Robots.txt on subdomains
-
Hi guys!
I keep reading conflicting information on this and it's left me a little unsure. Am I right in thinking that a website with a subdomain of shop.sitetitle.com will share the same robots.txt file as the root domain?
-
That's about as comprehensive an answer as I could have hoped for. Thanks Ryan, really appreciated.

Mostly no. I say 'mostly' because a lot of times when you look at a site using www and no-www if both of those work they're almost always pulling files from the same location (hence the warnings around duplicate content), so both www.domain.com/robots.txt and domain.com/robots.txt are going to work. This is the dominant example of a subdomain sharing a robots.txt file. However, on domains that are set up as their own subdomains they have different robots.txt. Take a look at the many differences between subdomain1-1000.wordpress.com/robots.txt vs wordpress.com/robots.txt. If you set up a subdomain that isn't just a reflection of your root domain, then you'll need to create a robots.txt file as well. Cheers!

Google Indexed a version of my site w/ MX record subdomain
We're doing a site audit and found "internal" links to a page in search console that appear to be from a subdomain of our site based on our MX record. We use Google Mail internally. The links ultimately redirect to our correct preferred subdomain "www", but I am concerned as to why this is happening and if it can have any negative SEO implications. Example of one of the links: Links aspmx3.googlemail.com.sullivansolarpower.com/about/solar-power-blog/daniel-sullivan/renewable-energy-and-electric-cars-are-not-political-footballs I did a site operator search, site:aspmx3.googlemail.com.sullivansolarpower.com on google and it returns several results.

Images, CSS and Javascript on subdomain or external website
Hi guy's, I came across webshops that put images, CSS and Javascript on different websites or subdomains. Does this boost SEO results? On our Wordpress webshop all the sourcescodes are placed after our own domainname: www.ourdomainname.com/wp-includes/js/jquery/jquery.js?ver=1.11.3'

Subdomain as News Section instead of Source in Google News?
Hi, trying to dig into Google News for a large site, mostly containing news.
Technical SEO | | m.m
The structure of the site network is subdomain.domain.se, and each subdomain has it's own brand with it's own news: x.domain.se
y.domain.se
z.domain.se
etc... Each brand/subdomain is more or less to equate with its own subjectfield/section. In Google News every subdomain is configured with it's own Site Source url, but also having the set up with one section with the same url. It seems like they're getting conflicts in Google News, Google can't always figure out which news article to which brand. Example: an article owned by brand A, but it is sometimes happens that articles getting labeled as brand B in the news SERP, though the link takes you correctly to brand A. I am thinking that this config in News Publisher Center may be a problem? Anyone having any thoughts if that would be better if we delete all source urls except for domain.se-brand and then put all the other subdomains as sections? www.domain.se x.domain.se y.doamin.se z.domain.se Any smart thoughts on this one? Or anything else that could make this wrong labeling (all content included images are hosted in same domain for example). Regards,

Is sitemap required on my robots.txt?
Hi, I know that linking your sitemap from your robots.txt file is a good practice. Ok, but... may I just send my sitemap to search console and forget about adding ti to my robots.txt? That's my situation: 1 multilang platform which means... ... 2 set of pages. One for each lang, of course But my CMS (magento) only allows me to have 1 robots.txt file So, again: may I have a robots.txt file woth no sitemap AND not suffering any potential SEO loss? Thanks in advance, Juan Vicente Mañanas Abad

Staging & Development areas should be not indexable (i.e. no followed/no index in meta robots etc)
Hi I take it if theres a staging or development area on a subdomain for a site, who's content is hence usually duplicate then this should not be indexable i.e. (no-indexed & nofollowed in metarobots) ? In order to prevent dupe content probs as well as non project related people seeing work in progress or finding accidentally in search engine listings ? Also if theres no such info in meta robots is there any other way it may have been made non-indexable, or at least dupe content prob removed by canonicalising the page to the equivalent page on the live site ? In the case in question i am finding it listed in serps when i search for the staging/dev area url, so i presume this needs urgent attention ? Cheers Dan

"Fourth-level" subdomains. Any negative impact compared with regular "third-level" subdomains?
Hey moz New client has a site that uses: subdomains ("third-level" stuff like location.business.com) and; "fourth-level" subdomains (location.parent.business.com) Are these fourth-level addresses at risk of being treated differently than the other subdomains? Screaming Frog, for example, doesn't return these fourth-level addresses when doing a crawl for business.com except in the External tab. But maybe I'm just configuring the crawls incorrectly. These addresses rank, but I'm worried that we're losing some link juice along the way. Any thoughts would be appreciated!

Should we move our documentation off subdomain?
Background: We have a popular open source e-commerce platform at http://spreecommerce.com. Right now the documentation is on http://guides.spreecommerce.com. We have "edge" documentation (for stuff that's not yet released) on http://edgeguides.spreecommerce.com but since it's largely duplicative we've told google not to index any of the edge stuff (via robots.txt). Question: Should we consider moving the guides under the main website under /docs or something like this? There's a ton of great content that people often read to learn more about the platform. Seems like we might be diluting our juice a bit to have it on a separate domain. WDYT?

Best geotargeting strategy: Subdomains or subfolders or country specific domain
How have the relatively recent changes in how G perceives subdomains changed the best route to onsite geotargeting i.e. not building out new country specific sites on country specific and hosted domains and instead developing sub-domains or sub-folders and geo-targeting those via webmaster tools ? In other words, given the recent change in G perception, are sub-domains now a better option than a sub-folder or is there not much in it ? Also if client has a .co.uk and they want to geo-target say France, is the sub-domain/sub-folder route still an option or is the .co.uk still too UK specific, and these options would only work using a .com ? In other words can sites on country specific domains (.co.uk , .fr, .de etc etc) use sub-folders or domains to geo-target other countries or do they have no option other than to develop new country specific (domains/hosting/language) websites ? Any thoughts regarding current best practice in this regard much appreciated. I have seen last Febs WBF which covers geotargeting in depth but the way google perceives subdomains has changed since then Many Thanks Dan
