After a short research in this Group (should have be done as first step...) there are the answers to my question:
1. "related" vs. "additional" keywords and how to remove them: http://groups.google.de/group/adwords-api/browse_thread/thread/b246a23087f946f1/c94fa20106f92815?lnk=gst&q=additional+keywords+#c94fa20106f92815 2. About n-gram groups: http://groups.google.com/group/adwords-api/browse_thread/thread/b1d3189f4483c78d a very useful explaination 3. The n-gram parameter in the v2009 API http://code.google.com/intl/de-DE/apis/adwords/v2009/docs/reference/TargetingIdeaService.NgramGroupsSearchParameter.html 4. further about synonyms (additional keywords) in the search results: http://groups.google.com/group/adwords-api/browse_thread/thread/dd91fb012cd2f26d Best regards, Dian -- You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
