      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.

                Would You Redirect a Page if the Parent Page was Redirected?

                Hi everyone! Let's use this as an example URL: https://www.example.com/marvel/avengers/hulk/ We have done a 301 redirect for the "Avengers" page to another page on the site. Sibling pages of the "Hulk" page live off "marvel" now (ex: /marvel/thor/ and /marvel/iron-man/). Is there any benefit in doing a 301 for the "Hulk" page to live at /marvel/hulk/ like it's sibling pages? Is there any harm long-term in leaving the "Hulk" page under a permanently redirected page? Thank you! Matt

                301 Redirect - Rank Recovery Examples?

                Hi All, I recently did a 301 redirect. Page to Page and the notified google via its console. Its been 6 days since. The home page and one other high traffic page swopped out with the new domain on google search index with 3-4 drops in ranking for each. The rest of the sites pages have been indexed but still reflect the old domain when searched. Recently today my home page dropped even further to the second page of google index for the specific keyword. Can you share similar experiences and how long it took you to recover rank fully? and how long for all pages to swop out on google search's index? Regards Mike

                Website Redesign, 301 Redirects, and Link Juice

                I want to change my client’s ecommerce site to Shopify. The only problem is that Shopify doesn’t let you customize domains. I plan to: keep each page’s content exactly the same keep the same domain name 301 redirect all of the pages to their new url The ONLY thing that will change is each page’s url. Again, each page will have the exact same content. The only source of traffic to this site is via Google organic search and sales depend on the traffic. There are about 10 pages that have excellent link juice, 20 pages that have medium link juice, and the rest is small link juice. Many of our links that have significant link juice are on message boards written by people that like our product. I plan to change these urls and 301 redirect them to their new urls. I’ve read tons of pages online about this topic. Some people that say it won’t effect link juice at all, some say it will might effect link juice temporarily, and others are uncertain. Most answers tend to be “You should be good. You might lose some traffic temporarily. You might want to switch some of your urls to the new structure to see how it affects it first.” Here’s my question: 1) Has anyone ever done changed a url structure for an existing website with link juice? What were your results and do you have a definitive answer on the topic? 2) How much link juice (if any) will be lost if I keep all of the exact content the same but only change each page’s url? 3) If link juice is temporarily lost and then regained, how long will it be temporarily lost? 1 week? 1 month? 6 months? Thanks.

                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?

                Wildcard Redirects & Canonical Tags

                I have an interesting situation. Current URLs Example1: www.domain.com/red-widgets-cid-1234.html
                www.domain.com/red-widgets-cid-1234-1.html
                www.domain.com/red-widgets-cid-1234-1-1.html Canonical on All Above URLs:
                www.domain.com/red-widgets-cid-1234.html New URL:
                www.domain.com/red-widgets-cid-4567.html Current URLs Example2: www.domain.com/red-widgets-cid-1234+10.html
                www.domain.com/red-widgets-cid-1234+10-1.html
                www.domain.com/red-widgets-cid-1234+10-1-1.html Canonical on All Above URLs:
                www.domain.com/red-widgets-cid-1234+10.html New URL:
                www.domain.com/red-widgets-cid-6789.html Current URLs Example3: www.domain.com/red-widgets-cid-1234+10+5.html
                www.domain.com/red-widgets-cid-1234+10+5-1.html
                www.domain.com/red-widgets-cid-1234+10+5-1-1.html Canonical on All Above URLs:
                www.domain.com/red-widgets-cid-1234+10+5.html New URL:
                www.domain.com/american-red-widgets-cid-6789+5.html I want to make sure all variations of the above URL redirect to the new URLs.  However, as you see in Example 3, we are dealing with variables that are passed on. (+5 in this case). Question 1: What wildcard 301 redirect / regular expression can I use to tackle these ? Question 2: If we redirect www.domain.com/red-widgets-cid-1234+10+5.html to www.domain.com/red-widgets-cid-6789+5.html and www.domain.com/red-widgets-cid-6789+5.html contains the canonical tag www.domain.com/american-red-widgets-cid-6789+5.html, any concerns or red flags here ?

                DNS or 301 Website Redirect

                We are running a marketplace site, so we have thousands of vendors selling their products on our site. Each vendor has a Profile page and we are soon to launch a premium store-front that is white label. Many of these vendors will want to point a custom url to their premium store-front (which is a sub domain of the marketplace) and we are trying to get an understanding of how we should instruct them to point their url in a way that will give the main marketplace site the seo juice. We also want to understand what will show up in the address bar.  Will it be their url or our sub domain? Will any of the marketplace seo juice boost their url local listing status?

                How to stop Google crawling after 301 redirect?

                I have removed all pages from my old website and set 301 redirect to new website. But, I have verified old website with Google webmaster tools' HTML verification file which enable me to track all data and existence of pages in Google search for my old website. I was assumed that, Google will stop crawling and DE-indexed all pages after 301 redirect. Because, I have set 301 redirect before 3 months. Now, I'm able to see Google bot activity on my website with help of Google webmaster tools. You can find out attachment to know more about it.

                Login redirect 302

                Ok - anyone knows what to do with the temporary redirect to the login page? In our e-commerce system we have a checkout page, which requires user to be logged in - if they are not, we redirect them to the login page using simple php header("Locaiton: url"). This however has been found as a Warning as it's a temporary redirect. I can't really put there permanent redirect for obvious reasons so if someone could give me some clue on this situation that would be much appreciated.
