Conversion Rate Calculator
From conversions and visitors/impressions, compute the conversion rate (CR) — a core marketing and sales-funnel metric.

計算結果
重點速覽：Conversion rate = conversions / visitors x 100%. A 'conversion' is any goal you set (order, sign-up, add-to-cart, form). It is the most direct measure of funnel performance — higher CR means better traffic quality and monetisation. Improving CR (optimise checkout, landing, CTA, trust) is often cheaper than buying more traffic: 2% → 3% lifts orders 50% at the same visitors. WARNING: Read with the conversion definition and source; different channels/stages are not comparable. High CR with low AOV or high returns is not necessarily profitable — pair with AOV, CPA, ROAS. Education, not advice.
計算公式
轉化率 = 轉化次數 ÷ 訪客數 × 100%。
$$轉化率：$CR=\dfrac{Conversions}{Visitors}\times100\%$$$$$示例：$\dfrac{250}{10{,}000}\times100\%=2.5\%$$$使用說明
- Enter the number of conversions.
- Enter the visitors or impressions in the period.
- View the conversion rate.
不同轉化次數與訪客數下的轉化率
| 轉化次數 | 訪客 / 曝光數 | 轉化率 |
|---|---|---|
| 200 | 10,000 | 2% |
| 250 | 10,000 | 2.5% |
| 300 | 10,000 | 3% |
| 50 | 800 | 6.25% |
理財情境案例
案例一：計算網店的下單轉化率
某網店某月有 10,000 位訪客，其中 250 位完成下單。
轉化率 = 250 ÷ 10,000 × 100% = 2.5%。
解讀：每 100 位訪客中約有 2.5 位下單，這個數字落在電商常見的 1%–3% 區間。轉化率本身沒有絕對好壞，最實用的是與自身過往數據及同渠道基準比較，觀察每次優化 (改版、調整落地頁、優化結帳流程) 之後有沒有提升。
案例二：提高轉化率 vs 增加流量，哪個更划算？
某網店現有 10,000 訪客、轉化率 2%,即 200 張訂單。老闆想增加訂單，有兩條路：(A) 花錢買更多流量；(B) 優化網站把轉化率提升到 3%。
若走 B 路線，同樣的 10,000 訪客，轉化率 2% → 3%,訂單由 200 增加到 300，增幅 = (300 − 200) ÷ 200 = 50%,而且不需額外的獲客成本。
解讀：在不增加一分廣告費的情況下，單靠把轉化率提高 1 個百分點，訂單就多了五成。這說明優化轉化率 (改善漏斗、落地頁、行動呼籲、信任元素) 往往是回報極高的投入。實務上常先優化轉化、再擴大流量，讓每分流量預算更有效率。不過要注意，高轉化率若伴隨低客單價或高退貨，未必等於高獲利，宜配合客單價、CPA、ROAS 一併分析。
常見問題
What is a good conversion rate?
No absolute standard — it depends on industry, channel and the conversion definition. E-commerce order CR often runs ~1%-3%, while shallower goals like add-to-cart or sign-up are much higher. Best practice is to compare with your own history and same-channel benchmarks.
Is improving conversion or buying traffic better?
Both matter, but improving conversion is often more cost-effective. At the same traffic, CR 2% → 3% raises orders 50% with no extra acquisition cost. Practically, optimise conversion first, then scale traffic for efficiency.
Does a high conversion rate mean profit?
Not necessarily. CR shows only the proportion that converts, not order value, cost or returns. Heavy discounting may lift CR but thin margins; high returns shrink real conversions. Pair with AOV, CPA and ROAS to judge true value.
What is a 'good' rate — is there a standard?
There is no universal good number because CR depends heavily on industry, traffic channel and the conversion definition. Shallow goals (add-to-cart, free sign-up) convert far higher than paid orders; comparing order CR to sign-up CR is meaningless. E-commerce order CR of ~1%-3% is a rough reference only. Judge CR against your own trend and same-definition, same-channel benchmarks rather than an external 'standard'.
Does high CR equal profit?
No — a common trap. CR measures only the proportion, not the value or cost per conversion, which determine profit. High CR can coexist with low profit via: deep discounts (thin margin), low AOV, high returns (real conversions discounted), or high CPA (expensive traffic). Always view CR alongside AOV, CPA, ROAS, return rate and gross margin to see conversion quality, not just quantity.
