Is C# namespace should be Project-Name? [closed]

Question

I am working with multiple websites (freelancer) and a good amount of them I write using C# MVC4.

I created a very good boilerplace project that I plan to use on every next starting mvc4 application I build, however the namespace is named Website. I also do a lot of copy-paste from one project to another and then I always have to refactor namespaces, if I will use single namespace (Website) on all my websites then this problem dissapears.

However - will this somehow impact my application, is it considered a very bad practice?
