The use of multiple nameservers is a very good way to maximize the SEO value of your hosting without having to resort to multiple hosting accounts or many different servers. A good SEO host like Got Web Host can help you get unlimited nameservers all on a single server. Coupled with unique class C IP’s, these nameservers can give you ease of use and high value for your SEO projects.
When it comes to building a network of sites there are some simple things that can be done to help increase your rankings. It used to be good enough to just have a different domain name for each site, but then the search engines started seeing those domains sharing IP addresses and often the value of some of those sites would be decreased. Then came the advent of using different domain names all on individual IP addresses. This is a good solution that for some people still works today, if you have a small network of sites or the different sites within your network are optimized for very different keywords. If you intend to build a large network of sites and work in many different, but possibly similar (or even the same) keywords, using different nameservers is the way to go.
When you register your domain it will ask for the nameserver for that domain. This tells the registrar where the domain resides and where to resolve the traffic to. If you have 100 domains all on the same server all using the same IP, then search engines like Google may see them all as the same or similar site. You may find some sites get good rankings, but you may also have many sites that don’t rank well at all. If you were to have a server that had each of those domains on its own IP address with a different nameserver for each of them it would make each site appear to be a stand alone site and there would be no common threads pulling them all together. This will give you maximum SEO value on each domain. For example, if you have three different domains and they are all on the same server, same IP and same nameserver and they are optimized for the same or similar keywords, then the search engines may eventually see them as all similar/same sites. They may rank one of them well and not the other two or maybe choose to rank none of them well. Linking between them will be of reduced value since they are all looked at as basically the same site. All your hard work will have been for nothing. If all three domains had their own IP and each domain had its own nameserver, now the search engines will see each domain as being a single stand alone site that has nothing in common with the other two sites. Now you can freely link between them, and if all are optimized for the same keyword you can rank well for all of them. Imagine having the top three spots for your chosen keyword!
Having different nameservers makes each site appear to be a stand alone site independent from the others so you can link freely between them. This can help making a large interlinked network of sites much easier to build and maintain.
While some people may not find much value in using multiple nameservers, anyone that is serious about building a network of sites that they would like to all have rank well in the search engines should strongly consider using them. It is a fast, easy and affordable solution that adds tremendous SEO value to your sites and can help you avoid setbacks that you may encounter if you keep all your domains on the same IP and nameserver.
