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

What is the best strategy to SEO Discontinued Products on Ecommerce Sites?
RebelsMarket.com is a marketplace for alternative fashion. We have hundreds of sellers who have listed thousands of products. Over 90% of the items do not generate any sales; and about 40% of the products have been on the website for over 3+ years. We want to cleanup the catalog and remove all the old listings that older than 2years that do not generate any sales. What is the best practice for removing thousands of listings an Ecommerce site? do we 404 these products and show similar items? Your help and thoughts is much appreciated.

Is this campaign of spammy links to non-existent pages damaging my site?
My site is built in Wordpress. Somebody has built spammy pharma links to hundreds of non-existent pages. I don't know whether this was inspired by malice or an attempt to inject spammy content. Many of the non-existent pages have the suffix .pptx. These now all return 403s. Example: https://www.101holidays.co.uk/tazalis-10mg.pptx A smaller number of spammy links point to regular non-existent URLs (not ending in .pptx). These are given 302s by Wordpress to my homepage. I've disavowed all domains linking to these URLs. I have not had a manual action or seen a dramatic fall in Google rankings or traffic. The campaign of spammy links appears to be historical and not ongoing. Questions: 1. Do you think these links could be damaging search performance? If so, what can be done? Disavowing each linking domain would be a huge task. 2. Is 403 the best response? Would 404 be better? 3. Any other thoughts or suggestions? Thank you for taking the time to read and consider this question. Mark

Suspicious external links to site have 302 redirects
Hi, I have been asked to look at a site where I suspect some questionable SEO work, particularly link building. The site does seem to be performing very poorly in Google since January 2014, although there are no messages in WMT. Using WMT, OPenSiteExplorer, Majestic & NetPeak, I have analysed inbound links and found a group of links which although are listed in WMT, etc appear to 302 redirect to a directory in China (therefore the actual linking domain is not visible). It looks like a crude type of link farm, but I cant understand why they would use 302s not 301s. The domains are not visible due to redirects. Should I request a disavow or ignore? The linking domains are listed below: http://www.basalts.cn/

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.

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.

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
