SOP: Add a per-user frequency cap to a returning-traffic smartlink

SOP: Add a per-user frequency cap to a returning-traffic smartlink

A push-traffic smartlink showed the same offer to the same users repeatedly. Returning users (3+ hits) converted at near zero but ate premium-offer weight.

Steps run:
— Step 1: Tag each click with a hit-count cookie + server-side counter.
— Step 2: Segment EPC by hit number: 1st hit $0.30, 2nd $0.14, 3rd+ $0.05.
— Step 3: Add a rule: hit-count ≥3 → rotate to a fresh secondary offer they haven't seen.
— Step 4: Reserve the premium offer for hits 1-2.

Outcome over 14 days: 3rd+ hit EPC rose from $0.05 to $0.13 by serving novelty. Premium offer conversion rate rose from 1.2% to 1.5% once repeat-burned users stopped diluting it. Blended EPC +14%.

Repeat weekly: re-check EPC decay by hit number; the cutoff (3rd here) varies by vertical.
