I have a .co.uk that I've been working on for a while. Got around 50ish pages indexed and the site was ranking on the first page for the exact term. So the domains was widgets.co.uk and the site was ranking for "widgets". Now for the last week the site is now next to last for its exact term. I hadn't done anything to the site, except acquired one link from an authority site that was well aged. Has anyone else had this happen on their sites in the last week or so?
