About this skill
About Campaign report writer
Campaign reports often dump metrics without saying what worked, what didn't and what to do next. This skill calculates CTR, CPC, CPA and ROAS from your numbers, showing each formula so anyone can check them, and compares results with the goal. It identifies the best and worst performers, offers plausible reasons while keeping correlation separate from cause, and recommends three next actions. The output is a one-page report leadership will actually read, with a one-sentence headline at the top and data caveats at the bottom. To use it, paste the skill into your assistant and send campaign metrics (spend, impressions, clicks, conversions, revenue by channel or ad) and the goal; the reply opens with “Headline”.
