I run campaigns as a content creator and want a lean but reliable automation flow built inside n8n. Your job is to prepare a basic blueprint and first draft of the workflow that will: • Monitor my live Google Ads account, pause or exclude keywords that drive costs up without converting, and test fresh keyword ideas automatically so only the proven, good-value terms stay active. • Capture every new lead’s WhatsApp number and email (when provided) and immediately send a pre-written WhatsApp message plus a follow-up email. • Push a concise performance summary to me every day—impressions, spend, conversions, and a short note on which keywords were removed or added. Keep the setup as simple as possible: native Google Ads API calls, standard n8n nodes, and, if needed, lightweight HTTP or Webhook steps for WhatsApp and email delivery. Documentation should show where to place my API keys and how to tweak thresholds for “too expensive” keywords. I’m happy to refine later, but for now I just need the initial working flow and clear instructions so I can import it into my own n8n instance and start testing.
