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."

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.

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.

301 Redirect of subdomain?
Fellow Mozzers, I'm having a hard time wrapping my brain around a redirect issue and thought it was worth posing the question to the Moz community. I did a search first but couldn't find the exact answer I was looking for. How does a 301 redirect work when you redirect a sub domain example.homepage.com to www.homepage.com but you keep the sub directories of example.homepage.com/page-1 active and are trying to rank them? I'm dealing with a current project where this is happening and this doesn't make sense to me, to redirect the subdomain if you're also trying to rank/create search traffic for pages, sub directories on example.homepage.com. This also get's into the debate of if a sub domain site is viewed as it's own website and therefore has to rank itself. If this is true, it seems like we're kind of killing the authority of the site by redirecting it. Additionally, www.homepage.com has a much stronger link profile than example.homepage.com I hope this makes sense. Any thoughts are appreciated. Thanks for your time.

Do I need to use canonicals if I will be using 301's?
I just took a job about three months and one of the first things I wanted to do was restructure the site. The current structure is solution based but I am moving it toward a product focus. The problem I'm having is the CMS I'm using isn't the greatest (and yes I've brought this up to my CMS provider). It creates multiple URL's for the same page. For example, these two urls are the same page: (note: these aren't the actual urls, I just made them up for demonstration purposes) http://www.website.com/home/meet-us/team-leaders/boss-man/
Intermediate & Advanced SEO | | Omnipress
http://www.website.com/home/meet-us/team-leaders/boss-man/bossman.cmsx (I know this is terrible, and once our contract is up we'll be looking at a different provider) So clearly I need to set up canonical tags for the last two pages that look like this: http://www.omnipress.com/boss-man" /> With the new site restructure, do I need to put a canonical tag on the second page to tell the search engine that it's the same as the first, since I'll be changing the category it's in? For Example: http://www.website.com/home/meet-us/team-leaders/boss-man/ will become http://www.website.com/home/MEET-OUR-TEAM/team-leaders/boss-man My overall question is, do I need to spend the time to run through our entire site and do canonical tags AND 301 redirects to the new page, or can I just simply redirect both of them to the new page? I hope this makes sense. Your help is greatly appreciated!!0 -
How to stop Google crawling after 301 redirect?
I have removed all pages from my old website and set 301 redirect to new website. But, I have verified old website with Google webmaster tools' HTML verification file which enable me to track all data and existence of pages in Google search for my old website. I was assumed that, Google will stop crawling and DE-indexed all pages after 301 redirect. Because, I have set 301 redirect before 3 months. Now, I'm able to see Google bot activity on my website with help of Google webmaster tools. You can find out attachment to know more about it. How can it possible & How Google can crawl removed pages? You can see following image to know more about it. First & Second

Can penalties be passed via 301 redirect?
I have a well established domain that's been hit with some penalties. It hasn't been nuked off the map, just downgraded, especially on short-tail, one word type queries. I'm planning on redirecting this domain to another well established domain. The domains already have a history of lots of interlinking and are very similar from a subject matter standpoint. I feel that the penalized domain has been hit with an "over-optimization" of link anchor text penalty (I'm hoping it's algorithmic, but it could be manual). My question is if anyone has ever heard of a penalty like this being transferred to another domain through a 301 redirect. My hope is that the penalty just puts a cap on how much juice the redirect can pass, rather than transferring the penalty to the other domain itself. Any thoughts on this?

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
