You can ask this question:
- When you upload a list of keywords using CSV.
- When you add keywords from one ad group to another.
- When you add search terms as keywords to another ad group.
- When you add keywords from the Keyword Discovery to your ad groups.
The general rule is that if you try to upload the same keywords into the same group, you will see an alert message, and SplitMetrics Acquire will not allow you to add duplicates to the same ad group. However, you can add them to different groups, so you need to be careful not to have the same keywords across multiple ad groups. In the future, we will improve the deduplication mechanism to prevent this; for right now, please bear this in mind.
When you try to add them, you will get an alert message. You can download an error report from here to see which keywords are duplicates. Select add only keywords without errors to add the keywords.
