Extensions import settings
When you import extensions with a CSV file or the "Make multiple changes" tool, you might have new extensions that differ from existing ones only in their URL fields.
For example, suppose you have several new sitelinks with the same link text as existing sitelinks, but different final URLs. You might want to edit the URLs of the existing sitelinks (for example, to add tracking codes), or you might want to create new sitelinks with different URLs (for example, to test a different landing page for the same link text).
To specify how AdWords Editor should treat the imported extensions, select one of the options below from Tools > Settings (Windows) or AdWords Editor > Preferences (Mac).
On the General tab in the settings dialog, locate the Import heading and the drop-down menu labeled When importing sitelinks and app extensions with different final URLs. Then choose one of the following options.
- Change existing URLs to new URLs (default)
With this option selected, you can use CSV import or the Make multiple changes tool to edit URLs of existing extensions. You can't create two sitelinks that differ only in URLs using CSV import or the Make multiple changes tool.
- Create new ad extension if final URL is different
Extensions that differ only in URLs are considered distinct, so you can use CSV import or the Make multiple changes tools to create a new extension that differs from an existing one only in the URL field.
