How does a Responsive Site poentially kill SEO?
I've seen a few feeds on twitter how a website took a rankings dive after implementing a Responsive theme; yet, it's not clear to me what is actually going on within a Responsive site that would cause the SEO rank to tank? I can only speculate that it introduces a bunch of 404 errors, or that it changes all of the URLs into gibberish, so you loose all of the links coming into your website if not 301'ed?
Can someone clarify, what are the actual mechanical issues on a Responsive website that becomes a concern to SEO? Thanks.

Hello Jason,
This is one of the best (ok, IMO the best explanation of responsive design I have seen to date) especially laying out the difference between server side - dynamic design - and responsive. The thought you placed into this whole answer to provide one that is concise and cogent is excellent.
I like the point up about the lazy designer and page speed as something to be aware of.
Typically, as an agency, we are not often dealing with a client bringing mobile and desktop forward. It is more likely we will be dealing with someone whose site has lost appeal, power, relevance, etc. and we typically build responsive for all. So the thoughts around url changes are helpful as well.Thank You,
Robert

Hi Steve,
At this point I wouldn't say responsive design is fundamentally better or worse than other options from an SEO perspective. But there are a number of SEO pitfalls you'd want to avoid when moving from some other structure, to a responsive design.
First a Quick Set of Definitions:
"Responsive Design" means different things to different people. If you ask 5 people to define it, you'll get 8 different definitions.
Most people (including Google and the W3C) would say that "responsive design" is primarily using media queries and proportional layouts to adapt a webpage to different viewport widths on the client.
Detecting UserAgents is actually a server side technique that would commonly be used for an alternative approach to responsive design, that google calls "Dynamic Design".
Many people mistakenly call both Serve Side Adaption and Client Side Adaption "Responsive Design" when in fact there are important distinctions for SEO.
Changes in URLS can hurt SEO
In either case, if you're moving from having separate URL's for your desktop (www.mysite.com) and mobile (m.mysite.com) to a new design based on responsive or dynamic design, then you are going to be changing some URL's in the process. Any time you change your URL's you run the risk of hurting your SEO. The best practice is to 301 redirect all the m.mysite.com pages to their new www.mysite.com responsive design equivalents If you happen to be changing the main desktop URL's at the same time, it's even more important that you use 301's to preserve the equity in your old URLs.
Responsive vs. Dynamic
Google loves client side responsive design (it's the easiest/cheapest for Google to crawl), so it's actually their first choice, and you don't have to do anything special for responsive design SEO.
If however, you are doing "Dynamic Design" such as detecting user agents on the server to adapt pages for different devices, then you need to tell Google that the page will look different for different user agents. This is done using the Vary HTTP header.
Content Differences
Responsive Design means that you basically have the same content on your desktop and mobile version of your site. That can mean that you don't have keywords which are popular on mobile devices, such as "download mobile app" which can obviously hurt SEO for those keywords. Having a dynamic site (with different content for mobile and desktop) or even having separate URL's for mobile and desktop can sometimes give you a better chance to optimize your keywords for mobile searches.
Speed
Most Responsive Designs are slower than Dynamic designs or separate URLs. It doesn't have to be that way, as their are work-arounds for Responsive Design speed challenges. But fundamentally, responsive design means downloading more variations and code to the client, than a well behaved dynamic site, which means it's usually slower. Too often, lazy designers use the same images for all devices on a responsive design page, and then it's quite a bit slower.
Pagespeed is an SEO ranking factor so, it can hurt your SEO. If you choose Responsive Design, make sure you are only downloading properly optimized images for each device, and that you have highly optimized the pageload of your responsive design. Your users and your search engines will thank you for having fast pages.
Conclusion
Responsive Design doesn't have to be bad for SEO, and in many cases it is better for SEO than other options. The search engines have given us good options to have optimal SEO with any of the three major techniques for addressing device diversity, so I would't let SEO drive my architecture decision.
I'd choose separate URLs, Dynamic Server Adaption, Responsive Design Client Adaption, or mixes of the last two (Responsive Design with Server Side Components or RESS) based on my user base, the tasks my users are going to want to complete on each device, and my development resources, rather than any concerns over SEO.
All the best.

First, I stumbled onto this discussion and my mouth fell open as I gurgled out ... What the....
So, I then read the good answers from Thomas and Daniel and felt a twinge of relief. Here is what I suggest when you hear something like that: First ask the question It was your site that fell in rankings or someone elses? If they say someone elses, ask if they personally saw the rankings drop post implementation of the new design. If theirs, ask the same pointed questions if you were trying to help someone determine what the problem is.
Now, once you ascertain (and I am willing to bet over 90% fall into this group) that they never personally saw the data, you have answer one: Somebody said that somebody said. OK, not great SEO work. But, if they say it is theirs or they got to dig through, ask this How did it affect the rankings and how did you determine that was the cause? Now you are getting into some serious SEO detective mojo! That's where we find the real answers.Great question Steve!!
Good job Thomas and Daniel, Thanks for keeping the world clean!
Robert
PS - we build a lot of sites and 80% plus are responsive. We have see NO drop in rankings that could be attributable to a responsive design. BTW our site and several of our large firm owned sites are fully responsive and rocking cool. They are fine.

Hi Steve,
I think you should rephrase the question...
How can a responsive design harm SEO?
Typically a responsive design is driven by either USER AGENT or screen size... Both of these, if implemented correctly will not affect the way the Google Bot crawls the site. I would doubt there will be issues with 404's as the URL will be the same regardless of the device.
I would suggest it is poor implementation of the design.
Hope this helps!

The re-ordering of content on a page could give the page different emphasis. You would have to take a look at the page as a Google bot, to determine if the responsive theme displays the content differently. This could even go as far as throwing up links that should be navigational as content. What does or doesn't fall between a
and
makes a difference.
For the most part, I wouldn't expect a properly designed responsive site to change your SEO.

How much is the site architecture impacting my site?
Hi there, I'm interested to learn how much the site archecture of griffith.ie (higher education) maybe impacting our rankings. In recent months there was some changes to the the faculty landing pages but not to the site archecture. The rankings in the last 6 months have dipped a little. There are two main path ways to get to the course. 1. Course finder - https://www.griffith.ie**/find-a-course** => 2. Faculties - https://www.griffith.ie**/faculties** Most of the SEO authority is coming through the Faculties pages as this is where all the courses are found in term of the url structure. For example; https://www.griffith.ie**/faculties/**business/courses/ba-hons-accounting-finance The UX on the site tells a different story and directs people to the course finder. /find-a-course Ideally, I feel the site would benefit much more if all the traffic was directed through the course finder however this would require (I think) a big redevelopment of the search tool and I feel we are diluting our efforts as when somebody arrives to the site through the homepage they go through the course finder and if they come through specific searches they get taken to the specific course page under the faculty section. the site has has this archecture for the best part of 4 years and I'm considering recommend a change if it would greatly improve SEO and UX. Any feedback on this would be great. Many Thanks Rob

Large Global Site Structure
Hi, I have a question about the advised structure for a website that I'm currently building. It's a large international brand with it's main office in the UK. The main website is the .com but there is a growing international franchisee network. I've built the .com site on Wordpress but I'm not sure if I the best way forward would be to create each international website on a separate hosted site or just include it in the .com Wordpress structure using the The WordPress Multilingual Plugin. So to sum up... should I build the entire global network on one domain and then use WPML plugin or should I build separate websites for each International franchisee? Hope some one can educate me on the best route to take. Thanks Moz Community

Is it Bad to Break Up A Site into Multiple Sites?
I have a big cluttered website with endless pages. It's a non-profit that has content for patients, researchers, therapists, etc.. Would it be a bad idea to turn this cluttered site into 3 or more completely different sites, each focused on their specific demographic? Or should I just figure out how to organize the one site better? Thanks for your help!!!

SEO strategy for UK / US websites
Hi, We currently have a UK-focused site on www.palmatin.com ; We're now targeting the North American market as well, but the contents of the site need to be different from UK. One option was to create another domain for the NA market but I assume it would be easier to rank with palmatin.com though. What would you suggest to do, if a company is targeting two different countries in the same language? thanks, jaan

SEO Consulting for HUGE Website. How Big Is TOO Big Of A Change?
SEO Consulting for a HUGE Website. Their h1 tags have instagram/twitter, h2 have their menu/what's trending and h3 is the article title. Here's what I want to do... MY MAIN QUESTION: This site has tens of thousands of pages, all articles beyond the few dozen category/tag pages they have. If I change the structure to the following, will it be too much of a system shock to Google? Will this actually HURT them? Currently on the site: - h1 tags point to Twitter/Instagram sidebar widgets
Web Design | | BrianGilmore
h2 tags point to the menu/what’s trending section (which is the same on every page)
h3 points to the Title of the Article I want to change it to this: - h1 tags should delineate the article's name. That's all they should really be used for.
h2-4 should be reserved for article subheadings to be used by the editorial staff. EDIT: 30% of their >11 million monthly uniques come from search. I don't want to eff with that, but the way that NONE of their pages have optimized words, they have no sitemap, webmaster tools and are still doing this well makes me think that even putting in minimal changes to tidy things up will help them bring it to 70% organic search.0 -
Are Carousels Bad for SEO?
My real estate web site was migrated form Drupal to Wordpress last July. The ranking have dropped a lot since migration. One of the things we changed is that we have added two carousels to the home page. Most of the text is below the carousels. Is this bad for SEO? Thanks,

Effects of HTML layout on Arabic websites and SEO
Hi all, I was hoping someone may be able to help. We are putting together an Arabic website and due to reading right to left as opposed to left to right, the site HTML layout is mirrored compared to normal with everything flipped over. What we are wondering is, will this effect SEO and what are the SEO implications of this? Do the search engine bots automaticlaly know to read the content etc differently and understand that everything is purposely mirrored / the HTML is in a different location compared to a site in the UK / US etc? Any help on this would be most appreciated. Cheers!
