Add key-value pairs to a master video tag

Key-value pairs enable you to set specific targeting, such as demographics, certain spots on a webpage, or a particular page or pages on a given topic.

It currently isn't possible to add key-value pairs to master video tags within the DFP interface, but we're working on adding this functionality. In the meantime, you can manually add key-value targeting by using the keyword cust_params.

To add custom targeting to your video ad tag, follow these steps:

  1. Identify the key-value pairs you want to use in your ad tag. When a key has multiple values, use a comma (,) to separate the values. In this example, we use the key-value pairs section=blog and anotherKey=value1,value2.

  2. Combine all key-value pairs with the "&" character.

    section=blog&anotherKey=value1,value2

  3. Encode the following characters:

    Character Encoded value
    = %3D
    & %26
    , %2C

    section=blog&anotherKey=value1,value2
    becomes
    section%3Dblog%26anotherKey%3Dvalue1%2Cvalue2

  4. Set the value in Step 3 as the cust_params keyword.

    cust_params=section%3Dblog%26anotherKey%3Dvalue1%2Cvalue2

  5. Add the "&" character to the beginning and end of the value in Step 4 to separate it from the other targeting information in the tag.

    &cust_params=section%3Dblog%26anotherKey%3Dvalue1%2Cvalue2&

  6. Add the value in Step 5 to the original master video tag:

    Original tag:

    http://pubads.g.doubleclick.net/gampad/ads?
    sz=400x300&
    gdfp_req=1&
    iu=/6062/videodemo&
    ciu_szs=728x90,300x250&
    url=http://www.simplevideoad.com&
    correlator=7104&
    env=vp&
    unviewed_position_start=1&
    output=xml_vast2&
    impl=s
    

    New tag with custom targeting:
