What are Annotations in Google Analytics?
Annotations are small notes that will help you to keep track of important events like marketing campaigns, new filters, important mentions, theme changes, goals, etc. They will help you understand spikes in traffic, unusual changes, and trends on your analytics.

Types of Annotations
There are 2 types of annotations in Google Analytics:
- Shared: This will be seen by any person who has access to the property reports.
- Private: This will only be available to you.
