Getting Started with Contribution to Change
Contribution to Change is available for all consolidated dashboards: Campaigns, Keywords, and Search Terms. (this is also showing SA-only sections; can we enable a non-SA view to get a more accurate screenshot? How?)
You can find the data under when toggling Compare Mode in the top right Date Range.
How to Use Contribution to Change
The total CTC equals the Total Change %, i.e. how much the metric has changed period-to-period, and is the sum of all the individual components. Sorting CTC by descending order for a positive total CTC (and ascending order for a negative total CTC) helps you find the top contributor for the change in that period.
