How do I optimize Google Ads campaigns for better conversions?

If the ultimate objective is conversions—whether it's through purchases, sign-ups, or leads—automated bidding strategies such as Target CPA, Maximize Conversions, and Target ROAS are your top choices. These options apply machine learning from Google to maximize your bids in real time, taking into account historical conversion rates, user behavior, and context signals such as device, location, and time. Target CPA (Cost Per Acquisition) is great when you have a specific cost per conversion goal. It balances volume and efficiency by bidding higher on users who will likely convert at your target cost. Maximize Conversions takes this even further, demanding the highest volume of conversions that your budget allows—works great for aggressive growth campaigns, but can increase CPA over time. Target ROAS is best for eCommerce brands and maximizes not only conversions but also value per dollar.
