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!

Robots.txt allows wp-admin/admin-ajax.php
Hello, Mozzers!
Technical SEO | | AndyKubrin
I noticed something peculiar in the robots.txt used by one of my clients: Allow: /wp-admin/admin-ajax.php What would be the purpose of allowing a search engine to crawl this file?
Is it OK? Should I do something about it?
Everything else on /wp-admin/ is disallowed.
Thanks in advance for your help.

Role of Robots.txt and Search Console parameters settings
Hi, wondering if anyone can point me to resources or explain the difference between these two. If a site has url parameters disallowed in Robots.txt is it redundant to edit settings in Search Console parameters to anything other than "Let Googlebot Decide"?

Robots txt. in page with 301 redirect
We currently have a a series of help pages that we would like to disallow from our robots txt. The thing is that these help pages are located in our old website, which now has a 301 redirect to current site. Which is the proper way to go around? 1- Add the pages we want to disallow to the robots.txt of the new website? 2- Break the redirect momentarily and add the pages to the robots.txt of the old one? Thanks

Does an subdomain hosted offsite provide SEO value
We have a job board hosted through an applicant processing system which we've setup as a subdomain (jobs.ourcompany.com), most of the assets are hosted on our primary domain (ourcompany.com). My question is does having it hosted offsite provide any value? Do we get credit for that content being shared and distributed on the web or does the applicant processing system? As I see it the options are (correct me if I'm wrong): Host the job listings on our primary domain (ourcompany.com/jobs) and have it point to the application on the subdomain. Advertise the job listings pointing to the primary domain on the paid sites. The free job listing sites will automatically point to the sub-domain because the applicant processing system automatically submits them. Host the job listings entirely on the sub-domain applicant tracking system and link to it from our primary site navigation. Advertise the job listings to the sub-domain so that both free and paid point to the same place. Obviously the second one would be much easier just not sure on the technical side of our website getting credit by search engines as the one who has produced the content.

Are robots.txt wildcards still valid? If so, what is the proper syntax for setting this up?
I've got several URL's that I need to disallow in my robots.txt file. For example, I've got several documents that I don't want indexed and filters that are getting flagged as duplicate content. Rather than typing in thousands of URL's I was hoping that wildcards were still valid.

Empty Meta Robots Directive - Harmful?
Hi, We had a coding update and a side-effect of that was that our directive was emptied, in other words it now reads as: on all of the site. I've since noticed that Google's cache date on all of the pages - at least, the ones I tested - have a Cached date of no later than 17 December '12 - that's the Monday after the directive was removed on mass. So, A, does anyone have solid evidence of an empty directive causing problems? Past experience, Matt Cutts, Fishkin quote, etc. And then B - It seems fairly well correlated but, does my entire site's homogenous Cached date point to this tag removal? Or is it fairly normal to have a particular cache date across a large site (we're a large ecommerce site). Our site: http://www.zando.co.za/ I'm having the directive reinstated as soon as Dev permitting. And then, for extra credit, is there a way with Google's API, or perhaps some other tool, to run an arbitrary list and retrieve Cached dates? I'd want to do this for diagnosis purposes and preferably in a way that OK with Google. I'd avoid CURLing for the cached URL and scraping out that dates with BASH, or any such kind of thing. Cheers,

Should I block robots from URLs containing query strings?
I'm about to block off all URLs that have a query string using robots.txt. They're mostly URLs with coremetrics tags and other referrer info. I figured that search engines don't need to see these as they're always better off with the original URL. Might there be any downside to this that I need to consider? Appreciate your help / experiences on this one. Thanks Jenni

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
