### Choose an audience product

Choose the path that matches your available seed.

* **Customer or conversion data:** Build a [Custom AI audiences](/data-and-audience-products/audiences/custom-ai-audiences.md) from CRM lists, site visitors, pixels, or conversion logs.
* **A domain, keyword, product, or existing audience:** Build a [Custom built audiences](/data-and-audience-products/audiences/custom-built-audiences.md).
* **No seed or build time:** Activate a [Pre-built audiences](/data-and-audience-products/audiences/pre-built-audiences.md).

### Choose a specialized audience

Use a purpose-built audience when the campaign depends on a specific channel or intent seed.

* **Search intent:** [Custom search lookalikes](/data-and-audience-products/audiences/custom-search-lookalikes.md) uses search intent as the seed.
* **Retail and CPG:** [Retail purchase intent audiences](/data-and-audience-products/audiences/retail-purchase-intent-audiences.md) uses purchase signals as the seed.
* **CTV:** [CTV-optimized audiences](/data-and-audience-products/audiences/ctv-optimized-audiences.md) provides models built for CTV campaigns.
* **Healthcare and pharma:** [Custom patient targeting](/data-and-audience-products/audiences/custom-patient-targeting.md) uses medical claims or patient-search seeds.

### From seed to activation

Most custom audiences start with a seed. It can include first-party data, a domain, keywords, products, purchase signals, or healthcare signals.

1. **Choose a seed.** Start with the signal that best represents your target customer.
2. **Build the model.** Dstillery identifies similar patterns at scale.
3. **Activate.** Deliver the audience through your buying platform.

Pre-built Audiences skip modeling and activate directly.

### Activate with the right control

Put completed audiences to work through the option that fits your media plan.

* **User segments:** Reach daily refreshed, identity-based audiences.
* **Contextual:** Score inventory in real time, beyond page keywords.
* **Curated deals:** Activate private marketplace packages through SSP partners.
* **Custom bidding algorithms:** Apply model intelligence to bid decisions.
