Hi Matei,
When you are using
TargetingIdeaService to get stats for keywords, if a particular keyword is not returned in the results, this means that there isn't enough search volume for this keyword in the context of AdWords and hence the service cannot give you a good estimate of search volume. Other restrictive parameters, like language and location, provided in the request might be the reason for stats not showing up in the results.
Could you provide the complete SOAP XML request and response logs so that I can look into it? Please use Reply privately to author when responding.
Thanks,
Shwetha, AdWords API Team.
