When creating flash banners it is necessary that the banner's destination (click-through) url is not physically hard coded into the SWF file, otherwise click counting will not be possible. Instead, the "clickTag" variable should be used. The value of this variable can then be handed over to the flash banner by the ad server.
To implement the clickTag click counting method in your flash creative, simply insert a new top-layer button in the clickable area and add the following action:
on (release) {
getURL (clickTag, "_blank");
}
It should look something like the below :-
The process is almost the same for flash creative which contains multiple clickable zones with different destination urls. Follow the procedure outlined above, but instead of clickTag use clickTag1, clickTag2, clickTag3, etc for each clickable area.
