Users can set a date range to be used at the chart, page, or report level. By default, Data 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.

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.
