Measure your marketing performance.
ANALYTICS PROVIDE CRITICAL DATA ABOUT YOUR AUDIENCE behavior, blending online and offline campaigns and response mechanisms for complex data analysis and reporting. Google Analytics is a free platform that allows you to benchmark your traffic, and monitor growth precisely. Understand visitor demographics and traffic paths within your site. Measure conversions, and track them back to the source to know which campaigns are performing and which are not.
MAKE SURE YOUR ANALYTICS account is properly set up to capture all the data you need, and make a point of regularly reviewing the metrics, comparing to past performance benchmarks to measure improvements. Google provides astonishingly powerful and accurate reporting tools for free, and the data -- particularly goal achievement -- can close the loop to inform Google's organic search rank.
