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.

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 🙂

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

The use of a ghost site for SEO purposes
Hi Guys, Have just taken on a new client (.co.uk domain) and during our research have identified they also have a .com domain which is a replica of the existing site but all links lead to the .co.uk domain. As a result of this, the .com replica is pushing 5,000,000+ links to the .co.uk site. After speaking to the client, it appears they were approached by a company who said that they could get the .com site ranking for local search queries and then push all that traffic to .co.uk. From analytics we can see that very little referrer traffic is coming from the .com. It sounds remarkably dodgy to us - surely the duplicate site is an issue anyway for obvious reasons, these links could also be deemed as being created for SEO gain? Does anyone have any experience of this as a tactic? Thanks, Dan

Merging four sites into one... Best way to combine content?
First of all, thank you in advance for taking the time to look at this. The law firm I work for once took a "more is better" approach and had multiple websites, with keyword rich domains. We are a family law firm, but we have a specific site for "Arizona Child Custody" as one example. We have four sites. All four of our sites rank well, although I don't know why. Only one site is in my control, the other three are managed by FindLaw. I have no idea why the FindLaw sites do well, other than being in the FindLaw directory. They have terrible spammy page titles, and using Copyscape, I realize that most of the content that FindLaw provides for it's attorneys are "spun articles." So I have a major task and I don't know how to begin. First of all, since all four sites rank well for all of the desired phrases-- will combining all of that power into one site rocket us to stardom? The sites all rank very well now, even though they are all technically terrible. Literally. I would hope that if I redirect the child custody site (as one example) to the child custody overview page on the final merged site, we would still maintain our current SERP for "arizona child custody lawyer." I have strongly encouraged my boss to merge our sites for many reasons. One of those being that it's playing havoc with our local places. On the other hand, if I take down the child custody site, redirect it, and we lose that ranking, I might be out of a job. Finally, that brings me down to my last question. As I mentioned, the child custody site is "done" very poorly. Should I actually keep the spun content and redirect each and every page to a duplicate on our "final" domain, or should I redirect each page to a better article? This is the part that I fear the most. I am considering subdomains. Like, redirecting the child custody site to childcustody.ourdomain.com-- I know, for a fact, that will work flawlessly. I've done that many times for other clients that have multiple domains. However, we have seven areas of practice and we don't have 7 nice sites. So child custody would be the only legal practice area that has it's own subdomain. Also, I wouldn't really be doing anything then, would I? We all know 301 redirects work. What I want is to harness all of this individual power to one mega-site. Between the four sites, I have 800 pages of content. I need to formulate a plan of action now, and then begin acting on it. I don't want to make the decision alone. Anybody care to chime in? Thank you in advance for your help. I really appreciate the time it took you to read this.
