The site was rising up nicely in Google and had reached page 1 for the main search term... until a couple of days again when it suddenly dropped down 7 places.
The only change I've made is to link the site to a Google+ page. I found the whole process a bit confusing, so maybe I've done something wrong that has caused Google to penalize the site.
The site is G & E Dental - Dentist Christchurch and the Google+ link is in the footer. If anyone can help I would be grateful. It might be just coincidence that it's suddenly dropped 7 places but seems strange it has followed a few days after adding Google+.
