Question 1

What is Cialdini's 7 principles of persuasion in marketing?

Accepted Answer

Robert Cialdini's 7 principles — Reciprocity, Scarcity, Authority, Consistency, Liking, Social Proof, and Unity — describe the psychological triggers that make people more likely to say yes. On landing pages, these translate to social proof sections, urgency signals, authority badges, and consistent messaging that reduces cognitive dissonance.

Question 2

How does the Fogg Behavior Model apply to landing pages?

Accepted Answer

BJ Fogg's model says that behaviour (like clicking a CTA) only happens when three things align: Motivation (the visitor wants the outcome), Ability (it's easy to take action), and a Trigger (a clear prompt appears at the right moment). Landing pages fail most often because they make action too hard (too many form fields) or don't trigger at the right moment (CTA buried below the fold).

Question 3

What is the difference between System 1 and System 2 in landing page design?

Accepted Answer

Daniel Kahneman's dual-process theory describes two modes of thinking. System 1 is fast, intuitive, and emotional — it forms a first impression of your page in under a second based on visuals and layout. System 2 is slow, deliberate, and analytical — it reads your copy and evaluates your claims. A high-converting landing page serves both: a compelling visual and clear value prop for System 1, and solid evidence and objection-handling for System 2.

Question 4

What cognitive biases affect landing page conversion rates?

Accepted Answer

Several biases have high impact on conversions. Loss aversion (losses feel ~2x as powerful as gains) means copy framing the cost of inaction outperforms benefit-only copy. The anchoring effect means showing a higher reference price before your actual price increases perceived value. The Zeigarnik effect (unclosed loops stay top of mind) explains why progress indicators and open-ended headlines work. The decoy effect makes a middle pricing tier look more attractive when surrounded by extremes.

Question 5

What are the Stanford Web Credibility guidelines for websites?

Accepted Answer

Stanford's Web Credibility Research Project identifies four types of credibility: Presumed (stereotypes about the org type), Surface (design quality), Earned (first-hand experience), and Reputed (third-party endorsements). For landing pages, the most actionable guidelines are: show real people behind the product, keep design polished, display verifiable credentials, and include third-party references like press or customer logos.

Question 6

What is friction point mapping in CRO?

Accepted Answer

Friction point mapping is the process of identifying every place on a landing page where a visitor's momentum toward conversion slows or stops. Common friction points include: cognitive friction (jargon, unclear value props), form friction (too many fields), trust friction (anonymous brand), and visual friction (competing CTAs, cluttered layout). Removing friction is often more impactful than adding persuasion elements.

Question 7

How do I know if my landing page is conversion-ready?

Accepted Answer

A conversion-ready landing page passes seven tests: it uses social proof and authority signals (Cialdini), it makes action easy and well-timed (Fogg), it communicates visually before the visitor reads a word (Kahneman System 1), it handles objections proactively (Kahneman System 2), it leverages loss aversion in its copy, it builds verifiable credibility (Stanford), and it's built for cold traffic rather than people who already know the product (Trust Ladder).

Does Your Landing Page Pass the Psychology Test?

Does your page show real evidence that other people have used and benefited from your product? (Testimonials, reviews, user counts, logos, case studies)
