How to compare organic traffic year over year, and find the weeks that moved it
The YoY setup is its own ritual: same-period-last-year comparison, weekly grain, then the drill for the weeks that did the damage. Verdict included, one sentence.
Before, the dashboard ritual
8 steps · 3 menus · 1 weekly drill
- Open the growth dashboard
- Dates: last 12 complete weeks
- Comparison: previous year, same period
- Metric: Clicks
- Granularity: weekly
- Read the two lines
- Drill: Dates table
- Find the weeks with the biggest drops
After, one question
How do my organic clicks compare to the same 12 weeks last year, which weeks drove the change, and is the drop real?
Paste it into Claude, ChatGPT or Cursor with Quattr MCP connected. No tool names, no field names, routing is the assistant's job.
The answer
How do my clicks compare to the same 12 weeks last year, and is the drop real?
