I am using ng-view to include AngularJS partial views, and I want to update the page title and h1 header tags based on the included view. These are out of scope of the parti

When I had to solve this, I couldn't place the ng-app on the page's html tag, so I solved it with a service:

angular.module('myapp.common').factory('pageInfo', function ($document) {

    // Public API
    return {
        // Set page <title> tag. Both parameters are optional.
        setTitle: function (title, hideTextLogo) {
            var defaultTitle = "My App - and my app's cool tagline";
            var newTitle = (title ? title : defaultTitle) + (hideTextLogo ? '' : ' - My App')
            $document[0].title = newTitle;
        }
    };

});

Thanks to tosh shimayama for his solution.
I thought it was not so clean to put a service straight into the $scope, so here's my slight variation on that: http://plnkr.co/edit/QJbuZZnZEDOBcYrJXWWs

The controller (that in original answer seemed to me a little bit too dumb) creates an ActionBar object, and this one is stuffed into $scope.
The object is responsible for actually querying the service. It also hides from the $scope the call to set the template URL, which instead is available to other controllers to set the URL.

A clean way that allow dynamically setting title or meta description. In example I use ui-router but you can use ngRoute in same way.

var myApp = angular.module('myApp', ['ui.router'])

myApp.config(
    ['$stateProvider', function($stateProvider) {
        $stateProvider.state('product', {
            url: '/product/{id}',
            templateUrl: 'views/product.html',
            resolve: {
                meta: ['$rootScope', '$stateParams', function ($rootScope, $stateParams) {
                    var title = "Product " + $stateParams.id,
                        description = "Product " + $stateParams.id;
                    $rootScope.meta = {title: title, description: description};
                }]

                // Or using server side title and description
                meta: ['$rootScope', '$stateParams', '$http', function ($rootScope, $stateParams, $http) {
                    return $http({method: 'GET', url: 'api/product/ + $stateParams.id'})
                        .then (function (product) {
                            $rootScope.meta = {title: product.title, description: product.description};
                        });
                }]

            }
            controller: 'ProductController'
        });
    }]);

HTML:

<!DOCTYPE html>
<html ng-app="myApp">
<head>
    <title ng-bind="meta.title + ' | My App'">myApp</title>
...

The better and dynamic solution I have found is to use $watch to trace the variable changes and then update the title.

Alternatively, if you are using ui-router:

index.html

<!DOCTYPE html>
<html ng-app="myApp">
<head>
    <title ng-bind="$state.current.data.title || 'App'">App</title>

Routing

$stateProvider
  .state('home', {
      url: '/',
      templateUrl: 'views/home.html',
      data: {
        title: 'Welcome Home.'
      }
  }

If you don't have control over title element (like asp.net web form) here is some thing you can use

var app = angular.module("myApp")
    .config(function ($routeProvider) {
                $routeProvider.when('/', {
                                            title: 'My Page Title',
                                            controller: 'MyController',
                                            templateUrl: 'view/myView.html'
                                        })
                            .otherwise({ redirectTo: '/' });
    })
    .run(function ($rootScope) {
        $rootScope.$on("$routeChangeSuccess", function (event, currentRoute, previousRoute) {
            document.title = currentRoute.title;
        });
    });
