What Happened
In response to the fact that over half of Google searches now come from a mobile device, Google is set to create a mobile index separate from its existing search index within months. The new mobile index will become the primary index that responds to search queries. A desktop index will be maintained, but not as up-to-date as the mobile index.
Why Brands Should Care
For now, it is unclear how the mobile index will be set up as Google has yet to announce any details on the matter. But it seems safe to assume that mobile-friendly sites will receive preferred rankings in the search results. As Google’s plan for the mobile search index unfolds in the following months, brands will need to keep a close eye on this development and adjust their SEO campaigns accordingly.
