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.

Duplicate content and 404 errors
I apologize in advance, but I am an SEO novice and my understanding of code is very limited. Moz has issued a lot (several hundred) of duplicate content and 404 error flags on the ecommerce site my company takes care of. For the duplicate content, some of the pages it says are duplicates don't even seem similar to me. additionally, a lot of them are static pages we embed images of size charts that we use as popups on item pages. it says these issues are high priority but how bad is this? Is this just an issue because if a page has similar content the engine spider won't know which one to index? also, what is the best way to handle these urls bringing back 404 errors? I should probably have a developer look at these issues but I wanted to ask the extremely knowledgeable Moz community before I do 🙂

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,

Best URL-structure for ecommerce store?
What structure will recommend to the product pages? Lets make an example with the keyword "Luxim FZ200" With category in url:
Technical SEO | | gojesper
www.myelectronicshop.com/digital-cameras/luxim-FZ200.html With /product prefix:
www.myelectronicshop.com/product/luxim-FZ200.html Without category in url:
www.myelectronicshop.com/luxim-FZ200.html I have read in a blog post that Paddy Moogan recommend /lluxim-FZ200.html - i think i prefer this version too. But I can see that many of the bigger ecommerce stores are using a /product prefix before the product name. What is the reason for this? and what is best practice?0 -
ECommerce: Best Practice for expired product pages
I'm optimizing a pet supplies site (http://www.qualipet.ch/) and have a question about the best practice for expired product pages. We have thousands of products and hundreds of our offers just exist for a few months. Currently, when a product is no longer available, the site just returns a 404. Now I'm wondering what a better solution could be: 1. When a product disappears, a 301 redirect is established to the category page it in (i.e. leash would redirect to dog accessories). 2. After a product disappers, a customized 404 page appears, listing similar products (but the server returns a 404) I prefer solution 1, but am afraid that having hundreds of new redirects each month might look strange. But then again, returning lots of 404s to search engines is also not the best option. Do you know the best practice for large ecommerce sites where they have hundreds or even thousands of products that appear/disappear on a frequent basis? What should be done with those obsolete URLs?

How to find links to 404 pages?
I know that I used to be able to do this, but I can't seem to remember. One of the sites I am working on has had a lot of pages moving around lately. I am sure some links got lost in the fray that I would like to recover, what is the easiest way to see links going to a domain that are pointing to 404 pages?
