All Flash creative must be formatted to include at least one "click tag" command.

Click tags serve two key functions:

  1. They enable MediaNet® to track the number of clicks generated by your campaign and report on performance metrics like CTR (click-through ratio).
  2. They enable MediaNet® to link your ad to its landing page URL.

Action Script 1 & 2

Internet Explorer 8 Compliance

All Flash creative must comply with Internet Explorer 8 publish settings. You can check the publish settings your creative is using by browsing to the program menu and selecting File > Publish Settings > Flash tab. Make certain that your settings appear as follows:

Player: Flash Player 8
Script: ActionScript 2.0

If your creative is using legacy publish settings (i.e. Flash Player 7 or earlier, ActionScript 1.0), you can easily update them by re-encoding your file. Make sure you do this before implementing your click tag.


1. Create a full coverage transparent button

  • The top most layer of your ad must contain a transparent button that covers the entire scene.
  • You can make this button transparent by setting the top layer's Alpha value to 0%.
  • This full coverage transparent button represents the clickable area of your ad.

2. Incorporate the "Click Tag" into your transparent button

Now that you have created a button that will make the entire area of your ad clickable, you need to embed the click tag command into the button (which enables MediaNet® to link your ad to its landing page URL and track its performance).

Action Script 2.0 Language Reference

  • Specify a unique Instance Name in the Properties dialog for the transparent button you created in the top layer of your document. In the example below we used the name "clicktag_but".

  • Select a key frame in frame 1 from the timeline, then right click the frame (Ctrl-Mouse Click for OS X users) and choose Actions.
  • Enter the click tag code displayed in the Actions window (shown below) to implement the click tag command for your ad.

  • Additional click tags can be implemented using the same process; each button must have a unique instance name. The instance name must be updated in the Action Script code used for the button, along with an alternate value for clickTAG if a different URL is to be used. Multiple clickTAG parameters are incremented numerically as clickTAG1, clickTAG2, clickTAG3, etc.

Alternate Text

  • The URL you provide must be viewable in Microsoft Internet Explorer 3.0 and above and Netscape 4.0 and above.
