Not receiving SearchImpressionShare data when running a KEYWORDS_PERFORMANCE_REPORT for YESTERDAY (v201502)

[Alexander Falk]

I'm downloading keyword performance data into a SQL database for further analysis using the reporting API in Python. When I download data for exactly one day in the past, everything works fine and in the report XML file I get SearchImpressionShare data reported nicely for any single day in the past, except for yesterday.

The report definition I use is:

  # Create report definition.
  # See https://developers.google.com/adwords/api/docs/appendix/reports/keywords-performance-report for available fields
  report = {
      'reportName': 'Yesterday KEYWORDS_PERFORMANCE_REPORT',
      'dateRangeType': 'CUSTOM_DATE',
      'reportType': 'KEYWORDS_PERFORMANCE_REPORT',
      'downloadFormat': 'XML',
      'selector': {
          'fields': ['CampaignId', 'AdGroupId', 'Id', # 'CriteriaType',
                     # 'Criteria', 'FinalUrls',
                     'Impressions', 'Clicks', 'ConvertedClicks', 'Cost',
                     'AverageCpc', 'AverageCpm', 'AveragePosition', 'Ctr',
                     'ClickConversionRate', 'CostPerConvertedClick', 'QualityScore',
                     'FirstPageCpc', 'TopOfPageCpc', 'SearchImpressionShare'],
          'predicates': {
              'field': 'Status',
              'operator': 'IN',
              'values': ['ENABLED', 'PAUSED'],
              },
          'dateRange': {
              'min': datum,
              'max': datum,
              }
          },
      # Enable to get rows with zero impressions.
      'includeZeroImpressions': 'false'
  }

If the datum is any day in the past, the resulting XML report file that I receive has data in the SearchImpressionShare attribute. If I use yesterday's date, I get "--" for every single SearchImpressionShare attribute in all 4000 or so keywords.

Similarly, if I change the report definition to explicitly use 'YESTERDAY' instead of a custom date range, I also get "--" for the SearchImpressionShare attribute:

  report = {
      'reportName': 'Yesterday KEYWORDS_PERFORMANCE_REPORT',
      'dateRangeType': 'YESTERDAY',
      'reportType': 'KEYWORDS_PERFORMANCE_REPORT',
      'downloadFormat': 'XML',
      'selector': {
          'fields': ['CampaignId', 'AdGroupId', 'Id', # 'CriteriaType',
                     # 'Criteria', 'FinalUrls',
                     'Impressions', 'Clicks', 'ConvertedClicks', 'Cost',
                     'AverageCpc', 'AverageCpm', 'AveragePosition', 'Ctr',
                     'ClickConversionRate', 'CostPerConvertedClick', 'QualityScore',
                     'FirstPageCpc', 'TopOfPageCpc', 'SearchImpressionShare'],
          'predicates': {
              'field': 'Status',
              'operator': 'IN',
              'values': ['ENABLED', 'PAUSED']
          }
      },
      # Enable to get rows with zero impressions.
      'includeZeroImpressions': 'false'
  }

Does anybody know what's going on here? Is this a known issue?

Hi,

SearchImpressionShare is calculated for each day at a specific time, so you'll want to wait until after that time to retrieve that metric for the prior day.

For more information on when each metric is available, please see the Help Center article on data freshness.
