Mobile SERPS & Usability

The author's posts are entirely his or her own (excluding the unlikely event of hypnosis) and may not always reflect the views of SEOmoz, Inc.So here is the deal: Traditional websites frequently rank in mobile search results – especially if you are searching from a SmartPhone. What you may not realize is that the converse is also true – mobile pages can rank well in traditional search. This is quite an interesting phenomenon, and something that we need to address strategically.

All One Index Soon?

Why does this happen?

Well, Google has said that they really don’t want to index two versions of the web – one mobile and one traditional. Even though they do have different mobile-specific bots, they want those their bots all to feed into one index. Hmmmm….Is it just an interesting coincidence that they just launched the multi-format site mapping in Google, where you can combine all the different types of sitemaps that we previously had to submit separately? Possibly. At least it that could indicate a shift away from multiple indexes.

Did anyone notice that this shift happened pretty soon after Caffeine, as did the re-launch of Google Images, and some significant changes in Google Places?

Hmmmm…..It seems that Google might be moving away from having multiple indexes that must be queried for different types of content - like mobile, local, images, news, etc. to a 'one index' solution that has different types of ‘indexing attributes’ instead. That would actually do lots of things that Caffeine has done, like speed up searches (only need to query one index), and allow them to algorithmically prioritize things by freshness more effectively….

Different Indexes for Smart Phones and Feature Phones

But I have gone astray – We were talking about 'mobile'. We can’t know for sure if there are different mobile indexes. There definitely was a separate mobile index in the beginning of Google's ‘mobile’ search– you could always tell because the results were SO bad! Even in the past two years, I have seen mobile search results that were way off base – For example, the top result for a search on ‘subway sandwiches’ was a Gawker article for a long time; then Subway.com, and then m.subway.com. I just checked, and they have somewhat sorted that one out on smart phone searches, but it you still get weird results for feature phone search (shown below)! About 18 months ago Google changed the location of their mobile engine from m.Google.com to Google.com/m, and it did seem that the ‘/m’ feature phone search results were a bit better than they had been, but who knows!

As I have mentioned, there are different mobile search engine crawlers that are evaluating your website as if it was being rendered on a mobile phone. These mobile bots actually have both generic and specific user agent strings that will spoof actual phone handset models in order to understand how the website would render and function on the different phones. While they don’t do a great job, Google actually does try to only provide you with mobile search results that will actually work well on your particular handset – What that means is that there are slight variations on search results from phone to phone.

There are some simple ways to check what I am now describing as ‘mobile indexing attributes.’ I always start mobile rankings research by doing a ... Read more
