If you want to place multiple screeners (Ethnio JS codes) on a page, that's no problem. We've made it so that when ethnio creates a cookie, it prevents users from seeing your screener more than once. Note that this only applies for screeners under the same base domain (acme.com) but NOT subdomains (i.e. apples.ethn.io and oranges.ethn.io). A screener placed on two different subdomains like apples.ethn.io or base domains (like website.com and otherwebsite.com will display once on each website, but this is really rare. Most likely, you have a single domain like hey.com, and you want to place two ethnio JS codes on that page. This totally works.
