Understanding fees for using segments

Marketplace Partners
Last Updated: October 26, 2026•

When you create a Marketplace Package, you can choose to target segments in the deal. In addition to your own data, you can also use publicly available third-party segments or custom segments that a Data Vendor has provided to you. When an impression occurs, the Data VendorClosed A type of Marketplace Partner that owns data segments that can be used by Index customers for a fee. may collect a fee called a Marketplace Vendor Fee for the use of these segments. Marketplace Vendor Fees are included in the total Marketplace fees applicable to the transaction. To learn how Marketplace Vendor Fees work with your revenue share and other fees, see Understanding vendor fees for Marketplace Partners.

If a segment has a fee, you can see the fee amount when you select the segments to target in a Marketplace Package, as shown in the following screenshot:

A segment fee can be a fixed CPMClosed Cost Per Thousand (CPM). A pricing structure for buying impressions and is the cost of serving an advertisement 1,000 times. Also known as Cost Per Mille (where M represents 1,000 in Roman numerals) or Cents Per Mille. or a % of media. A % of media may also show an Up to CPM amount, which is the most the fee can be per thousand impressions. The total fee depends on the number of segments that have activated the dealClosed A private auction that allows media owners to offer specific inventory directly to selected buyers identified by a deal ID. Terms are negotiated and are agreed upon before the auction occurs. and the number of different Data Vendors who own the segments. If multiple segments have activated the deal, only the highest fee for each Data Vendor is applied.

The following explains how vendor fees are applied in various scenarios, assuming a $10.00 Marketplace Media Spend:

Segments active on the dealHow it worksTotal fee applied

Data Vendor A

Segment 1: $1.00 CPM

A single segment from Data Vendor A has activated the deal, so just the fee for this segment is applied.

$1.00

Data Vendor A

Segment 1: $1.00 CPM

Segment 2: $2.00 CPM

Two segments from Data Vendor A have activated the deal. The highest fee is applied because both segments are from the same Data Vendor.

$2.00

Data Vendor A

Segment 1: $2.00 CPM

Segment 2: $2.00 CPM

Two segments from Data Vendor A have activated the deal. When both segments have the same fee and belong to the same Data Vendor, one segment's fee is randomly selected and applied.

$2.00

Data Vendor A

Segment 1: $1.00 CPM

Data Vendor B

Segment 1: $1.00 CPM

One segment from Data Vendor A and one segment from Data Vendor B have activated the deal. Both segment fees are applied because each Data Vendor collects their own fee.

$2.00

Data Vendor A

Segment 1: $1.00 CPM

Segment 2: $2.00 CPM

Data Vendor B

Segment 1: $1.00 CPM

Segment 2: $2.00 CPM

Two segments from Data Vendor A and two segments from Data Vendor B have activated the deal. The highest fee for each Data Vendor is applied.

$4.00

Data Vendor A

Segment 1: 6% of media, capped at $0.40

A single segment from Data Vendor A has activated the deal. The segment's fee is 6% of the $10.00 Marketplace Media Spend, which is $0.60. Because this exceeds the $0.40 maximum, the fee is capped at $0.40.

$0.40

Data Vendor A

Segment 1: $0.30 CPM

Segment 2: 5% of media

Two segments from Data Vendor A have activated the deal. The highest fee applies, regardless of fee type. Segment 2's fee is 5% of the $10.00 Marketplace Media Spend, which is $0.50. This is higher than Segment 1's fee of $0.30.

$0.50

Data Vendor A

Segment 1: $1.00 CPM 

Data Vendor B

Segment 1: 4% of media

A single segment from Data Vendor A and another from Data Vendor B have activated the deal. Both fees are applied because each Data Vendor collects their own fee. Data Vendor A's $1.00 and Data Vendor B's $0.40 are both applied.

$1.40

Note: You are never billed for targeting your own segments.
