Who are arbitrators? What is the essence of their work? What is their difference from directologists, etc.?

Question

contextual advertising

Tell us in detail, so that it would be really clear what their value is, or is it just hype.

Answer 1

An arbitrageur is someone who buys traffic (a flow of people) in one place A (for example, from an advertising network, on a YouTube channel, from other people's doorways, etc.) and sends it to another place B (for someone else's product, service). At the same time, in the process of traveling from A to B, traffic can be filtered, converted, distributed, etc.
The profit of an affiliate is the difference between the funds spent on the purchase of traffic and the funds received from the sale of other people's goods / services.
If it’s quite simple, then this is a specific sales earner. Its value is that by hiring an arbitrator or turning to a cpa network, you are guaranteed to get 1 sale for 1 fixed price. All risks are assumed by the performer.
