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."

How do you 301 redirect URLs with a hashbang (#!) format? We just lost a ton of pagerank because we thought javascript redirect was the only way! But other sites have been able to do this – examples and details inside
Hi Moz, Here's more info on our problem, and thanks for reading! We’re trying to Create 301 redirects for 44 pages on site.com. We’re having trouble 301 redirecting these pages, possibly because they are AJAX and have hashbangs in the URLs. These are locations pages. The old locations URLs are in the following format: www.site.com/locations/#!new-york and the new URLs that we want to redirect to are in this format: www.site.com/locations/new-york We have not been able to create these redirects using Yoast WordPress SEO plugin v.1.5.3.2. The CMS is WordPress version 3.9.1 The reason we want to 301 redirect these pages is because we have created new pages to replace them, and we want to pass pagerank from the old pages to the new. A 301 redirect is the ideal way to pass pagerank. Examples of pages that are able to 301 redirect hashbang URLs include http://www.sherrilltree.com/Saddles#!Saddles and https://twitter.com/#!RobOusbey.

301 redirect subdirectory to new domain
I'm planning on using 301 redirects to spin out a subdirectory of my current website to be its own separate domain. For instance, I currently have a website www.website.com and my writers write tech news at www.website.com/news. Now I want to 301 redirect www.website.com/news to www.technews.com. Will this have any negative impact on SEO? What are some steps that I can take to minimize these impacts?

Is it a problem to use a 301 redirect to a 404 error page, instead of serving directly a 404 page?
We are building URLs dynamically with apache rewrite.
Intermediate & Advanced SEO | | lcourse
When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page, So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404? Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).0 -

Too many 301 redirects?
Hey, My company currently has one chief website with about 500-600 other domains that all feature the same material as the chief website. These domains have been around for about 5 years and have actually picked up some link traffic. I have all of these identical web-pages utilizing rel=canonical but I was wondering if I would be better served, from SEO purposes, to 301 redirect all of these sites to their respective pages on our chief website? If I add 500 301 redirects, will the major search engines consider this to be black-hat link-building even though the sites are related and technically already feature the same content? For an example, the chief website is www.1099pro.com and I would 301 redirect the below sites to the chief site: 1099softwarepro.com 1099softwarepro.info 1099softwarepro.net 1099softwarepro.biz 1099softwareprofessionals.com 1099softwareprofessionals.info ...you get the point

Geoip redirection, 301 or 302?
Hello all Let me first try to explain what our company does and what it is trying to achieve. Our company has an online store, sells products for 3 different countries, and two languages for each country. Currently we have one site, which is open to all countries, what we are trying to achieve is make 3 different stores for these 3 different countries, so we can have a better control over the prices in each country. We are going to use Geoip to redirect the user to the local store in his country. The suggested new structure is to add sub-folders as following: www.example.com/ca-en
Intermediate & Advanced SEO | | ajarad
www.example.com/ca-fr
www.example.com/us-en
... If a visitor is located outside these 3 countries, then she'll be redirected to the root directory www.example.com/en We can't offer to expand our SEO team to optimize new pages for the local market, it's not the priority for now, the main objective now is to be able to control the prices for different market. so to eliminate the duplicate issue, we'll use canonical tags. Now knowing our objective from the new URL structure, I have two questions: 1- which redirect should we use? 301, 302?
If we choose 301, then which version of the site will get the link juice? (i.e, /ca-en or /us-en?)
if we choose 302, then will the link juice remain in the original links? is it healthy to use 302 for long term redirections? 2- Knowing that Google bots comes from US-IP, does that mean that the other versions of the site won't be crawled (i.e, www.example.com/ca-fr), this is especially important for us as we are using AdWords, and unindexed pages will effect our quality score badly. I'd like to know if you have other account structure in your mind that would be better than this proposed structure. Your help is highly highly appreciated.
Thanks in advance.0 -
How to stop Google crawling after 301 redirect?
I have removed all pages from my old website and set 301 redirect to new website. But, I have verified old website with Google webmaster tools' HTML verification file which enable me to track all data and existence of pages in Google search for my old website. I was assumed that, Google will stop crawling and DE-indexed all pages after 301 redirect. Because, I have set 301 redirect before 3 months. Now, I'm able to see Google bot activity on my website with help of Google webmaster tools. You can find out attachment to know more about it. How can it possible & How Google can crawl removed pages? You can see following image to know more about it. First & Second

Can penalties be passed via 301 redirect?
I have a well established domain that's been hit with some penalties. It hasn't been nuked off the map, just downgraded, especially on short-tail, one word type queries. I'm planning on redirecting this domain to another well established domain. The domains already have a history of lots of interlinking and are very similar from a subject matter standpoint. I feel that the penalized domain has been hit with an "over-optimization" of link anchor text penalty (I'm hoping it's algorithmic, but it could be manual). My question is if anyone has ever heard of a penalty like this being transferred to another domain through a 301 redirect. My hope is that the penalty just puts a cap on how much juice the redirect can pass, rather than transferring the penalty to the other domain itself. Any thoughts on this?
