# Audience Boost
## Target high-intent shoppers and increase visibility by applying bid modifiers to specific user audiences.
The **Audience Boost** feature allows you to refine your targeting strategy by focusing on users who are more likely to engage with your brand. By selecting a specific audience, m19 applies a bid modifier to increase your bids for those users, ensuring your ads are more competitive when it matters most.
### **Availability**
This feature is currently available for:
- **Sponsored Products (SP)**
- **Sponsored Brands (SB)**
### **How it works**
When you enable Audience Boost, you are telling the m19 algorithm to aggressively target a specific group of shoppers. The tool applies a **bid modifier**, essentially increasing the bid amount when a user from the selected audience searches for your keywords. This increases the likelihood of your ad being shown to these high-value prospects.
### **Available Audiences**
You can choose from standard Amazon audiences or your own custom audiences.
**1. Standard Amazon Audiences** m19 provides three default audiences based on Amazon's rich shopper data:
- **Purchased brand's product:** Targets shoppers who have previously bought from your brand. Ideal for driving repeat purchases and loyalty.
- **High interest based on shopping history:** Targets shoppers who have shown behavior indicating a strong interest in products similar to yours.
- **Clicked or Added brand's product to cart:** Targets "warm" leads—shoppers who viewed or carted your items but didn't check out. Ideal for remarketing.
**2. Custom AMC Audiences** If you use **Amazon Marketing Cloud (AMC)**, any custom audience you have created there will also automatically appear in the selection list. This allows for highly granular targeting based on your own custom insights.
### **How to enable Audience Boost**
You can configure this feature directly within your Strategy settings.
1. Navigate to the **Strategies** page.
2. Select the strategy you wish to edit.
3. Open the **Advanced Settings** section.
4. Locate the **Boost Audience** option.
5. Click the dropdown menu and select **one** audience from the list.
> **Note:** You can currently select only **one** audience per strategy. If you wish to target a different audience, you must switch the selection or create a separate strategy.
