OnPage Grader double counting keywords on responsive site (hidden vs visible)

[GregB123]

FYI - it appears that if you have a responsive site that has blocks of text that are duplicated, but Hidden or Visible depending on the screen width, that On-Page Grader will count any keywords in that text twice.

I have text shown in one location to Desktop users that needed to be re-located to a different part of the page for Tablet and Phone users to keep the layout nice. And my OP Grader keyword count doesn't match what I saw on the page doing Ctrl-F to find the keywords, unless you count the Hidden text. (not hidden like cloaking or some black hat thing - just not displayed on certain devices)

I guess On Page Grader just reads the source code and ignores whether the text is hidden or visible. It would be nice if it read the code as if it was a Desktop device. (suggestion for Moz staff)

Does anybody know if Google also ignores device dependent Hidden vs Visible areas???
