          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

                Does anyone know the linking of hashtags on Wix sites does it negatively or positively impact SEO.  It is coming up as an error in site crawls 'Pages with 404 errors'  Anyone got any experience please? For example at the bottom of this blog post https://www.poppyandperle.com/post/face-painting-a-global-language the hashtags are linked, but they don't go to a page, they go to search results of all other blogs using that hashtag.  Seems a bit of a strange approach to me.

                Errors In Search Console

                Hi All, I am hoping someone might be able to help with this. Last week one of my sites dropped from mid first day to bottom of page 1. We had not been link building as such and it only seems to of affected a single search term and the ranking page (which happens to be the home page). When I was going through everything I went to search console and in crawl errors there are 2 errors that showed up as detected 3 days before the drop. These are: wp-admin/admin-ajax.php showing as response code 400 and also xmlrpc.php showing as response code 405 robots.txt is as follows: user-agent: * disallow: /wp-admin/ allow: /wp-admin/admin-ajax.php Any help with what is wrong here and how to fix it would be greatly appreciated. Many Thanks

                Hundreds of 404 errors are showing up for pages that never existed

                For our site, Google is suddenly reporting hundreds of 404 errors, but the pages they are reporting never existed. The links Google shows are clearly spam style,  but the website hasn't been hacked. This happened a few weeks ago, and after a couple days they disappeared from WMT. What's the deal?

                URL - Well Formed or Malformed

                Hi Mozzers, I've been mulling over whether my URLs could benefit a little SEO tweaking. I'd be grateful for your opinion. For instance, we've a product, a vintage (second hand), red Chanel bag. At the moment the URL is: www.vintageheirloom.com/vintage-chanel-bags/2.55-bags/red-2.55-classic-double-flap-bag-1362483150 Broken down... vintage-chanel-bags = this is the main product category, i.e. vintage chanel bags 2.55-bags = is a sub category of the main category above. They are vintage Chanel 2.55 bags, but I've not included 'vintage' again. 2.55 bags are a type of Chanel bag. red-2.55-classic-double-flap-bag = this is the product, the bag **1362483150 **= this is a unique id, to prevent the possibility of duplicate URLs As you no doubt can see we target, in particular, the phrase **vintage. **The actual bag / product title is: Vintage Chanel Red 2.55 classic double flap bag 10” / 25cm With this in mind, would I be better off trying to match the product name with the end of the URL as closely as possible? So a close match below would involve not repeating 'chanel' again: www.vintageheirloom.com/chanel-bags/2.55-bags/vintage-red-2.55-classic-double-flap-bag or an exact match below would involve repeating 'chanel': www.vintageheirloom.com/chanel-bags/2.55-bags/vintage-chanel-red-2.55-classic-double-flap-bag This may open up more flexibility to experiment with product terms like second hand, preowned etc. Maybe this is a bad idea as I'm removing the phrase 'vintage' from the main category. But this logical extension of this looks like keyword stuffing !! www.vintageheirloom.com/vintage-chanel-bags/vintage-2.55-bags/vintage-chanel-red-2.55-classic-double-flap-bag Maybe this is over analyzing, but I doubt it? Thanks for looking. Kevin

                404 error - but I can't find any broken links on the referrer pages

                Hi, My crawl has diagnosed a client's site with eight 404 errors. In my CSV download of the crawl, I have checked the source code of the 'referrer' pages, but can't find where the link to the 404 error page is. Could there be another reason for getting 404 errors? Thanks for your help. Katharine.

                404 Errors After Site Migration

                Hello - I'm working on a website selling fashion accessories.  The site just went through a site migration from Yahoo! to Big Commerce.  Now we have a high level of warnings and errors from the crawl.  Few are mentioning sites I never seen before on the Yahoo! platform. I also notice that the pages crawled has doubled.  How can I fix or did I do something wrong with migration? I was running the website with minimal errors and now overwhelmed with errors all the error updates.  If I can get some assistance on what could be wrong, I would greatly appreciate. Thanks.

                Should me URLs be uppercase or lowercase

                I'm in the middle of doing a bunch of 301 redirects for me site. Should I make them Lowercase, uppercase, or does it matter? Also, do I want to be using hyphens (-), or underscores (_)? Any other tips? EX: http://www.stupid.com/golf-slippers.html OR http://www.stupid.com/Golf-Slippers.html
