Yottaa uses domain names to organize site optimizations and determine which traffic to optimize. When you add a site to Yottaa, we will only optimize the assets that are loaded from that particular domain. In nearly all cases, your site well load resources from a range of domain names (referred to as "other" or "resource" domains), some that you control and others that you don't.
It is recommended that you add as many domain names as possible so that Optimizer can optimize more resources for you. Our Professional Services team is here to help if you require assistance maximizing the impact Yottaa has on your site.
