What is a Google Event?
Events are user interactions with content that can be measured independently from a web page or a screen load.
Downloads, social share, click to call, mobile ad clicks, gadgets, Flash elements, AJAX embedded elements, video plays and othe UI elements are all examples of actions you might want to measure in your Analytics account as Events.
An event hit includes a value for each component, and these values are displayed in your Analytics reports: Category, Action, Label (optional, but recommended) and Value (optional).
When a user clicks a link that points to another page on your site, that page typically sends a pageview hit as the user arrives.
Because there's a series of pageviews, Google Analytics can figure out on the back end where the user navigated to (and from). But if a user clicks a link or submits a form to an external domain, that action is not captured unless you specifically tell Google Analytics what happened.
Fortunately, there is Google Event builder, a tool by dunplab made for develpers who like to know more and optimize Analitycs data.
