Why you might not have explanations

Explanations are designed to showcase significant changes to the performance metrics that your campaign is optimising towards. However, you may find that explanations aren't always available. Here are a few common reasons for the unavailability of explanations:

• Metric is not aligned to campaign goals: Explanations will only trigger for the performance metrics that your campaign is optimising towards because fluctuations in other metrics are expected but not indicative of campaign success or performance issues. For example, explanations for changes in click volume or conversion value on a campaign using the Maximise conversions bid strategy because its success is measured based on conversions and cost.
• Change is not significant enough to trigger an explanation: Explanations will not trigger for smaller changes in either percentage or absolute numbers (for example, low number of total conversions). This is to ensure that we’re only highlighting significant changes since these smaller variations in performance are expected.
• Date range includes today or goes further back than the last 90 days: Explanations are only available for periods within the last 90 days. You can still view the percentage change for more than 90 days, but the explanations window won’t show. Similarly, you won’t see explanations if your date range contains today’s date because there may be more data for the day.
• Campaign type and bid strategy availability: Explanations are currently only available for some campaign types and bid strategies.
