Search volume based on trends is ever-changing. Twitter, YouTube and news aggregators are great resources for identifying popular trends. Take advantage of trends in your field as well as trends in business, technology, local, pop culture and world events to promote your product. You can garner significant web traffic by beating your competitors to the punch.
However, this does not mean you cannot topple them. It just takes more of an effort in terms of content as your page has to build the trust. That is why you will see the "Google dance" happening for fresh content from a site that is not yet trusted or is not very authoritative. Google gives your page a chance and measures user click-throughs when it pushes you to certain spots in the SERPs and then measures user engagement levels when the traffic hit your site through those positions in the SERPs.
