Your store receives 10,000 visitors per month. With a conversion rate of 1.5% (Brazilian average), that's 150 sales. With a rate of 3%, that's 300 sales — double without spending an extra cent on traffic. Conversion rate optimization for e-commerce (CRO) is the cheapest revenue multiplier available.
15 CRO Tactics for Online Stores
Trust Tactics (Reduce Purchase Anxiety)
- Visible Security Seal at Checkout: SSL, Google Safe Browsing, store seal on Reclame Aqui
- Photo Reviews: Real testimonials with customer photos using the product convert 3x more than text-only reviews
- Clear and Visible Return Policy: “Returns and Exchanges” link in the cart — don’t hide it in the footer
- Extended Warranty: “Satisfaction guaranteed or your money back in 7 days”
- Chat or WhatsApp at Checkout: Someone available to answer questions at the time of purchase
Urgency and Scarcity Tactics (Without Being False)
- Visible Real Stock: “Only 3 units available” — when it’s true
- Recent Sales Counter: “X people bought in the last 24 hours” — using real data
- Free Shipping with Deadline: “Free shipping over R$ 199 — ends Sunday” with a countdown
Usability Tactics (Remove Friction)
- One-Page Checkout: Cart and payment on the same screen. Each extra step = -10% conversion
- PIX as Main Option: 40% of online purchases are PIX — with a 5% discount
- Functional Search: Predictive search with typo correction and product suggestions
- Smart Filters: By price, color, size, rating — the customer finds what they want in 3 clicks
Cart and Checkout Tactics
- Persistent Cart: The customer closes the site and returns 3 days later — cart intact
- Intelligent Cross-sell: “Customers who bought these shoes also bought these socks” (not random)
- Guest Checkout: Don’t force account creation. “Buy as a guest” prominently displayed
