# Use Cases and Examples

> See common ways teams use Provalytics to answer planning, optimization, and measurement questions.

## Overview

## Defending upper-funnel spend

Use:

* [Brand Search Halo](/using-provalytics/brand-search-halo)
* [Halo Effects](/core-concepts/halo-effects)
* [Incrementality Report](/using-provalytics/incrementality-report)

This is useful when leadership sees search capturing demand and asks whether TV, CTV, video, or social should be cut.

## Reallocating budget inside a channel

Use:

* [Campaign Performance](/using-provalytics/campaign-performance)
* [Spend Headroom](/using-provalytics/spend-headroom)
* [Budget Recommendations](/planning/budget-recommendations)

This is useful when the question is not which channel is working, but which campaigns deserve more spend.

## Planning around timing

Use:

* [Opportunity Days](/using-provalytics/opportunity-days)
* [Days to Conversion Report](/using-provalytics/days-to-conversion-report)

This is useful when deciding when to launch, when to push harder, or how soon a channel should be expected to respond.

## Pressure-testing model trust

Use:

* [Proof Report](/using-provalytics/proof-report)
* [Model Validation](/core-concepts/model-validation)

This is useful before taking major planning or optimization actions.
