Costly Signalling
Displaying expensive, effortful, or hard-to-acquire traits signals high status or underlying value.
Why it works
Based on evolutionary signaling theory (Zahavi, 1975), costly signals reliably indicate quality because only those with genuine resources can afford them. High cost creates credibility - the expense itself proves the signaler's capability and commitment. This separates high-quality from low-quality actors through demonstrated investment (Spence, 1973).

Implementation tips
- Highlight genuine investments in quality, time, or expertise - never fabricate costs
- A/B test cost transparency vs mystique - sometimes specific numbers work better
- Use third-party validation to verify expensive claims (certifications, expert endorsements)
- Balance cost signals with value justification - explain why the expense matters
- Target audiences that value and can afford the premium positioning
- Ensure the entire customer experience matches the costly signal positioning
eCommerce fit
Medium Effective for luxury e-commerce and premium positioning, but requires careful audience targeting and authentic high-value delivery. Can backfire with value-oriented customers.
Caution
Only use with audiences that value and can afford premium positioning. Avoid appearing wasteful to cost-conscious customers. Ensure costly signals deliver genuine value, not just expense. Don't alienate broader markets with overly exclusive messaging. Verify all cost and investment claims are accurate.
