Matt Cutts says that he was able to quickly identify all the sites owned by two webmasters - whose sites he was reviewing at PubCon.
For the second site, for which he identified the owned had 50 or so other sites, he said "the owner was using Private WhoIs". How could he identify that the guy was the owner of these 50 sites, in just a few seconds, then? 数据挖掘研究院
My question is:
-If i *dont* interlink my sites (which i dont)
-If i do a private domain registration with DomainsByProxy so Google cant see who owns the domain in the WhoIs, and...
-If i don't put my name or company info on the site 数据挖掘研究院
....how can Google tell you own the sites? How how! ;-) I didnt think they could. And still don't.
Maybe im missing something 数据挖掘研究院
Ideas? Thanks
That session caused quite a buzz almost immediately. I think what we are seeing is partly related to the fact that Google is now officially a registrar and they can access Whois data. But there are many other ways for them to identify (or highly suspect) common domain ownership. 数据挖掘研究院
I noticed in the session that Matt first asked IF the person also owned those domains - he did not exactly declare it as a fact. He was mostly noting signs that the domains were related and that some of them were quite spammy in their apparent purpose.
>>Google is a registrar.
True, but that just tells Google who the domain registrar is. And “That’ is where the domain info is stored, your domain’s reseller. 数据挖掘研究院
Blocked means blocked.
Google has no more info than we do using whois.
Google has other ways, for example Adsense publisher code. AdWords accounts and Google analytics, and last but not least, Webmaster tools.
