Liking

Liking is Cialdini's fifth principle. The mechanism: humans are more easily persuaded by people they like — and liking is triggered automatically by familiarity, similarity, attractiveness, and being complimented.

In DTC ads, Liking is the lever behind UGC, creator partnerships, friend-style ad copy, and brand voice in general. It's the principle that makes "ugly" ads convert better than polished brand campaigns on cold traffic — the UGC creator looks like a friend, and you trust friends.

How it shows up

• UGC creators — "real" people the buyer pattern-matches to themselves or someone they know
• Founder-led content — the founder on camera builds liking through familiarity
• Friend-style copy — second-person, casual voice, no corporate vocabulary
• Familiar faces — repeat creator partnerships build liking through repeat exposure
• Compliments — "smart people like you" / "if you're already shopping outdoor decor, you have taste"

When it works

• Cold-traffic UGC — Liking is the primary persuasion mechanism on first-touch
• Categories with personal involvement — beauty, wellness, parenting, lifestyle
• Categories where credentials are unnecessary or overkill — apparel, food, decor

When it backfires

• Overdone compliments — flattery that doesn't earn its place comes off as pandering
• Forced similarity — UGC creators who clearly aren't part of the buyer's tribe (wealthy creator pretending to be a working mom) breaks Liking immediately
• Brand voice that's too casual — a luxury brand using "hey bestie!" loses the Authority + Status its category depends on

DTC example

The TJ Maxx outdoor-decor ad in AdRivela's fixture leans heavily on Liking. The narrator opens "I stopped by TJ Maxx and found…" — first-person, casual, talking like a friend who just discovered something. The unpolished moments ("I also picked. I picked up a few more pillows") add Liking because they signal authenticity.

The lever isn't free — Liking ads are harder to scale because they depend on the specific creator's voice. A UGC video that converts at $1.20 CPA from one creator might bomb from another.

• Unity — the "we" extension of Liking (shared identity rather than just appeal)
• Ugly-Native Aesthetic — the visual style that maximizes Liking by mimicking organic content
