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://a-moz.groupbuyseo.org/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.

Moz was unable to crawl your site? Redirect Loop issue
Moz was unable to crawl your site on Jul 25, 2017. I am getting this message for my site: It says "unable to access your homepage due to a redirect loop. https://kuzyklaw.com/ Site is working fine and last crawled on 22nd July. I am not sure why this issue is coming. When I checked the website in Chrome extension it saysThe server has previously indicated this domain should always be accessed via HTTPS (HSTS Protocol). Chrome has cached this internally, and did not connect to any server for this redirect. Chrome reports this redirect as a "307 Internal Redirect" however this probably would have been a "301 Permanent redirect" originally. You can verify this by clearing your browser cache and visiting the original URL again. Not sure if this is actual issue, This is migrated on Https just 5 days ago so may be it will resolved automatically. Not sure, can anybody from Moz team help me with this?

Spam sites with low spam score?
Hello! I have a fair few links on some of the old SEO 'Directory' sites. I've got rid of all the obviously spammy ones - however there are a few that remain which have very low spam scores, and decent page authority, yet they are clearly just SEO directories - I can't believe they service any other purpose. Should we now just be getting rid of all links like this, or is it worth keeping if the domain authority is decent and spam score low? Thanks Sam

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.

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
