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?

Site traffic halved not sure why
Hi guys, not sure if anyone can help, but we had a client's google organic traffic literally halve from the week at the end of August to September (29 Aug 2016 to be precise) and it hasn't recovered since (here's a screenshot from GA http://puu.sh/sAmd3/b071dd1e57.png) I've been doing a lot of digging around on Moz and elsewhere about any Google updates that may have gone through around that time and there doesn't seem to be anything that I would think would affect it. I thought it might be to do with Penguin, but that doesn't seem to be the case. A while ago before then we did have some domains and pages 301 redirected to the main site when multiple other sites were rolled into the one, but I wouldn't have thought that should affect it. After that I've also gone and removed all those sites and redirects too (couple of weeks ago) but that doesn't seem to have fixed it. There's no black hat SEO done on the site so very odd to have this happen. I'm rather out of ideas what it could be that has impacted things so suddenly and that we couldn't get it recovered from. Any ideas would be much appreciated.

Does google give any advantage to Webmaster tools verified sites?
Hello friends, I am seeing a strange pattern. i register 2 new domain and make sites on them and add no backlinks nothing only put content and did on page seo right. After 1month of google indexing. both sites are not showing in search for the targeted keywords, but as soon as i add them to Google Webmaster tools they both automatically comes to the 16th and 24th number for their specific keywords. So my question is does Google give any advantage to sites which are verified and added into its webmaster tools in terms of seo or authority?

Removing duplicated content using only the NOINDEX in large scale (80% of the website).
Hi everyone, I am taking care of the large "news" website (500k pages), which got massive hit from Panda because of the duplicated content (70% was syndicated content). I recommended that all syndicated content should be removed and the website should focus on original, high quallity content. However, this was implemented only partially. All syndicated content is set to NOINDEX (they thing that it is good for user to see standard news + original HQ content). Of course it didn't help at all. No change after months. If I would be Google, I would definitely penalize website that has 80% of the content set to NOINDEX a it is duplicated. I would consider this site "cheating" and not worthy for the user. What do you think about this "theory"? What would you do? Thank you for your help!

Is Syndicated (Duplicate) Content considered Fresh Content?
Hi all, I've been asking quite a bit of questions lately and sincerely appreciate your feedback. My co-workers & I have been discussing content as an avenue outside of SEO. There is a lot of syndicated content programs/plugins out there (in a lot of cases duplicate) - would this be considered fresh content on an individual domain? An example may clearly show what I'm after: domain1.com is a lawyer in Seattle.
White Hat / Black Hat SEO | | ColeLusby
domain2.com is a lawyer in New York. Both need content on their website relating to being a lawyer for Google to understand what the domain is about. Fresh content is also a factor within Google's algorithm (source: http://moz.com/blog/google-fresh-factor). Therefore, fresh content is needed on their domain. But what if that content is duplicate, does it still hold the same value? Question: Is fresh content (adding new / updating existing content) still considered "fresh" even if it's duplicate (across multiple domains). Purpose: domain1.com may benefit from a resource for his/her local clientale as the same would domain2.com. And both customers would be reading the "duplicate content" for the first time. Therefore, both lawyers will be seen as an authority & improve their website to rank well. We weren't interested in ranking the individual article and are aware of canonical URLs. We aren't implementing this as a strategy - just as a means to really understand content marketing outside of SEO. Conclusion: IF duplicate content is still considered fresh content on an individual domain, then couldn't duplicate content (that obviously won't rank) still help SEO across a domain? This may sound controversial & I desire an open-ended discussion with linked sources / case studies. This conversation may tie into another Q&A I posted: http://moz.com/community/q/does-duplicate-content-actually-penalize-a-domain. TLDR version: Is duplicate content (same article across multiple domains) considered fresh content on an individual domain? Thanks so much, Cole0 -

Victim of Negative SEO - Can I Redirect the Attacked Page to an External Site?
My site has been a victim of Negative SEO. During the course of 3 weeks, I have received over 3000 new backlinks from 200 referring domains (based on Ahref report). All links are pointing to just 1 page (all other pages within the site are unaffected). I have already disavowed as many links as possible from Ahref report, but is that all I can do? What if I continue to receive bad backlinks? I'm thinking of permanently redirecting the affected page to an external website (a dummy site), and hope that all the juice from the bad backlinks will be transferred to that site. Do you think this would be a good practice? I don't care much about keeping the affected page on my site, but I want to make sure the bad backlinks don't affect the entire site. The bad backlinks started to come in around 3 weeks ago and the rankings haven't been affected yet. The backlinks are targeting one single keyword and are mostly comment backlinks and trackbacks. Would appreciate any suggestions 🙂 Howard
