Category Mismatch Between Settings and Report
A conversion action in your Google Ads conversion settings is labeled with one category (for example "Purchase") while the same action shows up under a different category (for example "Sign-up") in the Performance report row. Same name, two different categories across the two exports. The bidding logic and segmentation reports cannot both be right.
Why It Matters
Google Ads uses the conversion category in two places that you care about. It feeds the category-level rollups in the Conversions report (Purchase, Lead, Page view, etc), and it feeds Smart Bidding heuristics for which actions belong on the same funnel stage. When the category in settings drifts from the category recorded against historical volume, the rollups split the same action across two buckets and the funnel-stage views misclassify the work the action is actually doing. The usual root cause is harmless. Someone renamed or recategorized the action in Tools and Settings after a campaign had already accumulated volume under the old category. The Performance report keeps the historical category until enough new volume accrues to recategorize. The drift is silent and never raises a warning inside the Google Ads UI. The finding is info-level because the measurement loss is small, but the cleanup is worth doing for audit hygiene. Mismatched categories also make every "by category" report you hand to a client look slightly wrong, and clients notice.
How To Fix It
- Open the AdLint details and list each action where the settings category differs from the report category.
- Decide which category is correct for the underlying business event. Purchase for a paid order. Lead for a form-completed prospect.
- In Tools and Settings > Measurement > Conversions, open the action and confirm the category matches that decision.
- Annotate the change date so future period-over-period reports can explain the bucket shift.
- Wait one full reporting cycle. The Performance report will pick up the new category as new volume arrives.
Example
Settings: "Newsletter Signup" - category: Lead
Report: "Newsletter Signup" - category: Sign-up
Fix: align the settings category to match the intended funnel role.A Google Ads conversion action in this account has different category values in conversion settings versus the Performance report. Per Google Ads conversion-tracking documentation, the conversion category drives both rollup reporting and Smart Bidding funnel-stage heuristics. When the two exports disagree, category-level reports split historical volume across the wrong buckets and any "by category" analysis handed to a stakeholder will appear inconsistent. The usual root cause is a settings rename that has not yet propagated through historical performance data. Fix: confirm the correct category for the underlying business event, align the conversion settings, annotate the change date, and allow one reporting cycle for the report to reflect the new value.
