Error from add criteria

[Roy]

When adding many keywords to the same campaign, I get the following
APIException from google:

"The campaigns for this customer already have the maximum number of
active keywords permitted, so this campaign may not be activated."

(Error code 17)


My questions are:
1) At this point, can I buy more ad groups / creatives / negative
keywords?
2) What does it mean "this campaign may not be activated."? Do I need
to do something special in order to activate it now?

Thanks,

Roy

Hi,

In regards to your questions:

1) It is not possible to increase the amount of keywords per ad group
or per account. You should either try to remove unnecessary keywords
or create new AdWords accounts for large campaigns.

2) I'm not sure what this error message means exactly, but I don't
think your campaign was deactivated. Let me know if you see any
problems with ad serving.

Best,
