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.

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?
Technical SEO | | dkellyagile
-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!0 -
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?
Technical SEO | | twisme
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.1 -
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 🙂

Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?
Dear all, starting with my .htaccess file: RewriteEngine On
Technical SEO | | inlinear
RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html
RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

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 🙂
