        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."

              Found a cache of old domain names, should I link or 301 redirect

              We have found a cache of about 10 URLs, some are ranking above our main URL in Google SERPS. What is the best course of action here? a. Redirect all to the homepage?
              b. Link all domains to the homepage?
              c. Link all domains to select pages on on main site, being careful not to anchor text spam
              d. 301 redirect all to the main site. Is there any disadvantage to your recommendation? Is there likely to be a penalty incurred? I feel like we'll get the strongest increase in rankings by following option c but it feels like option d may be safer. Thanks in advance for your help!

              Hundreds of 301 Redirects. Remove Pages or Not?

              Hi Mozers, I have a website that has literally got hundreds of 301 redirects. I had a close look at these URLs and only some of them have backlinks to it and remaining all of them are not indexing in Google and has got not backlinks at all. Based on what I have noticed experts mentioning, loads of 301 redirects can potentially slow down the site speed. In a case like the website I have, should I completely take off the pages from website to reduce the number of 301 redirects or should I leave 301 redirects? There is no traffic or backlinks coming from these URLs. Malika

              Penalty after 301 redirect?

              We run a training center. We had 1 main website and 2 dedicated websites to certain themes. The 2 dedicated websites are older and the main website is about 6 months old. The 2 dedicated websites had a top 5 ranking for their most important keywords. 2 weeks ago we imported all the content from the dedicated websites into the main website. Then immediately after we did a perfect 301 redirect of these websites to the main website. 2 SEO companies checked it for us and so I'm very sure this is done right. Google immediately caught this up and gave the main website a boost. We where in the top 10 for many important keywords for 1 week. The next week all our rankings dropped. We only have a top 50 ranking for 10 keywords. Before it was 75 keywords in the top 20. Do you know what could have caused this? Any suggestion, thought, ... is welcome!

              Blog tags are creating excessive duplicate content...should we use rel canonicals or 301 redirects?

              We are having an issue with our cilent's blog creating excessive duplicate content via blog tags.  The duplicate webpages from tags offer absolutely no value  (we can't even see the tag).   Should we just 301 redirect the tagged page or use a rel canonical?

              Redirect non www. domain to WWW. domain for established website?

              Hey guys, The website in question has been online for more than 5 years but there are still 2 versions of the website. Both versions are indexed by Google and of course, this will result in duplicate content. Is it necessary to redirect the non-www domain to the www. domain. What are the cons and advantages? Will a lot of organic traffic be lost at first (if non-www are getting a good amount of traffic)? Thanks.

              How many pages to 301 Redirect

              Hi Mozzers, My site has 11,200 pages indexed in Google and I'm looking to remove some of the lesser content which should probably have been picked up by Panda. However these pages work out to about 1,100 in total and I'm not sure whether to remove these bit by bit or just do it in one fell swoop? Does Google not like a site's indexed pages fluctuating too quickly? Are there any other considerations I should be aware of? 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
