Conversion Optimization Conversion Optimization MCQ 3 — Questions and Answers
Question 1: Which element of a value proposition is most critical to communicate above the fold?
- Pricing tiers
- What the product does and who it's for (Correct answer)
- Number of customer reviews
- Company founding year
Correct answer: What the product does and who it's for
Visitors must immediately understand the product's purpose and relevance; without that clarity, no other element can drive conversion.
Question 2: What does a 'Taguchi method' refer to in multivariate CRO testing?
- A statistical method for testing many element combinations with fewer experiments (Correct answer)
- A heatmap analysis technique
- A pricing psychology framework
- A qualitative user interview protocol
Correct answer: A statistical method for testing many element combinations with fewer experiments
The Taguchi method uses fractional factorial design to estimate the effect of many variables by running a much smaller subset of all possible combinations.
Question 3: A SaaS company adds a live chat widget to its pricing page. Conversion rises 12% but average page load time increases 1.2 seconds. What is the most appropriate next step?
- Remove the widget since speed affects SEO
- Test a lazy-loaded or asynchronous version of the widget (Correct answer)
- Increase ad spend to compensate for slower speed
- Switch to a phone number instead
Correct answer: Test a lazy-loaded or asynchronous version of the widget
Lazy-loading the chat widget preserves the conversion lift while eliminating the performance penalty that can harm both UX and rankings.
Question 4: What is 'cognitive load' and how does it affect conversion rates?
- Server processing time that delays page rendering
- Mental effort required to process a page; higher load reduces conversions (Correct answer)
- The number of ads shown per session
- A measure of brand recall after a visit
Correct answer: Mental effort required to process a page; higher load reduces conversions
When a page demands too much thinking or decision-making, users abandon it — reducing cognitive load with clearer design and fewer choices improves conversions.
Question 5: Which statistical model is most appropriate when the conversion metric is binary (converted vs. not)?
- Linear regression
- Logistic regression (Correct answer)
- ANOVA
- Pearson correlation
Correct answer: Logistic regression
Logistic regression models the probability of a binary outcome, making it the correct choice for predicting conversion (yes/no).
Question 6: What does 'novelty effect' warn CRO practitioners about when reviewing test results?
- New users convert at higher rates than returning users
- A new variant may lift conversions temporarily simply because it is different, not because it is better (Correct answer)
- Test results differ between mobile and desktop
- Seasonal traffic spikes invalidate results
Correct answer: A new variant may lift conversions temporarily simply because it is different, not because it is better
The novelty effect means users engage more with any change at first; running tests long enough for the effect to wear off prevents false wins.
Question 7: An e-commerce store tests free shipping vs. a $10 discount of equal financial value. Free shipping wins. Which principle best explains this?
- Anchoring
- Zero price effect (Correct answer)
- Reciprocity
- Scarcity
Correct answer: Zero price effect
The zero price effect shows that 'free' triggers a disproportionately strong positive response compared to any non-zero price, even when the rational value is identical.
