An efficient way to analyze many aspects of your blog is to use a stat tracking tool. Such tools measure not only how many visitors come to your website, but also provide a lot of additional information like length of visit, geographical location, keywords used to reach the site, referring websites, and other data. Such information can be used in a multitude of ways, but let me give you an example. Let us say that you are analyzing keywords used by people using search engines to reach your site. Take notes of different terms being used to find your website and you will be often amazed how they reached you. Now that you know what the readers are interested in, you can even try to write posts on some of the topics that are related to the keywords being used, because you know that your readers have interest in it. Furthermore, one of the best aspects of such tracking tools is that most of them are completely free. What you should keep in mind that it may take some time to properly analyze all of the data. It is important not to make any hasty decisions based on your observations, and to take your time while studying the data.
