301 or 302 Redirects to Mobile Site
-
When it's detected that a mobile device is accessing the site it has the ability to redirect from www.example.com to m.example.com. Does it make more sense to employ a 301 or 302 redirect here?
Google says a 301 but does not explain why (although usually I stick to "when in doubt, 301") . It seems like a 302 would prevent passing link juice to the mobile site and having mobile-optimized results also showing up in Google's index. What is the preference here?

Thanks for sharing that link. That's interesting that Google is telling you to create a 301 for desktop to mobile redirects. I've always used this script and it's worked great never negatively impacted my Mobile or Desktop SERPS:

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)

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.

Multilingual Site and 301 redirection
Hey there awesome people of Moz I have this site that has many languages in it. The main language is English and my developer did the following www.example.com ( is the main site ) which redirects with a 301 to www.example.com/en if your geo location is supported by our languages then you will automatically be redirected to whatever language you have in your country but does the first language with is english have to 301 redirect to www.example.com/en ? I thought that the right way is to just leave /en at the root file. Thanks in advance

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?

302 redirects in the sitemap?
My website uses a prefix at the end to instruct the back-end about visitor details. The setup is similar to this site - http://sanfrancisco.giants.mlb.com/index.jsp?c_id=sf with a 302 redirect from the normal link to the one with additional info and a canonical tag on the actual URL without the extra info ((the normal one here being http://sanfrancisco.giants.mlb.com,) However, when I used www.xml-sitemaps.com to create a sitemap they did so using the URLs with the extra info on the links... what should I do to create a sitemap using the normal URLs (which are the ones I want to be promoting)

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?

Are there any negative effects to using a 301 redirect from a page to another internal page?
For example, from http://www.dog.com/toys to http://www.dog.com/chew-toys. In my situation, the main purpose of the 301 redirect is to replace the page with a new internal page that has a better optimized URL. This will be executed across multiple pages (about 20). None of these pages hold any search rankings but do carry a decent amount of page authority.

How To 301 Redirect .html pages
I need to redirect a page/URL that is purely .html to a new location. I don't know how to do this. All the redirects I can find are for server side code pages .php/.aspx etc. From my understanding I can't put a server side redirect in a .html file. I am hosting on a microsoft server, however the new page I am redirecting to is .php. I am running some WordPress (.php) files on the server. I need to make it redirect before the old page loads so visitors don't start reading something that is about to get redirected Can someone please help me?
