Google Analytics提供了强大的API来跟踪搜索引擎，下面用鲜果网的自定义代码来说明，打开鲜果网的首页，能看到这样一段代码：
var t = _gat._getTracker("UA-9142976-1");t._addOrganic("baidu","word");t._addOrganic("soso","w");t._addOrganic("3721","name");
t._addOrganic("yodao","q");t._addOrganic("vnet","kw");t._addOrganic("sogou","query");t._addIgnoredOrganic("鲜果");
t._addIgnoredOrganic("鲜果网");t._addIgnoredOrganic("xianguo");t._trackPageview();return t;
} catch(err) {}
定义柱状图的示例：
// somewhere at the top of the page
var timeTracker = new TimeTracker();
timeTracker._recordStartTime();
// page load and setup
// now when the page is done loading...
timeTracker._recordEndTime();
// Specify your own histogram "action" values
timeTracker._setHistogramBuckets([10, 20, 50, 100, 500, 1000]);
// assuming pageTracker is called from _gat._getTracker(account)
timeTracker._track(pageTracker);
示例：
// We want to track mouse overs on a video unit that has the element id "myVideoUnit".
// assuming pageTracker is called from _gat._getTracker(account)
var mouseOverTracker = new MouseOverTracker(pageTracker);
document.getElementById("myVideoUnit").onMouseOver = mouseOverTracker._trackMouseOver;
