Hello all, To get benefit of link juice it is advisable to host all your website at different ips. but my question is, if my name server is same for all site but IP is different than is it fine? What crawler will consider in this case? thanks
There's no real need to host your sites on seperate I.P's at all. The domains will still benefit from link juice just as normal. I think you're confused. The only time to consider I.P's in SEO is when you are acquiring links from other websites, when getting links from other websites you don't want all of them to be on the same I.P otherwise Google would just think you're getting links through a fake network of sites all owned by one person.
Just avoid the temptation to cross link all your sites together, even if they are on separate ips. The search engines have ways of determining which sites are from the same person/company. It is not worth risking getting penalized or banned.
Matt Cutts from Google has stated that Google treats sites on the same IP exactly the same as if they were on different IPs. Google will count the links the same. However, if you abuse interlinking the sites it will be easier for Google to figure out that you own all the sites and then penalize you. Long story short, follow vansterdam's advice and don't interlink them unless the pages are related.
Having different IPs is correct as long as they do not have the same "IP Subnet Address" (i.e. the first 3 sets of numbers are the same). If they do and you crosslink them, you will get busted or even banned. G came down very hard 2 years ago for this. The SEO secret is to let all the sites obtain PR before you crosslink. And when you do, use only one link off of each home page. Or a smarter way is to link all but one to the "one" and not interlink at all.
unless you are doing interlinking between your all sites, then you do not need seperate IPs for each site. even from same Ip you can run multiple sites and do SOME interlinking as long as you dont go overboard to make it look like a netowrked sites designed to promote one another
@t_media i m not confuse regarding to IP or other stuff but my question is about name server... lets say i m hosted my website on same server using different IP. now here name server pointer will remain same but IP for all site will be differ. so, in this case will Google counted all sites of the same owner or different owner. One more thing i am not going to do mass internal linking between those sites. I just create those sites to promote main website. My purpose of these sites to promote my main website, now here main websites will get links from these simple static websites. thats why i m asking whether it will help or not? i did it for many sites but i am bit confuse regarding to same name server and different ip. I used to read matt cutts blog but i did not find that information there, it will be helpful if you post url from where you read this information Thanks for the advise, i used to do the same for my websites. sorry but i m not agree, If all site hosted on same ip pointing to only one sites than? lets say.... SIteA is main site which is hosted on xxx.xxx.xxx.001 Ip. now siteB, siteC, siteD, SiteE all are hosted on xxx.xxx.xxx.010 IP. in this case site b,d, d and e is promoting siteA so siteA will have some backlinks from all four sites. Now google will give less weight to those links. But if siteb ,c, d, and e are hosted on separate IP's than siteA will get more benefits for back links.
It is normal for many people to be sharing the same name servers. For example you could have 10 people on one server all using shared hosting. They will all be using the same name server. Therefore, theoretically Google, just by looking at name servers, cannot be certain the domains are all owned by the same person. So just as long as siteB, siteC, siteD, SiteE are all on seperate I.Ps and the domains are not registered under one name (or made private). Google should not be able to detect that they are all owned by you. Even if the name servers are identical for each.
As long as the sitesis not using the same IP. If different site is on the same IP, that is another issue...
Go on no problem, you will not face any problems.You can host all your website on different ips. Crawler doesnt take the consideration of name servers. Name servers work is to convert human readable domain to a numeric ip. No problem go on!
WHOIS information is freely obtained and so I would not be suprised if Google uses anything it can find in there to detect if a number of sites are associated with one person. Just look at the WHOIS for productreviewed.net and slothftw.com. It shows up that the registrant name is "Lucas Scholten" for both. If those 2 sites linked to one main site then Google might just think : "Those links aren't real, they're just coming from one person trying to create multiple links in order to manipulate rankings" I cannot be certain that Google takes this into account. But if I were building a search engine algorithm I'd certainly filter out links that all orginated from one identifiable source. To do this I would check I.P's and registration names. If you want to avoid any kind of possible detection you would have to do everything possible to leave no trace. This means either seperate name registration or purchasing the private WHOIS option on a domain i.e:use a domain proxy.
this is really good point, we must take care of it as every small things is important while working in SEO field. thanks for reply
