Date range usage
Users can set a date range to be used at the chart, page, or report level. By default, Looker Studio sets it to the most recent 28-day period excluding today.
This date range is used differently, depending on the Ahrefs report type:
- Historical. The report type uses the date range to constrain historical data by a start and end date.
- Start date only. The report type uses the start date value, but ignores the end date value (and always returns data up to today).
- Comparison. The report type returns metrics for the provided end date, as well as comparison metrics for the provided start date.
- Crawl selection. The report type is used to select a Site Audit crawl. A date range selects the completed crawl with the most recent start time in the specified date range. For more information, see Date range usage in Site Audit reports.
Some fields in each tool's field reference have a "Used with date range" indicator. The meaning of this depends on how the field's report type uses the date range.
- If the usage is Historical, then the field is used as the date field to constrain by start/end date.
- If the usage is Start date only, then the field’s value is affected by the date range.
- If the usage is Comparison, then the field is a comparison metric.
