According to Y.M. Ousley it's simple: Choosing to focus the bulk of its resources on
core search has left the search giant in a slightly weaker position when it comes to other verticals. So while Google may make advancements with travel search, engines like SideStep or Kayak that can
provide pricing and seat info will win out every time.
It's in these vertical areas that the "other" search engines can maintain (or attain) the top spot for search volume and user preference - and, depending on their niche, where search marketers should devote additional time and resources to snagging top rankings.
