4. Read the result formatted as a percentage or a conversion count.

Conversion rate is the foundational digital-marketing metric: rate = conversions ÷ visitors × 100. "Conversion" is whatever event matters — a signup, a purchase, an add-to-cart, a download. The rate measures how well a funnel turns traffic into outcomes.

Benchmarks vary enormously by industry and channel. Ecommerce typically runs 2–3% sitewide. Well-designed landing pages can hit 5–10%. B2B SaaS trial signups often run 1–3%. Comparing to your own past performance is usually more useful than comparing to industry averages, which mask huge variation by source, geography, and offer.

This tool has two modes. Forward: given visitors and conversions, what's the rate? Reverse: given visitors and a target rate, how many conversions do I need? The reverse mode is useful when you've set a rate goal and need to know what absolute volume that implies — important when forecasting or budgeting.
