How to Run Cross-Channel Ad Campaigns with AI in 2025

Managing ads across Google, Meta, LinkedIn, Microsoft, Reddit, and X is a nightmare of tab-switching, spreadsheets, and platform-specific nuances. Here's how AI agents are solving it.

The Multi-Platform Advertising Problem

If you're running ads for a B2B SaaS company, your media mix probably looks like this:

  • Google Ads: Capture high-intent search traffic
  • LinkedIn: Target by job title, company size, industry
  • Meta (Facebook/Instagram): Retargeting and broad awareness
  • Microsoft Ads: Bing + LinkedIn audience targeting
  • Reddit: Community-based targeting for niche audiences
  • X (Twitter): Thought leadership and tech audiences

Each platform has its own:

  • Campaign structure (Campaign → Ad Group vs. Campaign → Ad Set)
  • Targeting taxonomy (keywords vs. audiences vs. interests)
  • Creative specs (character limits, image sizes, video formats)
  • Bidding strategies (CPC, CPM, CPA, tROAS)
  • Attribution windows and conversion tracking

The Result?

A senior media buyer spends 60-70% of their time on platform mechanics—not strategy. Launching a campaign across 3 platforms takes 2-3 days of manual work. Reporting requires stitching together exports from each platform.

How AI Agents Solve Cross-Channel Advertising

An AI agent for advertising understands all the platforms and can translate your strategy into platform-specific campaigns automatically. Here's how it works:

1. Connect Your Platforms

Link your ad accounts via OAuth. The agent gets read/write access to create campaigns, pull performance data, and make optimizations. All tokens are encrypted; you can revoke access anytime.

2. Describe Your Strategy

Tell the agent what you want in natural language: "Launch a campaign for our API product targeting enterprise developers. $10K/month budget, optimize for demo requests."

3. Agent Builds Platform-Specific Campaigns

The agent translates your brief into campaigns for each platform—respecting each platform's structure, targeting options, and creative specs.

4. Dry-Run Validation

Before spending money, the agent validates campaigns via platform APIs. Catch targeting errors, budget issues, or policy violations before launch.

5. Launch & Unified Reporting

Deploy to all platforms with one approval. Get consolidated performance data across channels—no more spreadsheet stitching.

Platform-Specific Intelligence

The AI agent knows how to translate concepts across platforms:

BiddingTarget CPA, Max ClicksCPC, CPMCPC, CPM, CPV

Budget Allocation

The agent can distribute budget based on:

  • Funnel stage: More on Google (high intent), less on awareness channels
  • Historical performance: Shift to channels with better CAC
  • Audience overlap: Reduce spend where audiences duplicate
  • Platform minimums: Respect each platform's minimum budget requirements

Creative Adaptation

One message, adapted for each platform:
