Summary rows appear at the bottom of each reporting table. They aggregate totals for each column that displays metrics. In the example below, the last three rows are summary rows for a keywords reporting table in a Google Ads engine account.
Not available for all columns
Some columns do not display summary data because the individual rows already aggregate metrics. For example, the Clicks with extension showing 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 added these two individual rows together, some of the clicks would be counted twice and the summary amount would be inflated.
In this case, the summary row displays "---" to avoid inflated totals.
