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."

301 Redirects for Multiple Language Sites in htaccess File
Hi everyone, I have a site on a subdomain that has multiple languages set up at the domain level: https://mysite.site.com, https://mysite.site.fr , https://mysite.site.es , https://mysite.site.de , etc. We are migrating to a new subdomain and I am trying to create 301 redirects within the htaccess file, but I am a bit lost on how to do this as it seems you have to go from a relative url to an absolute - which would be fine if I was only doing this for the english site, but I'm not. It doesn't seem like I can go from absolute url to an absolute url - but I could be wrong. I am new to editing the htaccess file - so I could definitely use some advice here. Thanks.

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?

Remove URLs that 301 Redirect from Google's Index
I'm working with a client who has 301 redirected thousands of URLs from their primary subdomain to a new subdomain (these are unimportant pages with regards to link equity). These URLs are still appearing in Google's results under the primary domain, rather than the new subdomain. This is problematic because it's creating an artificial index bloat issue. These URLs make up over 90% of the URLs indexed. My experience has been that URLs that have been 301 redirected are removed from the index over time and replaced by the new destination URL. But it has been several months, close to a year even, and they're still in the index. Any recommendations on how to speed up the process of removing the 301 redirected URLs from Google's index? Will Google, or any search engine for that matter, process a noindex meta tag if the URL's been redirected?

DNS or 301 Website Redirect
We are running a marketplace site, so we have thousands of vendors selling their products on our site. Each vendor has a Profile page and we are soon to launch a premium store-front that is white label. Many of these vendors will want to point a custom url to their premium store-front (which is a sub domain of the marketplace) and we are trying to get an understanding of how we should instruct them to point their url in a way that will give the main marketplace site the seo juice. We also want to understand what will show up in the address bar. Will it be their url or our sub domain? Will any of the marketplace seo juice boost their url local listing status?
