Let's say a person went to the site from Yandex or Google for the query "business", and then left the site.
How to show ads to him?

Answer 1

Here you have to create a script that determines from the utm tags what request the transition was made on. Then, depending on the request, a user parameter will need to be sent to the counter. And already for this parameter you need to set the goals and conditions of retargeting.
You should start with the help of a programmer for your site, who could create a script to determine the request from the URL and send the parameter/event to Yandex.Metrica/Google Analytics.
