TL;DR: A CTV media buying mandate is more specific than a general display mandate. It needs to define which broadcaster and content categories the brand will appear against, what CPM ceilings apply by category, what audience data permissions the agent holds for CTV targeting, and what approval thresholds govern deals above defined budget levels. The most common gaps in CTV mandates in practice are missing content adjacency parameters and undefined completion rate floors.

A mandate is the human-approved governance document that defines the parameters within which a buy-side agent can agree a deal. It is not a set of platform targeting settings. It is a documented decision about what the agent is authorised to do, made before the agent begins any negotiation.

For general display or online video inventory, a mandate might specify CPM ceilings, audience parameters, and placement exclusions. For CTV inventory, those parameters are necessary but not sufficient. CTV has specific characteristics that require additional mandate elements: the content adjacency requirements of premium broadcasting, the CPM variation between content categories, the targeting conditions that CTV publishers accept, and the completion rate standards that define viewable CTV delivery.

Broadcaster and Content Category Parameters

The most important CTV-specific mandate element is the definition of which content categories the brand will and will not appear against. CTV advertising is delivered against specific programming. The brand risk associated with a misplaced ad in a live news context is different from the risk in a drama or children's programming context.

A CTV mandate should specify:

Approved content categories. Which categories the agent can negotiate inventory against. Live sport, drama, entertainment, factual, news, children's programming. If the mandate does not list approved categories explicitly, the agent has no basis for declining a proposal that falls outside what the brand actually wants.

Excluded content categories. Which categories are an unconditional exclusion, regardless of CPM. News adjacency may be an exclusion for some brands regardless of price. Children's programming may require a specific brand approval before any deal can be agreed.

Broadcaster restrictions. Whether there are specific broadcasters the brand will not appear on, regardless of content category.

CPM Ceiling by Content Category

A single CPM ceiling for all CTV inventory creates a problem: it either excludes premium inventory that the brand should be on, or it overpays for lower-value inventory. CTV CPMs vary significantly by content category and daypart. Live sport commands a different CPM from a drama on-demand. News adjacency may sit at a different floor from entertainment.

A well-written CTV mandate defines a CPM ceiling per content category, not a single ceiling across all CTV. The agent applies the relevant ceiling to each proposal it evaluates. A proposal for live sport inventory is evaluated against the live sport ceiling, not the general ceiling.

This requires the buying team to have a view on CPM benchmarks by content category before writing the mandate. A mandate written with a single ceiling because the team has not benchmarked category CPMs is a mandate that will underperform.

Audience Data Permissions

CTV targeting works differently from display targeting. Audience data permissions in a CTV mandate need to specify which data sources the agent can use when evaluating or proposing audience conditions, and what the brand's position is on publisher-shared audience data.

Some CTV publishers offer their own first-party audience data as part of a deal. The mandate should specify whether the agent is permitted to accept deals that include publisher audience data conditions, and under what terms.

Completion Rate and Viewability Requirements

CTV inventory is delivered as long-form video advertising. The standard completion metric is the completion rate: the percentage of impressions where the viewer watched the full ad. A CTV mandate should specify a minimum acceptable completion rate, below which the agent should not agree a deal.

Minimum viewability conditions also apply, though CTV has different viewability standards from display. The mandate should be explicit about which standards apply.

Daypart Restrictions

Some brands have daypart restrictions for CTV advertising: no advertising before a certain time, no advertising in late-night slots. These restrictions may exist for brand, audience, or regulatory reasons. A CTV mandate should state daypart restrictions explicitly so the agent can apply them to every proposal it evaluates.

Approval Thresholds

Every mandate needs approval thresholds: the budget levels above which the agent must escalate to a human before agreeing a deal. For CTV, where individual deals can represent significant budget commitments, these thresholds matter.

A common gap in practice is a mandate with content category parameters and CPM ceilings, but no defined approval threshold for large deals. The agent operates under the mandate parameters and agrees a deal that is within the CPM ceiling but above a budget level that the human team would have wanted to review. The deal is not outside the mandate in terms of price, but it is outside the scale of deal that the human team intended to delegate.

The Most Common CTV Mandate Gaps

In practice, three gaps appear most frequently in CTV mandates. First: missing content adjacency parameters, leaving the agent without a basis for declining proposals that fall outside acceptable content categories. Second: a single CPM ceiling across all CTV rather than ceilings by content category, leading to either overpaying for lower-value inventory or missing premium deals. Third: undefined approval thresholds for large deals, meaning the agent can agree budget commitments at a scale the human team did not intend to delegate.

A CTV mandate that addresses all three gaps is not significantly more complex to write than a general display mandate. It requires the buying team to have done the category benchmarking and the budget governance work before the agent begins negotiating. That preparation is the work of mandate governance.
