9. Bounce Rate: The percentage of visitors who leave your website without interacting with it.
   Formula: Bounce Rate = (Single Page Visits / Total Visits) × 100
   Why it matters: A high bounce rate may indicate issues with your landing page or audience targeting.

14. Frequency: The average number of times your ad was shown to a single user.
    Formula: Frequency = Impressions / Reach
    Why it Matters: Helps prevent ad fatigue by ensuring your audience doesn’t see your ad too many times.
