Django has built-in support for it via the django.contrib.sitemaps framework. Below is a complete step-by-step guide:

Step 1: Enable the Sitemap Framework

In your settings.py, make sure the following app is added:

INSTALLED_APPS = [
    # other apps...
    'django.contrib.sites',
    'django.contrib.sitemaps',
]

Also, set your SITE_ID (if you’re using the sites framework):

SITE_ID = 1

If you’re not using django.contrib.sites, that’s fine — Django will still generate sitemaps correctly.

Step 2: Create a Sitemap Class

In one of your apps (for example, blog), create a file called sitemaps.py.

Example:

# blog/sitemaps.py
from django.contrib.sitemaps import Sitemap
from django.urls import reverse
from .models import Post  # your model

class PostSitemap(Sitemap):
    changefreq = "weekly"
    priority = 0.8

    def items(self):
        return Post.objects.filter(published=True)

    def lastmod(self, obj):
        return obj.updated_at

You can also make a sitemap for static views:

class StaticViewSitemap(Sitemap):
    priority = 0.5
    changefreq = "monthly"

    def items(self):
        return ['home', 'about']

    def location(self, item):
        return reverse(item)

Step 3: Add a Sitemap URL

In your project’s main urls.py, include the sitemap view:

# project/urls.py
from django.contrib import sitemaps
from django.contrib.sitemaps.views import sitemap
from django.urls import path, include
from blog.sitemaps import PostSitemap, StaticViewSitemap

sitemaps = {
    'posts': PostSitemap,
    'static': StaticViewSitemap,
}

urlpatterns = [
    path('admin/', admin.site.urls),
    path('sitemap.xml', sitemap, {'sitemaps': sitemaps},
         name='django.contrib.sitemaps.views.sitemap'),
]

Step 4: Verify It Works

Run your development server:

python manage.py runserver

Then visit:

http://localhost:8000/sitemap.xml

You should see an XML sitemap with your URLs listed.

Also, do not forget to add your web app's sitemap to Google Webmaster Tools and Bing Webmaster Tools.
