Hi Roman,
I didn't understand you answer,
Do you know if there is a difference between thousands of 301 redirects that has been done on CDN VS thousands of redirects that has been done in theserver, ( on a website that doesn't use CDN )
Thanks
Roy

YOU DONT HAVE TO WORRY ABOUT IT
If you do not use any redirects, you are serving your content significantly faster. Redirects are likely the one single most time waster in your code especially when you consider mobile networks. They dramatically affect your page speed in a noticeably bad way.
Server-side redirects: Fast, cachable
Common redirects are 301 and 302 redirects which use HTTP to explain that a page or resource has moved. A 301 redirect is permanent and a 302 redirect is temporary. These are both server-side redirects which means that the web server is using HTTP to direct the browser to the new location of the file. Web browser can handle these types of redirect much quicker than client-side redirects and can cache the correct location of the file.Client-side redirects: Slow, not cachable
Redirects that use the http-equiv="refresh" attribute or javascript can introduce even longer waiting times and performance issues and should be not used if at all possible.One of the most used redirects on the web is 301 redirect site wide from the non-www to www version of a webpage. These types of redirects have been recommended for SEO reasons for years so many people have them.
It is my recommendation that if you have this type of redirect, you keep it in as it helps Google understand your website better.
Recommendations from Google
Google suggests eliminating redirects which are not absolutely necessary. They advise redicing redirects by...
- "Never link to a page that you know has a redirect on it. This happens when you have manually created a redirect, but never changed the text link in your HTML to point to the new resource location."
- "Never require more than one redirect to get to any of your resources."

Someone redirected his website to ours
Hi all, I have strange issue as someone redirected website http://bukmachers.pl to ours https://legalnibukmacherzy.pl We don't know exactly what to do with it. I checked backlinks and the website had some links which now redirect to us. I also checked this website on wayback machine and back in 2017 this website had some low quality content but in 2018 they made similar redirection to current one but to different website (our competitor). Can such redirection be harmful for us? Should we do something with this or leave it, as google stop encouraging to disavow low quality links.

Is domain authority lost if you create a 301 redirect but mark it as noindex, nofollow?
Hi everyone, Our company sells products in various divisions. While we've been selling Product A and Product B under our original brand, we've recently created a new division with a new domain to focus on a Product B. The new domain has virtually no domain authority (3) while the original domain has some (37). We want customers to arrive on the new domain when they search for key search terms related to Product B instead of the pages that previously existed on our main website. If we create 301 redirects for the pages and content on the main site and add noindex, nofollow tags, will we lose the domain authority that we have from our original domain because the pages now have the noindex, nofollow tags? I read a few blog posts from Moz that said there isn't any domain authority lost with 301 redirects but I'm not sure if that is true if the pages are noindex, nonofollow. Do you follow? 🙂 Apologies for the lengthy post. Love this community and the great Moz team. Thanks, Joe

301 Redirect from query string to new static page
If i want to create a redirect from a page where the slug ends like this "/?i=4839&mid=1000&id=41537" to a static, more SEO friendly slug like "/contact-us/", will a standard 301 redirect suffice? Thanks, Nails

Can an incorrect 301 redirect or .htaccess code cause 500 errors?
Google Webmaster Tools is showing the following message: _Googlebot couldn't access the contents of this URL because the server had an internal error when trying to process the request. These errors tend to be with the server itself, not with the request. _ Before I contact the person who manages the server and hosting (essentially asking if the error is on his end) is there a chance I could have created an issue with an incorrect 301 redirect or other code added to .htaccess incorrectly? Here is the 301 redirect code I am using in .htaccess: RewriteEngine On RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/.]+/)*(index.html|default.asp)\ HTTP/ RewriteRule ^(([^/.]+/)*)(index|default) http://www.example.com/$1 [R=301,L] RewriteCond %{HTTP_HOST} !^(www.example.com)?$ [NC] RewriteRule (.*) http://www.example.com/$1 [R=301,L] Could adding the following code after that in the .htaccess potentially cause any issues? BEGIN EXPIRES <ifmodule mod_expires.c="">ExpiresActive On

301 redirection pointing to noindexed pages
I have rather an unusual situation where a recently launched affiliate site does not have any unique content as its all syndicated content. For that reason we are currently using the noindex,nofollow meta tags to keep the pages out of the search engines index until we create unique content for the pages. The problem is that due to a very tight timeframe with rebranding, we are looking at 301 redirecting (on a page to page basis) another high authority legacy domain to this new site before we have had a chance to add unique content to it and remove the noindex,nofollow tags. I would assume that any link authority normally passed through the 301 would be lost in this scenario but Im uncertain of what the broader impact might be. Has anyone dealt with a similar scenario? I know this scenario is not ideal and I would rather wait until the unique content is up and noindex tags are removed before launching the 301 redirect of the legacy domain but there are a number of competing priorities at play outside of SEO.

Multiple 301 Redirects for the Same Page
Hi Mozzers, What happens if I have a trail of 301 redirects for the same page? For example,
Intermediate & Advanced SEO | | Travis-W
SiteA.com/10 --> SiteA.com/11 --> SiteA.com/13 --> SiteA.com/14 I know I lose a little bit of link juice by 301 redirecting.
The question is, would the link juice look like this for the example above? 100% --> 90% --> 81% -->72.9%
Or just 100% -----------------------------------------> 90% Does this link juice refer to juice from inbound links or links between internal pages on my site? Thanks!0 -
