Niches: white, black, and gray

To put it simply, white arbitration is transparent work without cheating. Black arbitration is a deception of all participants in the business. Arbitrator cheats customers, advertisers, and affiliates. The niche determines the work approach and the product of a particular advertiser. Almost all popular verticals are gray. Therefore, they can be divided into gray and relatively black.

The gray verticals include:

Nutra. Products for youth and beauty (weight loss, rejuvenation and other ailments);
Gambling and betting. Betting is legal in many countries, and casinos only in some. Many networks allow them to be advertised, though they are banned from demanding traffic sources.
Sweepstakes. The user is asked to participate in a drawing for a phone, more rarely a comp or other valuable prize. In return, they ask for contact information, and less frequently – entry of their card data or a small payment for participation;

Black verticals include:

Adult. These are merchandise and subscriptions for access to exclusive adult videos, as well as dating, porn, and webcam. Technically, it’s more like a gray vertical. But in fact, there are far more restrictions for adult topics than there are for nutra or gambling;
Scam. Scam offers are most common among trading and crypto. On the face of it, it is a platform for asset trading. But, once the finances are deposited on this platform, the user can no longer withdraw them from it, even after successful trades. Also, such offers are disguised as casinos and betting offices. If it is possible to withdraw the won money from the official casino’s account, then the scam office simply takes all the players’ deposits. Another option – the sale of useless courses, when paying for the purchase, the user does not get anything

Be careful when choosing, because you risk not only the money, but also your reputation.
