Disallow indexing of ALL subdomains

[conversal]

I'm using www.domain.com as my development hosting. Each website that i'm developing get's a temporary URL like this:

project1.domain.com
project2.domain.com
project3.domain.com
...

Now i'd like to set that ALL these subdomains can not be indexed in Google. Now I manually have to do this for each subdomain's site, and when I go online I have to change the robots.txt again. So I would like to make things a bit easier for me.

Is this possible?

You should edit your .htaccess file as is described here:

I hope i answered your question

Thanks for the link, but I don't think that will solve my problem?

When Google wants to crawl project1.domain.com, he won't check the .htaccess of domain.com right? So then he'll just be crawling that subdomain?

Nobody?

Hello there!

Like Wesley mentioned before the best way to avoid any "non-desired" crawling and indexing of your development or testing environment is by requiring authentication (whether with htaccess or your own programmed login/password screen).

Unfortunately sometimes there have been situations when search crawlers don't necessarily follow robots.txt directives. Additionally, beyond search engines you might want to protect your development or testing environment, making sure that only people with the required access to it can enter. Because of this, the best way to go is requiring authentication to access to your subdomains, not robots.txt.

I hope this help!
