Conversion metric dropped suddenly with no recent deployments; debug instrumentation causes
Distinguishing real regressions from telemetry pipeline failures. Segment by device, channel, and geography to spot uniform loss signaling a tagging break; verify vendor delays and sampling; check for consent or ad-blocker shifts.
Tests separating real conversion loss from instrumentation drift by isolating dimensions and validating pipeline health without code changes. First, determine if the drop is uniform across segments (device, geo, channel) suggesting a global tagging or attribution failure. Second, check for vendor-side changes like processing delays, sampling thresholds, or attribution model updates. Third, investigate environmental shifts such as consent-banner updates, ad-blocker proliferation, or browser privacy changes suppressing events.
