Google’s search results are device-dependent, meaning that the device you use to search Google will influence the results that are shown to you:
Not everyone realizes it, but Google has been serving different search results to mobile phones than desktop computers for a long time. Beyond that, they serve different results based solely on the handset you are using to search. The differences are often subtle, or focused on the order of Universal Results that are included in the mobile result-set, but Google is algorithmically trying to prioritize content that will work well on the phone that submitted the query, and give less priority to content that might not work on the phone.
And the differences are going to be even more pronounced:
Now Google has launched a new smartphone crawler, and this will likely push the differences between desktop search and mobile search more into the mind of the average SEO.
As a business owner, you have to make sure that your online marketing strategy is keeping up with with the changing landscape of search engines. If your business relies on Google to send you customers, it’s in your best interest to understand what Google is doing, especially related to the mobile web, which is evolving rapidly at this early stage.
