Linking C Blocks

[Essential-Pest]

Hello everyone!

Just looking to get more information in regards to Linking C Blocks in layman's terms? We have dropped from 10 to 2 since the latest Moz Open Explorer update and are concerned about this score. Our highest competitor has doubled what they had on the last update.

Anyone who can provide more information about this, we would greatly appreciate it. Thanks ahead of time!

"It refers to the part of the IP address that's different. The same class C address means something has the same third octect in the address. In the following, the first three IPs are in the same class C, and the fourth address is not.

The reason we care is like what searchpl says -- it's a hint to Google that the sites are all related to each other and on the same server, and that the links may not be very natural since there is the good possibility that the same person set them up." (from Keri Morgret)
