Why C1 Matters More Than Just Traffic or Clicks
The payment conversion rate (C1) shows what percentage of your website visitors actually complete a purchase. It’s not about interest or engagement — it’s about actual revenue.
Here’s the breakdown:
C0 – conversion from visit to checkout start (e.g., adding to cart or entering an email)
C1 – conversion from visit to completed payment
Improving C1 means you're making more money from the same traffic — without increasing ad spend.
Checkout Optimization and Customer Journey Mapping (CJM)
A Customer Journey Map (CJM) helps you visualize every step users take — from discovering your offer to completing the payment.
A typical journey includes:
- Landing on the website
- Exploring your product or service
- Clicking “Buy” or “Checkout”
- Filling out the form
- Selecting a payment method
- Confirming the payment
Users can drop off at any stage — but most losses happen at the final step: the payment. And it’s often due to friction in the UX, not intent.
That’s where checkout optimization comes into play. It removes roadblocks for users who are already ready to pay. It’s one of the fastest ways to increase C1 and directly grow revenue.
Why You Should Optimize the Bottom of the Funnel First
Teams often focus on hero images, landing pages, or ad creatives. But the bottom of the funnel — the payment step — is where the fastest, most measurable growth happens.
Common Barriers During Checkout:
- Complex or unnecessary form fields
- Unclear total amount (especially with fees)
- Limited payment methods
- Transaction errors or delays
- Manual transfer requirements
The more your user has to think — the more likely they are to abandon checkout. Reducing friction in payment, especially on mobile, is crucial for improving C1 and reducing cart abandonment.
The Math Behind It
Let’s say your site gets 10,000 monthly visitors:
- C0 = 20% → 2,000 begin checkout
- Checkout-to-payment = 15% → 300 complete payment
- C1 = 3% (300 of 10,000)
Scenario 1: Increase C0 by 20% → 2,400 start checkout
Result: 15% of 2,400 = 360 payments → +60
Scenario 2: Keep C0 the same, but improve final conversion to 25%
Result: 25% of 2,000 = 500 payments → +200
Conclusion: Optimizing the final payment step through smart checkout optimization yields 3x more results than improving the top of the funnel by the same percentage.
Proven Ways to Boost C1
Simplify the Checkout Flow
Remove every non-essential field. Each extra input lowers your odds of conversion. Keep it clean and focused.
Show the Final Price Clearly
No surprise fees. No last-minute “plus network fees.” This is critical in cross-border payments and crypto transactions.
Offer Every Popular Payment Option
Users expect to see their preferred logo — Visa, Apple Pay, Google Pay, crypto, and other payment options. If not, they’ll bounce to a competitor who does.
Mobile-First Checkout Optimization
More than 50% of users checkout on mobile. Make sure your payment flow is scroll-free, zoom-free, and tap-friendly. Especially for crypto payments, UX on small screens is key to preventing cart abandonment.
Enable Biometric Payments
Let users authorize with Face ID, Touch ID, or autofill. Fewer taps = more completed payments.
Automate Recurring Payments
For subscriptions and digital products, one-click re-purchase is a game-changer. Don’t make users re-enter details every time.
Payment Diversity: From Optional to Essential
Users have different preferences and constraints. Some don’t have cards. Some don’t trust banks. Some only use Apple Pay. Some only pay with crypto.
Crypto is especially useful when:
- You're serving global customers
- Your audience values privacy
- You're in B2B or high-risk sectors
- Your customers want full control
Offering crypto can be the difference between a completed checkout and a bounce. But it must be implemented seamlessly.
Enabling Crypto Payments with CryptumPay
Crypto is powerful but comes with UX hurdles. For example, to send USDT on TRON, users need a small amount of TRX in their wallet (for example, Metamask) to pay gas fees. Without TRX, the transaction won’t go through.
That’s where crypto payment gateway CryptumPay makes the difference.
If the user doesn’t have the required native token, CryptumPay detects it and sends the required amount automatically. The token cost is added to the total bill in USDT, based on current exchange rates. The result? The user pays the fee — without dealing with technical hassles.
Other Key Benefits:
- One-click repeat payments via biometrics
- Fast integration: API, widget, or white label
- Full support for major tokens and networks
- Instant crypto payment setup — with zero risk
One-Click Repeat Payments = Higher LTV
Subscriptions, reorders, digital goods — these all thrive on repeat payments. CryptumPay stores your customer’s payment method and enables one-tap transactions, without manual re-entry. This directly boosts retention and customer LTV.
Why C0 Isn’t Enough
C0 shows how many visitors start the checkout process — but it doesn’t guarantee revenue. If users drop off before completing payment, all your marketing and CAC investments go to waste.
That’s why increasing C1 is always worth it, even if C0 stays the same. Remove UX barriers, improve checkout optimization, add payment options, and watch your revenue grow.
FAQ
What is C1 and how do you calculate it?
It’s the percentage of site visitors who completed a payment. Formula: (Number of Payments ÷ Total Visitors) × 100%
What payment methods improve C1?
Cards, Apple Pay, Google Pay, local options, and crypto. The more options, the better.
Why do users abandon payments?
Too many form fields, lack of payment methods, surprise fees, or technical errors.
Why are native tokens required for crypto payments?
They cover network fees. For example, TRX is needed to send USDT on the TRON network.
How does CryptumPay help?
It automatically adds required tokens to pay fees, simplifies the UX, and supports one-click payments. Setup takes just a few hours.
Final Thoughts
Increasing your payment conversion rate (C1) is one of the most direct ways to grow revenue. Unlike traffic or CTR, C1 proves whether your funnel truly delivers.
Simplify the checkout process, offer more payment methods, and enable fast repeat payments. Add crypto as a seamless option — not a gimmick — and solve one of the biggest drop-off points in ecommerce.
With tools like CryptumPay, you’re not just adding another button — you’re removing reasons to leave.
