual Bidding (Manual CPC)

💡 You decide the maximum amount you're willing to pay per click.
✔️ Gives you more control.
⚠️ Requires time and expertise from the account manager.
❌ Misses out on Google’s machine learning optimization.

b) Automated Bidding (Smart Bidding)

🤖 Google adjusts bids in real-time using data and your campaign objectives.
This approach increases overall efficiency, although you lose control over the exact CPC. The goal is to optimize total account profitability.

Types of Automated Bidding by Objective:

👁️ If you focus on visibility:

➡️ Target Impression Share – Your ad appears as frequently as possible. Ideal for brand awareness. It’s the least commonly used strategy.

👣 If your goal is to drive website traffic:


➡️ Maximize Clicks – Gets the most clicks possible within your budget. Useful when launching a new account or when there’s little conversion data.

💰 If you're focused on conversions:


➡️ Maximize Conversions – Attracts more qualified users. CPC may be higher, but conversion rate typically improves.
➡️ Target ROAS – Set a desired return on ad spend. 🔝 Great for eCommerce.
➡️ Target CPA – Get conversions at your desired cost per acquisition.
➡️ Maximize Conversion Value – Ideal if conversion value varies and you want to fully use your budget.

Portfolio bid strategy:

Perfect for large accounts with similar campaigns (e.g. international eCommerce). These strategies use AI to optimize several campaigns together.
Commonly used when there’s CPC inconsistency without conversion improvements.

Final Tip:

Track your conversions carefully and assign value to them. Smart Bidding's effectiveness depends on the quality of the data you give Google. Monitor performance regularly and consider adjusting your ROAS or CPA targets based on the metrics you see.
