The nature of our pages is such that our main keywords are in <h1> and <h2> headings, but zero to only one or two uses of those same keywords are in the content under the <h2> headings. Does anyone think Google penalizes for having few-to-zero keywords under the <h2> headings? Should I just remove the <h2>'s and let those keywords be content under the <h1> keywords?
Thanks for the response, caveman. The <h1> and <h2> tags all have the main keyword in common, but not others (eg. "widget information"; "widget types"; "widget history").
I'll think about how to do what you have suggested..the nearly-duplicate pages will have to be on the same website, otherwise other factors (e.g. inbound links, PR) are going to affect their different SERPs positions, too.
