Talking specifically about the keyword "widget support" did you delete it and start a new ad group containing that keyword only after you created a new landing page? Is the file name of the landing page “widget support.htm” or “widget-support.htm”? On the Landing page, how many different keywords are in the meta tags? Is there any third party advertising on the landing page (adsense, yahoo publisher, affiliate links)?
