There is so much data that you can gather to market via this avenue that it means you can make your message extremely relevant to the individual or company. Often you can find out peoples locations, times that they use their phone most, products / pages that they have viewed. Many of the big search engines already show users a personalised view of a search results page changing the position and ads shown to match those that may be of interest to you based on previous searches.
