Not every person who visits a Web site is actually looking to buy a product or initiate a sales call--many unique
visitors are researching for offline purchases, or just seeing what the market has to offer. But Webmasters can still calculate the value of these non-buyers by tracking their micro conversions--which
can be actions like reading the newest blog post, watching a product demo, checking out the careers section, or even searching for customer service info.
Kaushik lists some examples of which micro conversions to track and how to track them for ecommerce sites, blogs and other social media sites, and even a tech support Web site.
