# ASP.NET MVC: Defining short URL-s for root level pages

Short URL-s are more and more important part of page usability as mobile internet is growing. Long URL-s are not convenient to type due to small keyboards and screens of mobile devices. Also short URL-s are easier to remember and using well chosen short URL-s your pages may also get better rankings in search engines indexes. In this posting I will show you how to create short URL-s for ASP.NET MVC pages.

### Default routes

Routes used by default are part of ASP.NET MVC applications right from start. After creating new ASP.NET MVC application you can find the following RegisterRoutes() method from Global.asax file.

public static void RegisterRoutes(RouteCollection routes){    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");     routes.MapRoute(        "Default", // Route name        "{controller}/{action}/{id}", // URL with parameters        new        {            controller = "Home",            action = "Index",            id = UrlParameter.Optional        } // Parameter defaults    );}

IgnoreRoute() call here sais to ASP.NET MVC that *.axd files need no processing. Call of MapRoute() method creates new route and sets the following default values:

• controller – if controller name cannot be found from URL then take HomeController,
• action – if action cannot be found from URL then take Index() as default action,
• id – it is optional and may be omitted.

We can define other routes too if we need.

### Shortening URL of About page

As all ASP.NET MVC applications get by default also page called default we can use it to analyze its default URL and create shorter URL after that. By default, About page has the following URL:

As Home controller is all about “default” pages as activities that happen on root level of site we don’t have any good reason to keep word Home in URL. In SEO terms it increases the distance of page title and in some cases shorter URL-s perform better in search engines.

To get short URL like this:

add the following route definition to previously shown method, right before last route definition.

routes.MapRoute(    "ShortAbout",    "about",    new { controller = "Home", action="about" });

When you run your application you can see that ASP.NET MVC generates short URL for About page automatically.

This solution works well if you have only some pages under root level of site. This is default case for many pages. Of course, it is possible to write more code and have more advanced routing that handles all short URL cases but right now I think this way you move quicker.

### Conclusion

ASP.NET offers powerful routing mechanism and MVC framework makes good use of it. Sometimes we may need better URL-s for root level pages than the ones that are generated by MVC framework by default. There may be pages like About, Terms, Join, Log in etc. If we don’t have many pages on root level we can easily define new routes for these pages that offer shorter URL-s that are easier to remember and easier to type on mobile devices. Also search engines may give better rankings to our pages if we don’t use longer URL-s. We saw that it was easy to add new routes to routes collection for pages that need shorter URL. Our method works as far as there are not much pages on root level of site.
