# Glossary

A quick guide to the words you'll see across Frak. Most of them describe everyday ideas: a store, a customer who shares, the friend who buys.

## Merchant

Your store on Frak: a website or domain where you run campaigns. You can manage several merchants from one account. [Register your site](/guides/dashboard/register/).

## Ambassador

A customer who shares your store with friends. When their share leads to a sale (or another action you chose), they earn a reward. Ambassadors are sometimes called referrers.

## Referee

The friend who arrives through an ambassador's link and buys. Referees can earn a reward too, which is a great reason to click.

## Campaign

A set of rules for what customers earn and what triggers it. You choose a goal (sales, traffic, or registrations), a budget, and the rewards. [Create a campaign](/guides/campaigns/create/).

## Reward budget

The pot your campaigns pay rewards from. You top it up by card, and Frak only spends it on real, confirmed actions. [Add funds](/guides/dashboard/configure/funds/).

## Reward model

How a reward is calculated: a **fixed amount**, a **percentage of the basket**, or **tiered** (bigger baskets earn more). You set this when you create a campaign.

## CPA (cost per action)

What you pay for one confirmed result, like a sale. Frak shows your average CPA so you can see your real cost, and how it compares to paid ads.

## Members

The customers who joined by sharing your store. You can filter them into groups and reach out. [Send push notifications](/guides/campaigns/push/).

## Push notification

A short message you can send to your members' phones, for example to announce a new campaign or product.

## Explorer

A directory in the Frak app where users discover stores worth sharing. Listing your brand there is optional. [Customize how you appear](/guides/dashboard/configure/explorer/).

## Wallet

A free Frak account, secured by fingerprint or face unlock instead of a password. You use one to manage your store, and your customers use one to collect their rewards.

## Domain verification

A one-time check that proves a domain is yours, done by adding a small DNS record. It's part of registering your site. [How it works](/guides/dashboard/register/).
