Weekly Google Ads performance recap

Generate a weekly performance recap for my Google Ads account covering the last 7 days vs. the previous 7 days. List my accounts first and ask which one to recap if I have more than one. Include: spend delta, conversions delta, CPC trend, CTR trend by campaign, and every material mover (positive and negative) sorted by impact — don't cap the list, surface anything worth flagging. For each negative mover explain the likely root cause based on the data (search term shift, bid cap hit, audience saturation, etc.). Format as a concise stakeholder-ready briefing.
