A few important mobile SEO questions
-
I have a few basic questions about mobile SEO. I'd appreciate if any of you fabulous Mozzers can enlighten me.
Our site has a parallel mobile site with the same urls, using an m. domain for mobile and www. for desktop. On mobile pages, we have a rel="canonical" tag pointing to the matching desktop URL and on desktop pages we have a rel="alternate" tag pointing to the matching mobile URL. When someone visits a www. page using a mobile device, we 301 them to the mobile version.
Questions:
1. Do I want my mobile pages to be indexed by Google? From Tom's (very helpful) answers here, it seems that I only want Google indexing the full site pages and if the mobile pages are indexed it's actually a duplicate content issue. This is really confusing to me since Google knows that it's not duplicate content based on the canonical tag. But - he makes a good point - what is the value of having the mobile page indexed if the same page on desktop is indexed (I know that Google is indexing both because I see them in search results. When I search on mobile Google serves the mobile page and when I search on desktop Google serves me the desktop page.)? Are these pages competing with each other? Currently, we are doing everything we can do ensure that our mobile pages are crawled (deeply) and indexed, but now I'm not sure what the value of this is? Please share your knowledge.
2. Is a mobile page's ranking affected by social shares of the desktop version of the same page? Currently, when someone uses the share buttons on our mobile site, we share the desktop url (www. - not m.). The reason we do this is that we are afraid that if people are sharing our content with 2 different url's (m.mysite.com/some_post and www.mysite.com/some_post) the share count will not be aggregated for both url's. What I'm wondering is: will this have a negative effect on mobile SEO, since it will seem to Google that our mobile pages have no shares, or is this not a problem, since the desktop pages have a rel="alternate" tag pointing to mobile pages, so Google gives the same ranking to the mobile page as the desktop page (which IS being shared)?

Thanks so much!
This is exactly what I wanted to know.

After a pretty long conversation a while ago with Google's John Mueller, we tok the plunge and developed mobile version of our site.
We then went on to discuss how Google ranks mobile. He mentioned that it works like a swap, it will look at the content on your desktop version and determine from that what page to display in Google mobile. So a page could simply have little to no text but rank in mobile for the text that is on teh desktop version. Its al bit of a flaw in some ways.
However a big thing taken into account is if your site is mobile optimized, if Google was unable to index your pages it would not be able to determine if you had optimized for mobile and would decrease you ranking opportunity.
Duplicate content is not an issue, especially if its marked as alternate/canonical
As the alternate works like a swap it the social is also not an issue, in fact you are better in some ways having all social and all link building going to one place.
For example my co.uk has no links social shares etc.. its all on my .com, when a user searches for my site in google.co.uk, Google looks for what site ranks best and then looks to see if there is an alternative it should swap out in its place.
So if you had some shares on one and some shares on another it would be less powerful than all on one site combined.
Hope that makes sense?

Redirecting old mobile site
Hi All, Trying to figure out the best option here. I have a website that used to utilize a separate mobile site (m.xyz.com) but now utilizes responsive design. What is the best way to deal with that old mobile site? De-index? 301 redirect back to the main site in the rare case someone finds the m. site somewhere? THanks! Ricky

Mobile Site Annotations
Our company has a complex mobile situation, and I'm trying to figure out the best way to implement bidirectional annotations and a mobile sitemap. Our mobile presence consists of three different "types" of mobile pages: Most of our mobile pages are mobile-specific "m." pages where the URL is completely controlled via dynamic parameter paths, rather than static mobile URLs (because of the mobile template we're using). For example: http://m.example.com/?original_path=/directory/subdirectory. We have created vanity 301 redirects for the majority of these pages, that look like http://m.example.com/product that simply redirect to the previous URL. Six one-off mobile pages that do have a static mobile URL, but are separate from the m. site above. These URLs look like http://www.example.com/product.mobile.html Two responsively designed pages with a single URL for both mobile and desktop. My questions are as follows: Mobile sitemap: Should I include all three types of mobile pages in my mobile sitemap? Should I include all the individual dynamic parameter m. URLs like http://m.example.com/?original_path=/directory/subdirectory in the sitemap, or is that against Google's recommendations? Bidirectional Annotations: We are unable to add the rel="canonical" tag to the m. URLs mentioned in section #1 above because we cannot add dynamic tags to the header of the mobile template. We can, however, add them to the .mobile.html pages. For the rel="alternate" tags on the desktop versions, though, is it correct to use the dynamic parameter URLs like http://m.example.com/?original_path=/directory/subdirectory as the mobile version target for the rel="alternate" tag? My initial thought is no, since they're dynamic parameter URLs. Is there even any benefit to doing this if we can't add the bidirectional rel="canonical" on those same m. dynamic URLs? I'd be immensely grateful for any advice! Thank you so much!

GoogleBot Mobile & Depagination
I am building a new site for a client and we're discussing their inventory section. What I would like to accomplish is have all their products load on scroll (or swipe on mobile). I have seen suggestions to load all content in the background at once, and show it as they swipe, lazy loading the product images. This will work fine for the user, but what about how GoogleBot mobile crawls the page? Will it simulate swiping? Will it load every product at once, killing page load times b/c of all of the images it must load at once? What are considered SEO best practices when loading inventory using this technique. I worry about this b/c it's possible for 2,000+ results to be returned, and I don't want GoogleBot to try and load all those results at once (with their product thumbnail images). And I know you will say to break those products up into categories, etc. But I want the "swipe for more" experience. 99.9% of our users will click a category or filter the results, but if someone wants to swipe through all 2,000 items on the main inventory landing page, they can. I would rather have this option than "Page 1 of 350". I like option #4 in this question, but not sure how Google will handle it. http://ux.stackexchange.com/questions/7268/iphone-mobile-web-pagination-vs-load-more-vs-scrolling?rq=1 I asked Matt Cutts to answer this, if you want to upvote this question. 🙂

Duplicate Content Question
We are getting ready to release an integration with another product for our app. We would like to add a landing page specifically for this integration. We would also like it to be very similar to our current home page. However, if we do this and use a lot of the same content, will this hurt our SEO due to duplicate content?

Followup question to rand(om) question: Would two different versions (mobile/desktop) on the same URL work well from an SEO perspective and provide a better overall end-user experience?
We read today's rand(om) question on responsive design. This is a topic we have been thinking about and ultimately landing on a different solution. Our opinion is the best user experience is two version (desktop and mobile) that live on one URL. For example, a non-mobile visitor that visits http://www.tripadvisor.com/ will see the desktop (non-responsive) version. However, if a mobile visitor (i.e. iOS) visits the same URL they will see a mobile version of the site, but it is still on the same URL There is not a separate subdomain or URL - instead the page dynamically changes based on the end user's user agent. It looks like they are accomplishing this by using javascript to change the physical layout of the page to match the user's device. This is what we are considering doing for our site. It seems this would simultaneously solve the problems mentioned in the rand(om) question and provide an even better user experience. By using this method, we can create a truly mobile version of the website that is similar to an app. Unfortunately, mobile versions and desktop users have very different expectations and behaviors while interacting with a webpage. I'm interested to hear the negative side of developing two versions of the site and using javascript to serve the "right" version on the same URL. Thanks for your time!

SEOMOZ Diagram question
Hi, On this SEOMOZ help page (http://www.seomoz.org/learn-seo/internal-link) the diagram explaining the optimal link structure (image also attached) has me a little confused. From the homepage, if the bot crawls down the right-hand link first, will it not just hit a dead end where it cant crawl any further and disappear? OR... will it hit the end of the structure and then crawl backwards to the homepage again and follow down another link and then just repeat the process until all pages are indexed? Cheers pyramid.jpg

HTML entities and SEO
I recently came across an article on HTML entities that discussed how their appear in search results. The same article also mentioned that their use might be considered spam. Since I know nothing of them (other than what I read in the one article) are they a good or bad idea to make meta descriptions stand out from the crowd?
