This guide works for Drupal 8 too!
We know you came here looking for the Google Tag Manager, Analytics, and Search Console set up information. However, we moved it to our Drupal SEO Guide.
When we wrote this blog post the summer of 2020 we didn't realize it would be quite so popular. And since it's a key part of getting your Drupal website's SEO completed, we decided to move it over there when it was time. Now you can find all the Drupal SEO How-to's in one place.
Just bookmark the Guide and you'll have it at your fingertips -- or get one of our Quick Start plans if you would like us to do the work for you.
