Zemanta Pixel is assigned to every Zemanta account by default. Using it is universal, which means that you can use one Zemanta Pixel on the account level for all top-down campaigns and ad groups. Being universal also means that you only need to install the pixel across your websites once, without implementing or updating the pixel again.
PLEASE NOTE: Your existing image pixels placed across your web pages are still fully functional and firing as conversion definitions.
Before you can add the pixel to your website, you'll need to have the ability to edit your website. Either you or your webmaster will need to be able to add the tag to your website code.
Since this is a universal pixel, there is no option to add new pixels or remove the existing ones. You will be able to track and attribute events and conversions for different scopes and campaigns by defining specific conversion definitions.
