Since this link is not your own local link, under the same domain, you would require to use the protocol with it as well. Try using this,
var url = "http://www.ggg.com";
<a href="@url">Awesome Domain</a>
The type of variable doesn't matter — static variable like var url or string[] list — what matters is what gets loaded there. So, just a tip trick,
1. Use http protocol for external URLs.
2. You can use "~" for local paths as well.
3. Follow a standard of URLs, that helps creating hyperlinks for internal files and external files; using http, vs local physical path etc.
