Block a sub-domain from being indexed
-
This is a pretty quick and simple (i'm hoping) question. What is the best way to completely block a sub domain from getting indexed from all search engines?
One item i cannot use is the meta "no follow" tag.
Thanks! - Kyle

Keep in mind that Google Index's everything that it can crawl. Even if you put a block in the robots.txt they will probably crawl it. You can require a password to that subdomain and keep big G out. This is easy to do if you have a site with cpanel access. Just go to manage permissions, and password protect that director with a .htaccess pw.
-
The robots.txt file just tells the bots you would "prefer" they don't index but there is nothing to prevent them from indexing.The only sure way to do this is to restrict access to the sub-domain for everyone and require some sort of authentication. If they don't have access they can't index.
-
In subdomain.example.com/robots.txt add the statements:
User-agent: *
Disallow: /Warning: Be absolutely certain that the above statements are not included in your example.com/robots.txt file or you'll kill your site.
-
Each subdomain may have its own robots.txt file. So for that subdomain, you can put:
User-agent: * Disallow: /
In the robots.txt, and that should do it.
Please note that disallowing pages in robots.txt will not necessarily mean they won't appear on search result pages.... if people link to pages that are disallowed on that subdomain, they can still appear in SERPs. I had this happen with a few pages, which leads to funny listings in the SERPs because Google has to guess what the page title and description of the page should be, since it's not allowed to read the page. The meta noindex tag is the way to go if you want to be really sure the page doesn't appear in the SERPs. If you use that, don't disallow the page. Here's a recent SEOMoz post about it: http://www.seomoz.org/blog/robot-access-indexation-restriction-techniques-avoiding-conflicts

That was going to be my assumption but i wasn't 100% sure how they worked with sub domains. Are you able to supply a little more information on implementation? It is extremely important that it only blocks: sub.domain.com and not domain.com

Redirect multiple domains to 1 domain or not?
Hi there, I have client who has multiple domains that already have some PA and DA. Problem is that most websites have the same content and rank better on different keywords.
Technical SEO | | Leaf-a-mark
I want to redirect all the websites to 1 domain because it’s easier to manage and it removes any duplicate content. Question is if I redirect domain x to domain y do the rankings of domain x increase on domain y? Or is it better to keep domain x separately to generate more referral traffic to domain y? Thanks in advance! Cheers0 -
We switched the domain from www.blog.domain.com to domain.com/blog.
We switched the domain from www.blog.domain.com to domain.com/blog. This was done with the purpose of gaining backlinks to our main website as well along with to our blog. This set us very low in organic traffic and not to mention, lost the backlinks. For anything, they are being redirected to 301 code. Kindly suggest changes to bring back all the traffic.

Are images stored in Amazon S3 buckets indexable to your domain?
We're storing all our images in S3 bucket, common practice, but we want to get these images to drive traffic back to our site -- and credit for that traffic. We've configured the URLs to be s3.owler.com/<image_name>/<image_id>. I've not seen any of these images show in our web master tools. I am wondering if we're actually not going to get the credit for these images because technically they do sit on another domain. </image_id></image_name>

URL Structure On Site - Currently it's domain/product-name NOT domain/category/product name is this bad?
I have a eCommerce site and the site structure is domain/product-name rather than domain/product-category/product-name Do you think this will have a negative impact SEO Wise? I have seen that some of my individual product pages do get better rankings than my categories.

Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?
Dear all, starting with my .htaccess file: RewriteEngine On
Technical SEO | | inlinear
RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html
RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

How to determine which pages are not indexed
Is there a way to determine which pages of a website are not being indexed by the search engines? I know Google Webmasters has a sitemap area where it tells you how many urls have been submitted and how many are indexed out of those submitted. However, it doesn't necessarily show which urls aren't being indexed.

Umlaut in domain
Hi, My client wants to expand it's business to Germany and logically we need a domain name to match. We've found a great one and regsiterd several variants to it. However I just found out that in Germany it is possible (while here it's not) to register a domain with an umlaut. My question is: will google assign more value to: schädlinge.de than schadlinge.de when users search for schädlinge? If yes, how large will the difference be? (I will use an umlaut in the title etc) Kind regards,
