Clicks with extension showing column
Displays the number of clicks on ads that were showing an ad extension, as reported by Google Ads.
Note that this column does not display the total number of clicks in the report's summary row or performance summary graph. Because the column shows clicks on any part of an ad when a particular ad extension was showing, the number in an individual row may include clicks on other extensions that currently appear in the report. If the summary row or graph added these two individual rows together, some of the clicks would be counted twice and the summary amount would be inflated.
