Compare performance by date range

Date Comparison makes it easy to evaluate the performance of campaigns over time and see the impact of changes. Advertisers now have another valuable tool to manage and improve the results of their search ad campaigns. You can:

  • See performance changes at a glance for all metrics in the scorecard, or for a single metric in the chart.

  • Easily compare to prior period or prior year: Comparing this week to last week is just a click away in the UI, as is comparing this month to the same month last year.

  • Set your own date ranges with Compare custom date ranges.

  • Download date comparison reports to Excel for more in depth reporting.

  • Compare by percentage change or absolute change so you can rely on the metric that is most important for your business.

  • See date comparisons in columns to easily sort and view multiple items.

  • Detect trends even with day of week variations with a chart that smartly aligns to show you the most meaningful performance comparisons.

  • Work effectively over longer time periods with automatic aggregation to weeks for ranges 3 months or longer.

Filters are only applied to the more recent date range. DS calculates the reporting data for the earlier date range without taking the filter into consideration.

Steps to compare date ranges

  1. In the DS UI, make sure you’re on a page that’s displaying statistics.
    If you’re on a Change history page, click the Statistics button in the upper righthand corner.

  2. In the date range selection tool in the upper righthand corner, select the first date range as usual.

  3. Select the Compare to past check box.

  4. Select the second date range in the dropdown that appears.

  5. Click Apply.
    • The performance summary graph provides a visual comparison of the two date ranges. Use the date range selection tool in the upper righthand corner as a key. You can change the displayed metric in the upper righthand corner of the graph, but you won’t be able to add a second metric.
    • The scorecard below the graph shows an arrow along with the percentage change (in most cases) for each metric, to indicate the difference from the first date range to the second.
    • The statistics table below the scorecard displays, for each metric:
      • % change: The percent the metric changed from range 1 to range 2.
      • # change: The amount the metric changed.
      • Week/Month/etc. 1: The amount for the first date range.
      • Week/Month/etc. 2: The amount for the second date range.
    • The comparison remains as you click through various pages (Change history only shows the first date).
