What happens when duplication occurs in keyword management or manual addition of keywords because some of them already exist in the PPC campaigns?
If you add a number of new keywords manually with the 1-Click Setup to a Broad-campaign, but some of them already exist in other campaigns like Exact or Phrase, these keywords will simply get skipped. We will delete no old keywords and create no new ones - we just skip them.
This skipping also applies if a keyword or search term is to be transferred with an automation or individual rule. In this case the duplicate will not appear in the logs because it was skipped.
