What is the best method to block a sub-domain, e.g. staging.domain.com/ from getting indexed?
-
Now that Google considers subdomains as part of the TLD I'm a little leery of testing robots.txt with something like:
staging.domain.com
User-agent: *
Disallow: /in fear it might get the www.domain.com blocked as well. Has anyone had any success using robots.txt to block sub-domains? I know I could add a meta robots tag to the staging.domain.com pages but that would require a lot more work.
-
Just make sure that when/if you copy over the staging site to the live domain that you don't copy over the robots.txt, htaccess, or whatever means you use to block that site from being indexed and thus have your shiny new site be blocked.
-
I agree. The name of your subdomain being "staging" didn't register at all with me until Matt brought it up. I was offering a generic response to the subdomain question whereas I believe Matt focused on how to handle a staging site. Interesting viewpoint.
-
Matt/Ryan-
Great discussion, thanks for the input. The staging.domain.com is just one of the domains we don't want indexed. Some of them still need to be accessed by the public, some like staging could be restricted to specific IPs.
I realize after your discussion I probably should have used a different example of a sub-domain. On the other hand it might not have sparked the discussion so maybe it was a good example
-
.htaccess files can be placed at any directory level of a site so you can do it for just the subdomain or even just a directory of a domain.
-
Staging URL's are typically only used for testing so rather than do a deny I would recommend using a specific ALLOW for only the IP addresses that should be allowed access.
I would imagine you don't want it indexed because you don't want the rest of the world knowing about it.
You can also use HTACCESS to use username/passwords. It is simple but you can give that to clients if that is a concern/need.
-
Correct.
-
Toren, I would not recommend that solution. There is nothing to prevent Googlebot from crawling your site via almost any IP. If you found 100 IPs used by the crawler and blocked them all, there is nothing to stop the crawler from using IP #101 next month. Once the subdomain's content is located and indexed, it will be a headache fixing the issue.
The best solution is always going to be a noindex meta tag on the pages you do not wish to be indexed. If that method is too much work or otherwise undesirable, you can use the robots.txt solution. There is no circumstance I can imagine where you would modify your htaccess file to block googlebot.
-
Hi Matt.
Perhaps I misunderstood the question but I believe Toren only wishes to prevent the subdomain from being indexed. If you restrict subdomain access by IP it would prevent visitors from accessing the content which I don't believe is the goal.
-
Interesting, hadn't thought of using htaccess to block Googlebot.Thanks for the suggestion.
-
Thanks Ryan. So you don't see any issues with de-indexing the main site if I created a second robots.txt file, e.g.
http://staging.domin.com/robots.txt
User-agent: *
Disallow: /That was my initial thought but when Google announced they consider sub-domains part of the TLD I was afraid it might affect the htp://www.domain.com versions of the pages. So you're saying the subdomain is basically treated like a folder you block on the primary domain?
-
Use an .htaccess file to only allow from certain ip addresses or ranges.
Here is an article describing how: http://www.kirupa.com/html5/htaccess_tricks.htm

What is the best method to block a sub-domain, e.g. staging.domain.com/ from getting indexed?
Place a robots.txt file in the root of the subdomain.
User-agent: *
Disallow: /This method will block the subdomain while leaving your primary domain unaffected.

URLs dropping from index (Crawled, currently not indexed)
I've noticed that some of our URLs have recently dropped completely out of Google's index. When carrying out a URL inspection in GSC, it comes up with 'Crawled, currently not indexed'. Strangely, I've also noticed that under referring page it says 'None detected', which is definitely not the case. I wonder if it could be something to do with the following? https://www.seroundtable.com/google-ranking-index-drop-30192.html - It seems to be a bug affecting quite a few people. Here are a few examples of the URLs that have gone missing: https://www.ihasco.co.uk/courses/detail/sexual-harassment-awareness-training https://www.ihasco.co.uk/courses/detail/conflict-resolution-training https://www.ihasco.co.uk/courses/detail/prevent-duty-training Any help here would be massively appreciated!

Multiple CMS on one website / domain & SEO
For a client we would like to work with a content hub, but their website is build on a custom CMS so we are limited in our options and if we aks their web developers they ask crazy prices to help us. So now we have the idea to build the content hub with wordpress and implement it next to their current CMS. for example on www.website.com/contenthub/ . As far as i know this is technically possible and there are no negative effects regarding SEO as long as we link the two sitemaps together. Am i right or am i missing something here?

What are best options for website built with navigation drop-down menus in JavaScript, to get those menus indexed by Google?
This concerns f5.com, a large website with navigation menus that drop down when hovered over. The sub nav items (example: “DDoS Protection”) are not cached by Google and therefore do not distribute internal links properly to help those sub-pages rank well. Best option naturally is to change the nav menus from JS to CSS but barring that, is there another option? Will Schema SiteNavigationElement work as an alternate?

How to block "print" pages from indexing
I have a fairly large FAQ section and every article has a "print" button. Unfortunately, this is creating a page for every article which is muddying up the index - especially on my own site using Google Custom Search. Can you recommend a way to block this from happening? Example Article: http://www.knottyboy.com/lore/idx.php/11/183/Maintenance-of-Mature-Locks-6-months-/article/How-do-I-get-sand-out-of-my-dreads.html Example "Print" page: http://www.knottyboy.com/lore/article.php?id=052&action=print

What is best practice for redirecting "secondary" domain names?
For sites with multiple top-level domains that have been secured for a business or organization, I'm curious as to what is considered best practice for setting up 301 redirects for secondary domains. Is it best to do the 301 redirects at the registrar level, or the hosting level? So that .net, .biz, or other secondary domains funnel visitors to the correct primary/main domain name. I'm looking for the "best practice" answer and want to avoid duplicate content problems, or penalties from the search engines. I'm not trying to game the system with dozens of domain names, simply the handful of domains that are important to the client. I've seen some registrars recommend hosting secondary domains, and doing redirects from the hosting level (and they use meta refresh for "domain forwarding," which I want to avoid). It seems rather wasteful to set up hosting for a secondary domain and then 301 each URL.

How do I redirect index.html to the root / ?
The site I've inherited had operated on index.html at one point, and now uses index.php for the home page, which goes to the / page. The index.html was lost in migrating server hosts. How do I redirect the index.html to the / page? I've tried different options that keep giving ending up with the same 404 error. I tried a redirect from index.html to index.php which ended in an infinite loop. Because the index.html no longer exists in the root, should I created it and then add a redirect to it? Can I avoid this by editing the .htaccess? Any help is appreciated, thanks in advance!

How to 301 multiple domain names to a single domain
Hey, I tried to find and answer to this seemingly simple question, but no luck. So, I have one domain name with a website attached to it. I also registered all the other domain names that are similar to it or have different extensions - I want to redirect all the other domain names to my one main domain name without getting penalised by the big G. It looks like this: www.mainsite.com - this is my main domain I also have www.mainsite.com.au, www.mainsite.org, and www.mainsite.org.au which I all want to just redirect to www.mainsite.com I have been told that the best way to do this is a 301 redirect, but to do that you need to make a CNAME for all the other domains that points to www.mainsite.com. My problem is that I cannot seem to create a CNAME record for http://mainsite.com - I have it working for http://www.mainsite.com but not the non www record. What should I be doing differently? Is it just my DNS provider is useless? Thanks, Anthony
