- Changes in auction dynamics
- Changes in tracked conversions
- Shifts in spend mix
- Renaming campaigns
The correct answer is: Renaming campaigns
Renaming campaigns wouldn’t change an account’s optimization score
Scores may even decrease if Google’s algorithm identifies new headroom in your account, such as changes in auction dynamics, an update to tracked conversions, and shifts in spend between campaigns. But Renaming the campaign wouldn’t change an account’s optimization score.
