      Hi,

      I have some old pages that were coming up in google WMT as a 404.  These had links into them so i thought i'd do a 301 back to either the home page or to a relevant category or page.

      However these are now listed in WMT as soft 404's.

      I'm not sure what this means and whether google is saying it doesn't like this?

      Any advice welcomed.

        Hi Jeff,

        I had the same issue with a client last year. In a nut shell a soft 404 error is when the page looks like a regular 404 error web page but the http response header returns 200 OK. So search engines think that the page is okay (a regular webpage) but there is no content on that page etc.

        Your webteam will need to identify how they are producing the soft 404 error pages (with 200OK header responses) and change that set-up in the CMS. Or, if these are old pages that are no longer required and are no longer driving traffic then archive/delete them.

        Good luck,
        Davinia

          Hi Jeff,

          I'll take a snippit from the webmaster tools

          "In addition to returning a 404 code in response to a request for a page that doesn’t exist, the server will also display a 404 page. This may be a standard "File Not Found" message, or it could be a custom page designed to provide the user with additional information. The content of the page is entirely unrelated to the HTTP response returned by the server. Just because a page displays a 404 File Not Found message doesn’t mean that it’s a 404 page. It's like a giraffe wearing a name tag that says "dog." Just because it says it's a dog, doesn't mean it's actually a dog. Similarly, just because a page says 404, doesn't mean it's returning a 404. You can use Fetch as Google (or other tools available on the web) to verify whether the URL is actually returning the correct code."

          and to help here is another link

          http://forums.seochat.com/search-engine-optimization-28/diff-between-404-soft-404-error-467526.html

          "The error 404 "page not found" means that the page you are finding server can't find he page.
          Soft 404 means page not found and user will move to either home page or custom page."

          Hope it helps.

            Site structure: Any issues with 404'd parent folders?

            Is there any issue with a 404'd parent folder in a URL? There's no links to the parent folder and a parent folder page never existed. For example say I have the following pages w/ content: /famous-dogs/lassie/
            /famous-dogs/snoopy/
            /famous-dogs/scooby-doo/ But I never (and maybe never plan to) created a general **/famous-dogs/ **page. Sitemaps.xml does not link to it, nor does any page on my site. Is there any concerns with doing this? Am I missing out on any sort of value that might pass to a parent folder?

            Changed all external links to 'NoFollow' to fix manual action penalty. How do we get back?

            I have a blog that received a Webmaster Tools message about a guidelines violation because of "unnatural outbound links" back in August. We added a plugin to make all external links 'NoFollow' links and Google removed the penalty fairly quickly. My question, how do we start changing links to 'follow' again? Or at least being able to add 'follow' links in posts going forward? I'm confused by the penalty because the blog has literally never done anything SEO-related, they have done everything via social and email. I only started working with them recently to help with their organic presence. We don't want them to hurt themselves at all, but 'follow' links are more NATURAL than having everything as 'NoFollow' links, and it helps with their own SEO by having clean external 'follow' links. Not sure if there is a perfect answer to this question because it is Google we're dealing with here, but I'm hoping someone else has some tips that I may not have thought about. Thanks!

            Ranking 1st for a keyword - but when 's' is added to the end we are ranking on the second page

            Hi everyone - hope you are well. I can't get my head around why we are ranking 1st for a specific keyword, but then when 's' is added to the end of the keyword - we are ranking on the second page. What could be the cause of this? I thought that Google would class both of the keywords the same, in this case, let's say the keyword was 'button'. We would be ranking 1st for 'button', but 'buttons' we are ranking on the second page. Any ideas? - I appreciate every comment.

            Pipe ("|") in my website's title is being replaced with ":" in Google results

            Hi , One of the websites I'm promoting and working on is www.pau-brasil.co.il.
            It's wordpress-based website and as you can see the html's Title is "PauBrasil | some hebrew slogan".
            (Screenshot: http://i.imgur.com/2f80EEY.gif)
            When I'm searching for "PauBrasil" (Which is the brand's name) , one of the results google shows is "PauBrasil: Some Hebrew Slogan" (Screenshot: http://i.imgur.com/eJxNHrO.gif ) Why does the pipe is being replaced with ":" ?
            And not just that , as you can see there's a "blank space" missing between the the ":" to the slogan.
            (note: the websites has been indexed by google crawler at least 4 times so I find it hard to believe it can be the reason) I've keep on looking and found out that there's another page in that website with the exact same title
            but when I'm looking for it in google , it shows the title as it really is , with pipe. ("|").
            (Screenshot: http://i.imgur.com/dtsbZV2.gif) Have you ever encountered something like that?
            Can it be that the duplicated title cause that weird "replacement"? Thanks in advance,
            Kadel

            Do I need to use canonicals if I will be using 301's?

            I just took a job about three months and one of the first things I wanted to do was restructure the site. The current structure is solution based but I am moving it toward a product focus. The problem I'm having is the CMS I'm using isn't the greatest (and yes I've brought this up to my CMS provider). It creates multiple URL's for the same page. For example, these two urls are the same page: (note: these aren't the actual urls, I just made them up for demonstration purposes) http://www.website.com/home/meet-us/team-leaders/boss-man/
            http://www.website.com/home/meet-us/team-leaders/boss-man/bossman.cmsx (I know this is terrible, and once our contract is up we'll be looking at a different provider) So clearly I need to set up canonical tags for the last two pages that look like this: http://www.omnipress.com/boss-man" /> With the new site restructure, do I need to put a canonical tag on the second page to tell the search engine that it's the same as the first, since I'll be changing the category it's in? For Example: http://www.website.com/home/meet-us/team-leaders/boss-man/ will become http://www.website.com/home/MEET-OUR-TEAM/team-leaders/boss-man My overall question is, do I need to spend the time to run through our entire site and do canonical tags AND 301 redirects to the new page, or can I just simply redirect both of them to the new page? I hope this makes sense. Your help is greatly appreciated!!

            How to check a website's architecture?

            Hello everyone, I am an SEO analyst - a good one - but I am weak in technical aspects. I do not know any programming and only a little HTML. I know this is a major weakness for an SEO so my first request to you all is to guide me how to learn HTML and some basic PHP programming. Secondly... about the topic of this particular question - I know that a website should have a flat architecture... but I do not know how to find out if a website's architecture is flat or not, good or bad. Please help me out on this... I would be obliged. Eagerly awaiting your responses, BEst Regards, Talha

            External 404 vs Internal 404

            Which one is bad? External - when someone adds an incorrect link to your site, maybe does a typo when linking to an inner page. This page never existed on your site, google shows this as a 404 in Webmaster tools. Internal - a page existed, google indexed it, and you deleted it and didnt add a 301. Internal ones are in the webmaster's control, and i can understand if google gets upset if it sees a 404 for a URL that existed before, however surely "externally created" 404 shoudnt cause any harm cause that page never existed. And someone has inserted an incorrect link to your site.
