I couldn't agree more Swisslist; it only makes sense to look at this from the point of view of new content being added. I think ranking matters a lot but you also have to get it right in terms of what would cause the rankings to drop.While that works on your end, I don't know if that would work on my end. Besides, all you're doing is refreshing what is already on there. If you add new content, that "refreshes" it automatically and could help in your ranking. Obviously. And I don't think speeding up a site would help.
