Make it a regular task to view your visitor traffic stats and analyze your performance (provided that you have previously installed Web Analytics on your blog). Learn how many readers visit your blog daily, which referring sites send you the best traffic, see which keywords have the highest engagement, and more.
Apart from traditional web analytics stats, it is also good to analyze the social engagement of your blog readers: track RSS views, blog post views, comments, Google trackbacks, Twitter and Jaiku mentions, number of Twitter followers, Facebook Shares and Likes, social bookmark saves, votes on
social recommendation sites like Digg, Reddit, Newswine, etc.
You can either track these factors by hand, or use a paid tool, e.g. PostRank Analytics. PostRank Analytics is a cost-effective solution that measures the social engagement of your blog readers and presents the data in a comprehensive and neat manner. PostRank Analytics can be seamlessly integrated with Google Analytics, so you will be able to track regular visitor stats and social engagement stats using one interface.
