First you have to go to routes folder of Laravel then web.php and in web.php you have to create routes to the page you want. Here i have created route for page youtube.
Now after creating route for youtube page you have to create that youtube page
So,in order to create youtube page go to resources and then views and then create new file named as youtube.blade.php and make service as you want.
Now go the the local browser and type localhost/101 (NOTE here 101 is parameter you can add your own parameter)
