We’ve been getting reports of odd search volume numbers over the last few weeks. The AdWords API started having issues with their search volume numbers beginning at the end of last month. From looking at a lot of keywords, it seems as though the global volume numbers are more reliable than the local search volume figures. We have seen some odd global volume numbers though.
We know August is coming up, and we’re still pulling search volume figures for newly added keywords, just beware … they may not match exactly what you see in the AdWords Keyword Tool.
As of today, there’s no word on when we’ll have good data via the AdWords API again. We’ll make sure to refresh data for all our keywords once we can confirm everything is working the way it should.
