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."

Can some sort of wildcard redirect be used on a single folder path?
We have a directory with thousands of pages and we are migrating the entire site to another root URL. These folder paths will not change on the new site, but we don't want to use a wildcard to redirect EVERYTHING to the same folder path on the new site. Setting up manual 301 redirects on this particular directory would be crazy. Is there a way to isolate something like a wildcard redirect to apply only to a specific folder? Thanks!

Is there any benefit to changing 303 redirects to 301?
A year ago I moved my marketplace website from http to https. I implemented some design changes at the same time, and saw a huge drop in traffic that we have not recovered from. I've been searching for reasons for the organic traffic decline and have noticed that the redirects from http to https URLs are 303 redirects. There's little information available about 303 redirects but most articles say they don't pass link juice. Is it worth changing them to 301 redirects now? Are there risks in making such a change a year later, and is it likely to have any benefits for rankings?

Switching from HTTP to HTTPS: 301 redirect or keep both & rel canonical?
Hey Mozzers, I'll be moving several sites from HTTP to HTTPS in the coming weeks (same brand, multiple ccTLDs). We'll start on a low traffic site and test it for 2-4 weeks to see the impact before rolling out across all 8 sites. Ideally, I'd like to simply 301 redirect the HTTP version page to the HTTPS version of the page (to get that potential SEO rankings boost). However, I'm concerned about the potential drop in rankings, links and traffic. I'm thinking of alternative ways and so instead of the 301 redirect approach, I would keep both sites live and accessible, and then add rel canonical on the HTTPS pages to point towards HTTP so that Google keeps the current pages/ links/ indexed as they are today (in this case, HTTPS is more UX than for SEO). Has anyone tried the rel canonical approach, and if so, what were the results? Do you recommend it? Also, for those who have implemented HTTPS, how long did it take for Google to index those pages over the older HTTP pages?

Can I dissavow links on a 301'd website?
So we are performing link removal for a client on his old website (A), which is being 301 redirected to his new website (B). We have identified toxic links on site A and are removing, once complete we will undo the current 301, confirm a new GWT account for website A, and then submit the disavow report. We would then like to reapply the 301 redirect to site B while we are waiting for Google to process the disavow report, the logic being we can retain some current rankings on site B while waiting for the disavow to process on site A. Has anyone had experience with this method? I foresee some potential issues here but am interested to here from others on this. 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 | | 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.

Language Detection redirect: 301 or 302?
We have a site offering a voip app in 4 languages. Users are currently 302 redirected from the root page to /language subpages, depending on their browser language. Discussions about the sense of this aside: Is it correct to use a 302 redirect here or should users be 301 redirected to their respective languages? I don't find any guideline on this whatsoever...

Splitting one Website into 2 Different New Websites with 301 redirects, help?
Here's the deal. My website stbands.com does fairly well. The only issue it is facing a long term branding crisis. It sells custom products and sporting goods. We decided that we want to make a sporting goods website for the retail stuff and then a custom site only focusing on the custom stuff. One website transformed and broken into 2 new ones, with two new brand names. The way we are thinking about doing this is doing a lot of 301 redirects, but what do we do with the homepage (stbands.com) and what is the best practice to make sure we don't lose traffic to the categories, etc.? Which new website do we 301 the homepage to? It's rough because for some keywords we rank 3 or 4 times on the first page. Scary times, but something must be done for the long term. Any advise is greatly appreciated. Thank you in advance. We are set for a busy next few months 🙂
