303 redirect
-
Hi,
303 redirect is a good thing or not ?
I have a homepage in 2 languages FR and EN > mywebsite.com/fr/ and mywebsite.com/en/.
A 303 redirect is on mywebsite.com to mywebsite.com/fr/.
Thanks
D.

Very descriptive answer. Love that you describe your entire experiment.
Thank you for this extra bit of information.

affect SERPs the 303 redirect remains fairly unknown because it is rarely used.
I came across a website linking to one of my sites with a 303 but I could not find a definitive answer of whether or not this link passed any PageRank. Information online about this was scarce and the only information I found was from people saying that only 301 redirects pass PageRank.
When I checked the status code for 303 redirect at w3.org it was “See other” . The description reads as follows:
“The new URI is not a substitute reference for the originally requested resource. The 303 response MUST NOT be cached, but the response to the second (redirected) request might be cacheable.”
This sounds very black and white and I my initial guess was that Google does not flow PR for 303 redirects. But I was curious, how was Google treating 303 redirects?
I set up an experiment to check how Google was handling the 303. Results below:
*Note: The translation for this keyword is NSFW

Google will show the search result with the URI that is initially requested. It will then show the Page Title and Meta Description (or other descriptive snippet) for the redirected page but it will show the URI from the redirecting page. It is caching the text from the final page but assigning it to the requested page.
How Google caches 303 redirects
Page A 303 redirects to Page B
Title: Page B
URI: Page A
Meta Description: Page B
Since page B does not rank for this keyword it is confirmed that the 303 redirect does not flow PR.
How did I set this test up?
- I chose a rare keyword that had very few pages ranking for it.
- On www.a.com I created two pages containing the keyword with the same exact content (www.a.com/a.htm .com/b.htm)
- One page (www.a.com/a.htm) was linked to internally multiple times
- One page (www.a.com/b.htm) was linked to externally with 303 redirects only from two domains (including www.marketingchip.com)
- The 303 redirects were created on the external pages (www.marketingchip.com/special-doors.html -> 303 -> www.a.com/b.htm)
After a few days neither www.a.com/a.htm nor www.a.com/b.htm appear in the results. However the number one listing for this keyword was forwww.marketingchip.com/special-doors.html but the meta title and the meta description are taken from www.a.com/b.htm. I acquired the information from this URL and would agree with Wesley definitely 301 redirect the link to not use a 303 and less you are trying to accomplish something similar to what it's shown above or in Wesley's comment. http://www.marketingchip.com/seo-experiments/how-does-a-303-redirect-affect-seo/ Sincerely, Thomas

A 303 won't send 'link juice' that means that all the value you website gets on mywebsite.com won't be send to mywebsite.com/fr/. You should use a 301 instead.

Several 301 Redirects to Same Page
Hi, I have 3 Pages we won't use anymore in our website. Let's call them url A, url B and url C. To keep their SEO strength on our domain, I've though about redirecting all of them to url D. For what I understand, when 301 redirecting, about 85-90% of the link SEO juice is passed. Then, if I redirect 3 URLs to the same page... does url D receive all the link SEO juices for URLs added up? (approximately)

e.g. future url D juice = 100% current url D juice + 85% url A juice + 85% url B juice + 85% url C juice Is this the best practice, or is there a better way? Cheers,0 -
How to handle individual page redirects on Wix?
I switched from one domain to another because I wanted a domain that had our company name so it was more brand-y. However, the old domain had better DA/PA. Originally I set up a global 301 from the old to the new, but now I'm finding that I actually need to set up individual 301's from each URL of the old site, or at least from each page. However, I am using Wix so it looks like I can't always do URL-URL 301's, although I can redirect any URL to a page on the new website. The problem is that, in some cases, the content on the new site is different (or, for example, I can only link a particular blog post on the old site back to the new site's blog's main page). How closely do URLS/pages need to resemble each other for link juice to be transferred? Also, should I try to set up all these redirects manually or bite the bullet and go back to using the old domain? The problem is that I did a lot of beginner SEO junk for the new domain, like submitting to a few higher-quality directories, and getting our website on various industry resource sites, etc. I'd need to re-do this entirely if I go back to the old page. What do you think?

Redirecting to a new domain... a second time
Hi all, I help run a website for a history-themed podcast and we just moved it to its second domain in 7 years. We've had very good SEO up until last week, and I'm wondering if I screwed up the way I redirected the domains. It's like this: Originally the site was hosted at "first.com", and it acquired inbound links. However, we then started to host the site on blogger, so we... Redirected the site to "second.blogspot.com". (Thus, 1 --> 2) It stayed here for about 7 years and got lots of traffic. Two weeks ago we moved it off of blogger and into Wordpress, so we 301 redirected everything to... third.com. (Thus, 1 --> 2 --> 3) The redirects worked, and when we Google individual posts, we are now seeing them in Google's index at the new URL. My question: What about the 1--> 2 redirect? There are still lots of links pointing to "first.com". Last week I went into my GoDaddy settings and changed the first redirect, so that first.com now points to third.com. (Thus 1 --> 3, and 2-->3) I was correct in doing that, right? The drop in Google traffic I've seen this past week makes me think that maybe I screwed something up. Should we have kept 1 --> 2 --> 3? (Again, now we have 1-->3 and 2-->3) Thanks for any insights on this! Tom

Iframe redirect bad for SEO?
Hi, I have a website (http://www.blowingminds.de) wich I put a spreadshirt shop into via iframe. The thing is I am not sure on how the iframe effects my SEO? Can I just optimise the main domain for search? Well I want the spreadshirt shop to be found under the domain name (www.blowingminds.de) but the only real way to do it is by implementing an iframe because each spreadshirt shop has its own subdomain eg.: blowingminds.spreadshirt.de but the only real way to do it is via iframe, as they do not offer a complete domain redirect. (Or have I overseen some other way?) I hope you guys can help me on this one 🙂 Thanks in advance. Malte

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

Redirect a subdomain to a subdirectory for SEO purposes.
Hi, I have a site on wordpress and I want to add eCommerce to it. We want to go with Shopify but Shopify only allows to host their platform on a subdomain. I like to have it on a subdorectory, so my question is: Would it make sense to redirect the whole subdomain to a subdirectory (move everything from shop.domain.com to domain.com/shop) for SEO purposes? Would Google see these pages as if they were part of the main domain? Thanks! Julien

Htaccess Redirect with %C2%A0 in URL
Below is my setup for redirects in .htaccess file in my root word press installation. The www to non-www works well, so no problems there Other page redirects work well, too (example: redirect 301 /some-page/ http://mysite.com/another-page/ (I didn't post those because I have a few too many : ) So here it goes... RewriteEngine On
Intermediate & Advanced SEO | | pepsimoz
RewriteCond %{HTTP_HOST} ^www.mysite.com$ [NC]
RewriteRule ^(.*)$ http://mysite.com/$1 [R=301,L] BEGIN WordPress <ifmodule mod_rewrite.c="">RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]</ifmodule> END WordPress redirect 301 /archives/10-college- majors/ http://mysite.com/archives/10-college-majors/ redirect 301 /archives/10-college-%20majors/ http://mysite.com/archives/10-college-majors/ redirect 301 /archives/10-college-%C2%A0majors/ http://mysite.com/archives/10-college-majors/ I'm having a problem with the last 301 redirect: redirect 301 /archives/10-college-%C2%A0majors/ http://mysite.com/archives/10-college-majors/ not working... As you can see I've tried using other varations of the "space" but no go. I also used a redirect in cPanel's Redirect screen; testing all the possible options + wildcard I've also tried this: http://serverfault.com/questions/201829/using-special-characters-in-apache-mod-rewrite-rule (perhaps unsuccessfully, because it caused a 500 server error and it's a different situation in my case) I also saw something here: http://www.webmasterworld.com/apache/3908682.htm but I don't know if it works and how I would implement that + do so without compromising ALL other redirects. Note: the URL displays with a space in the address bar of all major web browsers: http://mysite.com/10-college- majors/ and goes to a 404 page I have a goregous page / PR6 / high authority site linking to the URL on my site, but they copied the URL with a space somehow. I contacted the person responsible for the website and he claims it works fine (aka he didn't check it). Is there a clean way to redirect ONLY this problematic URL without compromising other redirects, etc? Any ideas would be great. I'll respond with progress. Thanks in advance. UPDATE the redirect works, and it did work. Even so, when looking at source of page linking to mine, the URL looks like this: ``` http://mysite.com/archives/10-college- majors/ Clicking the URL in Source View in FireFox takes me to ``` http://mysite.com/archives/10-college-%C2%A0majors/ none of my 301 redirects should direct there. I don't have any redirect plugins either.0
