What is the difference between YAN and Direct?

Question

Yandex

Yandex has YAN and Direct. What is the difference between them? How to get started with them? Is IP registration required?

Answer 1

Ads in YAN advertising networks and in search are broadcast according to different principles:
In search, the user enters a keyword and receives a response relevant to his request. I was looking for plastic windows - I got plastic windows.
In networks, advertising is part of the content of the page and is shown depending on:
topics (the content of the page corresponds to the content of the ad);
previously entered user requests (behavioral targeting);
previously visited sites (retargeting).
IP is unnecessary
