      We're seeing soft 404 errors appear in our google webmaster tools section on pages that are blocked by robots.txt (our search result pages).

      Should we be concerned? Is there anything we can do about this?

        Me too.  It was that video that helped to clear things up for me.  Then I could see when to use robots.txt vs the noindex meta tag.  It has made a big difference in how I manage sites that have large amounts of content that can be sorted in a huge number of ways.

          Good stuff. I was always under the impression they still crawled them (otherwise, how would you know if the block was removed).

            Take a look at

            http://www.youtube.com/watch?v=KBdEwpRQRD0

            to see what I am talking about.

            Robots.txt does prevent crawling according to Matt Cutts.

              Robots.txt prevents indexation, not crawling. The good news is that Googlebot stops crawling 404s.

                Just a couple of under the hood things to check.

                1. Are you sure your robots.txt is setup correctly. Check in GWT to see that Google is reading it.

                2. This may be a timing issue.  Errors take 30-60 days to drop out (as what I have seen) so did they show soft 404 and then you added them to robots.txt?

                If that was the case, this may be a sequence issue.  If Google finds a soft 404 (or some other error) then it comes back to spider and is not able to crawl the page due to robots.txt - it does not know what the current status of the page is so it may just leave the last status that it  found.

                1. I tend to see soft 404 for pages that you have a 301 redirect on where you have a many to one association.  In other words, you have a bunch of pages that are 301ing to a single page.  You may want to consider changing where some of the 301s redirect so that they going to a specific page vs an index page.

                2. If you have a page in robots.txt - you do not want them in Google, here is what I would do.   Show a 200 on that page but then put in the meta tags a noindex nofollow.

                http://support.google.com/webmasters/bin/answer.py?hl=en&answer=93710

                "When we see the noindex meta tag on a page, Google will completely drop the page from our search results, even if other pages link to it"

                Let Google spider it so that it can see the 200 code - you get rid of the soft 404 errors.  Then toss in the noindex nofollow meta tags to have the page removed from the Google index.  It sounds backwards that you have to let Google spider to get it to remove stuff, but it works it you walk through the logic.

                Good luck!

                  Moved company 'Help Center' from Zendesk to Intercom, got lots of 404 errors. What now?

                  Howdy folks, excited to be part of the Moz community after lurking for years! I'm a few weeks into my new job (Digital Marketing at Rewind) and about 10 days ago the product team moved our Help Center from Zendesk to Intercom. Apparently the import went smoothly, but it's caused one problem I'm not really sure how to go about solving: https://help.rewind.io/hc/en-us/articles/***    is where all our articles used to sit https://help.rewind.io/***    is where all our articles now are So, for example, the following article has now moved as such: https://help.rewind.io/hc/en-us/articles/115001902152-Can-I-fast-forward-my-store-after-a-rewind- https://help.rewind.io/general-faqs-and-billing/frequently-asked-questions/can-i-fast-forward-my-store-after-a-rewind This has created a bunch of broken URLs in places like our Shopify/BigCommerce app listings, in our email drips, and in external resources etc. I've played whackamole cleaning many of these up, but these old URLs are still indexed by Google – we're up to 475 Crawl Errors in Search Console over the past week, all of which are 404s. I reached out to Intercom about this to see if they had something in place to help, but they just said my "best option is tracking down old links and setting up 301 redirects for those particular addressed". Browsing the Zendesk forms turned up some relevant-ish results, with the leading recommendation being to configure javascript redirects in the Zendesk document head (thread 1, thread 2, thread 3) of individual articles. I'm comfortable setting up 301 redirects on our website, but I'm in a bit over my head in trying to determine how I could do this with content that's hosted externally and sitting on a subdomain. I have access to our Zendesk admin, so I can go in and edit stuff there, but don't have experience with javascript redirects and have read that they might not be great for such a large scale redirection. Hopefully this is enough context for someone to provide guidance on how you think I should go about fixing things (or if there's even anything for me to do) but please let me know if there's more info I can provide. Thanks!

                  What do you add to your robots.txt on your ecommerce sites?

                  We're looking at expanding our robots.txt, we currently don't have the ability to noindex/nofollow. We're thinking about adding the following: Checkout Basket Then possibly: Price Theme Sortby other misc filters. What do you include?

                  "noindex, follow" or "robots.txt" for thin content pages

                  Does anyone have any testing evidence what is better to use for pages with thin content, yet important pages to keep on a website? I am referring to content shared across multiple websites (such as e-commerce, real estate etc). Imagine a website with 300 high quality pages indexed and 5,000 thin product type pages, which are pages that would not generate relevant search traffic. Question goes: Does the interlinking value achieved by "noindex, follow" outweigh the negative of Google having to crawl all those "noindex" pages? With robots.txt one has Google's crawling focus on just the important pages that are indexed and that may give ranking a boost. Any experiments with insight to this would be great. I do get the story about "make the pages unique", "get customer reviews and comments" etc....but the above question is the important question here.

                  Is it a problem to use a 301 redirect to a 404 error page, instead of serving directly a 404 page?

                  We are building URLs dynamically with apache rewrite.
                  When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page, So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404? Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).

                  Using the same content on different TLD's

                  HI Everyone, We have clients for whom we are going to work with in different countries but sometimes with the same  language. For example we might have a client in a competitive niche working in Germany, Austria and Switzerland (Swiss German) ie we're going to potentially rewrite our website three times in German, We're thinking of using Google's href lang tags and use pretty much the same content - is this a safe option, has anyone actually tries this successfully or otherwise? All answers appreciated. Cheers, Mel.

                  Do search engines crawl links on 404 pages?

                  I'm currently in the process of redesigning my site's 404 page. I know there's all sorts of best practices from UX standpoint but what about search engines? Since these pages are roadblocks in the crawl process, I was wondering if there's a way to help the search engine continue its crawl. Does putting links to "recent posts" or something along those lines allow the bot to continue on its way or does the crawl stop at that point because the 404 HTTP status code is thrown in the header response?

                  Could you use a robots.txt file to disalow a duplicate content page from being crawled?

                  A website has duplicate content pages to make it easier for users to find the information from a couple spots in the site navigation. Site owner would like to keep it this way without hurting SEO. I've thought of using the robots.txt file to disallow search engines from crawling one of the pages. Would you think this is a workable/acceptable solution?

                  NOINDEX listing pages: Page 2, Page 3... etc?

                  Would it be beneficial to NOINDEX category listing pages except for the first page.  For example on this site: http://flyawaysimulation.com/downloads/101/fsx-missions/ Has lots of pages such as Page 2, Page 3, Page 4... etc: http://www.google.com/search?q=site%3Aflyawaysimulation.com+fsx+missions Would there be any SEO benefit of NOINDEX on these pages?  Of course, FOLLOW is default, so links would still be followed and juice applied. Your thoughts and suggestions are much appreciated.
