Major kw combos too strong?

Same ads across entire site

[adfree]

My site is very strong in two, three related marketing terms. Pages dealing with related tools do not show ads supporting these tools and techniques but the site's major kw combos :-(

Is there any way I can "weaken" the site's strong major kw's that dominate AS ads?

On individual pages you can use section targeting [google.com] to add and subtract weight from specific areas of text.
