      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!

                  Schema markup concerning category pages on an ecommerce site

                  We are adding json+ld data to an ecommerce site and myself and one of the other people working on the site are having a minor disagreement on things. What it comes down to is how to mark up the category page. One of us says it needs to be marked up with as an Itempage, https://schema.org/ItemPage  The other says it needs to be marked up as products, with multiple product instances in the schema, https://schema.org/Product The main sticking point on the Itemlist is that Itemlist is a child of intangible, so there is a feeling that should be used for things like track listings or other arbitrary data.

                  Will disallowing URL's in the robots.txt file stop those URL's being indexed by Google

                  I found a lot of duplicate title tags showing in Google Webmaster Tools. When I visited the URL's that these duplicates belonged to, I found that they were just images from a gallery that we didn't particularly want Google to index. There is no benefit to the end user in these image pages being indexed in Google. Our developer has told us that these urls are created by a module and are not "real" pages in the CMS. They would like to add the following to our robots.txt file Disallow: /catalog/product/gallery/ QUESTION: If the these pages are already indexed by Google, will this adjustment to the robots.txt file help to remove the pages from the index? We don't want these pages to be found.

                  Remove URLs that 301 Redirect from Google's Index

                  I'm working with a client who has 301 redirected thousands of URLs from their primary subdomain to a new subdomain (these are unimportant pages with regards to link equity). These URLs are still appearing in Google's results under the primary domain, rather than the new subdomain. This is problematic because it's creating an artificial index bloat issue. These URLs make up over 90% of the URLs indexed. My experience has been that URLs that have been 301 redirected are removed from the index over time and replaced by the new destination URL. But it has been several months, close to a year even, and they're still in the index. Any recommendations on how to speed up the process of removing the 301 redirected URLs from Google's index? Will Google, or any search engine for that matter, process a noindex meta tag if the URL's been redirected?

                  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?

                  Robots.txt, does it need preceding directory structure?

                  Do you need the entire preceding path in robots.txt for it to match? e.g: I know if i add Disallow: /fish to robots.txt it will block /fish
                  /fish.html
                  /fish/salmon.html
                  /fishheads
                  /fishheads/yummy.html
                  /fish.php?id=anything But would it block?: en/fish
                  en/fish.html
                  en/fish/salmon.html
                  en/fishheads
                  en/fishheads/yummy.html
                  **en/fish.php?id=anything (taken from Robots.txt Specifications)** I'm hoping it actually wont match, that way writing this particular robots.txt will be much easier! As basically I'm wanting to block many URL that have BTS- in such as: http://www.example.com/BTS-something
                  http://www.example.com/BTS-somethingelse
                  http://www.example.com/BTS-thingybob But have other pages that I do not want blocked, in subfolders that also have BTS- in, such as: http://www.example.com/somesubfolder/BTS-thingy
                  http://www.example.com/anothersubfolder/BTS-otherthingy Thanks for listening

                  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?

                  Using 2 wildcards in the robots.txt file

                  I have a URL string which I don't want to be indexed. it includes the characters _Q1 ni the middle of the string. So in the robots.txt can I use 2 wildcards in the string to take out all of the URLs with that in it?  So something like /_Q1.  Will that pickup and block every  URL with those characters in the string? Also, this is not directly of the root, but in a secondary directory, so .com/.../_Q1.  So do I have to format the robots.txt as //_Q1* as it will be in the second folder or just using /_Q1 will pickup everything no matter what folder it is on? Thanks.

                  There's a website I'm working with that has a .php extension. All the pages do. What's the best practice to remove the .php extension across all pages?

                  Client wishes to drop the .php extension on all their pages (they've got around 2k pages). I assured them that wasn't necessary. However, in the event that I do end up doing this what's the best practices way (and easiest way) to do this? This is also a WordPress site. Thanks.
