Because of the fact that tracking of clicks on an advert is a mandatory task,WPBanner do tracking for you using an internal tracker.
Click tracking for adverts gives you an indication of how well an ad is performing.
The visitor clicks on the banner/ad and through jQuery the click info is sent to server with the Ajax request in the background. This works perfectly transparent.
You can always see the stats of clicks for every advert in the statistics option in admin panel.
Note: Plugin does not count clicks for ad networks like Google AdSense. So, no increase in click stats.
WPBanner also do the impression tracking for the banner/ad.
When ever a banner/ad is shown to the user, it is termed as an impression.
Every time a banner/ad is shown to the client. It got logged into the stats.
Clicks/impressions tracking for each banner/ad is enabled individually with a click. No additional configuration is required.
As a result of tracking, stats are generated for each banner/ad.
