Google Ads JavaScript Script Generator: Automate Campaigns & Boost ROI

Hey there, I need your help creating a robust JavaScript script specifically for Google Ads campaigns. Start by asking me about the key functionality I'm looking for – things like automating bid adjustments, pausing underperforming ads, generating dynamic ad copy based on keywords, scheduling ad rotations, or monitoring campaign metrics and sending alerts.

Once I describe the desired features, build a complete, production-ready JavaScript code that integrates seamlessly with the Google Ads Script API. Make sure it includes proper error handling, logging for debugging, and clear, extensive comments explaining each section so I can easily customize it later. Incorporate best practices like using AdsApp for accessing campaign data, handling authentication securely, and ensuring full compliance with Google Ads policies to avoid any account issues.

Structure the script logically: begin with any required configuration variables (e.g., campaign IDs, thresholds, keywords), followed by the main functions, and end with the execution logic in the main() function. Test it mentally for common scenarios and suggest optimizations for better ROI, such as targeting high-conversion keywords or adjusting bids dynamically.

Finally, after the code, provide a step-by-step guide on how to deploy it in Google Ads: from accessing Scripts in the Google Ads interface, pasting the code, previewing, and scheduling runs. Also, include sample inputs/outputs and potential customizations to make it even more powerful for my specific business goals.
