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

Spammers created bad links to old hacked domain, now redirected to our new domain. Advice?
My client had an old site hacked (let's call it "myolddomain.com") and the hackers created many links in other hacked sites with links such as http://myolddomain.com/styless.asp?jordan-12-taxi-kids-cheap-T8927.html The old myolddomain.com site was redirected to a different new site since then, but we still see over a thousand spam links showing up in the new site's Search Console 404 crawl errors report. Also, using the links: operator in google search, we see many results of spam links. Should we be worried about these bad links pointing to our old site and redirecting to 404s on the new site? What is the best recommendation to clean them up? Ignore? 410s? Other? I'm seeing conflicting advice out there. The old site is hosted by the client's previous web developer who doesn't want to clean anything up on their end without an ongoing hosting contract. So beyond turning redirects on or off, the client doesn't want to pay for any additional hosting. So we don't have much control over anything related to "myolddomain.com". 😞 Thanks in advance for any assistance!

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>

Are .clinic domains effective?
We acquired a .clinic domain for a client, they are right now running under a .ca and I was just wondering if there were any cons to making the switch. On the flip side are there any pros? I've tried to search for the answer but couldn't seem to come across anything, thank you if you have any knowledge or could point me to a resource.

Blocked URL parameters can still be crawled and indexed by google?
Hy guys, I have two questions and one might be a dumb question but there it goes. I just want to be sure that I understand: IF I tell webmaster tools to ignore an URL Parameter, will google still index and rank my url? IS it ok if I don't append in the url structure the brand filter?, will I still rank for that brand? Thanks, PS: ok 3 questions :)...

Block Baidu crawler?
Hello! One of our websites receives a large amount of traffic from the Baidu crawler. We do not have any Chinese content or do any business with China since our market is Uk. Is it a good idea to block the Baidu crawler in the robots.txt or could it have any adverse effects on SEO of our site? What do you suggest?

Instant Indexing
I've been working on a site for a while now, methodically building content and building trust and authority. Lately I've noticed that anything I publish there appears to be instantly indexed by Google, which surprises me. I haven't had this happen before so I'm curious. I'd be interested to hear the experience of others.

How do I check if my IP is blocked?
We changed servers and where our sites once ranked very highly (page 1 for all sites), they now are nowhere to be seen. Someone suggested that our IP might be blocked. Someone else suggested SEOMoz was the place to go to get it checked. Any help would be GREATLY appreciated. With thanks. Bryan

Multiple Domains, Same IP address, redirecting to preferred domain (301) -site is still indexed under wrong domains
Due to acquisitions over time and the merging of many microsites into one major site, we currently have 20+ TLD's pointing to the same IP address as our "preferred domain:" for our consolidated website http://goo.gl/gH33w. They are all set up as 301 redirects on apache - including both the www and non www versions. When we launched this consolidated website, (April 2010) we accidentally left the settings of our site open to accept any of our domains on the same IP. This was later fixed but unfortunately Google indexed our site under multiple of these URL's (ignoring the redirects) using the same content from our main website but swapping out the domain. We added some additional redirects on apache to redirect these individual pages pages indexed under the wrong domain to the same page under our main domain http://goo.gl/gH33w. This seemed to help resolve the issue and moved hundreds of pages off the index. However, in December of 2010 we made significant changes in our external dns for our ip addresses and now since December, we see pages indexed under these redirecting domains on the rise again. If you do a search query of : site:laboratoryid.com you will see a few hundred examples of pages indexed under the wrong domain. When you click on the link, it does redirect to the same page but under the preferred domain. So the redirect is working and has been confirmed as 301. But for some reason Google continues to crawl our site and index under this incorrect domains. Why is this? Is there a setting we are missing? These domain level and page level redirects should be decreasing the pages being indexed under the wrong domain but it appears it is doing the reverse. All of these old domains currently point to our production IP address where are preferred domain is also pointing. Could this be the issue? None of the pages indexed today are from the old version of these sites. They only seem to be the new content from the new site but not under the preferred domain. Any insight would be much appreciated because we have tried many things without success to get this resolved.
