      Hello Moz Community,

      My developer has added this to my robots.txt file: Disallow: /404/

      Is this considered good practice in the world of SEO? Would you do it with your clients?

      I feel he has great development knowledge but isn't too well versed in SEO.

      Thank you in advanced,

      Nico.

          This comes down to personal preference in my opinion. I think honestly it is neither here nor there. The instances that your 404 page could come up in the SERP's is more than likely pretty low and at the same time it really does not offer any useful content. So disallowing it would not really be any loss. One reason why it might be disallowed is that you have an e-commerce site that rotates products. When a product is deleted, the developer has a 301 to the 404 page, then with the robots.txt saying not to index the 404 page, the other page will drop out of search engines. If this is the case I would rethink that strategy. If you notice a lot of sites like amazon and other big sites leave the page in the index even if the product is no longer for sale. The thought is traffic is traffic, the hardest part in the whole equation is getting someone to your site, if the page is ranking, why delete it.

          The only time I can think that I would specifically allow it and optimize it is if you have a cool 404 page. Some companies actually spend a bit of time on their pages and it gets them a little pop of viral traffic from social sharing sites like reddit. If you do have one that is funny or unique I would allow it and actually optimize it for a term like "funny 404 page" or something like that.

            Topic Cluster: URL Best Practices

            I'm trying to be mature and employ the Topic Cluster strategy to my content. In doing so I realized there are a few URL options. Some more difficult to execute than others. -Is it important to call out the Pillar Topic in your subtopic URL?
            -Does the Pillar Topic need to have its own landing page? (As opposed to just being part of the blog.) Here's an Example: My Pillar is: Inbound vs. Outbound
            My subtopic is: Marketing Platforms Here are the URL options I can think of... Option 1: https://pipelineinbound.com/blog/inbound-vs-outbound-marketing-platforms/ Option 2: https://pipelineinbound.com/blog/which-marketing-platforms/ Option 3: https://pipelineinbound.com/blog/marketing-platforms-inbound-vs-outbound/ Option 4 (Hardest): https://pipelineinbound.com/inbound-vs-outbound/marketing-platforms/ Are there some fundamental best practices for URL structure and Link Building as it pertains to Topic Clusters? Thanks!

            What is SEO best practice to implement a site logo as an SVG?

            What is SEO best practice to implement a site logo as an SVG?
            Since it is possible to implement a description for SVGs it seems that it would be possible to use that for the site name. <desc>sitename</desc>
                {{ STUFF }} There is also a title tag for SVGs. I’ve read in a thread from 2015 that sometimes it gets confused with the title tag in the header (at least by Moz crawler) which might cause trouble. What is state of the art here? Any experiences and/or case studies with using either method? <title>sitename</title>
                {{ STUFF }} However, to me it seems either way that best practice in terms of search engines being able to crawl is to load the SVG and implement a proper alt tag: What is your opinion about this? Thanks in advance.

            SEO advice on ecommerce url structure where categories contain "/c/"

            Hi! We use Hybris as plattform and I would like input on which url to choose. We must keep "/c/" before the actual category. c stands for category. I.e. this current url format will be shortened and cleaned:
            https://www.granngarden.se/Sortiment/Husdjur/Hund/Hundfoder-%26-Hundmat/c/hundfoder To either: a. 
            https://www.granngarden.se/husdjur/hund/hundfoder/c/hundfoder b.
            https://www.granngarden.se/husdjur/hund/c/hundfoder (hundfoder means dogfood) The question is whether we should keep the duplicated category name (hundfoder) before the "/c/" or not. Will there be SEO disadvantages by removing the duplicate "hundfoder" before the "/c/"? I prefer the shorter version ofc, but do not want to jeopardize any SEO rankings or send confusing signals to search engines or customers due to the "/c/" breaking up the url breadcrumb. What do you guys say and prefer from the above alternatives? Thanks /Hampus

            Image Height/Width attributes, how important are they and should a best practice site include this as std

            Hi How important are the image height/width attributes and would you expect a best practice site to have them included ? I hear not having them can slow down a page load time is that correct ? Any other issues from not having them ? I know some re social sharing (i know bufferapp prefers images with h/w attributes to draw into their selection of image options when you post) Most importantly though would you expect them to be intrinsic to sites that have been designed according to best practice guidelines ? Thanks

            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?

            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

            Location Based Content / Googlebot

            Our website has local content specialized to specific cities and states. The url structure of this content is as follows: www.root.com/seattle www.root.com/washington When a user comes to a page, we are auto-detecting their IP and sending them directly to the relevant location based page - much the way that Yelp does. Unfortunately, what appears to be occurring is that Google comes in to our site from one of its data centers such as San Jose and is being routed to the San Jose page. When a user does a search for relevant keywords, in the SERPS they are being sent to the location pages that it appears that bots are coming in from. If we turn off the auto geo, we think that Google might crawl our site better, but users would then be show less relevant content on landing. What's the win/win situation here? Also - we also appear to have some odd location/destination pages ranking high in the SERPS. In other words, locations that don't appear to be from one of Google's data center. No idea why this might be happening. Suggestions?
