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

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?

Should I delete older posts on my site that are lower quality?
Hey guys! Thanks in advance for thinking through this with me. You're appreciated! I have 350 pieces of Cornerstone Content that has been a large focus of mine over the last couple years. They're incredibly important to my business. That said, less experienced me did what I thought was best by hiring a freelance writer to create extra content to interlink them and add relevancy to the overall site. Looking back through everything, I am starting to realize that this extra content, which now makes up 1/3 my site, is at about 65%-70% quality AND only gets a total of about 250 visitors per month combined -- for all 384 articles. Rather than spending the next 9 months and investing in a higher quality content creator to revamp them, I am seeing the next best option to remove them. From a pros perspective, do you guys think removing these 384 lower quality articles is my best option and focusing my efforts on a better UX, faster site, and continual upgrading of the 350 pieces of Cornerstone Content? I'm honestly at a point where I am ready to cut my losses, admit my mistakes, and swear to publish nothing but gold moving forward. I'd love to hear how you would approach this situation! Thanks 🙂

How to make second site in same niche and do white hat SEO
Hello, As much as we would like, there's a possibility that our site will never recover from it's Google penalties. Our team has decided to launch a new site in the same niche. What do we need to do so that Google will not mind us having 2 sites in the same niche? (Menu differences, coding differences, content differences, etc.) We won't have duplicate content, but it's hard to make the sites not similar. Thanks

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.
