      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.

            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

            How Google handles 303 redirects

            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?

            1. I chose a rare keyword that had very few pages ranking for it.
            2. On www.a.com I created two pages containing the keyword with the same exact content (www.a.com/a.htm .com/b.htm)
            3. One page (www.a.com/a.htm) was linked to internally multiple times
            4. One page  (www.a.com/b.htm) was linked to externally with 303 redirects only from two domains (including www.marketingchip.com)
            5. 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.

                Redirect Issue - Drop in ranking after CMS change

                Hi Website - https://www.aasprint.com.au/ After we moved the site from wordpress to codeIgniter + angular there has been a huge drop in traffic and ranking. One of the thing we recently realized is the redirection - COULD THAT BE THE ISSUE? On the browser and sitemap the URL doesn't have "/" at the end When checked on redirection tool the URL seems to be redirecting to one with "/" at the end Attached are the screenshots.  Also moz bar shows no redirection. However, the issue seems to be flagged by the site audit tool as 301 redirection. Not sure if it's  the cause for the drop. What action to take? Any advice would be much appreciated. V7CNtqt j3dJ4TW

                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?

                301 Redirects to relative URLs not absolute a problem?

                Hi we recently did a migration and a lot of content changed locations see: https://d.pr/i/RvqI81 Basically, the 301 goes to the correct location but its a relative URL (as you can see from the screenshot) rather than absolute URL. Do you think this is a high priority issue from an SEO standpoint, should we get the developer to change the redirects to absolute? Cheers.

                Googlebot being redirected but not users?

                Hi, We seem to have a slightly odd issue. We noticed that a number of our location category pages were slipping off 1 page, and onto page 2 in our niche. On inspection, we noticed that our Arizona page had started ranking in place of a number of other location pages - Cali, Idaho, NJ etc. Weirdly, the pages they had replaced were no longer indexed, and would remain so, despite being fetched, tweeted etc. One test was to see when the dropped out pages had been last crawled, or at least cached. When conducting the 'cache:domain.com/category/location' on these pages, we were getting 301 redirected to, you guessed it, the Arizona page. Very odd. However, the dropped out pages were serving 200 OK when run through header checker tools, screaming frog etc. On the face of it, it would seem Googlebot is getting redirected when it is hitting a number of our key location pages, but users are not. Has anyone experienced anything like this? The theming of the pages are quite different in terms of content, meta etc. Thanks.

                301 redirection pointing to noindexed pages

                I have rather an unusual situation where a recently launched affiliate site does not have any unique content as its all syndicated content. For that reason we are currently using the noindex,nofollow meta tags to keep the pages out of the search engines index until we create unique content for the pages. The problem is that due to a very tight timeframe with rebranding, we are looking at 301 redirecting (on a page to page basis) another high authority legacy domain to this new site before we have had a chance to add unique content to it and remove the noindex,nofollow tags. I would assume that any link authority normally passed through the 301 would be lost in this scenario but Im uncertain of what the broader impact might be. Has anyone dealt with a similar scenario? I know this scenario is not ideal and I would rather wait until the unique content is up and noindex tags are removed before launching the 301 redirect of the legacy domain but there are a number of competing priorities at play outside of SEO.

                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.

                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

                Is it safe to redirect multiple URLs to a single URL?

                Hi, I have an old Wordress website with about 300-400 original pages of content on it. All relating to my company's industry: travel in Africa. It's a legitimate site with travel stories, photos, advice etc. Nothing spammy about. No adverts on it. No affiliates. The site hasn't been updated for a couple of years and we no longer have a need for it. Many of the stories on it are quite out of date. The site has built up a modest Mozrank value over the last 5 years, and has a few hundreds organically achieved inbound links. Recently I set up a swanky new branded website on ExpressionEngine on a new domain. My intention is to: Shut down the old site Focus all attention on building up content on the new website Ask the people linking to the old site to my new site instead (I wonder how many will actually do so...) Where possible, setup a 301 redirect from pages on the old site to their closest match on the new site Setup a 301 redirect from the old site's home page to new site's homepage Sounds good, right? But there is one issue I need some advice on... The old site has about 100 pages that do not have a good match on the new site. These pages are outdated or inferior quality, so it doesn't really make sense to rewrite them and put them on the new site. I call these my "black sheep pages". So... for these "black sheep pages" should I (A) redirect the urls to the new site's homepage (B) redirect the urls the old site's home page (which in turn, redirects to the new site's homepage, or (C) not redirect the urls, and let them die a lonely 404 death? OPTION A: oldsite.com/page1.php -> newsite.com
                oldsite.com/page2.php -> newsite.com
                oldsite.com/page3.php -> newsite.com
                oldsite.com/page4.php -> newsite.com
                oldsite.com/page5.php -> newsite.com
                oldsite.com -> newsite.com OPTION B: oldsite.com/page1.php -> oldsite.com
                oldsite.com/page2.php -> oldsite.com
                oldsite.com/page3.php -> oldsite.com
                oldsite.com/page4.php -> oldsite.com
                oldsite.com/page5.php -> oldsite.com
                oldsite.com -> newsite.com OPTION 😄 oldsite.com/page1.php : do not redirect, let page 404 and disappear forever
                oldsite.com/page2.php : do not redirect, let page 404 and disappear forever
                oldsite.com/page3.php : do not redirect, let page 404 and disappear forever
                oldsite.com/page4.php : do not redirect, let page 404 and disappear forever
                oldsite.com/page5.php : do not redirect, let page 404 and disappear forever
                oldsite.com -> newsite.com My intuition tells me that Option A would pass the most "link juice" to my new site, but I am concerned that it could also be seen by Google as a spammy redirect technique. What would you do? Help 😐
