SEO Friendly MVC routing

            

              Normal routing in asp.net mvc is not much SEO friendly. Commonly we are using {controller}/{action}/id route by default.

  Default routing:
                   routes.MapRoute(

                "Default", // Route name
                "{controller}/{action}/{id}", // URL with parameters
                new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
            );

normally we are using an integer number in the place of id (usually database table keys). Urls like this is not SEO friendly ( eg:    www.yourdomain.com/Location/details/2). If  we can build a url with string which is the name of the particular item( eg: location,book,movie etc). it will become more SEO friendly. Such as www.yourdomain.com/Location/details/Location name.
      This is possible in asp.net mvc by adding one more route in Global.asax. Note that newly added url parameter must be optional because we dont need that parameter in normal cases. It's been purely using for  SEO.

Here is the Global.asax code.

 routes.MapRoute(
                "Default1", // Route name
                "{controller}/{action}/{id}/{id1}", // URL with parameters
                new { controller = "Home", action = "Index", id = UrlParameter.Optional, id1 = UrlParameter.Optional } // Parameter defaults
            );

Add the above code also in Global.asax Default route.

The action will be like this

[OutputCache(CacheProfile = "Cache1Hour")]
    public ActionResult Details(decimal id, string id1)
    {
        CDataStructLocationDetails objeDetails = new CDataStructLocationDetails{Id = id,Typeid        =3};
        return ViewEx(EnActions.Details, objeDetails);
        
    }

Sample Urls:
     www.yourdomain.com/Package/Details/5/Kerala-Honeymoon-Package.

Blank spaces in Urls replaced by %20 to avoid this we can send the name by replacing blank spces with '-'
here is the sample.

<%= Html.ActionLink("View Package Details", "Details",

                              new{id=item.Id,id1=item.PackageName.Trim().Replace(' ','-')})%>
