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."

Is there any benefit to changing 303 redirects to 301?
A year ago I moved my marketplace website from http to https. I implemented some design changes at the same time, and saw a huge drop in traffic that we have not recovered from. I've been searching for reasons for the organic traffic decline and have noticed that the redirects from http to https URLs are 303 redirects. There's little information available about 303 redirects but most articles say they don't pass link juice. Is it worth changing them to 301 redirects now? Are there risks in making such a change a year later, and is it likely to have any benefits for rankings?

Multilingual Site and 301 redirection
Hey there awesome people of Moz I have this site that has many languages in it. The main language is English and my developer did the following www.example.com ( is the main site ) which redirects with a 301 to www.example.com/en if your geo location is supported by our languages then you will automatically be redirected to whatever language you have in your country but does the first language with is english have to 301 redirect to www.example.com/en ? I thought that the right way is to just leave /en at the root file. Thanks in advance

Changing URL structure of date-structured blog with 301 redirects
Howdy Moz, We've recently bought a new domain and we're looking to change over to it. We're also wanting to change our permalink structure. Right now, it's a WordPress site that uses the post date in the URL. As an example: http://blog.mydomain.com/2015/01/09/my-blog-post/ We'd like to use mod_rewrite to change this using regular expressions, to: http://newdomain.com/blog/my-blog-post/ Would this be an appropriate solution? RedirectMatch 301 /./././(.) /blog/$1

Can using nofollow on magento layered navigation hurt?
Howdy Mozzers! We would like to use no follow, no index on our magento layered navigation pages after any two filters are selected. (We are using single filter pages as landing page, so we would liked them indexed) Is it ok to use nofollow, noindex on these filter pages? Are there disadvantages of using nofollow on internal pages? Matt mentioned refraining from using nofollow internally https://www.youtube.com/watch?v=4SAPUx4Beh8 But we would like to conserve crawling bandwidth and PR flow on potentially 100's of thousands of irrelevant/duplicate filter pages.

Old Redirecting Website Still Showing In SERPs
I have a client, a plumber, who bought another plumbing company (and that company's domain) at one point. This other company was very old and has a lot of name recognition so they created a dedicated page to this other company within their main website, and redirected the other company's old domain to that page. This has worked fine, in that this page on the main site is now #1 when you search for the other old company's name. But for some reason the old domain comes up #2 (despite the fact that it's redirecting). Now, I could understand if the redirect had only been set up recently, but I'm reasonably sure this happened about a year ago. Could it be due to the fact that there are many sites out there still linking to that old domain? Thanks in advance!

Any way to find which domains are 301 redirected to competitors' websites?
By looking at the work from an SEO collegue it became clear that his weak linkbuilding graph probably is not the cause for his good rankings for a pretty competitive keyword. (also no social mentions where found) I was wondering what it could be, site structure and other on page optimization factors seems to be ok and I don't think there will be exceptionally good or bad user behavior... Finally I looked at the competitors and found that they have more links, better content en better design, so I got a little stuck. The only reason I can think of is that he is doing 301 redirects (or is rel=canonical tags). Is there a way to trace these redirects back to the source in order to include this important variable in your competitor research? thnx
