I have a web site with approximately 500 static .html pages cached in Google. I'm trying to update each page at least every other month, but haven't been successful. I was wondering if any of you know of a tool or a method for me to follow the pages (all of them at once like Digitalpoint Keyword Ranking tool - not one at a time) so that I know when a page was last indexed in G so that I can update the indexed pages since the last update. Any help would be greatly appreciated.
