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

Why is this site ranked #1 in Google with such a low DA (is DA not important anymore?)
Hi Guys, Would you mind helping me with the below please? I would like to get your view on it and why Google ranks a really new domain name #1 with super low domain authority? Or is Domain Authority useless now in Google? It seems like from the last update that John Mueller said that they do not use Domain Authority so is Moz Domain Authority tool not to take seriously or am I missing something? There is a new rehab in Thailand called https://thebeachrehab.com/ (Domain authority 13)It's ranked #1 in Google.co.th for these phrases: drug rehab thailand but also for addiction rehab thailand. So when checking the backlink profile it got merely 21 backlinks from really low DA sites (and some of those are really spammy or not related). Now there are lots of sites in this industry here which have a lot higher domain authority and have been around for years. The beach rehab is maybe only like 6 months old. Here are three domains which have been around for many years and have much higher DA and also more relevant content. These are just 3 samples of many others... <cite class="iUh30">https://www.thecabinchiangmai.com (Domain Authority 52)</cite>https://www.hope-rehab-center-thailand.com/ (Domain Authority 40)https://www.dararehab.com (Domain Authority 32) These three sites got lots of high DA backlinks (DA 90++) from strong media links like time.com, theguardian.com, telegraph.co.uk etc. (especially thecabinchiangmai.com) but the other 2 got lots of solid backlinks from really high DA sites. So when looking at the content, thebeachrehab.com has less content as well. Can anyone have a look and let me know your thoughts why Google picks a brand new site, with DA 13 and little content in the top compared to competition? I do not see the logic in this? Cheers

I noticed some drops on some keywords before that happens (in June and July) but it all of it was related to web design keywords for local Qatar, but all other keywords that related to SEO and digital marketing were not have any changes and been on top My site was ranked number 1 on google search results for "digital marketing qatar" and some other keywords, but the main URL had been removed from 100% of all search results. but you can still see it on the map only. I just tried to submit it again to Google and to index it through google search console tool but still not get any results, Recently, based on google console, I found some new links but I have no idea how it been added to links of my website:

Can any one help to know what is the reason?? and how can I solve this issue without losing my previous ranked keywords? Can I submit a direct message to google support or customer service to know the reason or get help on this issue? Thanks & Regards0 -
Site Footer Links Used for Keyword Spam
I was on the phone with a proposed web relaunch firm for one of my clients listening to them talk about their deep SEO knowledge. I cannot believe that this wouldn’t be considered black-hat or at least very Spammy in which case a client could be in trouble. On this vendor’s site I notice that they stack the footer site map with about 50 links that are basically keywords they are trying to rank for. But here’s the kicker shown by way of example from one of the themes in the footer: 9 footer links:

The canonical for each page links back to itself. I simply can’t believe Google doesn’t consider this Spammy. Interested in your view.

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

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 dropped suddenly. Is it due to htaccess?
I had a new site that was ranking on the first page for 5 keywords. My site was hacked recently and I went through a lot of trouble to restore it. Last night, I discovered that my site was nowhere to be found but when i searched site: mysite.com, it was still ranking which means it was not penalized. I discovered the issue to be a .htaccess and it have been resolved. My question is now that the .htaccess issue is resolved , will my site be restored back to the first page? Is there additional things that i should do? I have notified google by submitting my site
