How to exclude those who have already visited the site with Yandex.Direct?

Question

contextual advertising

Good afternoon, you need to exclude those who have already visited the site, completed the target action for a period of 30 days. source Yandex.Direct.
I excluded:
1. standard segment failures -100%
2. metric target who left the request -100
3. metric segment who left the request and performed the target action after the request +30%

Tell me how to solve the first question.
2 question "Is item 3 set correctly so that Yandex selects and shows ads with increased adjustment, to those who are more similar in behavior, to those who left the application and performed the target action after the application.
Thank you in advance. I will not remain in debt

Answer 1

You set adjustments for those who have already interacted with your site. Also in point 3. It's not "similar to...". To create a Look-alike audience, use the Yandex audience tool . There, on the created segments, you can separately create audiences "similar to ...".
