Welcome to the Q&A Forum

Hi there, The SERPs and other information presented in the Keyword Difficulty tool are going to be for whatever search engine you choose. The only thing that isn't going to be is the Search Volume data. That will always show Bing data because we lost access to Google's API a while back. Instead of leaving this blank, we still wanted to show a snapshot of volume. This has no effect on the score so you're safe there. Hope this helps clear things up!
