Delta Analysis

The Delta Analysis feature allows you to compare selected metrics against a previous time period.

The Delta Analysis feature allows you to compare selected metrics against a previous time period — both percentage change and absolute change are calculated automatically. This is useful for quickly identifying trends, performance gains, or drops over time without manually calculating differences.

What the Delta Feature Does

When enabled, Delta Analysis adds an additional layer to your visualizations and tables:

• Absolute Delta – Shows the numeric difference between the current period and the selected comparison period.

• Percentage Delta – Shows the relative change as a percentage.

Example: If your Impressions for this month are 120,000 and last month they were 100,000:

• Absolute Delta: +20,000

• Percentage Delta: +20%

How to Use Delta Analysis

1. Enable Delta

1. Open the dashboard, chart, or table where you want to compare data.

2. Locate the Delta Analysis toggle (usually in the chart/table settings panel).

3. Switch it ON.

2. Choose the Comparison Period

1. After enabling Delta Analysis, a comparison period selector will appear.

2. Select the period you want to compare against — for example:

   • Previous month

   • Same month last year

   • Custom date range

3. The system will automatically align the periods based on the same granularity (day, week, month).

3. Select the Metric

• If you are viewing a chart, ensure that a metric (e.g., Impressions, Clicks, Revenue) is selected — without a metric, the delta cannot be calculated.

• If you are viewing a table, the delta columns will be shown alongside each selected metric.

4. View the Delta

• Charts: Deltas will be visible as labels, tooltips, or secondary lines/bars (depending on the visualization type).

• Tables: Two additional columns are displayed for each metric:

  • Δ (Absolute) — numeric difference

  • Δ% — percentage change

---

Best Practices

• Use consistent time periods for meaningful comparisons (e.g., compare a full month to another full month).

• When comparing seasonal data, select the same period last year for better context.

• For volatile metrics (e.g., daily conversions), consider using weekly or monthly aggregation to reduce noise.

---

Limitations

• Delta is calculated only when the primary metric and comparison period are set.

• If the comparison period contains no data, Delta values will be blank.

• Currently, Delta works on numeric metrics only (counts, sums, averages) — not categorical dimensions.

Example Use Cases

• Campaign performance: Compare CTR of a current campaign to last week.

• Sales trend: Compare this month’s revenue to the same month last year.

• Traffic growth: See percentage growth in unique visitors compared to the previous quarter.
