The bounce rate on my site has gone from above 75% to about 2%. http://www.encognitive.com/bounce-rate.png

I researched I found that event tracking can affect google analytics bounce rates. I was wondering if jQuery has anything to do with it as I'm seeing this code that may be related to even tracking in the page source:

jQuery.extend(Drupal.settings, { "basePath": "/", "googleanalytics": { "trackOutgoing": 1, "trackMailto": 1, "trackDownload": 1, "trackDownloadExtensions": "7z|aac|arc|arj|asf|asx|avi|bin|csv|doc|exe|flv|gif|gz|gzip|hqx|jar|jpe?g|js|mp(2|3|4|e?g)|mov(ie)?|msi|msp|pdf|phps|png|ppt|qtm?|ra(m|r).....

From google analytics support page:

In general, a "bounce" is described as a single-page visit to your site. In Analytics, a bounce is calculated specifically as a session that triggers only a single GIF request, such as when a user comes to a single page on your website and then exits without causing any other request to the Analytics server for that session. However, if you implement Event Tracking for your site, you might notice a change in bounce rate metrics for those pages where Event Tracking is present. This is because Event Tracking, like page tracking is classified as an interaction request.

For example, suppose you have a page with a video player where the bounce rate is historically high, and you have not implemented Event Tracking for the page. If you subsequently set up Event Tracking for the player, you might notice a decrease in the bounce rate for that page, because Analytics will record user interaction with the player and send that interaction to the server as an additional GIF request. Thus, even though the same percentage of visitors to the page might still exit without viewing any other page on your site, their interaction with the video player triggers Event Tracking calls, which disqualifies their visit as a bounce.

In this way, "bounces" for your event-enabled pages means something slightly different: a single-page visit that includes no user interaction on tracked events.

It's important to keep in mind that any implementation of Event Tracking that automatically executes on page load will result in a zero bounce rate for the page. This is the case if you implement the TimeTracker example, or any other similar Event Tracking utility
