Zero metrics in search results
When you execute a query, you may encounter metrics for entities that are zero. This could be because:
- The entities are ineligible for display.
- They could have been paused within the report's date range.
With query results, you often want to obtain information about how your campaigns are performing. In this context, zero metrics may not be desirable. To produce a more useful report, you can explicitly exclude zero metrics.
Exclude zero metrics with a predicate
A predicate is an expression that evaluates to
They are used in the search condition of the
WHERE clauses in
Google Ads Query Language.
The following query demonstrates how to explicitly remove zero metrics with a predicate:
SELECT campaign.id, metrics.impressions FROM campaign WHERE metrics.impressions > 0
Exclude zero metrics by segmenting
Zero metrics are always excluded when segmenting a report, provided all selected metrics are zero (see below).
Segmenting a report is done by including any
segments field in the search
query. For example, if you segment a report by
segments.date, metrics are
broken down with one row for each date. Dates with no metrics are not returned
in such a report.
For the following query, the report won't include zero metric rows:
SELECT campaign.name, metrics.impressions, segments.date FROM campaign WHERE segments.date DURING LAST_30_DAYS
Returned rows with zero metrics
Rows whose selected metrics are all zero won't be returned.
SELECT ad_group_criterion.criterion_id, metrics.impressions, metrics.clicks, metrics.conversions, segments.date FROM keyword_view WHERE segments.date BETWEEN <date1> AND <date2>
The resulting report won't contain any rows in which all three selected metrics are zero.
