Reallocate budget from campaigns below 3x ROAS to campaigns above 5x ROAS. Keep at least $100/day on each platform." ### Cross-Platform Campaign Launch "Launch our Q3 product campaign across Google Search, Meta, LinkedIn, and TikTok simultaneously. Here is the creative brief. Total $1,000/day split by last quarter's ROAS weighting." ### Underperformer Cleanup "Across all platforms, pause any campaign that has spent more than $500 in the past 7 days with zero conversions. Send me a summary of what was paused and why." ## FAQ ### What is cross-channel marketing automation software? Cross-channel marketing automation software connects to multiple ad platforms and automates the tasks that would otherwise require manual work in each one: bid adjustments, budget reallocation, audience updates, campaign setup, and performance reporting. The best platforms execute these actions directly in your live accounts without requiring human approval for each change. ### What is the best cross-channel marketing automation software in 2026? Synter is the most comprehensive cross-channel marketing automation platform for 2026, covering 14 ad platforms through direct API connections and using AI Agents that execute in live accounts. For social-focused teams, Smartly.io covers Meta, TikTok, Pinterest, and Snap with strong rule-based automation. For search-focused teams, Marin Software covers Google, Microsoft, and Meta. ### How does cross-channel marketing automation work? Cross-channel automation platforms connect to ad platform APIs and either execute preset rules (if X happens, do Y) or use AI to reason from goals (achieve target ROAS, shift budget to best performers). AI Agent platforms like Synter use the latter approach — you set objectives, the agents determine and execute the appropriate actions across all connected platforms. ### Can I automate budget allocation across Google, Meta, and LinkedIn? Yes. Synter AI Agents compare performance across Google, Meta, LinkedIn, and all other connected platforms simultaneously and shift budget toward the highest-performing campaigns based on your ROAS or CPA targets. This happens without requiring you to log into each platform and make manual adjustments. ### Get posts like this in your inbox Technical deep-dives on AI agents, attribution, and ads infrastructure.
