Original working context:

- Step 2: Build a monthly analytics review template: which numbers to track, where to find them, and what 'good' looks like for each.
- Step 3: Write a 'content post-mortem' framework: after each piece of content, what 5 questions to ask to extract lessons.
- Step 4: Write the monthly content strategy review process: how to use last month's data to plan next month's content.
