The Loyalty Ladder — the theory behind this view
What it is. The loyalty ladder is a relationship-marketing model popularised in the early 1990s (Christopher, Payne & Ballantyne’s Relationship Marketing, building on Raphel’s ladder). Its premise: a customer base is not one mass but a sequence of rungs of increasing attachment, and marketing’s job is to move people up one rung at a time.
The rungs. Prospect — aware but has not yet bought. Customer — has bought once or occasionally; no bond. Client — buys repeatedly but transactionally, often price-led and open to competitors. Supporter — likes the brand and buys habitually, yet stays passive. Advocate — actively recommends the brand and defends it; some versions add Partner above. Each transition has its own mechanism — trial, habit, trust, identity, voice — and asking a rung for behaviour two rungs up (e.g. asking a Customer to advocate) typically backfires.
Why climbing matters. Retention is cheaper than acquisition, spend and share of wallet rise with attachment, and Advocates recruit new customers at zero media cost — so the ladder shifts budget from perpetual acquisition to graduation mechanics: onboarding, habit loops, loyalty programmes, recognition and referral schemes.
How this study uses it. An XGBoost classifier assigns each of the 2,030 respondents a rung from surveyed behaviour (frequency, spend, Kenz’up engagement, attitudes). The theory’s prediction holds in the data: patronage, spend, share of wallet, satisfaction and cross-sell openness all rise with the rung, while improvement demands and short-termism fall. The engagement’s tactical translation is one number: +1 visit per month per customer. Prospects were excluded by design and are recommended as the next study.
