# Campaign trends explore The Campaign trends explore compares your paid campaigns across time. It puts ad spend, paid visits, cost per visit, cost per conversion and ROAS on the days you pick beside the same days 7 days earlier and 52 weeks earlier, what those weekdays typically see, and an expected range. ## Good to know - Every number is the [Campaigns](/docs/analytics/campaigns) explore's, compared: spend, credit and paid visits are read the same way. - Filter **Date** to pick the days to look at; every comparison follows them. - Each comparison is a metric of its own, named after its metric, such as **ROAS (7 days earlier)**. - Only complete days are rows. A day is the ad account's own for spend, and your organisation's for visits and credit. ## Used on dashboards Charts on these [dashboards](/docs/analytics/dashboards) are built on the Campaign trends explore: - **Trend and anomaly: what changed and why?**: Week over week, Year over year, Unusual days and What drove it ## Dimensions The Campaign trends explore has 9 dimensions. ::field-table | Dimension | Type | Description | | --- | --- | --- | | Date | Date | The day being looked at: the ad account's day for spend, and the organisation's for visits and credit.

Empty while any of those days is in Kontala's first recorded week. | | 52 weeks earlier | The same days 52 weeks earlier, so each weekday meets its own: year over year. Empty until Kontala has recorded 52 weeks before every one of the days. | | Typical | What these days usually see: the average of the same weekdays in the 8 weeks before, or in as many of them as Kontala has recorded. For a ratio, the same weekdays in the 8 weeks before, or in as many of them as Kontala has recorded, added up before dividing, so a busy week counts for more than a quiet one. | | Expected low | The bottom of the expected range: 95% of normal periods land between the expected low and high, read from how much the same weekdays varied in the weeks before. Needs 4 weeks of them. | | Expected high | The top of the expected range: 95% of normal periods land between the expected low and high, read from how much the same weekdays varied in the weeks before.
