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.

Htaccess - Redirecting TAG or Category pages
Hello Fellow Moz's, We have an issue redirecting some /TAG and /Category pages to inner pages. As an example we use: RedirectMatch 301 /category/Sample-Category(.*) https://OurDomain.com.au/New-Page//$1 That works well. The issue is we have other categories and tags that are named similar to /Sample-Category As an example, if we try to redirect /Sample-Category-1 to /New-Page-1 - it will not work, and redirects to /New-Page I assume this is because /Sample-Category is already being redirected, so anything after /Sample-Category like -1 or -2 or -3 etc, will not be recognized. Anyone know of a workaround?

Redirected Old Pages Still Indexed
Hello, we migrated a domain onto a new Wordpress site over a year ago. We redirected (with plugin: simple 301 redirects) all the old urls (.asp) to the corresponding new wordpress urls (non-.asp). The old pages are still indexed by Google, even though when you click on them you are redirected to the new page. Can someone tell me reasons they would still be indexed? Do you think it is hurting my rankings?

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

Should I redirect images when I migrate my site
We are about to migrate a large website with a fair few images (20,000). At the moment we include images in the sitemap.xml so they are indexed by Google and drive traffic (not sure how I can find out how much though). Current image slugs are like:

http://website.com/assets/images/a2/65680/thumbnails/638x425-crop.jpg?1402460458 Like on the old site, images on the new website will also have unreadable cache slugs, like:
http://website.com/site_media/media/cache/ce/7a/ce7aeffb1e5bdfc8d4288885c52de8e3.jpg All content pages on the new site will have the same slugs as on the old site. Should I go through the trouble of redirecting all these images?0 -
Redirect at Registrar or Server
Hi folks, I have run into a situation were a new client has 3 TLDs (e.g. mycompany.com, mycompany.org and mycompany.biz), all with the same content. They are on a Windows IIS environment, which I am not familiar with. Until now, all of my clients have been Linux/Apache environment, so I always dealt with these issues utilizing htaccess. Currently all resolve to the same IP, but the URL remains the same in the browser address field (e.g. if you type-in mycompany.org - it remains as such). We want the .org and .biz version to 301 Redirect to the .com TLD. I am wondering what the best practice might be in this situation? Could we simply redirect at the registrar level or would implementation at the server level be best? If so, I would really appreciate an example from someone with experience implementing redirects on IIS. Thank you!

CPanel Redirect not allowing login access.
Using the redirect function in cPanel I am able to create the 301 redirect that I need to not have duplicate content issues in Moz. However, the issue now is that when I try to login to domain.com/login it redirects to domain.com/index.php?q=admin, which is not a page on the site and I can no longer login. I have checked the htaccess file and it appears that the entry is correct ( I originally thought that the cPanel redirect was not writing access correctly ). I am not sure if there is a small detail that I am missing with this or not. So my main question is how do I redirect my site to remove dup content errors while retaining the login at domain.com/admin and not be redirected to domain.com/index.php?q=admin? Thank you ahead of time for your assistance.

Redirecting Canonical 301s and Magento Website
I have an issue with a client's website where it has 3700+ pages, but roughly half of them are duplicates. Thankfully, the only difference between the original and the duplictes is the "?print" at the end of each URL (I suppose this is Magento's way of making a printable page version of the same page. I don't know, I didn't build it.) My questions is, how can I get all the pages like this http://www.mycompany.com/blah.html?print to redirect to pages like this... http://www.mycompany.com/blah.html Also, do they NEED to be Canonical, or will a 301 redirect be sufficient. Also, after having done this, if anybody knows, is there a way I can turn that feature off in Magento, because we're expanding our product line, and I don't want to have to keep chasing after these "?print" pages after the fact.
