No index on subdomains
-
Hi,
We have a subdomain that is appearing in the search results - I want to hide this as it looks really bad. If I were to add the no index tag to the sub domain would URL would this affect the whole domain or just that sub domain?
The main domain is vitally important - it is just that sub domain I need to hide.
Many thanks

Andy and Alan covered what you need to do. One more thing to keep in mind, check the traffic, you don't want to lose those spot in the SERPS. You might want to consider fixing up the subdomain if it gets you conversions and traffic.

does the root domain link to the subdomain?
if so then noindex,follow the pages in the subdomain, this will allow link juice to flow back out of the subdomain.
any links pointing to a nofollow page will waste their link juice -
Hi Nicholas,
You are fine noindexing the subdomain. However, you will need to create a new robots.txt file and place it in the subdomain root for it to work.

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!

Homepage not indexed - seems to defy explanation
Hey folks Hoping to get some more eyes on a specific problem I am seeing with a clients site. Site: http:www.ukjuicers.com We have checked everything we can think of and the usual suspects here are not present: Canonical URL is in place Site is shown as indexed in search console No Crawl, DNS, Connectivity or server errors No robots.txt blocking - verified in search console No robots meta tags or directives Fetch as Google works Fetch & render works site command returns all other pages info command does not return the homepage homepage is cached and cache has been updated since this issue started: http://webcache.googleusercontent.com/search?q=cache:www.ukjuicers.com homepage is indexed in yahoo and Bing all variations redirect to the www.ukjuicers.com domain (.co.uk, .com, www, sans www etc) The only issue I found after some extensive digging was some issues with the HTTP and HTTPS versions of the site both being available and both specifying the canonical version as themselves. So, http site used canonicals with http and https site used canonicals with https. So, a conflict there with the canonical exacerbating the problem it is there to solve. The HTTPS site is not indexed though and we have set this up in webmaster tools and now the web developer has set redirects to ensure all versions even the https now 301 redirect to the http://www.ukjuicers.com page so these canonical issues have been ironed out. But... it's still not indexing the homepage. The practical implications of this are quite scary - the site used to be somewhere between 1st and 4th for keywords like 'juicers', 'juicer' etc. Now they are bottom of page 1 or top of page 2 with an internal page. They were jostling with the big boys (amazon, argos, john lewis etc) but now they are right at the bottom of the second page. It's a strange one - i have seen all manor of technical problems over the years but this one seems to defy sensible explanation. The next step is to do a full technical SEO audit of the site but I am always of the opinion that with many eyes all bugs are shallow so if anyone has any input or experience with odd indexation problems like this would love to get your input. Cheers

De-indexing millions of pages - would this work?
Hi all, We run an e-commerce site with a catalogue of around 5 million products. Unfortunately, we have let Googlebot crawl and index tens of millions of search URLs, the majority of which are very thin of content or duplicates of other URLs. In short: we are in deep. Our bloated Google-index is hampering our real content to rank; Googlebot does not bother crawling our real content (product pages specifically) and hammers the life out of our servers. Since having Googlebot crawl and de-index tens of millions of old URLs would probably take years (?), my plan is this: 301 redirect all old SERP URLs to a new SERP URL. If new URL should not be indexed, add meta robots noindex tag on new URL. When it is evident that Google has indexed most "high quality" new URLs, robots.txt disallow crawling of old SERP URLs. Then directory style remove all old SERP URLs in GWT URL Removal Tool This would be an example of an old URL:

www.site.com/cgi-bin/weirdapplicationname.cgi?word=bmw&what=1.2&how=2 This would be an example of a new URL:
www.site.com/search?q=bmw&category=cars&color=blue I have to specific questions: Would Google both de-index the old URL and not index the new URL after 301 redirecting the old URL to the new URL (which is noindexed) as described in point 2 above? What risks are associated with removing tens of millions of URLs directory style in GWT URL Removal Tool? I have done this before but then I removed "only" some useless 50 000 "add to cart"-URLs.Google says themselves that you should not remove duplicate/thin content this way and that using this tool tools this way "may cause problems for your site". And yes, these tens of millions of SERP URLs is a result of a faceted navigation/search function let loose all to long.
And no, we cannot wait for Googlebot to crawl all these millions of URLs in order to discover the 301. By then we would be out of business. Best regards,

Exact match subdomains
Hi, I have seen significant SEO benefits from owning exact match domains and was wondering whether exact match subdomains hold the same (or some) of these benefits? eg. halloweencostumes.co.uk vs. halloween [dot] costumes.co.uk Many thanks.

Why google index my IP URL
hi guys, a question please. if site:112.65.247.14 , you can see google index our website IP address, this could duplicate with our darwinmarketing.com content pages. i am not quite sure why google index my IP pages while index domain pages, i understand this could because of backlink, internal link and etc, but i don't see obvious issues there, also i have submit request to google team to remove ip address index, but seems no luck. Please do you have any other suggestion on this? i was trying to do change of address setting in Google Webmaster Tools, but didn't allow as it said "Restricted to root level domains only", any ideas? Thank you! boson

Index forum sites
Hi Moz Team, somehow the last question i raised a few days ago not only wasnt answered up until now, it was also completely deleted and the credit was not "refunded" - obviously there was some data loss involved with your restructuring. Can you check whether you still find the last question and answer it quickly? I need the answer 🙂 Here is one more question: I bought a website that has a huge forum, loads of pages with user generated content. Overall around 500.000 Threads with 9 Million comments. The complete forum is noindex/nofollow when i bought the site, now i am thinking about what is the best way to unleash the potential. The current system is vBulletin 3.6.10. a) Shall i first do an update of vbulletin to version 4 and use the vSEO tool to make the URLs clean, more user and search engine friendly before i switch to index/follow? b) would you recommend to have the forum in the folder structure or on a subdomain? As far as i know subdomain does take lesser strenght from the TLD, however, it is safer because the subdomain is seen as a separate entity from the regular TLD. Having it in he folder makes it easiert to pass strenght from the TLD to the forum, however, it puts my TLD at risk c) Would you release all forum sites at once or section by section? I think section by section looks rather unnatural not only to search engines but also to users, however, i am afraid of blasting more than a millionpages into the index at once. d) Would you index the first page of a threat or all pages of a threat? I fear duplicate content as the different pages of the threat contain different body content but the same Title and possibly the same h1. Looking forward to hear from you soon! Best Fabian
