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

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.

Redirecting non www site
Hello Ladies and Gentlemen. I 100% agree with the redirecting of the non www domain name. After all we see so many times, especially in MOZ how the two different domains contain different links, different DA and of course different PA. So I have posed the question to our IT company, "How would we go about redirecting our non www domain to the www version?", "Where would we do that?", " we cant do the redirect on our webserver because the website is listed as an IP address, not a domain name, so would we do the redirect somewhere at GoDaddy?" who is currently maintain our DNS record So here is the response from IT: " I would setup a CNAME record in DNS (GoDaddy), such that no matter if you go to the bare domain, or the www, you end up in the same place. As for SEO, having a 301 redirect for your bare domain isn't necessary, because both the bare domain and the www are the same domain. 301 is a redirect for "permanently moved" and is common when you change domain names. Using the bare domain or the www are NOT DIFFERENT DOMAINS, so the 301 would not be accurate, and you'd be telling engines you've moved, when you haven't - which may negatively impact your rank. It sounds to me that IT is NOT recommending the redirect. How can this be? Or are we talking about two different things? Will the redirect cause the melt down as the IT company suggests? Or do they nut understand SEO?

Can you redirect specific sub domain URLs?
ello! We host our PDFs, Images, CSS all in a sub domain. For the question, let's call this sub.cyto.com. I've noticed a particular PDF doing really well, infact it has gathered valuable external links from high authoritative sites. To top it off, it gets good visits. I've been going back and forth with our developers to move this PDF to a subfolder structure.
Intermediate & Advanced SEO | | Bio-RadAbs
For example: www.cyto.com/document/xxxx.pdf In my perspective, if I move this and set up a permanent redirect, then all the external links the PDF gathered, link juice and future visits will be attributed to the main website. Since the PDF is existing in the subdomain, I can't even track direct visits nor get the link juice. It appears in top position of Google as well. My developer says it is better to keep images, pdf, css in the subdomain. I see his point and an idea I have is to: convert the pdf to a webpage. Set up a 301 redirect from the existing subdomain to this webpage Upload the pdf with a new name and link to it from the webpage, so users can download if they choose to. This should give me the existing rank juice. However, my question is whether you can set up a 301 redirect for just a single subdomain URL to a folder structure URL? sub.cyto.com/xxx.pdf to www.cyto.com/document/xxxx.pdf?0 -
Does a 302 redirect pass penalties?
I'm having problems finding a definitive answer to this question, there is a lot of rumour and gossip out there but nothing I can rely on. I'm working with a site that received an unnatural links notice followed by a massive drop in search traffic. Looking at the link profile it's pretty much jacked beyond repair and I have recommended that we move over to a fresh domain. However, it's an established brand with many more sources of traffic than organic search. There's no way we can burn all their repeat visits, loyal customers, brand recognition that they've built up over the years so I want to redirect from the old domain to the new. This is not to try and make any SEO gain from the previous site, frankly we don't give a crap about that. We just want to maintain the brand. A 302 is a temporary redirect, this will be a permanent move BUT a 301 will pass on the penalty. So can we safely use a 302 redirect in this situation or is there a better alternative (meta refresh?) Thanks for your help! MB.

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

Are you familiar with how to do this? Thanks, Tyler

How long is it safe to use a 302 redirect?
Hi All, Lets assume there is site A and site B, both sites are live on the internet today as standalone businesses, but they sell very similar products. Site B has built up some link equity and will eventually become the domain for site A due to an organisational re-brand. For the time being however site A will remain, but site B needs to disappear temporarily, but not lose the link equity which has been built up against it. My current thinking is to 302 redirect site B to site A such that users and search bots accessing site B will be redirected to site A whilst leaving the link equity that exists against site B fully intact and allowing us to continue to grow it should we wish to. The question is, does anybody have a view on how long it is safe to use a 302 temporary redirect for? i.e., is 8-10 months to long. Thanks, Ben
