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.

Our clients Magento 2 site has lots of obsolete categories. Advice on SEO best practice for setting server level redirects so I can delete them?
Our client's Magento website has been running for at least a decade, so has a lot of old legacy categories for Brands they no longer carry. We're looking to trim down the amount of unnecessary URL Redirects in Magento, so my question is: Is there a way that is SEO efficient to setup permanent redirects at a server level (nginx) that Google will crawl to allow us at some point to delete the categories and Magento URL Redirects? If this is a good practice can you at some point then delete the server redirects as google has marked them as permanent?

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 /Hampus0 -
What is the best way to deal with an event calendar
I have an event calendar that has multiple repeating items into the future. They are classes that typically all have the same titles but will occasionally have different information. I don't know what is the best way to deal with them and am open to suggestions. Currently Moz anayltics is showing multiple errors (duplicate page titles, descriptions and overly dynamic urls). I'm assuming that it's showing duplicate elements way into the future. I thought of having the calendar no followed at all but the content for the classes seems valuable. Thanks,

Vanity / Short URLs 301?
Hi everyone, I'm working on a website that uses a lot of short urls eg http://www.forest.com/oaktrees. A quick check reveals these are currently 302 status. My question is should these be made 301s - a lot of them are in off-page content and looking at GA attract a lot of clicks. I've not managed to see a definitive answer to this after several Google searches. All help and advice greatly appreciated. Bw Jon

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

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 -
Redirecting blog.<mydomain>.com to www.<mydomain>.com\blog</mydomain></mydomain>
This is more of a technical question than pure SEO per se, but I am guessing that some folks here may have covered this and so I would appreciate any questions. I am moving from a WordPress.com-based blog (hosted on WordPress) to a WordPress installation on my own server (as suggested by folks in another thread here). As part of this I want to move from the format blog.<mydomain>.com to www.mydomain.com\blog. I have installed WordPress on my server and have imported posts from the hosted site to my own server. How should I manage the transition from first format to the second? I have a bunch of links on Facebook, etc that refer to URLs of the blog..com format so it's important that I redirect.</mydomain> I am running DotNetNuke/WordPress on my own IIS/ASP.Net servers. Thanks. Mark
