Rimm-Kaufman Group released its RKG Digital Marketing Report for Q4 2011 this week. It offers insight and analysis for paid search, SEO and social marketing. For example, the report explains that paid-search ad spend rose 31% year-over-year in Q4 among Rimm-Kaufman clients -- a trend that most companies in the search industry experienced. The report highlights obvious and overlooked trends, such as an increased focus on automation capabilities in AdWords. Another interesting insight remains the decline of cost per click in Google AdWords. The report suggests a decline of CPCs on Google of 5.2%, something the search engine has not reported in eight quarters.
