The credits are units that regulate the banner exchange between sites. For every two credits you earn, one of your banners will be shown. You can earn free credits by publishing Bannerlandia s banners in your site. For every banner you print, one credit will be added to your account. When a Internet user clicks a banner and is sent to the original site of this ad, then that is a click.
Ratio is the proportion between the times a banner is shown and the times users clicked on it.
The ratio is measured in percentage values. In that case, you should complete this form and in a few minutes you will receive a new one.
