Semantic Duplicate Conversion Actions

Two or more conversion actions in this account have different names but appear to track the same business event ("Purchase," "purchase-web," "Website Purchase"). Unless explicitly de-duplicated, these inflate measurement and confuse campaign-goal selection.

Why It Matters

Semantic duplicates are the harder cousin of strict duplicates. Two actions with literally the same configuration are easy to spot; two actions with near-identical configuration but different names slip past most reviews. They arise from team rotations (each new owner creates "their" version), tracking migrations (the old action stays alongside the new one), or template propagation (a sample action gets copied without being renamed properly). The damage: campaign goal setup includes ambiguous duplicates, conversion counts double when both are selected, and Smart Bidding learns from a signal split across redundant actions. AdLint identifies these by comparing categories, sources, and value methodology across same-event candidates.

How To Fix It

  1. AdLint's details list semantic-duplicate candidates.
  2. For each set, pick the canonical action (usually the most recently maintained one).
  3. In each active campaign's goal settings, switch from the duplicates to the canonical action.
  4. Archive (do not delete) the duplicates so historical data is preserved.
  5. Document the canonical action in team materials so future setup uses it by default.

Example

Configuration
Semantic duplicates:
  Purchase
  Purchase - Website
  Website Purchase
  purchase-web-2024

Fix: standardise on "Purchase. Website" (per naming convention), rewire campaigns, archive duplicates.
For Your Client Report

Google Ads conversion actions with different names but identical or near-identical semantic intent. Google's conversion-tracking documentation, multiple actions for the same business event must be explicitly deduplicated or they will double-count conversions when included in the same campaign goals. Fix: standardise on a canonical action per business event, rewire campaigns, and archive duplicates. Source: support.google.com/google-ads/answer/6386790.
