Last year we increased the limits for all advertisers to 500 campaigns and 3 million keywords per AdWords account. Today, in response to feedback from many of our advertisers, we are pleased to announce yet another AdWords campaign limit increase.
It is now possible to have 10,000 campaigns (includes active and paused campaigns) per account. With this change, it is now possible to easily manage and monitor more campaigns in a single place.
AdWords Editor, the AdWords API, and all other AdWords services are compatible with the new limits.
A full list of all account limits, including creative and ad extension limits, is available in the AdWords Help Center.
