      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:

          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.

          Hacked website - Dealing with 301 redirects and a large .htaccess file

          One of my client's websites was recently hacked and I've been dealing with the after effects of it. The website is now clean of malware and I already appealed to Google about the malware issue. The current issue I have is dealing with the 20, 000+ crawl errors which are garbage links that were created from the hacking. How does one go about dealing with all the 301 redirects I need to create for all the 404 crawl errors? I'm already noticing an increased load time on the website due to having a rather large .htaccess file with a couple thousand 301 redirects done already which I fear will result in my client's website performance and SEO performance taking a hit as well.

          Javascript onclick redirects / porn sites...

          We noticed around 7 websites which with domains that were just recently registered (with privacy protection). They are using our website keywords/titles and brand name and the sites are mostly porn / junk sites. They don't link to our website directly but use a javascript onclick redirect which is why we think we aren't seeing them in our backlinks report.  We've been in business for over 12 years and haven't come across sites like this before.  We recently lost our first page rankings for a few of our highest converting key phrases and have been digging in to possible causes. Just wondering if these sites could be impacting our results, and how to figure out if there are more like this? Examples: nesat.net
          flowmeterdirectory.biz
          finnsat.net
          dotsjobs.net

          301 Redirect Showing Up as Thousands Of Backlinks?

          Hi Everyone, I'm currently doing quite a large back link audit on my company's website and there's one thing that's bugging me. Our website used to be split into two domains for separate areas of the business but since we have merged them together into one domain and have 301 redirected the old domain the the main one. But now, both GWT and Majestic are telling me that I've got 12,000 backlinks from that domain?  This domain didn't even have 12,000 pages when it was live and I only did specific 301 redirects (ie. for specific URL's and not an overall domain level 301 redirect) for about 50 of the URL's with all the rest being redirected to the homepage. Therefore I'm quite confused about why its showing up as so many backlinks - Old redirects I've done don't usually show as a backlink at all. UPDATE: I've got some more info on the specific back links. But now my question is - is having this many backlinks/redirects from a single domain going to be viewed negatively in Google's eyes? I'm currently doing a reconsideration request and would look to try and fix this issue if having so many backlinks from a single domain would be against Google's guidelines. Does anybody have any ideas? Probably somthing very obvious. Thanks! Sam

          Is a 301 Redirect and a Canonical Tag on Uppercase to Lowercase Pages Correct?

          We have a medium size site that lost more than 50% of its traffic in July 2013 just before the Panda rollout. After working with a SEO agency, we were advised to clean up various items, one of them being that the 10k+ urls were all mixed case (i.e. www.example.com/Blue-Widget). A 301 redirect was set up thereafter forcing all these urls to go to a lowercase version (i.e. www.example.com/blue-widget). In addition, there was a canonical tag placed on all of these pages in case any parameters or other characters were incorporated into a url. I thought this was a good set up, but when running a SEO audit through a third party tool, it shows me the massive amount of 301 redirects. And, now I wonder if there should only be a canonical without the redirect or if its okay to have tens of thousands 301 redirects on the site. We have not recovered yet from the traffic loss yet and we are wondering if its really more of a technical problem than a Google penalty. Guidance and advise from those experienced in the industry is appreciated.

          Question about moving content from one site to another without a 301

          I could use a second opinion about moving content from some inactive sites to my main site. Once upon a time, we had a handful of geotargeted websites set up targeting various cities that we serve. This was in addition to our main site, which was mostly targeted to our primary office and ranked great for those keywords. Our main site has plenty of authority, has been around for ages, etc. We built out these geo-targeted sites with some good landing pages and kept them active with regularly scheduled blog posts which were unique and either interesting or helpful. Although we had a little success with these, we eventually saw the light and realized that our main site was strong enough to rank for these cities as well, which made life a whole lot easier, not to mention a lot less spammy. We've got some good content on these other sites that I'd like to use on our main site, especially the blog posts. Now that I've got it through my head that there's no such thing as a duplicate content penalty, I understand that I could just start moving this content over so long as I put a 301 redirect in place where the content used to be on these old sites. Which leads me to my question. Our SEO was careful not to have these other websites pointing to our main site to avoid looking like we were trying to do something shady from a link building perspective. His concern is that these redirects would undermine that effort and having a bunch of redirects from a half dozen sites could end up hurting us somehow. Do you think that is the case? What he is suggesting we do is remove all of the content that we'd like to use and use Webmaster Tools to request that this content be removed from the index. Then, after the sites have been recrawled, we'll check for ourselves to confirm they've been removed and proceed with using the content however we'd like. Thoughts?

          301 redirect subdirectory to new domain

          I'm planning on using 301 redirects to spin out a subdirectory of my current website to be its own separate domain. For instance, I currently have a website www.website.com and my writers write tech news at www.website.com/news. Now I want to 301 redirect www.website.com/news to www.technews.com. Will this have any negative impact on SEO? What are some steps that I can take to minimize these impacts?

          Multiple 301 redirects for a HTTPS URL. Good or bad?

          I'm working on an ecommerce website that has a few snags and issues with it's coding. They're using https, and when you access the website through domain.com, theres a 301 redirect to http://www.domain.com and then this, in turn, redirected to https://www.domain.com. Would this have a deterimental effect or is that considered the best way to do it. Have the website redirect to http and then all http access is redirected to the https URL? Thanks
