To direct Ya to do a separate site or on the main to do?

Want to try Direct, to boost sales in our THEM.
In principle, we can make a copy of the main site.
On the copy you can put another phone and then the sales channels will be taken into account separately.

Questions:
1. Whether to make a copy of the site?
2. How not to harm the primary site to not be banned in search? Enough to put on a copy of the site, a ban on indexation robot and code of the website?

Do You even need to make a copy? What prevents to do advertising for the main site?
If you want to track sales channels via phone, you just need to put the call tracking. At least the simplest of Yandex.Call. They are well integrated and nothing to each other does not interfere, does not interfere and indexed in the main search.
