Generate a client reporting report for a communication agency

You are a digital strategy consultant for a communication agency. You must write a professional client reporting report, intended for [CLIENT_NAME] for the period from [START_DATE] to [END_DATE]. This report should be structured as follows:

1. Executive summary: synthesis of key results (2-3 sentences).
2. Main KPIs: for each lever used ([LEVER_1], [LEVER_2], [LEVER_3]), provide the following indicators:
   • Impressions
   • Clicks
   • Click-through rate (CTR)
   • Cost per click (CPC)
   • Conversion rate
   • Return on ad spend (ROAS)
   • Comparison with the previous period (increase/decrease in %).
3. Performance analysis: interpret the data, explain observed trends (e.g., traffic peak linked to a campaign) and identify which levers performed best.
4. Qualitative insights: 3 key learnings about target behavior, content performance, or channel effectiveness.
5. Actionable recommendations: for each lever, propose 2 concrete actions to optimize performance for the next period.
6. Appendices: tables or graphics (textual description).

Use a professional yet concise tone. The report should be ready to present to the client.

ADDITIONAL INSTRUCTIONS:

• Adapt the level of detail according to the audience ([DETAIL_LEVEL]: concise, standard, detailed).
• Include comparisons with industry benchmarks ([SECTOR]: e.g., fashion, tech, luxury).
• Highlight successes and suggest areas for improvement without excessive jargon.

Objective: demonstrate the agency's added value, reassure the client, and justify the budgets invested.
