except simple www which is a prefix i sincerly don't know for sure what www1, www2 (and so on) stands for If anyone is using www1 , www2 or whatever...please post and make some light around this problem have a wonderful day !
The number that follows the “WWW†indicates that the data being retrieved by the Web browser is gathering the information from a different Web server than the one that serves the typical “WWW†address.
if i would like to use something like www1. or www2. what should i do ? does it give your site another IP too ?
Any site that allows you to access its URLs as www.*, www1.* www2.*, etc. in an attempt to do load balancing is just plain dumb. A) They have no knowledge of managing a web farm and B) they have no knowledge of the SEO impacts of doing so. By doing this, you create URL canonicalization issues... duplicate content AND split page rank. If you want to do load balancing then it should only be because you have several web servers serving up the same web site (i.e. a server "farm"). And this is NOT the way to implement load balancing. You buy a load balancing device and place it in front of your server farm. You set the DNS entry for your domain to point to the IP of the load balancer instead of a particular web server. When someone requests a page from your site, they will be directed by DNS to the balancer. Let the load balancer pick which web server serves up the page request. ALL of the web servers can then be serving up pages as www.yourdomain.com. It's transparent to the user (and the URL) whether you have a single server or a farm of web servers serving up the domain.
This is super interesting. I understand the SEO aspect of all of this, but at what point would a site need to start balancing the load on their servers? What size sites require this. Are we talking big mysapce type sites or is this necessary on a site that maybe serves 150k pages a day or something...I guess it would depend on cpu useage?..it's all new to me so sorry if I sound like a dumb ass, but I'm curious now.
Yes those are just sub domains and many times connected to diffrent servers for load balancing people name it www1 coz its easy to manage i guess
i got your point, but look at this site, they have a large amount of traffic. Are they doing it well, using www2.* ? www[dot]autovit[dot]ro and www2[dot]autovit[dot]ro as far as i can see there is no PageRank splitting and i think they are gaining more and more traffic.... Any explanation ? thanks again, have a good day
No they are doing a horrible job. As you can see by doing a site:autovit.ro command at google.ro they have URLs indexed both ways. Canonicalization issues, duplicate content issues, split page rank/link juice... Terrible idea and they probably get crap for traffic so don't really need load balancing. The LEAST they could have done was add a <link rel="canonical" href="URLofTheirCanonicalURL"> to each page on their site so that at least Google, Yahoo!, and Bing would be able to resolve the canonical URL even if other search engines still will not be able to.
