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

Does ID's in URL is good for SEO? Will SEO Submissions sites allow such urls submissions?
Example url: http://public.beta.travelyaari.com/vrl-travels-13555-online It's our sites beta URL, We are going to implement it for our site. After implementation, it will be live on travelyaari.com like this - "https://www.travelyaari.com/vrl-travels-13555-online". We have added the keywords etc in the URL "VRL Travels". But the problems is, there are multiple VRL travels available, so we made it unique with a unique id in URL - "13555". So that we can exactly get to know which VRL Travels and it is also a solution for url duplication. Also from users / SEO point of view, the url has readable texts/keywords - "vrl travels online". Can some Moz experts suggest me whether it will affect SEO performance in any manner? SEO Submissions sites will accept this URL? Meanwhile, I had tried submitting this URL to Reddit etc. It got accepted.

Duplicate keywords in URL?
Is there such a thing as keyword stuffing URLs? Such as a domain name of turtlesforsale.com having a directory called turtles-for-sale that houses all the pages on the site. Every page would start out with turtlesforsale.com/turtles-for-sale/. Good or bad idea? The owner is hoping to capitalize on the keywords of turtles for sale being in the URL twice and ranking better for that reason.

Tags on WordPress Sites, Good or bad?
My main concern is about the entire tags strategy. The whole concept has really been first seen by myself on WordPress which seems to be bringing positive results to these sites and now there are even plugins that auto generate tags. Can someone detail more about the pros and cons of tags? I was under the impression that google does not want 1000's of pages auto generated just because of a simple tag keyword, and then show relevant content to that specific tag. Usually these are just like search results pages... how are tag pages beneficial? Is there something going on behind the scenes with wordpress tags that actually bring benefits to these wp blogs? Setting a custom coded tag feature on a custom site just seems to create numerous spammy pages. I understand these pages may be good from a user perspective, but what about from an SEO perspective and getting indexed and driving traffic... Indexed and driving traffic is my main concern here, so as a recap I'd like to understand the pros and cons about tags on wp vs custom coded sites, and the correct way to set these up for SEO purposes.

Site being targeted by hardcore porn links
We noticed recently a huge amount of referral traffic coming to a client's site from various hard cord porn sites. One of the sites has become the 4th largest referrer and there are maybe 20 other sites sending traffic. I did a Whois look up on some of the sites and they're all registered to various people & companies, most of them are pretty shady looking. I don't know if the sites have been hacked or are deliberately sending traffic to my client's site, but it's obviously a concern. The client's site was compromised a few months ago and had a bunch of spam links inserted into the homepage code. Has anyone else seen this before? Any ideas why someone would do this, what the risks are and how we fix it? All help & suggestions greatly appreciated, many thanks in advance. MB.

Would linking out to a gambling/casino site, harm my site and the other sites it links out to?
I have been emailed asking if I sell links on one of my sites. The person wants to link out to slotsofvegas[dot]com or similar. Should I be concerned about linking out to this and does it reduce the link value to any of the other sites that the site links out to? Thanks, Mark
