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."

Phasing in new website on www2 domain - 301 plan
Hi, I work for a large company and we're planning to phase in a new website. The idea is to develop key journeys on the new site and serve them on a www2 domain, removing them from the old website which is served on the www domain. The reason for this is because the old website is over 2,000 pages, and the management want to see new, improved journeys sooner rather than later. So, rather than launching all new pages and journeys at the same time, which will take a long time to design and develop, key journeys will move across to the new site / design sooner and made available to visitors. Whilst the overall journey might be a bit disjointed in parts (i.e. sending people from old to new site, and vice versa) I can't see a better way of doing it... Once all new content is complete, 301s will be implemented from old content on www. to new content www2. Once the phasing is complete, and all new content is in place on www2, 301s will be implemented to point everything back to www. Does anybody see any problems with this approach? Or any ideas on how to better handle this situation? Thanks Mozzers!

301 Redirect in breadcrumb. How bad is it?
Hi all, How bad is it to have a link in the breadcrumb that 301 redirects? We had to create some hidden category pages in our ecommerce platform bigcommerce to create a display on our category pages in a certain format. Though whilst the category page was set to not visable in bigcommerce admin the URL still showed in the live site bread crumb. SO, we set a 301 redirect on it so it didnt produce a 404. However we have lost a lot of SEO ground the past few months. could this be why? is it bad to have a 301 redirect in the breadrcrumb.

Website Redesign, 301 Redirects, and Link Juice
I want to change my client’s ecommerce site to Shopify. The only problem is that Shopify doesn’t let you customize domains. I plan to: keep each page’s content exactly the same keep the same domain name 301 redirect all of the pages to their new url The ONLY thing that will change is each page’s url. Again, each page will have the exact same content. The only source of traffic to this site is via Google organic search and sales depend on the traffic. There are about 10 pages that have excellent link juice, 20 pages that have medium link juice, and the rest is small link juice. Many of our links that have significant link juice are on message boards written by people that like our product. I plan to change these urls and 301 redirect them to their new urls. I’ve read tons of pages online about this topic. Some people that say it won’t effect link juice at all, some say it will might effect link juice temporarily, and others are uncertain. Most answers tend to be “You should be good. You might lose some traffic temporarily. You might want to switch some of your urls to the new structure to see how it affects it first.” Here’s my question: 1) Has anyone ever done changed a url structure for an existing website with link juice? What were your results and do you have a definitive answer on the topic? 2) How much link juice (if any) will be lost if I keep all of the exact content the same but only change each page’s url? 3) If link juice is temporarily lost and then regained, how long will it be temporarily lost? 1 week? 1 month? 6 months? Thanks.

Flip-Flopping domains - 301 redirect question
We have a client who has had the following domain setup for some time: longdomain.com 301 -> shortdomain.com Now, they would like to go back to the original longdomain.com, and will have the following setup: shortdomain.com 301 -> longdomain.com Obviously, I'm concerned about redirect loops cached in the browser. I plan to have the 301's from longdomain.com changed over to 302's for two weeks ahead of the change, so that hopefully when the change happens, browsers and search engines are more ready to respond. I also plan to establish rel=canonical on the longdomain.com pages after the switch. Is there anything else you'd recommend to help with the changeover? Should we plan for an intermediary period were both domains are serving the content, so that the redirects can be purged, before being re-established the other direction? Thanks in advance.

Client rebranded with a new website but can't migrate now defunct franchise website to new website.
Hi everyone, My client is a chain of franchised restaurants with a local domain website named after the franchise. The franchise exited the market while the client stayed and built its own brand with a separate website. The franchise website (which is extremely popular) will be shut down soon but the client will not be able to redirect the franchise website to the new website for legal reasons. What can I do to ensure that we start ranking immediately for the franchise keyphrase as soon as the franchise website is shutdown. We currently have the new website and access to the old website (which we can't redirect) Thanks, T

Can I use the same set of social media accounts on two sites?
I have a client who's company name / main site name is not his name. All his social accounts connected to his site are in his name. The site is verified with Google Places, etc. Now he asked for me to create a site for him in his own name with some similar info and a lot of new info. The million dollar question is do I use the same social media accounts on the new site? Facebook, twitter, youtube, etc? Will that hurt the organic rankings of the main site? I've seen this similar situation before. You may have someone who works at a large corporation who is mentioned on the main site has their own personal profile site just about them. Where they can go more in depth about things they are doing. If the other set of social account where in the company name it would be a no brainer to create new social accounts in his name. The issue is the main companies social accounts are already in his name.
