Get answers to the most common questions on conversion rate optimization:
What is the difference between CRO and CX?
CRO and CX both turn your website into a helpful tool for educating and converting your users. However, there are a few key differences that can help you differentiate between the two.
| Aspect | CRO | CX |
| Objective | Increase conversion rates and achieve immediate goals | Build long-term satisfaction and loyalty |
| Scope | Focused on specific actions (e.g., clicks, purchases) | Encompasses the entire customer journey |
| Approach | Analytical and data-driven | Holistic and emotionally driven |
| Timeframe | Short-term adjustments for quick wins | Long-term strategy for sustained growth |
The best way to illustrate the differences is through the techniques you use. If your ecommerce site has a high cart abandonment rate, CRO tactics could include simplifying the checkout flow, offering free shipping, or adding trust signals like customer reviews.
However, if you want to enhance CX instead, that may involve creating personalized product recommendations, providing clear onboarding instructions, and ensuring prompt and friendly customer support.
Both strategies improve your website, but they use different techniques and target areas to do so.
What is an A/B testing timeframe?
A/B testing timeframe is the amount of time your test will run. Like your sample size, the timeframe can also vary depending on the element you want to test.
For example, you might test a new color for your CTA button for a month or longer. On the other hand, you would likely only run your subject line test for an hour or two before sending the winning one out to the rest of your subscribers.
How do I calculate an A/B test sample size?
Instead of learning an A/B test sample size formula, it’s a lot easier to use a free calculator to do the work for you.
There are a plethora of handy calculators out there that make determining your sample size a breeze, like this one from Optimizely.
Some calculators will also help you determine the perfect timeframe for your test. Once you’ve found a calculator you like, it’s time to enter some details to get your sample size.
What are some CRO test ideas for SMBs?
Some great CRO test ideas for small businesses are:
- Eliminate unnecessary form fields
- Add social proof to key landing pages
- A/B test CTA buttons, text, and locations
- A/B test page copy
- Conduct focus groups and online tests
