Native assembly renderer best practices

  • Articolo

The Renderer tab stores the HTML, CSS, and Javascript code associated with the native assembly. Any changes made on the Renderer tab will automatically be reflected in the Preview window.

Here's a list of tips and important notes related to the Renderer tab that you should keep in mind:

  • If you removed any of the existing standard and custom creative asset specifications on the Setup tab, the HTML code on the Renderer tab won't automatically reflect this change, so manually remove the corresponding HTML and/or placeholders from the HTML text box on the Renderer tab.

  • Ensure that the [%impressionTrackers%] object placeholder appears in the HTML field or Javascript field on the Renderer tab. If it doesn't, you'll have to manually add it so that impression trackers can be tracked. If your renderer or website uses another impression tracking method, you don’t have to add the [%impressionTrackers%] object placeholder to the HTML field or Javascript field. However, when saving your native assembly, a warning dialog will appear where you can select the I will manage my impression trackers from my own website checkbox, which gives you the ability to save the native assembly without adding the [%impressionTrackers%] object placeholder.

  • Adding <script> tags directly in the HTML text box won't work. You must use the designated Javascript text box to write js code. The Javascript text box doesn't require the user to use HTML <script> tags.

  • Following IAB's standard for video creatives, by default, native videos will play when the user clicks the play button. If you want the video to play automatically with the audio muted, remove the // from these commented lines under function vidCallback() in the Javascript text box on the Renderer tab:

    //initialPlayback: 'auto',
//initialAudio: 'off'
