What are custom ad serving settings and variables?

These are additional settings available to the serving code for advanced functionality.

Custom Parameters

You can enter one of the following values, without the quotes, into the "Custom Parameters" field when generating the serving code. For example:

• &dim=0x0x4|120x300x2|120x600 serves ads of multiple dimensions together, including text ads and banners
• &keywords=garden+vegetables applies keyword targeting
• &wmode=transparent changes WMODE setting
• &custom=Custom+Ad+Data to pass custom/dynamic data to your ad
• &cb=[cachebuster]&r=[ENCODED_CLICK_REDIRECT_MACRO] for a click macro

Pass-along Parameters

You can pass a variable into our ad tag and we will pass that variable to the ad. This is useful when the ad displays dynamic content based on certain input. For example, an ad displays today's interest rate for a mortgage loan that need the actual interest rate supplied from outside. Learn more
