Hi, For example, I have 2 site A and B hosted in same server (means same IP address). Now if I link from site A to another site C(in different IP address) and then site C links to site B, will Google treat this as "reciprocal links"? Pls give me advice. Thanks.
It is not reciprocal link exchange, it is called 3 way link exchange for example: person1 having 2 sites => siteA and siteB person2 having 1 site => siteC not persong1 ask person2 to place siteA's liink on siteC in return he will place siteC's link on siteB this is called 3 way link exchange Note: it will be batter if persone1 having both site hosted in different server.
Yes three way link building is Good and Easier then one way link building. And yes it's okay with Google also.
google doesnt give much importance to links from same ip adresses.Try getting links from different ip adresses.......that will give you more weightage.And yes......three way links are more effective.
Does IP have any weight here? Because I think 2 site A and B in same IP address will be considered as 1 site only.
No, its not reciprocal linking. Its a three way linking. In reciprocal linking only tow sites can participate.
As far as I know, it is ok. But you have to build that third site, making it have ocntent and PR so that you can get the links.
