Disallow: /404/ - Best Practice?
-
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.

What do you do with product pages that are no longer used ? Delete/redirect to category/404 etc
We have a store with thousands of active items and thousands of sold items. Each product is unique so only one of each. All products are pinned and pushed online ... and then they sell and we have a product page for a sold item. All products are keyword researched and often can rank well for longtail keywords Would you :- 1. delete the page and let it 404 (we will get thousands) 2. See if the page has a decent PA, incoming links and traffic and if so redirect to a RELEVANT category page ? ~(again there will be thousands) 3. Re use the page for another product - for example a sold ruby ring gets replaces with ta new ruby ring and we use that same page /url for the new item. Gemma

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:
Technical SEO | | hampgunn
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 /Hampus0 -
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.

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

Best Practices for adding Dynamic URL's to XML Sitemap
Hi Guys, I'm working on an ecommerce website with all the product pages using dynamic URL's (we also have a few static pages but there is no issue with them). The products are updated on the site every couple of hours (because we sell out or the special offer expires) and as a result I keep seeing heaps of 404 errors in Google Webmaster tools and am trying to avoid this (if possible). I have already created an XML sitemap for the static pages and am now looking at incorporating the dynamic product pages but am not sure what is the best approach. The URL structure for the products are as follows: http://www.xyz.com/products/product1-is-really-cool
Technical SEO | | seekjobs
http://www.xyz.com/products/product2-is-even-cooler
http://www.xyz.com/products/product3-is-the-coolest Here are 2 approaches I was considering: 1. To just include the dynamic product URLS within the same sitemap as the static URLs using just the following http://www.xyz.com/products/ - This is so spiders have access to the folder the products are in and I don't have to create an automated sitemap for all product OR 2. Create a separate automated sitemap that updates when ever a product is updated and include the change frequency to be hourly - This is so spiders always have as close to be up to date sitemap when they crawl the sitemap I look forward to hearing your thoughts, opinions, suggestions and/or previous experiences with this. Thanks heaps, LW0 -
Is it a problem to have a homepage with a slug / URL ?
Hi, We are designing a web site for one of our clients, and using a home made CMS. I don't know how this CMS has been built, but anyways, in the end the homepage has a URL format which looks like this : www.mydomain.com/my-custom-url.html. No www.mydomain.com. Is it dangerous for SEO to have a slug/URL directly on the homepage ? Do you have experiences, cases where it has impacted a site negatively ? The main problem I expect is duplicate content (with Google seeing both www.mydomain.com and www.mydomain.com/my-custom-url.html as being different pages) but apparently the CMS is doing a 302 redirect from the root domain to the URL (I told my colleague it should at least be a 301). Sorry if this question seems like basic SEO knowledge, but I really can't find a definitive answer on the subject. Thank you very much 🙂

OK to block /js/ folder using robots.txt?
I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1
Technical SEO | | AndreVanKets
http://www.discoverafrica.com/js/jquery.cookie.js?v=1.1
http://www.discoverafrica.com/js/global.js?v=1.2
http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?0 -
What is best practice for redirecting "secondary" domain names?
For sites with multiple top-level domains that have been secured for a business or organization, I'm curious as to what is considered best practice for setting up 301 redirects for secondary domains. Is it best to do the 301 redirects at the registrar level, or the hosting level? So that .net, .biz, or other secondary domains funnel visitors to the correct primary/main domain name. I'm looking for the "best practice" answer and want to avoid duplicate content problems, or penalties from the search engines. I'm not trying to game the system with dozens of domain names, simply the handful of domains that are important to the client. I've seen some registrars recommend hosting secondary domains, and doing redirects from the hosting level (and they use meta refresh for "domain forwarding," which I want to avoid). It seems rather wasteful to set up hosting for a secondary domain and then 301 each URL.
