Mobile and SEO
-
We are in the process of building a responsive version of our site for mobile users (currently about 20% of total traffic).
What are the most important SEO considerations we should be aware of when it comes to this kind of project?
Thanks

Hi Casey,
It sounds like you're using dynamic serving, rather than pure responsive design. The difference is that, while both approaches keep a single URL for mobile and desktop users, a responsive approach also keeps the same HTML and simply uses CSS to rearrange content on the page to fit a smaller screen; dynamic serving allows you to actually serve different HTML based on user agent.
The main thing to do for dynamic serving is to make sure you use a Vary HTTP User Agent header, to indicate to Google that you are not cloaking but rather are serving different content based on user agent to provide a mobile-friendly experience.
You can find more info on this here: https://developers.google.com/webmasters/smartphone-sites/details

Actually it MAY BE RADICALLY different than building a site in "traditional" HTML as far as SEO goes.
If site navigation goes away or is radically reduced for responsive (fluid) design reasons, your code needs to embed URLs in the position where it would traditionally appear in the flowing/scrolling content. This also includes ensuring proper category funnels exist at the code level as well.
Also, site speed is a CRITICAL factor (just as it is with any other technology) except its more challenging to ensure your speed is truly maximized depending on the type of code base or framework you use for the responsive design, as well as the optimization of the CDN code and delivery pipe as well.
User WebPageTest.org to thoroughly test each template type (you can choose desktop or mobile device types), along with URIValet.com (the 1.5MBPS speed best reflects what Google tends to see). The key is this isn't about "time it takes a user to see the content" as much as it is "time to process the code that drives the presentation" - page PROCESSING speed.

Thanks Jesse,
We are building (or I should have said - having built for us by a 3rd party) a mobile version (not an m.) of our existing site. I.e. when a user accesses our site from a mobile device the new version is what will display but is the same URL etc - my understanding of responsive, but am I wrong here?
However, we are not able to carry over all the content, pics, video etc from our desktop site to the mobile. Other than this content issue, we should be able to just work as normal?

No different than building your desktop really, as far as technical on-site SEO tactics are concerned.
You say "responsive" but then imply that you are building a separate mobile site. I always recommend building one responsive site but do understand that there are occasionally instances where it doesn't make sense to do so.
Point being, if you're truly building a responsive site then the on-site SEO considerations will be the same as you are building for all devices.

Does having a Blog link in the top level navigation provide any better SEO value, or would having it in a footer or top navigation work just as good?
Trying to decide on whether placing a link to the blog in our top level navigation would have a better SEO value than just placing it in top or footer navigation. I have an ecommerce site.

Confluence and SEO
I think this is a difficult question so apologies in advance and any help would be appreciated! We currently have a large amount of support center content sitting on our main pages which we don’t think is very effective (mainly basic how to guides). We think it is difficult for visitors to understand and the UI is very poor. In order to solve this we’re currently moving this content onto a subdomain using Confluence, a wiki based team collaboration tool (from a company called Atlassian). What we’re planning on doing is very much like what Atlassian themselves have done on this page: https://confluence.atlassian.com/display/ALLDOC/Atlassian+Documentation What are the SEO issues / dangers that I need to consider before moving this content? I’m assuming that as this content will still be on the same domain then we can minimise link equity / authority loss by setting up re-directs to the new content. Also, has anyone had any experience of using Confluence and whether individual pages can be optimised for SEO? I notice that there are lots of add-ins that can be used, one of which is an SEO add-on which allows you to customise things like meta description tags.

Any advice for best practice for mobile versions of websites?
Hi Mozzers, I am looking to develop a mobile version of one of my sites and was wondering what was considered best practice for the following: Where to host it: m.domain.com or domain.com/mobile ? Is rel='canonical' enough to avoid mobile version being indexed or should I use "noindex" on mobile version? How to handle tablets? Which screen size sees mobile version? Which sees full site version? Thanks in advance Geoff

Mobile Sitemap for Site with Media Queries
I'm doing SEO for a site. It uses Media Queries and the CSS to automatically resize the site for the screen size in use. I.e. the site detects the screen size of say an iPhone and the CSS knows which elements to hide for that screen size and still make it look good. This is great because it will automatically cut down the content to display nicely on small screens - obviating the need for a separate mobile site. What kind of sitemap should be generated since the urls are for desktop and mobile use? Yoast (sweet SEO) said it should have both regular and mobile style sitemap to get both the regular and mobile bots to visit, but didn't elaborate on how that sitemap should look. Do you have a recommendation for how exactly the sitemap should look? Should the sitemap have the urls all twice, i.e. once regular and once with the mobile indicator?

Will A DHTML Overlay Or ThickBox Capturing Email Hurt SEO?
Some of our competitors use an overlay window on all their pages to sign a customer up for an email list (usually offering a coupon). Our questions is related to the impact on SEO the overlay might have. Does anyone have experience doing this and is this a "safe" thing to do related to SEO? Thanks...

Drop Down Menus & SEO?
Do these typically have a negative impact on SEO? I know this is kind of a vague question, does it make it harder to spider? Are there SEO friendly ways of coding these? There are so many sites out there that have these, so I've got to assume it's different on a case by case basis.

Old links in Google, new website affecting SEO?
Hi Guys, I have launched my website in october and it has already been indexed by google. Now I'm going to launch my redesign which comes with a new structure, content, links, etc. So the question is, do I have to resubmit my website to google to get rid of old links? Onsite Explorer shows links to my forum which has been spammed with p* stuff which has been already indexed as well. The forum is off now. I want to use SEOmoz to track my new website but I guess this could be a hard thing as old links etc will be shown as well. Is there any tool to let Google know about my changes? Does it affect my SEO in any way? Thank you for your help. Nick
