Additional Tips to Improve Your PPC Forecasting

    Use Google Ads Keyword Planner or tools like SEMrush to check current CPCs before you start.
  1. Adjust for Seasonality
    Plan for fluctuating conversion rates in Q4, holidays, or industry-specific peak seasons

    If your customers buy more than once, include LTV to improve the accuracy of your ROAS.
  1. Set Benchmarks
    If you’re unsure of your conversion rate, start with industry averages. For example:
  • Lead gen: 2–5%
  • eCommerce: 1–2%
