A conversion action is a specific customer action that Google Ads counts as a conversion, such as a purchase, a lead form submission, or a phone call. Each action has its own value, counting method, conversion window, attribution model, and a primary or secondary goal setting.
Key Takeaways
- An account can track many conversion actions; each is configured separately
- Primary actions feed bidding and the Conversions column; secondary actions only appear in reports
- Counting can be “Every” (each purchase) or “One” (one lead per click)
- Value can be fixed, dynamic (the order amount), or none
- A wrong setting on one action can redirect Smart Bidding without any visible error
What Is a Conversion Action
Conversion tracking is the system; a conversion action is one thing that system counts. An e-commerce store might track purchases, add-to-cart events, and newsletter signups as three separate actions. A service business might track form submissions and calls from ads.
How It Works
Each conversion action has these settings:
| Setting | What it controls |
|---|---|
| Goal and action optimization | Primary (used for bidding) or secondary (observation only) |
| Value | Fixed value, a value passed with each conversion, or no value |
| Count | Every conversion, or one per click |
| Click-through window | How long after a click a conversion is still credited |
| Attribution model | How credit is shared across ad clicks on the path |
The data arrives from the Google tag, Google Tag Manager, a Google Analytics 4 import, call tracking, or an offline upload.
Practical Example
A store tracks “Purchase” with dynamic value and “Add to cart” with a fixed value of 1, both as primary. Reported conversion value now mixes revenue with cart additions, and ROAS looks better than reality. Moving “Add to cart” to secondary keeps it visible in reports while removing it from bidding and from the ROAS figure.
Why It Matters
Conversion actions define what “working” means for the account. Every automated strategy, every CPA and ROAS number, and most reporting depend on which actions are primary and how they are counted. Reviewing them is one of the first checks on any account.
