The express or beginner platform seems to be the one which you get sent to when you do a search for ‘Google Ads’. This express platform doesn’t have the step to add keywords and some other steps covered in the ‘Google Search Ads Setup’ Video.
Put https://ads.google.com into your browser and this should take you to the ‘expert mode’ setup process which, apart from the first page, follows the video almost exactly.
