Kontera offers two tools to help you specify which areas on your site's pages will be analyzed.

Zone Tags tell our JavaScript which areas to analyze. They are useful in keeping our ads out of navigation bars, headers, footers and titles. Zone Tags can be used multiple times on any given page. When employing Zone Tags please ensure that each tag is opened and closed separately. 
 
Filter Tags are used in order to define an area of the page where Kontera ads should not appear. All other areas of the page are valid highlight areas. Please use Filter Tags with caution in order to prevent unintentional exclusion of large areas.
 
Using Zone and Filter Tags to block ads from appearing on your site's headers, footers, and sidebars ultimately improves your overall CTR and eCPM.
