Lost Traffic Analysis: Non-Causal Attribution
How to attribute traffic loss without overclaiming causation.
Lost traffic is a decline in impressions or clicks over time. Analyzing it honestly — without overclaiming causation — is essential for trustworthy reporting. This guide covers how to analyze lost traffic with non-causal attribution. See Local SEO Analytics for the measurement framework.
Identifying lost traffic
- Compare impressions and clicks over the current and previous period.
- Filter by query, page, device, and country to localize the decline.
- Check if the decline is sudden (possible algorithm update or technical issue) or gradual (possible content decay).
- Check if the decline affects one page, one query, or the whole site.
Identifying contributors (not causes)
| Contributor | How to check |
|---|---|
| Ranking drop | Compare position before and after the decline |
| CTR drop | Compare CTR before and after the decline |
| Query lost | Check if a specific query stopped triggering impressions |
| Page lost | Check if a specific page stopped receiving impressions |
| Technical issue | Check the Coverage report for new errors |
Reporting lost traffic
Report what declined, when, and the likely contributors. Propose actions to recover the traffic, but do not promise recovery. See the Monthly Local SEO Reporting Checklist.
