This could be because:\n\n- The entities are ineligible for display.\n- They could have been paused within the report's date range.\n\nWith query results, you often want to obtain information about how your\ncampaigns are performing. In this context, zero metrics may not be\ndesirable. To produce a more useful report, you can explicitly exclude zero\nmetrics.\n\nExclude zero metrics with a predicate\n-------------------------------------\n\nA predicate is an expression that evaluates to `TRUE`, `FALSE`, or `UNKNOWN`.\nThey are used in the search condition of the `WHERE` clauses in\n[Google Ads Query Language](/google-ads/api/docs/query/structure).\n\nThe following query demonstrates how to explicitly remove zero metrics with\na predicate: \n\n SELECT\n campaign.id,\n metrics.impressions\n FROM campaign\n WHERE metrics.impressions \u003e 0\n\nExclude zero metrics by segmenting\n----------------------------------\n\nZero metrics are always excluded when segmenting a report, provided all\n*selected* metrics are zero (see [below](#rows_returned)).\n\nSegmenting a report is done by including any `segments` field in the search\nquery. For example, if you segment a report by `segments.date`, metrics are\nbroken down with one row for each date. Dates with no metrics are not returned\nin such a report.\n\nFor the following query, the report won't include zero metric rows: \n\n SELECT\n campaign.name,\n metrics.impressions,\n segments.date\n FROM campaign\n WHERE segments.date DURING LAST_30_DAYS\n\nReturned rows with zero metrics\n-------------------------------\n\nRows whose selected metrics are all zero won't be returned.\n\nFor example: \n\n SELECT\n ad_group_criterion.criterion_id,\n metrics.impressions,\n metrics.clicks,\n metrics.conversions,\n segments.date\n FROM keyword_view\n WHERE segments.date BETWEEN \u003cdate1\u003e AND \u003cdate2\u003e\n\nThe resulting report won't contain any rows in which all three selected metrics\nare zero.\n\nIn situations where you retrieve data older than the\n[retention period](//ads-developers.googleblog.com/2024/10/new-data-retention-policy-for-google-ads.html),\nthe resulting report won't contain any rows for data older than the retention\nperiod. All account data, including performance metrics, billing information\nand historical reports, are retained for a period of 11 years."]]
