System maximums and limits

DFP enforces various limits and maximums on the entities you create. Keep the following limits in mind when setting up your inventory and orders.

Inventory

Ad unit codes
Ad unit codes can be up to 100 characters in length and must be unique. Only letters, numbers, underscores, hyphens, periods, asterisks, forward slashes, backslashes, exclamation marks, left angle brackets, colons and parentheses are allowed.

Placements:

  • Ad units per placement: 1000
  • Active placements per network: 60,000. This limit is a safeguard and can be increased if you are nearing the threshold. Contact your DoubleClick representative to request an increase to this limit.

Exclusions: 
Ad units per ad exclusion: 1000

Keys-values
  • Characters per key: 20
  • Characters per value: 40
  • Active values per network: 2,500,000
  • Active keys (free-form and pre-defined) per network: 200
  • Active values (free-form and pre-defined) per key: 100,000
Deactivated key-values do not count toward their respective limits.

An ad request URL has a character limit, depending on the tag type, which may limit the number of key-values.

Google Publisher Tags use the HTTP GET method to request ads, which limits the number of bytes that can be passed with each request. Ad tags using synchronous rendering are limited to 2048 characters per request. However, if the tag type is asynchronous and exceeds 2048 characters, GPT automatically uses the POST method, which increases this limit to 8192 characters.*

* The character limit increase with the POST method does not apply to ads rendering in IE versions 9, and below.

Trafficking

Orders
Line items per order: 450 (regardless of status, including archived line items)

Line items

  • Active line items: 61,000. An active line item:
    • is capable of being delivered
    • has a status of “ready” or “delivering”
    • has start date of today or earlier
    • has an end date of today or later
  • Creatives per line item: 260
  • Total line items per network: 600,000. This limit is a safeguard and can be increased if you are nearing the threshold. Contact your DoubleClick representative to request an increase to this limit.
  • Targeted criteria per line item: 800 More information on the targeted criteria limit

    In general, what you see in the targeting expression counts toward the limit. A few notes on more complex targeting:

    • Placement Targeting: Each placement counts as one targeting criteria, even if the placement itself contains more than one ad unit.
    • Day/Time targeting: If you are using day/time targeting, the contiguous active blocks for each day of the week count as one criteria toward the total targeting criteria limit.

      If you had a line item running from 3pm-7pm each day, It would count as 7 targeting criteria (one targeting parameter times seven days). If you had a line item with 11am-1pm and 2pm - 5pm blocks on weekdays, it would count as 10 targeting criteria (2 active blocks for each day of 5 days).

    • Frequency capping: Does not count toward the targeting criteria limit.
    • Custom Criteria: Each key-value pair counts as one targeting criteria toward the limit. If the expression uses match types, like key is not ~value*, each key to match type value is counted as one targeting criteria toward the limit.

    Let’s look at two examples with the following targeting:

    Example 1

    • Line item targeting:

      • Ad Unit: 300x250Web
      • Custom Criteria: (cat=Education AND art_id=123) OR color=blue OR env=test OR clubcode=XYZ
      • Geography: United States
    • Count:
      Ad Unit (1) + Custom Criteria (5) + Geography (1) = 7 targeted criteria

    Example 2

    • Line item targeting:

      • Placement: BannerROS
      • Custom Criteria: (cat=Education OR cat=Sports OR cat=Business) AND (color=blue OR color=green) AND (topic is not ~politics*)
      • Day/time: 3pm-7pm each day of the week
    • Count:
      Placement (1) + Custom Criteria (6) + Day/Time (7) = 14 targeted criteria

  • Characters per line item name: 255

Creatives
Creative asset size: 1 million bytes

Limits on rapid creation

DFP monitors networks to ensure that technical glitches aren't causing runaway creation of orders, line items, creatives, ad units, placements, or advertisers. In such cases, to protect your network, DFP places a temporary limit on the creation of new items.

For example, if an external program that uses the DFP API to connect to your network is creating thousands of new orders in a very short time period, it's probably an error. These temporary limits can be imposed even if the rapid creation hasn't violated any of the numerical limits listed above. We'll work with you to resolve the problem and get your network back in working order.
