Annotations let you mark significant dates on your charts, helping you correlate traffic patterns with real-world events like campaigns, product launches, or website changes.

Use Cases

  • Campaign launches — Mark when a new ad campaign started to see its impact on traffic
  • Website changes — Track deployments, redesigns, or content updates
  • External events — Note industry events, holidays, or competitor actions
  • Technical issues — Document outages or tracking issues for future reference
  • Seasonal patterns — Mark recurring events to compare year-over-year

​
Creating an Annotation

Annotation creation form

​
Viewing Annotations

Annotations appear as vertical markers on time-series charts. Hover over a marker to see the annotation details.
Use consistent colors to categorize your annotations. For example, use blue for campaigns, green for releases, and red for incidents.

Best Practices

  1. Be specific — Include enough detail in the description to understand the event months later
  2. Use accurate times — Set the correct timezone to align annotations with your traffic data
  3. Keep titles short — Use concise titles that fit on the chart without cluttering
  4. Clean up old annotations — Remove annotations that are no longer relevant to keep charts readable
