Creating YouTube video campaigns has always been a multi-step nightmare:

- Create or source video content
- Export in the right format and resolution
- Upload to YouTube manually
- Copy the video ID
- Navigate to Google Ads
- Create a Video campaign... wait, you can't via API
- Figure out Demand Gen campaigns instead
- Set up targeting, bidding, budget
- Create the video ad creative
- Launch and pray

**Now? One conversation.**

## What We Built

Synter now supports the complete YouTube advertising workflow:

### AI Video Generation

Generate video ads using Google Veo 3.1. Provide a concept, get a production-ready video.

### Ads-native Video Upload

Upload campaign videos through Google Ads without granting YouTube Data API or Drive access.

### Demand Gen Campaigns

Create campaigns that serve on YouTube, YouTube Shorts, Discover, and Gmail.

### Conversion Tracking

Set up Google Ads conversions and GTM tags automatically.

## Why Demand Gen, Not Video Campaigns?

Here's something Google doesn't advertise loudly: **The Google Ads API does NOT support creating Video campaigns.**

The API only allows *reporting* on existing Video campaigns. For programmatic YouTube ad creation, you must use **Demand Gen campaigns**.

### Demand Gen Campaign Placements

- **YouTube** — In-stream and in-feed video ads
- **YouTube Shorts** — Vertical video placements
- **Discover** — Google Discover feed
- **Gmail** — Promotions tab ads

We learned this the hard way so you don't have to. All our YouTube scripts use Demand Gen under the hood.

## End-to-End Workflow

### Step 1: Generate or Upload Video

Option A: Generate with AI (Veo 3.1)

```
"Generate a 15-second video ad showing our AI agent 
managing campaigns across multiple platforms. 
Dark tech aesthetic, cyan accents."
```

### Step 2: Upload through Google Ads

```
{
  "script_name": "google_ads_upload_video",
  "platform": "GOOGLE",
  "args": [
    "--url", "https://blob-url/video.mp4",
    "--title", "Synter AI Agent Demo"
  ]
}
```

### Step 3: Create Demand Gen Campaign

```
{
  "script_name": "google_ads_create_demand_gen_campaign",
  "args": [
    "--campaign-name", "YouTube - AI Demo",
    "--video-id", "dQw4w9WgXcQ",
    "--daily-budget", "50",
    "--geo-targets", "2840"
  ]
}
```

## Asset Requirements

Demand Gen campaigns require specific creative assets:

| Asset Type | Requirements |
| --- | --- |
| Headlines | 3 minimum, max 40 chars each |
| Descriptions | 2 minimum, max 90 chars each |
| Video | YouTube video ID (public or unlisted) |
| Logo | 1:1 ratio, 128×128px minimum |
| Business name | Max 25 characters |

## Real Production Campaigns
