Block Domain in robots.txt
-
Hi.
We had some URLs that were indexed in Google from a www1-subdomain. We have now disabled the URLs (returning a 404 - for other reasons we cannot do a redirect from www1 to www) and blocked via robots.txt. But the amount of indexed pages keeps increasing (for 2 weeks now). Unfortunately, I cannot install Webmaster Tools for this subdomain to tell Google to back off...
Any ideas why this could be and whether it's normal?
I can send you more domain infos by personal message if you want to have a look at it.

Hi Philipp,
I have not heard of Google going rogue like this before, however I have seen it with other search engines (Baidu).
I would first verify that the robots.txt is configured correctly, and verify there is no links anywhere to the domain. The reason I mentioned this prior, was due to this official notification on Google: https://support.google.com/webmasters/answer/156449?rd=1
While Google won't crawl or index the content of pages blocked by robots.txt, we may still index the URLs if we find them on other pages on the web. As a result, the URL of the page and, potentially, other publicly available information such as anchor text in links to the site, or the title from the Open Directory Project (www.dmoz.org), can appear in Google search results.
My next thought would be, did Google start crawling the site before the robots.txt blocked them from doing so? This may have caused Google to start the indexing process which is not instantaneous, then you have the new urls appear after the robots.txt went into effect. The solution is add the meta tag noindex, or block put an explicit block on the server as I mention above.
If you are worried about duplicate content issues you maybe able to at least canonical the subdomain urls to the correct url.
Hope that helps and good luck

Hi Don
Thanks for your hint. It doesn't look like there are any links to the www1 subdomain. Also, since we've let the www1-Subdomain return 404's and blocked it with robots, the indexed pages increased from 39'300 to 45'100 so this is more than anybody would link to... Really strange why Google just ignores robots and keeps indexing...

Hi Phil,
Is it possible that google is find the links on another site (like somebody else has your links on their site)? Depending on your situation a good catch all block is to secure the www1 domain with (.htaccess/**.**htpasswd ) this would force anybody (even bots) to provide credentials to see or explore the site. Of course everybody who needs access to the site would have the credentials. So in theory you shouldn't see any more urls getting indexed.
Hope that helps,Don

Thanks for the resource Chris! The strange thing is that Google keeps indexing new URLs even though it is clearly blocked via robots.txt...
But I guess I'll just wait for these 90 days to pass then...

Phillip,
If you've deleted the URLs, there's not much else for you to do. You're experiencing the lag between when Google crawls and indexes pages new pages and when it finds and removes a 404 URL from it's index.
You should think 90 days as an approximate time frame for your page count in the index to start dropping. Here's more from google:

Spammers created bad links to old hacked domain, now redirected to our new domain. Advice?
My client had an old site hacked (let's call it "myolddomain.com") and the hackers created many links in other hacked sites with links such as http://myolddomain.com/styless.asp?jordan-12-taxi-kids-cheap-T8927.html The old myolddomain.com site was redirected to a different new site since then, but we still see over a thousand spam links showing up in the new site's Search Console 404 crawl errors report. Also, using the links: operator in google search, we see many results of spam links. Should we be worried about these bad links pointing to our old site and redirecting to 404s on the new site? What is the best recommendation to clean them up? Ignore? 410s? Other? I'm seeing conflicting advice out there. The old site is hosted by the client's previous web developer who doesn't want to clean anything up on their end without an ongoing hosting contract. So beyond turning redirects on or off, the client doesn't want to pay for any additional hosting. So we don't have much control over anything related to "myolddomain.com". 😞 Thanks in advance for any assistance!

Is sitemap required on my robots.txt?
Hi, I know that linking your sitemap from your robots.txt file is a good practice. Ok, but... may I just send my sitemap to search console and forget about adding ti to my robots.txt? That's my situation: 1 multilang platform which means... ... 2 set of pages. One for each lang, of course But my CMS (magento) only allows me to have 1 robots.txt file So, again: may I have a robots.txt file woth no sitemap AND not suffering any potential SEO loss? Thanks in advance, Juan Vicente Mañanas Abad

Should I block Map pages with robots.txt?
Hello, I have a website that was started in 1999. On the website I have map pages for each of the offices listed on my site, for which there are about 120. Each of the 120 maps is in a whole separate html page. There is no content in the page other than the map. I know all of the offices love having the map pages so I don't want to remove the pages. So, my question is would these pages with no real content be hurting the rankings of the other pages on our site? Therefore, should I block the pages with my robots.txt? Would I also have to remove these pages (in webmaster tools?) from Google for blocking by robots.txt to really work? I appreciate your feedback, thanks!

Blocking Affiliate Links via robots.txt
Hi, I work with a client who has a large affiliate network pointing to their domain which is a large part of their inbound marketing strategy. All of these links point to a subdomain of affiliates.example.com, which then redirects the links through a 301 redirect to the relevant target page for the link. These links have been showing up in Webmaster Tools as top linking domains and also in the latest downloaded links reports. To follow guidelines and ensure that these links aren't counted by Google for either positive or negative impact on the site, we have added a block on the robots.txt of the affiliates.example.com subdomain, blocking search engines from crawling the full subddomain. The robots.txt file is the following code: User-agent: * Disallow: / We have authenticated the subdomain with Google Webmaster Tools and made certain that Google can reach and read the robots.txt file. We know they are being blocked from reading the affiliates subdomain. However, we added this affiliates subdomain block a few weeks ago to the robots.txt, but links are still showing up in the latest downloads report as first being discovered after we added the block. It's been a few weeks already, and we want to make sure that the block was implemented properly and that these links aren't being used to negatively impact the site. Any suggestions or clarification would be helpful - if the subdomain is being blocked for the search engines, why are the search engines following the links and reporting them in the www.example.com subdomain GWMT account as latest links. And if the block is implemented properly, will the total number of links pointing to our site as reported in the links to your site section be reduced, or does this not have an impact on that figure?From a development standpoint, it's a much easier fix for us to adjust the robots.txt file than to change the affiliate linking connection from a 301 to a 302, which is why we decided to go with this option.Any help you can offer will be greatly appreciated.Thanks,Mark

Google insists robots.txt is blocking... but it isn't.
I recently launched a new website. During development, I'd enabled the option in WordPress to prevent search engines from indexing the site. When the site went public (over 24 hours ago), I cleared that option. At that point, I added a specific robots.txt file that only disallowed a couple directories of files. You can view the robots.txt at http://photogeardeals.com/robots.txt Google (via Webmaster tools) is insisting that my robots.txt file contains a "Disallow: /" on line 2 and that it's preventing Google from indexing the site and preventing me from submitting a sitemap. These errors are showing both in the sitemap section of Webmaster tools as well as the Blocked URLs section. Bing's webmaster tools are able to read the site and sitemap just fine. Any idea why Google insists I'm disallowing everything even after telling it to re-fetch?

I accidentally blocked Google with Robots.txt. What next?
Last week I uploaded my site and forgot to remove the robots.txt file with this text: User-agent: * Disallow: / I dropped from page 11 on my main keywords to past page 50. I caught it 2-3 days later and have now fixed it. I re-imported my site map with Webmaster Tools and I also did a Fetch as Google through Webmaster Tools. I tweeted out my URL to hopefully get Google to crawl it faster too. Webmaster Tools no longer says that the site is experiencing outages, but when I look at my blocked URLs it still says 249 are blocked. That's actually gone up since I made the fix. In the Google search results, it still no longer has my page title and the description still says "A description for this result is not available because of this site's robots.txt – learn more." How will this affect me long-term? When will I recover my rankings? Is there anything else I can do? Thanks for your input! www.decalsforthewall.com

Internal search : rel=canonical vs noindex vs robots.txt
Hi everyone, I have a website with a lot of internal search results pages indexed. I'm not asking if they should be indexed or not, I know they should not according to Google's guidelines. And they make a bunch of duplicated pages so I want to solve this problem. The thing is, if I noindex them, the site is gonna lose a non-negligible chunk of traffic : nearly 13% according to google analytics !!! I thought of blocking them in robots.txt. This solution would not keep them out of the index. But the pages appearing in GG SERPS would then look empty (no title, no description), thus their CTR would plummet and I would lose a bit of traffic too... The last idea I had was to use a rel=canonical tag pointing to the original search page (that is empty, without results), but it would probably have the same effect as noindexing them, wouldn't it ? (never tried so I'm not sure of this) Of course I did some research on the subject, but each of my finding recommanded one of the 3 methods only ! One even recommanded noindex+robots.txt block which is stupid because the noindex would then be useless... Is there somebody who can tell me which option is the best to keep this traffic ? Thanks a million

Robots.txt and canonical tag
In the SEOmoz post - http://www.seomoz.org/blog/robot-access-indexation-restriction-techniques-avoiding-conflicts, it's being said - If you have a robots.txt disallow in place for a page, the canonical tag will never be seen. Does it so happen that if a page is disallowed by robots.txt, spiders DO NOT read the html code ?
