Add me to Google Analytics and Search Console

These two tools answer different questions. Analytics tells you what people did once they arrived. Search Console tells you how they found you. I usually want both, and read-only access is enough for either.

Google Analytics

1. Go to analytics.google.com and make sure the right property is selected at the top.
2. Click the gear icon (Admin) in the bottom left.
3. In the Property column, click Property access management.
4. Click the + in the top right, then Add users.
5. Enter my email address, leave Notify new users by email ticked, and choose the Viewer role.
6. Click Add.

Viewer is all I need to read the data. If you would like me to set up conversion tracking or fix the configuration, use Editor instead.

Google Search Console

1. Go to search.google.com/search-console and select your site.
2. Click Settings in the left sidebar.
3. Click Users and permissions.
4. Click Add user, enter my email, and choose Full or Restricted.

Restricted lets me see everything. Full additionally lets me submit sitemaps and request re-indexing, which is usually what you actually want if I am doing any SEO work.

If your site is not in Search Console at all

That is common and it is not a problem — it just means nobody set it up. Tell me and I will add it, which needs one small verification step on the site itself.
