      Hey guys and gals,

      First Moz Q&A for me and really looking forward to being part of the community. I hope as my first question this isn't a stupid one but I was just struggling to find any resource that dealt with the issue and am just looking for some general advice.

      Basically a client has raised a problem with 404 error pages - or the lack thereof- on non-existent URLs on their site; let's say for example: 'greatbeachtowels.com/beach-towels/asdfas'

      Obviously content never existed on this page so its not like you're saying 'hey, sorry this isn't here anymore'; its more like- 'there was never anything here in the first place'. Currently in this fictitious example typing in 'greatbeachtowels.com/beach-towels/asdfas**'** returns the same content as the 'greatbeachtowels.com/beach-towels' page which I appreciate isn't ideal.

      What I was wondering is how far do you take this issue- I've seen examples here on the seomoz site where you can edit the URI in a similar manner and it returns the same content as the parent page but with the alternate address. Should 404's be added across all folders on a site in a similar way? How often would this scenario be and issue particularly for internal pages two or three clicks down? I suppose unless someone linked to a page with a misspelled URL...

      Also would it be worth placing 301 redirects on a small number of common mis-spellings or typos e.g. 'greatbeachtowels.com/beach-towles' to the correct URLs as opposed to just 404s?

      Many thanks in advance.

        Hi Matthew,

        Thanks for the prompt response. Yeah, that's pretty much what I was thinking too- I know its a pretty basic aspect but I just sort of wanted someone to corroborate the process- sorry if it sounded like I was suggesting that just because content never existed there it's a reason not to 404- that wasn't my intention.

        Thanks again

          Hi,

          My understanding of best practices (and what I've always done on sites I've worked on) is that you do want to return a 404 status code on any non-existent URL regardless of whether or not content existed there in the first place. This is your signal to Google/Bing/the world that this is a bad URL. It doesn't matter the reason that URL is broken really, you just want to make sure Google and Bing know that there is no /beach-towels/asdfas page on your site on the off chance they find it or see a link to it.

          If you return the exact same content on /beach-towels/asdfas as you do on /beach-towels/ this does open you up to duplicate content issues because now you have two URLs with the same content. Even though there is a slim chance anybody could discover that an incorrect URL returns duplicate content, you don't want to open yourself to those problems if you can avoid it.

          I do think your idea of common misspelling is a really good one and one not enough people take advantage of. I've implemented 301 redirects for common misspellings on other sites. I've found it is especially helpful on short URLs people are likely to type in by hand (for example, people will type in greatbeachtowels.com/beach so it would be worth making sure greatbeachtowels.com/baech or /beech have a 301 redirect over to that other page.

          Hope some of my answer can help you out. Good luck!

          Thanks,
          Matthew

            Best strategy to handle over 100,000 404 errors.

            I recently been given a site that has over one-hundred thousand 404 error codes listed in Google Webmasters. It is really odd because according to Google Webmasters, the pages that are linking to these 404 pages are also pages that no longer exist (they are 404 pages themselves). These errors were a result of site migration that had occurred. Appreciate any input on how one might go about auditing and repairing large amounts of 404 errors. Thank you.

            Is there a way of changing the Permalink without getting the 404 Error?

            Hi, I am new to this all.. Is there a way of changing the permalink for example from: domain/content/ to domain/profile/ without receiving the 404 error message. It's just that since my website has been developed, some pages and their content have changed but the permalink still shows the name of the old page which may be confusing. Ps. Please use most simple language for explanations as I am really new to it. Thank you! Ve

            Are 404 Errors a bad thing?

            Good Morning... I am trying to clean up my e-commerce site and i created a lot of new categories for my parts... I've made the old category pages (which have had their content removed) "hidden" to anyone who visits the site and starts browsing.  The only way you could get to those "hidden" pages is either by knowing the URLS that I used to use or if for some reason one of them is spidering in Google. Since I'm trying to clean up the site and get rid of any duplicate content issues, would i be better served by adding those "hidden" pages that don't have much or any content to the Robots.txt file or should i just De-activate them so now even if you type the old URL you will get a 404 page... In this case, are 404 pages bad?  You're typically not going to find those pages in the SERPS so the only way you'd land on these 404 pages is to know the old url i was using that has been disabled. Please let me know if you guys think i should be 404'ing them or adding them to Robots.txt Thanks

            Mass 404 Checker?

            Hi all, I'm currently looking after a collection of old newspaper sites that have had various developments during their time. The problem is there are so many 404 pages all over the place and the sites are bleeding link juice everywhere so I'm looking for a tool where I can check a lot of URLs at once. For example from an OSE report I have done a random sampling of the target URLs and some of them 404 (eek!) but there are too many to check manually to know which ones are still live and which ones have 404'd or are redirecting. Is there a tool anyone uses for this or a way one of the SEOMoz tools can do this? Also I've asked a few people personally how to check this and they've suggested Xenu, Xenu won't work as it only checks current site navigation. Thanks in advance!

            Trailing Slashes In Url use Canonical Url or 301 Redirect?

            I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?

            Products with discrete URLs for each color

            here is the issue.  i have an ecommerce site that on a category page, shows each individual color for each product sold.  and there is a distinct URL for each color.  each product page shares the same content, with the only potentially differentiating factor being customer reviews (not nearly enough of these to differentiate anything). so we have URLs like: www.domain.com/product-green www.domain.com/product-yellow www.domain.com/product-red and so on. i am looking for a way to consolidate these URL while still showing all colors on the category page.  the first solution i am considering is using the hash tag.  so we would create www.domain.com/product#green, www.domain.com/product#yellow, www.domain.com/product#red.  if possible, i would set the canonical tag as www.domain.com/product. the second solution would be to use the canonical tag and keep the URLs as is.  the issue i see here is that we would need to create www.domain.com/product and show that page somewhere.  www.domain.com/product would the URL that the above color URLs would canonicalize to. what would be the preferred solution?  or is there something else?

            Should there be a canonical tag on my 404 error page?

            In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.
