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://a-moz.groupbuyseo.org/community/q/block-an-entire-subdomain-with-robots-txt
I hope that was helpful! Sorry about my English... I'm Spanish

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.

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

Should I submit a sitemap for a site with dynamic pages?
I have a coupon website (http://couponeasy.com)
White Hat / Black Hat SEO | | shopperlocal_DM
Being a coupon website, my content is always keeps changing (as new coupons are added and expired deals are removed) automatically. I wish to create a sitemap but I realised that there is not much point in creating a sitemap for all pages as they will be removed sooner or later and/or are canonical. I have about 8-9 pages which are static and hence I can include them in sitemap. Now the question is.... If I create the sitemap for these 9 pages and submit it to google webmaster, will the google crawlers stop indexing other pages? NOTE: I need to create the sitemap for getting expanded sitelinks. http://couponeasy.com/0 -

How would you optimize a new site?
Hi guys, im here to ask based on your personal opinion. We know in order to rank in SEO for a site is to make authority contents that interest people. But what would you do to increase your ranking of your site or maybe a blog post? leaving your link on blogs comment seem dangerous, nowadays. Is social media the only way to go?
