No you licence a "page" to use it. A "web application" is not covered by the licence. The single website licence is nearly useless:
> For use on a simple webpage that is not considered a web application. A web application is a website that has customer specific data or charges for its use. This requires a Developer license.
You either license a site to use it, license a team of app developers to use it in however many sites you like, or buy an OEM to ship it.
