[
  {
    earnings: 10,
    hour: "15:00",
    impressions: 165,
    pageViews: 12,
    clicks: 5,
    url: "energiamundial.com.br",
    date: "2021-01-11"
  },
  {
    earnings: 20,
    hour: "16:00",
    impressions: 200,
    pageViews: 210,
    clicks: 65,
    url: "energiamundial.com.br",
    date: "2021-01-11"
  }
