Formula and method

CVR = (Orders / Visitors) × 100 ; Revenue per Visitor = Revenue / Visitors

Conversion rate measures the percentage of visitors who make a purchase. Revenue per visitor combines CVR and AOV into a single metric that captures full visitor value. CPA shows the ad cost to acquire each customer.

Common mistakes to avoid

Comparing conversion rates across different traffic sources — paid traffic converts 2-5%, organic SEO 1-3%, social 0.5-1%.
Not segmenting by device — mobile typically converts at 1.5-2% vs 3-4% for desktop.
Treating CVR as fixed — improving page speed, trust signals, and checkout UX can improve CVR by 20-50%.

Frequently asked questions

What is a good ecommerce conversion rate?

Average ecommerce CVR is 1-3%. Top quartile stores achieve 3-5%. Fashion/apparel averages 1.5-2%. Electronics is typically 0.8-1.5%. Specialty products can be 4-8% with strong brand intent. If you're below 1%, focus on CVR before scaling traffic.

How do I improve conversion rate?

Highest ROI improvements: faster page load speed (+1 second = -7% conversion), clearer CTAs, product photos quality, simplified checkout (remove form fields), social proof (reviews), and free shipping threshold. A/B test one change at a time.

What is revenue per visitor (RPV)?

RPV = Conversion Rate × Average Order Value. It is the single best metric for measuring store health because it combines both CVR and AOV. If RPV is $0.80, every visitor is worth $0.80 in expected revenue — your CAC must stay below this to profit.
