Yes. You can create and manage campaigns for multiple sites using our "Site Manager" tool or just install the same tracking code on multiple sites. To find your "Site Manager", log into your account, click your name at the top right and select "Your Sites." Every new site you create gets its own tag, dashboard, ad manager etc. If you choose to just use the same tracking tag on multiple sites, you'll be limited in terms of creating precise retargeting lists, but the code will still work!
