Netflix Ads via Microsoft: The Ultimate CTV Guide (2026)

Microsoft is the exclusive ad technology partner for Netflix. If you want to reach the Ad-Supported Tier (20M+ users), you go through Microsoft Invest (DSP) or the Microsoft Advertising platform.

In this "Mega-Authority" guide, we cover:

1. Access: Managed Service vs Self-Serve.
2. Video Specs: High fidelity required.
3. Targeting: Genres and Top 10.
4. Measurement: Reach & Frequency.

Part 1: Access Levels

• Small Biz: Ads appear on Netflix via the "Audience Network" (Video Extension). You have little control.
• Enterprise: You use Microsoft Invest (Xandr). This is a robust DSP. You can select "Netflix" inventory specifically.
• This guide focuses on the standard Ad Platform access.

Part 2: Launching a CTV Campaign

1. New Campaign -> "Video" (or CTV).
2. Ad Group Settings: Edit Placements.
3. Targeting: Select "CTV" and "Premium Publishers."
4. Note: You cannot say "Only show on Stranger Things." You buy the "Netflix Network."

Part 3: Creative Specs

TV screens are big.

• Resolution: 1920x1080 (1080p) Minimum. 4K preferred.
• Length: 15s or 30s (Unskippable).
• Audio: Stereo (High quality mix).
• File Size: Up to 500MB.

Part 4: Frequency Capping

CTV ads can be annoying if shown too much.

• Rule: Set Frequency Cap to 2 per Hour and 4 per Day.
• Do not burn out your welcome in the living room.

Part 5: Summary & Checklist

Your Action Plan:

1. Produce a TV-quality 30s spot.
2. Create a "Connected TV" campaign in Microsoft Ads.
3. Target your core demographic (Age/Gender).
4. Measure "Video Completion Rate" (Should be > 95% on Netflix).

Primetime is yours.
