We’ve been covering more keyword planner bugs here within the Google AdWords system that Google algorithm updates in the past couple weeks, which is unusual.

Well, the last one that prevented those with active campaigns from using the tool seems to have been fixed last night. There are still going to be many of you unable to use the tool because of the new restrictions but those who are not technically blocked from using the full tool should be able to now.

I am seeing reports in the ongoing Google AdWords Help thread and many posts on Twitter sharing that the issue is now resolved:

Good to hear.

Sorry to those who cannot use the tool to the restrictions.
