gistfile1.txt

// This will pull impression share data into a script for you to use:

  function main() {
    var accountIterator = MccApp.accounts().get();
    var mccAccount = AdWordsApp.currentAccount();
    while (accountIterator.hasNext()) {
      var account = accountIterator.next();
      MccApp.select(account);
      var accountName = account.getName();

      Logger.log(accountName);

      var report = AdWordsApp.report(
        "SELECT CampaignName, SearchImpressionShare, SearchRankLostImpressionShare, SearchBudgetLostImpressionShare " +
        "FROM CAMPAIGN_PERFORMANCE_REPORT " +
        "WHERE AdvertisingChannelType IN [SEARCH] " +
        "DURING THIS_MONTH", {
          includeZeroImpressions: false
        });
      var rows = report.rows();
      while (rows.hasNext()) {
        var row = rows.next();
        var cName = row['CampaignName'];
        var iShare = row['SearchImpressionShare'];
        var iShareRank = row['SearchRankLostImpressionShare'];
        var iShareBudget = row['SearchBudgetLostImpressionShare'];
      }
    }
  }
