# How to Enable the Google Ads Upstack Purchase Goal and Switch to Primary Optimization Goal
> Promote the Upstack Data purchase goal from secondary to primary in Google Ads after 4–7 days of data — switching optimization to server-side conversions for better Smart Bidding performance.
**Quick Summary**
* Wait 4–7 days after creating the **"Purchase - UpstackData"** goal so Google can collect baseline data.
* In Google Ads, navigate to **Goals → Summary** and click **Edit goals**.
* Open the **Conversion action optimization** section.
* Set **"Purchase - UpstackData"** as **Primary** and switch all other Purchase goals to **Secondary**.
* Click **Save**.
## Prerequisites
Before you start, you need:
* **Admin** or **Manager** access to the **Google Ads** account
* The **"Purchase - UpstackData"** conversion already created and live for **4–7 days** (see [How to Create a New Upstack Data Purchase Goal in Google Ads →](/guides/google-ads/how-to-create-a-new-upstack-data-purchase-goal-in-google-ads))
## Importance of this Step
When creating the **"Purchase - UpstackData"** goal in Google Ads, we initially set it as **Secondary** for observation only. This allows Google to collect baseline data without disrupting current optimization. After 4–7 days, switching to **Primary** activates the goal as the optimization target with sufficient data.
## Steps to Switch Your Purchase Goal
Sign in to [Google Ads](https://ads.google.com).
In the left-hand menu, navigate to **Goals → Summary**.
On the Goals Summary page, scroll down to the **Purchase** conversion list.
Click **Edit goals** to open the goal settings panel.
Click **"Conversion action optimization"** to expand the section.
Set **"Purchase - UpstackData"** as **Primary**.
Set all other Purchase goals to **Secondary**.
Ensure only **one Primary** Purchase conversion goal is active at a time.
`Example: Purchase - UpstackData is Primary and other Purchase conversions are Secondary`
Click **Save** to apply the new settings.
## Verify the Setup
To confirm the switch was applied:
* Return to **Goals → Summary** in Google Ads — **"Purchase - UpstackData"** should be labelled **Primary** and all other Purchase goals should be labelled **Secondary**.
* Open one of your active Search or Performance Max campaigns and confirm it is optimizing against the new Primary goal.
If the goal still appears as Secondary, refresh the page and re-open **Edit goals** to confirm the change saved. If issues persist, contact Upstack Data support.
