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 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 -
Best Practice on 301 Redirect - Images
We have two sites that sell the same products. We have decided to retire one of the sites as we'd like to focus on one property. I know best practice is to redirect apples to apples, which in our case is easily done since the sites sold the same thing. www.SiteABC.com/ProductA can be redirected to www.SiteXYZ.com/ProductA. My question is how far does that thinking go regarding images? Each product has a main product page, of course, and then up to 6 images in some cases. Is it necessary to redirect www.SiteABC.com/ProductA-Image1.jpg to www.SiteXYZ.com/ProductA-Image1.jpg? Or can they all be redirected to just the product page?

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! 🙂

Best Way To Clean Up Unruly SubDomain?
Hi, I have several subdomains that present no real SEO value, but are being indexed. They don't earn any backlinks either. What's the best way of cleaning them up? I was thinking the following: 1. Verify them all in Webmaster Tools. 2. Remove all URLs from the index via the Removal Tool in WMT 3. Add site-wide no-index, follow directive. Also, to remove the URLs in WMT, you usually have to block the URLs via /robots.txt. If I'd like to keep Google crawling through the subdomains and remove their URLs, is there a way to do so?

Googlebot does not obey robots.txt disallow
Hi Mozzers! We are trying to get Googlebot to steer away from our internal search results pages by adding a parameter "nocrawl=1" to facet/filter links and then robots.txt disallow all URLs containing that parameter. We implemented this late august and since that, the GWMT message "Googlebot found an extremely high number of URLs on your site", stopped coming. But today we received yet another. The weird thing is that Google gives many of our nowadays robots.txt disallowed URLs as examples of URLs that may cause us problems. What could be the reason? Best regards, Martin

Cloaking? Best Practices Crawling Content Behind Login Box
Hi- I'm helping out a client, who publishes sale information (fashion sales etc.) In order for the client to view the sale details (date, percentage off etc.) they need to register for the site. If I allow google bot to crawl the content, (identify the user agent) but serve up a registration light box to anyone who isn't google would this be considered cloaking? Does anyone know what the best practice for this is? Any help would be greatly appreciated. Thank you, Nopadon

How does Google find /feed/ at the end of all pages on my site?
Hi! In Google Webmaster Tools I find *.../feed/ as a 404 page in crawl errors. The problem is that none of these pages exist and they have no inbound links (except the start page). FYI, it´s a wordpress site. Example: www.mysite.com/subpage1/feed/ www.mysite.com/subpage2/feed/ www.mysite.com/subpage3/feed/ etc Does Google search for /feed/ by default or why do I keep getting these 404´s every day?

What is the best method to block a sub-domain, e.g. staging.domain.com/ from getting indexed?
Now that Google considers subdomains as part of the TLD I'm a little leery of testing robots.txt with something like: staging.domain.com
Technical SEO | | fthead9
User-agent: *
Disallow: / in fear it might get the www.domain.com blocked as well. Has anyone had any success using robots.txt to block sub-domains? I know I could add a meta robots tag to the staging.domain.com pages but that would require a lot more work.0
