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!

One robots.txt file for multiple sites?
I have 2 sites hosted with Blue Host and was told to put the robots.txt in the root folder and just use the one robots.txt for both sites. Is this right? It seems wrong. I want to block certain things on one site. Thanks for the help, Rena

Two META Robots tags on a page - which will win?
Hi, Does anybody know which meta-robots tag will "win" if there is more than one on a page? The situation:
Technical SEO | | jmueller
our CMS is not very flexible and so we have segments of META-Tags on the page that originate from templates.
Now any author can add any meta-tag from within his article-editor.
The logic delivering the pages does not care if there might be more than one meta-robots tag present (one from template, one from within the article). Now we could end up with something like this: Which one will be regarded by google & co?
First?
Last?
None? Thanks a lot,

Best Way To Clean Up Unruly SubDomain?
Hi, I have several subdomains that present no real SEO value, but are being indexed. They don't earn any backlinks either. What's the best way of cleaning them up? I was thinking the following: 1. Verify them all in Webmaster Tools. 2. Remove all URLs from the index via the Removal Tool in WMT 3. Add site-wide no-index, follow directive. Also, to remove the URLs in WMT, you usually have to block the URLs via /robots.txt. If I'd like to keep Google crawling through the subdomains and remove their URLs, is there a way to do so?

Robots.txt to disallow /index.php/ path
Hi SEOmoz, I have a problem with my Joomla site (yeah - me too!). I get a large amount of /index.php/ urls despite using a program to handle these issues. The URLs cause indexation errors with google (404). Now, I fixed this issue once before, but the problem persist. So I thought, instead of wasting more time, couldnt I just disallow all paths containing /index.php/ ?. I don't use that extension, but would it cause me any problems from an SEO perspective? How do I disallow all index.php's? Is it a simple: Disallow: /index.php/

OK to block /js/ folder using robots.txt?
I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1

http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?0 -
Subdomain and Domain Rankings
I have read here that domain names with keywords might add a boost to your search rank For instance using a completely inane example monkey-fights.com might get a boost compared to mfl.com (monkey fighting league) when searching for "monkey fights" There seems to be a hot debate as to how much bonus the first domain might get over the second, but leaving that aside for the moment. Question 1. Would monkey-fights.mfl.com get the same kind of bonus as a root domain bonus? Question 2. If the answer to 1 above was yes would a 301 redirect from the suddomain URL to root domain URL retain that bonus I was just thinking on how hard it is to get root domains these days that are not either being squatted on etc. and if this might be a way to get the same bonus, or maybe subdomains are less bonus prone and so it would be a waste of time Thanks
