Preventing CNAME Site Duplications
-
Hello fellow mozzers!
Let me see if I can explain this properly.
First, our server admin is out of contact at the moment,
so we are having to take this project on somewhat blind. (forgive the ignorance of terms).We have a client that needs a cname record setup, as they need a sales.DOMAIN.com to go to a different
provider of data. They have a "store" platform that is hosted elsewhere and they require a cname to be
sent to a custom subdomain they set up on their end.My question is, how do we prevent the cname from being indexed along with the main domain? If we
process a redirect for the subdomain, then the site will not be able to go out and grab the other providers
info and display it. Currently, if you type in the sales.DOMAIN.com it shows the main site's homepage.
That cannot be allow to take place as we all know, having more than one domain with
exact same content = very bad for seo. I'd rather not rely on Google to figure it out.Should we just have the cname host (where its pointing at) add a robots rule and have it set to not index
the cname? The store does not need to be indexed, as the items are changed almost daily.Lastly, is an A record required for this type of situation in any way?
Forgive my ignorance of subdomains, cname records and related terms. Our server admin being
unavailable is not helping this project move along any. Any advice on the best way to handle
this would be very helpful! -
It is pointing to the other server now. We have it blocked from indexing on that end, just wanted to make sure that was enough.

No,
it is because you are pointing sales to a different sever, it seems to me that you don't have your dns set up correctly. you don't want sales pointing to your main website. -
So does this work better because Google will not show an IP address in search results?
-
You need to point your cname to the ip of the server that hosts your sales.domain.com
don't
Do
sales.domain.com > 123.123.123.123
where 123.123.123.123 is the ip of the hosting webserver.

Hello David,
I think with the robots rule (there are many examples out there) should be more than enough in your case! take a look at this helpful article: http://moz.com/community/q/block-an-entire-subdomain-with-robots-txt
I hope that was helpful! Sorry about my English... I'm Spanish

Server and multiple sites
We have multiple sites selling similar products in different ways but have always kept them separate on the off chance that google does not like it or they penalize one site. We have always put them on different servers but now thinking for performance as they are on shared hosting to put them on a single server which would be our own but we do not know the SEO considerations. We can assign multiple IPs to a server but I am not 100% sure whether there is still a negative impact of running multiple sites on the same server even if from a different IP. Any help would be appreciated, what I am really asking is could if they are on the same server with different IP's be still linked together by google?

Multiple sites in the same niche (Should we redirect these to our Main Site)
I will keep this short and sweet. We have some websites in the same niche area but want to focus only on our newest site (basically all the information that was being posted on the other sites will now be part of our new site) This will save us a lot of time and increase our focus on 1 entity. Should we redirect these website with a 301 redirect to the specific categories that they focus on in the new site? or should we redirect to the main domain.

Can links from an old site raise DA for other site? Or just unethical?
So this may be an odd question. So a competing company went out of business. Their domain name is now available. So just for research purposes, would you ever or would it be unethical for a person to buy an expired competing domain name, and point it to another site to collect their link juice? The site was only a DA of 10, but not sure if one - its bad to buy a competing companies expired domain - and two - even though in the same industry, this would be bad to point it to another site or create a site from it. Just curious your thoughts.

Am I Being Penalized For Having My Whole Site In A Subfolder Named With A Keyword?
I inherited a client. For some reason, their previous webmaster set up the site so everything is in a subfolder /law/. It's an attorney website. All the urls have the primary domain name /law/ and then assigned url. I can't image this is helping but could the site be penalized for this by Google or Bing? It's set up like this: www.attorneysite.com**/law/**therestoftheurl /law/ is included in EVERY PAGE... even the homepage.

But will these link be a Good BackLink that will increase our site's SEO Standing? The last one is exactly the same link , but this time coming from a News Site , such as http://teknologi.kompasiana.com/internet/2011/06/09/website-full-flash-dengan-inovasi-hebat-karya-indonesia/ , in this article (kompasiana is a very wellknown site news in Indonesia, in fact KOMPAS is the biggest newspaper firm in Indonesia) , our site is being featured , there is a link coming out of that article (DOFOLLOW), but will that link make our site much more SEO Friendly? Again please enlighten me 🙂

Can good penalize a site, and stop it ranking under a keyword permanently
hi all we recently took on a new client, asking us to improve there google ranking, under the term letting agents glasgow , they told us they used to rank top 10 but now are on page 14 so it looks like google has slapped them one, my question is can google block you permanently from ranking under a keyword or disadvantage you, as we went though the customers links, and removed the ones that looked strange, and kept the links that looked ok. but then there ranking dropped to 21, is it worth gaining new links under there main keyword even tho it looks like google is punishing them for having some bad links. the site is www. fine..lets...ltd...co....uk all one word cheers
