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."

New Site (redesign) Launched Without 301 Redirects to New Pages - Too Late to Add Redirects?
We recently launched a redesign/redevelopment of a site but failed to put 301 redirects in place for the old URL's. It's been about 2 months. Is it too late to even bother worrying about it at this point? The site has seen a notable decrease in site traffic/visits, perhaps due to this issue. I assume that once the search engines get an error on a URL, it will remove it from displaying in search results after a period of time. I'm just not sure if they will try to re-crawl those old URLs at some point and if so, it may be worth it to have those 301 redirects in place. Thank you.

SEO impact difference between a URL Rewrite and 301 redirect
Hi guys and girls! Just putting a new site live, we changed the URL from one thing to another and I created a 301 file redirecting the urls like for like. The developer installing it has created a different file with columns like: RewriteRule ^page/ http://www.site/page [R=301,L] RewriteRule ^/page/ http://www.site/page [R=301,L] What's the difference? The page redirects but is there a difference between the 301 redirect and this URL rewrite in terms of SEO and link value?

For URLs that require login, should our redirect be 301 or 302?
We have a login required section of our website that is being crawled and reporting as potential issues in Webmaster Tools. I'm not sure what the best solution to this is - is it to make URLs requiring a login noindex/nocrawl? Right now, we have them 302 redirecting to the login page, since it's a temporary redirect, it seems like it isn't the right solution. Is a 301 better?

How to 301 redirect old wordpress category?
Hi All, In order to avoid duplication errors we've decided to redirect old categories (merge some categories).
Intermediate & Advanced SEO | | BeytzNet
In the past we have been very generous with the number of categories we assigned each post. One category needs to be redirected back to blog home (removed completely) while a couple others should be merged. Afterwords we will re-categorize some of the old posts. What is the proper way to do so?
We are not technical, Is there a plugin that can assist? Thanks0 -
301 Redirects After Company Acquisition
We recently acquired a company, and now we are going to redirect all of the pages on their site to their respective pages on our site. Do we need to keep the original pages on their site active? For how long? Ideally, we would like to redirect everything and remove the old site entirely so we don't have to pay to keep hosting it. Is this possible? Thanks!

How long is it safe to use a 302 redirect?
Hi All, Lets assume there is site A and site B, both sites are live on the internet today as standalone businesses, but they sell very similar products. Site B has built up some link equity and will eventually become the domain for site A due to an organisational re-brand. For the time being however site A will remain, but site B needs to disappear temporarily, but not lose the link equity which has been built up against it. My current thinking is to 302 redirect site B to site A such that users and search bots accessing site B will be redirected to site A whilst leaving the link equity that exists against site B fully intact and allowing us to continue to grow it should we wish to. The question is, does anybody have a view on how long it is safe to use a 302 temporary redirect for? i.e., is 8-10 months to long. Thanks, Ben
