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.

How to create a smooth blog migration from subdomain to subfolder main?
Hi mozzers, We have decided to migrate the blog subdomain to the domain's subfolder (blog.example.com to example.com/blog). To do this the most effective way and avoid impact SEO negatively I believe I have to follow this checklist: Create a list of all 301 redirects from blog.example.com/post-1 to example.com/post-1 Make sure title tags remain the same on main domain Make sure internal links remain the same Is there something else I am missing? Any other best practices? I also would like to have all blog post as AMPs. Any recommendations if this something we should do since we are not a media site? Any other tips on successfully implementing those types of pages? Thanks

URL structure change and xml sitemap
At the end of April we changed the url structure of most of our pages and 301 redirected the old pages to the new ones. The xml sitemaps were also updated at that point to reflect the new url structure. Since then Google has not indexed the new urls from our xml sitemaps and I am unsure of why. We are at 4 weeks since the change, so I would have thought they would have indexed the pages by now. Any ideas on what I should check to make sure pages are indexed?

Blog subdomain not redirecting
Over the last few weeks I have been focused on fixing high and medium priority issues, as reported by the Moz crawler, after a recent transition to WordPress. I've made great progress, getting the high priority issues down from several hundred (various reasons, but many duplicates for things like non-www and www versions) to just five last week. And then there's this weeks report. For reasons I can't fathom, I am suddenly getting hundreds of duplicate content pages of the form http://blog.<domain>.com</domain> (being duplicates with the http://www.<domain>.com</domain> versions). I'm really unclear on why these suddenly appeared. I host my own WordPress site ie WordPress.org stuff. In Options / General everything refers to http://www.<domain>.com</domain> and has done for a number of weeks. I have no idea why the blog versions of the pages have suddenly appeared. FWIW, the non-www version of my pages still redirect to the www version, as I would expect. I'm obviously pretty concerned by this so any pointers greatly appreciated. Thanks. Mark

Hreflang in vs. sitemap?
Hi all, I decided to identify alternate language pages of my site via sitemap to save our development team some time. I also like the idea of having leaner markup. However, my site has many alternate language and country page variations, so after creating a sitemap that includes mostly tier 1 and tier 2 level URLs, i now have a sitemap file that's 17mb. I did a couple google searches to see is sitemap file size can ever be an issue and found a discussion or two that suggested keeping the size small and a really old article that recommended keeping it < 10mb. Does the sitemap file size matter? GWT has verified the sitemap and appears to be indexing the URLs fine. Are there any particular benefits to specifying alternate versions of a URL in vs. sitemap? Thanks, -Eugene

Turning off a subdomain
Hi! I'm currently working with http://www.muchbetteradventures.com/. They have a previous version of the site, http://v1.muchbetteradventures.com, as sub domain on their site. I've noticed a whole bunch of indexing issues which I think are caused by this. The v1 site has several thousand pages and ranks organically for a number of terms, but the pages are not relevant for the business at this time. The main site has just over 100 pages. More than 28,400 urls are currently indexed. We are considering turning off the v1 site and noindexing it. There are no real backlinks to it. The only worry is that by removing it, it will be seen as a massive drop in content. Rankings for the main site are currently quite poor, despite good content, a decent link profile and high domain authority. Any thoughts would be much appreciated!
