Ive recently put together a Keyword List of about 100 keywords on the Moz Keyword Explorer tool. One keyword, aerial filming, stood out as very low search volume of 51 - 100. I took the same 100 keywords and passed them through the Google Keyword Planner by Google AdWords. Aerial Filming has an average search volume of 1k - 10k according to the Keyword Planner. Even though Keyword Planner gives me a range of 1k - 10k, the lowest number is still 10 times higher than what the Moz Keyword Explorer was indicating. This drastic difference of volume was consistent across all 100 keywords. All of the Monthly Volume numbers were divided by 10.
Why does Moz Keyword Tool display a search volume that is 10x less than what Google Keyword Planner is suggesting?
