I've heard (unfortunately now I cannot find link where I've read it) that Google plans to build a portfolio of domain owners. For example I own 50 domains. All of them are on different hosting accounts so that IPs and DNS differ. It would help in SEO when I make links network between my sites. But if Google has portfolio and all domains are registered with me the Google knows that all domains belong to the same person and that this link are not natural and my sites doesn't benefit from this linking. What do you think? Does it looks to be possible?
i don't think that google will keep this.as u know that there are millions of webmaster in the world and it is not easy to keep track on it. every day they are buying and selling their domains and other will purchase the domain.so just think they have to update the owner name and hosting and lots of things.i will become messy.
and I think that it is not much more difficult than to consider DNS and IPs. This is simplified process description: Every domain owner has id. Every site has corresponding owner_id. If site Ð links to site B and owner_id is the same then value of this link = value/100 But just imagine how big challenge against SEO this could be
but if owner A have 100 domains ok.now owner A have sold his 5 domains to owner B and other % to C.now google have to keep track that owner A have sold domain to B now he need to add it this info to all owner and edit the info.so imagine now,there are millions of owner it need large amount of data storage and they have to develop good program for that.it will cost more and worth less for google.
Reciprocal links check is IMHO more complicated thing. Network detections - even more complicated. So it's possible and I believe it can improve results. But I just wonder if somebody heard if Google planned or planning to implement such thing. I think Google became domain registrar specially to have access to all domain owners data.
