      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!

                  404 Errors flaring on nonexistent or unpublished pages – should we be concerned for SEO?

                  Hello! We keep getting "critical crawler" notifications on Moz because of firing 404 codes. We've checked each page and know that we are not linking to them anywhere on our site, they are not published and they are not indexed on Google. It's only happened since we migrated our blog to Hubspot so we think it has something to do with the test pages their developers had set up and that they are just lingering in our code somewhere. However, we are still concerned having these codes fire implies negative consequences for our SEO. Is this the case? Should we be concerned about these 404 codes despite the pages from those URLs not actually existing? Thank you!
                  Chloe

                  Should I Add Location to ALL of My Client's URLs?

                  Hi Mozzers, My first Moz post! Yay! I'm excited to join the squad 🙂 My client is a full service entertainment company serving the Washington DC Metro area (DC, MD & VA) and offers a host of services for those wishing to throw events/parties. Think DJs for weddings, cool photo booths, ballroom lighting etc. I'm wondering what the right URL structure should be. I've noticed that some of our competitors do put DC area keywords in their URLs, but with the moves of SERPs to focus a lot more on quality over keyword density, I'm wondering if we should focus on location based keywords in traditional areas on page (e.g. title tags, headers, metas, content etc) instead of having keywords in the URLs alongside the traditional areas I just mentioned. So, on every product related page should we do something like: example.com/weddings/planners-washington-dc-md-va
                  example.com/weddings/djs-washington-dc-md-va
                  example.com/weddings/ballroom-lighting-washington-dc-md-va OR example.com/weddings/planners
                  example.com/weddings/djs
                  example.com/weddings/ballroom-lighting In both cases, we'd put the necessary location based keywords in the proper places on-page. If we follow the location-in-URL tactic, we'd use DC area terms in all subsequent product page URLs as well. Essentially, every page outside of the home page would have a location in it. Thoughts? Thank you!!

                  Why some websites can rank the keywords they don't have in the page?

                  Hello guys, Yesterday, I used SEMrush to search for the keyword "branding agency" to see the SERP. The Liquidagency ranks 5th on the first page. So I went to their homepage but saw no exact keywords "branding agency", even in the page source. Also, I didn't see "branding agency" as a top anchor text in the external links to the page (from the report of SEMrush). I am an SEO newbie, can someone explain this to me, please? Thank you.

                  Should I use meta noindex and robots.txt disallow?

                  Hi, we have an alternate "list view" version of every one of our search results pages The list view has its own URL, indicated by a URL parameter I'm concerned about wasting our crawl budget on all these list view pages, which effectively doubles the amount of pages that need crawling When they were first launched, I had the noindex meta tag be placed on all list view pages, but I'm concerned that they are still being crawled Should I therefore go ahead and also apply a robots.txt disallow on that parameter to ensure that no crawling occurs? Or, will Googlebot/Bingbot also stop crawling that page over time? I assume that noindex still means "crawl"... Thanks 🙂

                  What's the deal with significantLinks?

                  http://schema.org/significantLink Schema.org has a definition for "non-navigation links that are clicked on the most." Presumably this means something like the big green buttons on Moz's homepage. But does anyone know how they affect anything? In http://moz.com/blog/schemaorg-a-new-approach-to-structured-data-for-seo#comment-142936, Jeremy Nelson says " It's quite possible that significant links will pass anchor text as well if a previous link to the page was set in navigation, effictively making obselete the first-link-counts rule, and I am interested in putting that to test." This is a pretty obscure comment but it's one of the only results I could find on the subject. Is this BS? I can't even make out what all of it is saying. So what's the deal with significantLinks and how can we use them to SEO?

                  Do you add 404 page into robot file or just add no index tag?

                  Hi, got different opinion on this so i wanted to double check with your comment is. We've got /404.html page and I was wondering if you would add this page to robot text so it wouldn't be indexed or would you just add no index tag? What would be the best approach? Thanks!
