## What are Social Proof Campaigns?

Social Proof campaigns motivate users to make purchases of a specific product by displaying messages highlighting its popularity.

Such information can be displayed through:

* Labels/badges on the product card
* Pop-up messages in the product card

Social Proof communication can be both general:

* "Popular product"

and detailed:

* "Today, the product was purchased 9 times"

{% hint style="info" %}
The recommended metric for assessing the effectiveness of Social Proof campaigns is the number of product additions to the cart (Add to Cart event).
{% endhint %}

## What Social Proof is Based On

As Social Proof metrics, the following are available:

* The number of product views
* The number of product purchases

This data can be displayed for the following periods:

* 1 day
* 2 days
* 1 week
* 2 weeks
* 1 month

{% hint style="info" %}
Data is collected for complete days based on UTC+3 time zone. For example, when selecting a period of 1 day, data from the entire previous day is used.
{% endhint %}

## Pages Where Social Proof Can Be Implemented

Social Proof can be implemented on any page that features one or more products.
