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

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.

<sub>& <sup>tags, any SEO issues?</sup></sub>
Hi - the content on our corporate website is pretty technical, and we include chemical element codes in the text that users would search on (like S02, C02, etc.) A lot of times our engineers request that we list the codes correctly, with a <sub>on the last number. Question - does adding this code into the keyword affect SEO? The code would look like SO<sub>2</sub>.</sub> Thanks.

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.

Tutorial For Moving Blogger Blog From Sub-Domain to Sub-Directory
Does anyone know where I can find a tutorial for moving a blogger.com (blogspot) blog that's currently hosted on a subdomain (i.e. blog.mysite.com) to a subdirectory (i.e. mysite.com/blog) with the current version of blogger? I'm working on transferring my blogger blogs over to wordpress, and to do so without losing link juice or traffic, this is one of the steps I have to take. There's plenty of tutorials that address moving from blogspot.mysite.com to wordpress and I've even found a few that address moving from blog.mysite.com (hosted on blogger) to a root domain mysite.com. However, I need to move from blog.mysite.com (blogger) to mysite.com/blog/ - subdirectory (wordpress). Anyone who knows how to do this or can point me in the right direction?? Thanks.

How to block "print" pages from indexing
I have a fairly large FAQ section and every article has a "print" button. Unfortunately, this is creating a page for every article which is muddying up the index - especially on my own site using Google Custom Search. Can you recommend a way to block this from happening? Example Article: http://www.knottyboy.com/lore/idx.php/11/183/Maintenance-of-Mature-Locks-6-months-/article/How-do-I-get-sand-out-of-my-dreads.html Example "Print" page: http://www.knottyboy.com/lore/article.php?id=052&action=print

How to 301 multiple domain names to a single domain
Hey, I tried to find and answer to this seemingly simple question, but no luck. So, I have one domain name with a website attached to it. I also registered all the other domain names that are similar to it or have different extensions - I want to redirect all the other domain names to my one main domain name without getting penalised by the big G. It looks like this: www.mainsite.com - this is my main domain I also have www.mainsite.com.au, www.mainsite.org, and www.mainsite.org.au which I all want to just redirect to www.mainsite.com I have been told that the best way to do this is a 301 redirect, but to do that you need to make a CNAME for all the other domains that points to www.mainsite.com. My problem is that I cannot seem to create a CNAME record for http://mainsite.com - I have it working for http://www.mainsite.com but not the non www record. What should I be doing differently? Is it just my DNS provider is useless? Thanks, Anthony

Index forum sites
Hi Moz Team, somehow the last question i raised a few days ago not only wasnt answered up until now, it was also completely deleted and the credit was not "refunded" - obviously there was some data loss involved with your restructuring. Can you check whether you still find the last question and answer it quickly? I need the answer 🙂 Here is one more question: I bought a website that has a huge forum, loads of pages with user generated content. Overall around 500.000 Threads with 9 Million comments. The complete forum is noindex/nofollow when i bought the site, now i am thinking about what is the best way to unleash the potential. The current system is vBulletin 3.6.10. a) Shall i first do an update of vbulletin to version 4 and use the vSEO tool to make the URLs clean, more user and search engine friendly before i switch to index/follow? b) would you recommend to have the forum in the folder structure or on a subdomain? As far as i know subdomain does take lesser strenght from the TLD, however, it is safer because the subdomain is seen as a separate entity from the regular TLD. Having it in he folder makes it easiert to pass strenght from the TLD to the forum, however, it puts my TLD at risk c) Would you release all forum sites at once or section by section? I think section by section looks rather unnatural not only to search engines but also to users, however, i am afraid of blasting more than a millionpages into the index at once. d) Would you index the first page of a threat or all pages of a threat? I fear duplicate content as the different pages of the threat contain different body content but the same Title and possibly the same h1. Looking forward to hear from you soon! Best Fabian
