404 errors on non-existent URLs
-
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

Google is indexing bad URLS
Hi All, The site I am working on is built on Wordpress. The plugin Revolution Slider was downloaded. While no longer utilized, it still remained on the site for some time. This plugin began creating hundreds of URLs containing nothing but code on the page. I noticed these URLs were being indexed by Google. The URLs follow the structure: www.mysite.com/wp-content/uploads/revslider/templates/this-part-changes/ I have done the following to prevent these URLs from being created & indexed: 1. Added a directive in my Htaccess to 404 all of these URLs 2. Blocked /wp-content/uploads/revslider/ in my robots.txt 3. Manually de-inedex each URL using the GSC tool 4. Deleted the plugin However, new URLs still appear in Google's index, despite being blocked by robots.txt and resolving to a 404. Can anyone suggest any next steps? I Thanks!

Category URL Pagination where URLs don't change between pages
Hello, I am working on an e-commerce site where there are categories with multiple pages. In order to avoid pagination issues I was thinking of using rel=next and rel=prev and cannonical tags. I noticed a site where the URL doesn't change between pages, so whether you're on page 1,2, or 3 of the same category, the URL doesn't change. Would this be a cleaner way of dealing with pagination?

How big is the problem: 404-errors as result of out of stock products?
We had a discussion about the importance of 404-errors as result of products which are out of stock. Of course this is not good, but what is the leverance in terms of importance: low-medium-high?

Expired domain 404 crawl error
I recently purchased a Expired domain from auction and after I started my new site on it, I am noticing 500+ "not found" errors in Google Webmaster Tools, which are generating from the previous owner's contents.Should I use a redirection plugin to redirect those non-exist posts to any new post(s) of my site? or I should use a 301 redirect? or I should leave them just as it is without taking further action? Please advise.

Increase 404 errors or 301 redirects?
Hi all, I'm working on an e-commerce site that sells products that may only be available for a certain period of time. Eg. A product may only be selling for 1 year and then be permanently out of stock. When a product goes out of stock, the page is removed from the site regardless of any links it may have gotten over time. I am trying to figure out the best way to handle these permanently out of stock pages. At the moment, the site is set up to return a 404 page for each of these products. There are currently 600 (and increasing) instances of this appearing on Google Webmasters. I have read that too many 404 errors may have a negative impact on your site, and so thought I might 301 redirect these URLs to a more appropriate page. However I've also read that too many 301 redirects may have a negative impact on your site. I foresee this to be an issue several years down the road when the site has thousands of expired products which will result in thousands of 404 errors or 301 redirects depending on which route I take. Which would be the better route? Is there a better solution?

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

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
