You’re right and that’s specifically our point. In the end it depends on what more important to track. This is certainly a method to get product abandonment reports in Google Analytics but because of the bounce rate consequences it’s not for everyone.

Bounce rate can be effected when adding event tracking, but this is not always bad. The way it works is that an event is seen as an interaction, and therefore it is not a bounce when a visitor visits a page, interacts with the site (which triggers an event) and then goes away.

This is good when you have an interactive site where visitors can do all their interactions on one page (e.g. for a Flash, Ajax site) or when you have a a product page that consists of several views that do not require a page reload. Now this page will not show a high bounce rate when visitors are interacting with the site before leaving.

This is bad when event tracking is used for automatic tracking of events such as page load time. In that case bounce rate for all pages would go down (or even become 0%) because there always is interaction with the page even though automatic.

So be careful when adding event tracking that gets triggered without user interaction, it might screw up your bounce rate figures .

I have one comment on your article though:
Event tracking does not register page views, so you can use it without messing up your overall page views, pages per visit and bounce rates
