My company does design, hosting and
seo for physicians across the country. Back in February we seemed to have lost all of our Google positions, and we are still trying different things to see whats going on. One of the things someone mentioned was the fact that all our sites (about 140) were on the same IP address and had very similar Whois information, and they linked between themselves. They all have very different content, specifically related to that doctor and their practice. We perform real well on MSN and Yahoo but just nowhere to be found on Google, are they penalizing us because of the IPs? or because we are linking our sites with each other in a national resource list?
Any help would be really really really appreciated!
