Keyword Difficulty tool showing Google search volume or Bing?

[SpaMedica]

Hi,

I plugged in a bunch of keywords to know their search volume, chose Google from the drop down and then chose English from the next dropdown and clicked on Check dificulty.

It shoes me "Bing Search Volume (Exact Match)" on top but shows the name of the keyword and "for Google CA" on the left.

Is the search volume for Google? or Bing? and the difficulty as well? Google or Bing?

We use Bing for the search volume estimations regardless of the search engine you select. Google doesn't share their search volume information with us, so we aren't able to include Google search volume in the tool. Still, the Keyword Difficulty score that we calculate does take the search engine into account, so if you're looking to get a sense of how difficult it is to rank in the top 10 in Google, our difficulty score will reflect that.

Nick -  Probably a dumb question but I want to confirm my understanding.   I know all search Volume metrics are estimates at best, but .... reporting a search volume from Bing as 100 searches/month is intended to represent actual searches on Bing, right?   Assuming Google gets 5-10 times more search volume depending on the keyword, in terms of actual volume a keyword If I see a kw that gets 100 searches on Bing, it might get 500+ on Google (just broadly estimating), correct?

Just wanted to confirm that Moz doesn't adjust the Bing volume to account for their lower share of search, and normalize the numbers up to estimate the search volume across all search engines.

Thanks!
