How to handle a blog subdomain on the main sitemap and robots file?
-
Hi,
I have some confusion about how our blog subdomain is handled in our sitemap. We have our main website, example.com, and our blog, blog.example.com.
-
Should we list the blog subdomain URL in our main sitemap? In other words, is listing a subdomain allowed in the root sitemap?
-
What does the final structure look like in terms of the sitemap and robots file? Specifically:
would I include a link to our blog subdomain (blog.example.com)?
would I include a link to BOTH our main sitemap and blog sitemap?
would I include a link to our main website URL (even though it's not a subdomain)?
does a subdomain need its own robots file?
I'm a technical SEO and understand the mechanics of much of on-page SEO.... but for some reason I never found an answer to this specific question and I am wondering how the pros do it. I appreciate your help with this.

It's my understanding that you treat each subdomain as a unique site. So each subdomain should have its own unique XML sitemap and robots.txt file, as well as submitted separately to Google Webmaster Tools. But to answer your inter-linking question, I would avoid including the other domain URLs in those files (XML and Robots). Only include the URLs for that particular domain and/or subdomain. With that being said however, I would inter-link them on the actual site somewhere. Maybe in the HTML sitemap, navigation, footer, or even naturally throughout your body content where appropriate as well.

Subdomain cannibalization
Hi, I am doing the SEO for a webshop, which has a lot of linking and related websites on the same root domain. So the structure is for example: Root domain: example.com
Intermediate & Advanced SEO | | Mat_C
Shop: shop.example.com
Linking websites to shop: courses.example.com, software.example.com,... Do I have to check which keywords these linking websites are already ranking for and choose other keywords for my category and product pages on the webshop? The problem with this could be that the main keywords for the category pages on the webshop are mainly the same as for the other subdomains. The intention is that some people immediately come to the webshop instead of going first to the linking websites and then to the webshop. Thanks.0 -
Dev Subdomain Pages Indexed - How to Remove
I own a website (domain.com) and used the subdomain "dev.domain.com" while adding a new section to the site (as a development link). I forgot to block the dev.domain.com in my robots file, and google indexed all of the dev pages (around 100 of them). I blocked the site (dev.domain.com) in robots, and then proceeded to just delete the entire subdomain altogether. It's been about a week now and I still see the subdomain pages indexed on Google. How do I get these pages removed from Google? Are they causing duplicate content/title issues, or does Google know that it's a development subdomain and it's just taking time for them to recognize that I deleted it already?

Blog comments - backlinks - question
Hi, I see that many good websites have backlinks from very good blogs/sites which are relative. What I noticed that everyone use their real name or generic name in comments. They do not use the keyword for the name. So later they get backlinks with anchor text of their names... So, my question is this good technique ? Do I have any benefits from these backlinks for my website ? With such a technique, whether it is enough just to leave your real name or may I periodically put the keyword for the name ? Thank you

Is Using a Question, Answer Format Appropriate for a Blog? Is a 300 Word Micro Blog An SEO Plus?
My PR agency has suggested a question answer format be incorporated in my blog. They suggest a microblog with a single sentence question and an answer of about 300 words. My blog currently has about 35 posts. I would like to ramp up blog entries to about one or two per week of these "mini blog" posts. The format of the new blog begins as a question with the responses being paragraphs that do not use headings. My concerns are as follows: 1. No headings in an answer of 300 words will fail to provide Google with context regarding the content's meaning. Everything I have read about SEO suggests text be broken up in short sections and that it be divided by headings (preferably H2s). I very much like my agency's concept for a question answer format blog. It provides very practical info for visitors. How can I use it in a manner that supports SEO best practices? 2. According to a reputable SEO firm that has been assisting me, Google does not consider a blog post of less than 600 words to be superior quality. They told me that blog posts of 300 words, from an SEO purpose will not be a great helpful, that the content will not be rich enough to generate incoming links. Is this really the case? What if this abbreviated content is very well written and engaging? If so, is 300 words sufficient? From the visitor's perspective I am not sure they would have the patience to read 600 words when 300 words is more than than enough to answer these basic questions. From a PR perspective I think the shorter content in a question answer format is superior at least for my line of business (commercial real estate brokerage). 3. If 500-600 words is the minimum word count, and headings are necessary, what is the best way to execute a question and answer blog format? The purpose of this blog is to provide very useful info to my visitors while generating incoming links to that will boast my rankings. Thanks in advance for your feedback!!! Alan

How do I list the subdomains of a domain?
Hi Mozers, I am trying to find what subdomains are currently active on a particular domain. Is there a way to get a list of this information? The only way I could think of doing it is to run a google search on; site:example.com -site:www.example.com The only issues with this approach is that a majority of the indexed pages exist on the non-www domain and I still have thousands of pages in the results (mainly from the non-www). Is there another way to do it in Google? OR is there a server admin online tool that will tell me this information? Cheers, Dan

Use of subdomains, subdirectories or both?
Hello, i would like your advice on a dilemma i am facing. I am working a new project that is going to release soon, thats a network of users with personal profiles seperated in categories for example lets say the categories are colors. So let say i am a member and i belong in red color categorie and i got a page where i update my personal information/cv/resume as well as a personal blog thats on that page. So the main site is giving the option to user to search for members by the criteria of color. My first idea is that all users should own a subdomain (and this is how its developed so far) thats easy to use and since the domain name is really small (just 3 letters) i believe subdomain worth since personal site will be easy to remember. My dilemma is should all users own a subdomain, a subdirectory or both and if both witch one should be the canonical? Since it said that search engines treat subdomains as different stand-alone sites, whats best for the main site? to show multiple search results with profiles in subdomains or subdirectories? What if i use both? meaning in search results i use search directory url for each profile while same time each profile owns a subdomains as well? and if so which one should be the canonical? Thanks in advance, C
