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 Redirecting from domain to subdomain
We're taking on a redesign of our corporate site on our main domain. We also have a number of well established, product based subdomains. There are a number of content pages that currently live on the corporate site that rank well, and bring in a great deal of traffic, though we are considering placing 301 redirects in place to point that traffic to the appropriate pages on the subdomains. If redirected correctly, can we expect the SEO value of the content pages currently living on the corporate site to transfer to the subdomains, or will we be negatively impacting our SEO by transferring this content from one domain to multiple subdomains?

Why some websites can rank the keywords they don't have in the page?
Hello guys, Yesterday, I used SEMrush to search for the keyword "branding agency" to see the SERP. The Liquidagency ranks 5th on the first page. So I went to their homepage but saw no exact keywords "branding agency", even in the page source. Also, I didn't see "branding agency" as a top anchor text in the external links to the page (from the report of SEMrush). I am an SEO newbie, can someone explain this to me, please? Thank you.

Should we 301 redirect old events pages on a website?
We have a client that has an events category section that is filled to the brim with past events webpages. Another issue is that these old events webpages all contain duplicate meta description tags, so we are concerned that Google might be penalizing our client's website for this issue. Our client does not want to create specialized meta description tags for these old events pages. Would it be a good idea to 301 redirect these old events landing pages to the main events category page to pass off link equity & remove the duplicate meta description tag issue? This seems drastic (we even noticed that searchmarketingexpo.com is keeping their old events pages). However it seems like these old events webpages offer little value to our website visitors. Any feedback would be much appreciated.

Multiple 301 redirects for a HTTPS URL. Good or bad?
I'm working on an ecommerce website that has a few snags and issues with it's coding. They're using https, and when you access the website through domain.com, theres a 301 redirect to http://www.domain.com and then this, in turn, redirected to https://www.domain.com. Would this have a deterimental effect or is that considered the best way to do it. Have the website redirect to http and then all http access is redirected to the https URL? Thanks

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 | Nov 18, 2013, 9:59 PM | 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.

Changing a parent category and 301 redirecting
I have a set of three pages that are subpages of a parent. The structure is as follows: mysite.com/directory/personal-widgets mysite.com/directory/commercial-widgets mysite.com/directory/widgets-services The partent page name "directory" really isn't working for where I want these pages to evolve. So I want to change it to "guides" In a world without worrying about google, I would simply change the parent page to guides, so they look like this, and be done with it: mysite.com/guides/personal-widgets But, the obvious problem is that I have external links to the page now. And the pages have a nice PR. And they also have Facebook page Likes and I don't know if I'll lose those. I know that if I should do this I should redirect the pages to the new pages of course. My question is: Will redirecting the old URL to the new URL with a 301 cause anything negative to happen that I might not be expecting? Does Google dislike Redirects for any reason, or understand they are sometimes necessary?

301 - should I redirect entire domain or page for page?
Hi, We recently enabled a 301 on our domain from our old website to our new website. On the advice of fellow mozzer's we copied the old site exactly to the new domain, then did the 301 so that the sites are identical. Question is, should we be doing the 301 as a whole domain redirect, i.e. www.oldsite.com is now > www.newsite.com, or individually setting each page, i.e. www.oldsite.com/page1 is now www.newsite.com/page1 etc for each page in our site? Remembering that both old and new sites (for now) are identical copies. Also we set the 301 about 5 days ago and have verified its working but haven't seen a single change in rank either from the old site or new - is this because Google hasn't likely re-indexed yet? Thanks, Anthony

301 redirect from .html to non .html?
Previously our site was using this as our URL structure: www.site.com/page.html. A few months ago we updated our URL structure to this: www.site.com/page & we're not using the .html. I've read over this guide & don't see anywhere that discusses this: http://www.seomoz.org/learn-seo/redirection. I've currently got a programmer looking into, but am always a bit weary with their workarounds, as I'd previously had them cause more problems then fix it. Here is the solution he is looking to do: The way that I am doing the redirect is fine. The problem is of where to put the code. The issue is that the files are .html files that need to be redirected to the same url with out a .html on them. I can see if I can add that to the 404 redirect page if there is one inside of there and see if that does the trick. That way if there is no page that exists without the .html then it will still be a 404 page. However if it is there then it will work as normal. I will see what I can find and get back. Any help would be greatly appreciated. Thanks, BJ
