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 and impact on page authority
I need to restructure a section of my website, changing some page titles and moving some pages to other sections. This will then change the URLs but the CMS I use will automatically create 301 redirects so the old URLs still work. The question is, will this have any negative impacts on page authority/page rank? From what I've read, it seems having 301's used to have a negative impact but doesn't anymore?

Will this 301 redirects help me?
Hello, recently, I found out about all the SEO advantages from 301 redirects. I had 3 websites that are now expired, their topic was Counter Strike 1.6 servers. All of these websites were registered 9 years ago and have few good backlinks (from website with 1%-3% spam score and DA 30+). Now I have one website that is not only about Counter Strike 1.6 but also many other Steam shooter games. If I revive these 3 old domains and 301 redirect them to my new one, will it help me with SEO and increase my ranking on Google?

Mass 301 redirect in htaccess
I use ScreamingFrog to generate sitemaps for my Magento 2 multistore, but I recently noticed two issues. Each category/page has two URLs. One with / and the end and one without. Every product has two URLs. One with /product-name and the other /shop/product-name. The URLs are canonicalised, but this is still a problem and I'm not sure exactly how to execute this in the htaccess file. So I need to: Remove all URLs without the / at the end and redirect them all to the URL with / at the end. Or vice versa. 301 redirect every single product (there are over 400) from shop/product-name to /product-name. How do I do this en mass in the htaccess file?

301 Redirect and Loss of PA and DA
Mozzers, http:itsgr82bme.com Old domain homepage had a DA of 24 and a PA of 36 Currently redirected to http://thekidstime.com Homepage shows a DA of 6 and a PA of 1. That is a significant loss of authority. I thought a 301 is supposed to be better than that. What gives? What are the next steps, asking the old backlinks to update their links? Thanks for your help, Matt

Localized Domain Issue - Can I use Search Console to solve this?
Struggling through trying to resolve a complicated search issue - would appreciate any community input or suggestions. The Background Info We have several brand sites and each one has both a .ca and .com domain. For some reason, our website platform was created in a way that hundreds of pages on the .com domain have an equivalent page on the .ca domain, which are all 301'ed to the appropriate .com pages. Example below for clarity: www.domain.ca/gadget/brand - 301 Redirected to: www.domain.com/gadget/brand www.domain.ca/gadget/en/brandcanada = Proper .ca Canadian URL (where en is the language - fr exists as well) The Problem Because these .com pages exist under the .ca domain as well, they have started to outrank the correct .ca pages on Google. This has led to Canadian customers finding incorrect information, pricing, and reviews for these products - causing all sorts of customer service issues and therefore affecting our sales. I am being told that to properly fix the issue, and remove the incorrect URLs under the .ca domain would be prohibitively expensive in terms of resources, so I'm left trying to fix this via means available to me (i.e. anything but a change to how the platform is currently setup). The Attempted Fix I've submitted proper sitemaps for the .ca brand sites, and we have also created a robots.txt file to be accessed only when the site is crawled through the .ca domain. In that robots.txt, we have Disallowed crawling of any /gadget/brand/ URLs for the .ca domain. This was done a week ago and I am still seeing the .com URL show up in search results. The Question Should I be submitting any www.brand.ca/gadget/brand/ URLs to be temporarily removed from Google? Because of the 301 redirect in place from www.brand.ca/gadget/brand to www.brand.com/gadget/brand, I am hesitant to do so, as I do not want the .com URL removed. Will Google simply remove the .ca URL and not follow the 301 redirect to remove that URL as well? Any additional insight or feedback would be awesome as well.

.Com version of my site is ranking better than .co.uk for my UK Website for branded search. 301 redirect mess
Dear Mozzers, I have an issue with my UK Website (short url is - http://goo.gl/dJ7IgD ) whereby when I type my company name in to google.co.uk search the .com version returns in Search as opposed to the .co.uk and from looking at open site explorer the page rank of the .com is higher than the .co.uk ?. Infact I cant even see the .co.uk homepage version but other pages from my site. The .com version is also 301'd to the .co.uk. From looking at Open Site Explorer, I have noticed that we have more links pointing to .com as opposed to .co.uk. Alot of these are from our own separate microsites which we closed down last year and I have noticed the IT company who closed them down for some reason 301'd them to the .com version of our site as opposed to the .co.uk but If I look in http://httpstatus.io/ (http status checker tool) to check one of these mircosites it shows - 301 - 302 - 200 status codes which to me looks wrong ?. I am wondering what it should read ... e.g should it just be a 301 to a 200 status code ?. My Website short url is - http://goo.gl/dJ7IgD and an example of some of 10 microsites we closed down last year which seems to be redirected to .com is http://goo.gl/BkcIjy and http://goo.gl/kogJ02 As these were redirected almost a year ago - it is okay if I now get them redirected to the .co.uk version of my site or what should I do ? They currently redirect to the home page but given that each of the microsites are based on an individual category of my main site , would it be better to 301 them to the relevant category on my site. My only concern is that , may cause to much internal linking and therefore I wont have enough links on my homepage ? How would you suggest I go about building up my .co.uk authority so it ranks betters than the .com- I am guessing this is obviously affecting my rankings and I am losing link juice with all this. Any advice greatly appreciated . thanks Pete

My website has dropped in the rankings drastically. How can I get it back up the SERPs?
I manage a website that I took over 6 months ago - the site was sitting happily on page one of google so I haven't had to do much to keep it there - other than a few onsite improvements. However, last week the site dropped off the SERPs. The site is http://www.pro-techairconditioning.co.uk/content/home.html Could someone please suggest reasons for this and ways to solve the problem? Thanks

When is it time to kill 301 redirects
3 months we updated our site design design and as such lots of page urls changed. At the time we 301 redirected about 100 pages. (All pages are on the same domain - 301 redirects like .com/about-us/company to .com/company) Anyhow my question is should I leave these redirects active indefinitely or kill them assuming value has passed through by now? Your Thoughts are welcomed. Thanks, Glen.
