Google announced on Google+ that by November 10, 2014, they will be renaming a few columns within the Google AdWords reporting interface to be consistent with the Google Analytics naming convention.
Google said, "three of the Google Analytics reporting columns in AdWords will be re-named to match the corresponding column names in Google Analytics."
What is changing?
- Pages / visit to Pages / session
- Avg. visit duration (seconds) to Avg. session duration (seconds)
- % new visits to % new sessions
If any of your internal reporting tools reference these old names, make sure to update them before your reports break.
The changes go into effect November 10th.
