Any Size

Banners can be linked disregarding of their sizes. Epom Ad Server will choose a fitting Banner among the linked ones. Banner height and width should be passed as Custom Parameters in the Invocation codes (%CUSTOM_WIDTH% and %CUSTOM_HEIGHT% placeholders should be replaced with supp_custom_params={width:'300',height:'250'}; string, for example)

Flexible Placement Size: This checkbox identifies if the Ad Units (Banners) that are smaller than the Placement size can be linked to the Placement.

Default Code: In case there is no Placement that would fit a certain user, the default code will be displayed. The Impression won't be counted towards Epom Analytics.

Invocation codes / HTML Samples

An Invocation Code is an ad tag, which invokes (calls) Epom Ad Server to deliver ads. It should be inserted into the web-pages of your site where you would like the ads to be displayed. The set of available codes depends on the Placement type.
