Interlinking sites you own can be identified by Google
Many webmasters now a days have networks of sites. Google has expressed that using them to artificially increase rankings can be hazardous. They have methods of identifying “networked” sites. There are several ways they go about this to take note on:
Site hosted on the same web servers
Sites with similar IP addresses even if they are 22.231.113.64, 22.231.113.65
Similar site structure
Similar editors
Sites with the same CMS
Sites who use the same affiliate ID’s
Similar Adsense publisher code
Granted, Matt Cutts, Google spokesperson has stated that simply owning all the sites doesn’t automatically hurt you in the SERPS it’s just when you start to inter link them to build up artificial rankings in the search engines that you might start running into problems.
