How do I ensure my buying premium placements with a private marketplace is compliant?

To help ensure premium placement buys through a private marketplace (PMP) are compliant, focus on three layers: legal/regulatory, platform/vendor, and internal governance.

1) Confirm what you’re buying is allowed

• Inventory legitimacy: Verify the publisher, app, or site is real and authorized to sell the placement.
• Premium placement definition: Make sure the placement is clearly described in the deal terms (e.g., homepage takeover, above-the-fold, native unit, rewarded video).
• No prohibited content: Check whether the placement appears alongside restricted categories (adult, gambling, misinformation, illegal goods, etc.) that violate your brand or local laws.

2) Ensure data and targeting comply

If the PMP uses audience data, make sure you have:

• Consent/legitimate basis for tracking and targeting where required (e.g., GDPR/UK GDPR, ePrivacy, CCPA/CPRA).
• Contractual coverage with the DSP, SSP, publisher, and any data providers.
• Data minimization: Only use the data needed for the campaign.
• Sensitive data restrictions: Avoid using or inferring sensitive categories unless you have explicit permission and a lawful basis.

3) Validate the deal structure

Review the insertion order / deal ID / agreement for:

• Price, floor, and delivery terms
• Viewability, completion rate, or placement guarantees
• Ad format specs
• Brand safety and fraud protections
• Right to audit, make-goods, and cancellation terms
• Who is the seller of record and who is responsible for taxes, invoicing, and reporting

4) Check competition and media-buying rules

Depending on your market and industry, ensure compliance with:

• Advertising disclosure rules for native/sponsored content
• Industry-specific rules (finance, alcohol, health, politics, children’s advertising)
• Anti-bribery / conflict-of-interest policies if the placement is negotiated directly or with special access
• Competition/antitrust concerns if the deal includes exclusivity or preferential access

5) Maintain brand safety and fraud controls

Use verification and monitoring for:

• Invalid traffic / ad fraud
• Viewability
• Domain/app verification
• Geo-targeting accuracy
• Placement adjacencies and content category blocking

6) Keep documentation

Maintain records of:

• Contract/MSA/IO
• Deal ID and screenshots or placement descriptions
• Consent logs or vendor data-processing terms
• Due diligence on publisher and intermediaries
• Compliance reviews and approvals
• Delivery and performance reports

7) Use a compliance checklist before launch

A practical pre-launch checklist:

• Publisher verified
• Placement and format documented
• Legal/privacy review completed
• Data-sharing and consent rights confirmed
• Brand safety settings applied
• Fraud/IVT protections enabled
• Industry-specific ad rules checked
• Internal approvals obtained
• Audit trail stored

8) Get local legal review for high-risk campaigns

You should get counsel involved if the buy involves:

• Children or teens
• Health, pharmaceuticals, supplements
• Financial products or claims
• Alcohol, gambling, cannabis
• Political or issue advocacy
• Cross-border targeting or data transfers

If you want, I can turn this into a one-page compliance checklist or tailor it to a specific region (e.g., US, EU, UK) or ad category (finance, healthcare, alcohol, etc.).
